Xometry Partner Guide

Version 6.2 April 2, 2020

COVID-19 Policies and Guidelines

We are paying close attention to the ever-evolving situation with COVID-19. Anytime we make guideline or policy changes, you will be notified via email. We will collect those notices and all other important information regarding policy changes and guidelines in response to COVID-19 in this section of the partner guide.

Stay-at-Home vs. Shelter-in-Place Mandates

If your area is under a Stay-at-Home mandate...

For the time being, your job limits remain unaffected. However, should you decide to close your shop we ask that you notify us as soon as possible.

If your area is under a Shelter-in-Place mandate...

In an abundance of caution, we have set your job limits to zero for the time being in case your operation is disrupted by this order. We need to take this step until further information is available about the extent of the shutdown.

If you are able to continue taking work, you can email work@xometry.com or call us at (240) 252-1138 to proactively to let us know.

Essential Supplier Status

Xometry supports virtually all US government prime contractors in the production of parts and prototypes for major defense programs as well as being a supplier to medical, food, aerospace and transportation industries. As a result, we are an Essential Supplier supporting “Essential Government Functions.”

As a member of out manufacturing network and a critical element of Xometry’s ability to support this responsibility, Essential Supplier status is necessarily extended to you.

If you need a specific notice for your individual business, please complete this form and we will send you documentation of your essential supplier status.

Remote Inspections

Due to COVID-19, all partners are now shipping directly to customers. Some partners will be required to do VQCs on standard inspection work. See our Remote Inspection section for more information on how VQCs work.

Sanitizing Parts

In an effort to do our part to slow the spread of COVID-19, we ask that you follow all best practices in sanitizing parts and shipping materials before sending to the customer.


Thank you for joining the world's premier on-demand manufacturing network. This guide outlines Xometry's Manufacturing procedures and policies that are required for all Xometry jobs. We recommend that you bookmark this page and refer to it whenever you have questions about our manufacturing requirements.

How it Works

The Xometry Instant Quoting Engine℠ analyzes the geometry of each part and determines a price, lead time, and design feedback instantly as a customer uploads their 3D CAD files. Its pricing and sourcing algorithms are securely trained on one of the largest datasets of custom part manufacturing jobs ever assembled using the latest neural net-based Machine Learning techniques.

Customers are able to order their parts directly from the instant quote in an e-commerce check-out experience, so by the time you see the job in your Partner Portal, the job is already secured. There is no need to quote and wait for a response.

Our sorting algorithm matches each job to partners based on unique requirements such as manufacturing process, finish specifications, shop certifications, inspection capabilities, and capacity. For example, a CNC lathe job with an ITAR certification requirement and a CMM inspection report will be matched to shops that meet those requirements. You are only able to view jobs that match your shop’s profile. Therefore it is imperative for you to fill out your shop capabilities as thoroughly as possible and to keep them up to date.

Setting Up Your Account

  1. Add your shop’s capabilities, including machines, finishing capabilities, and certifications. We will use that information to match jobs that are best suited to your shop.
  2. Due to the highly sensitive nature of our customers’ work, we’ll also ask you to sign an NDA agreement, and we’ll ask you to accept our Terms and Conditions.
  3. Fill out a short demographic onboarding questionnaire about your shop.
  4. Once you have filled out the required information, we will reach out to you with instructions for completing your first job with Xometry, which is the final step in the onboarding process.

Add CNC and Sheet Metal Machines

Onboarding Process

  1. Register: Once you complete your shop profile, the information will be reviewed by our Partner team to determine whether your capabilities are a match for our needs.
  2. Sign NDA and Accept T&Cs: Due to the highly sensitive nature of our customers’ work, we’ll also ask you to sign an NDA agreement, and we’ll ask you to accept our Terms and Conditions.
  3. Complete Shop Survey: Complete a short survey where you can tell us more about your shop. This information will be used to dictate the types of jobs you'll eventually see on your job board.
  4. Review Partner Guide and quiz: Review our Partner Guide (what you're currently reading) to understand our processes from taking a job through production, inspection, shipment, and payment. After reviewing the partner guide, you will need to take the associated Partner Guide quiz.
  5. Test part: Before receiving full approval into the Xometry Partner Network, all new partners are required to complete at least one test part for each technology they wish to take work for. Chosen parts will be sent to you via email upon completion of the partner guide quiz. Parts must be shipped back to Xometry for full inspection and approval. Once accepted, you will be able to submit an invoice for reimbursement for the cost. If you are ITAR Registered or ISO9001 Compliant we may accelerate the Onboarding Process to bypass the Test Part step.
  6. Account approval: Once the test part is accepted, the following actions will take place:
    1. You will complete an onboarding call with a member of our Partner Development team
    2. You will receive a link to the invoicing and payment system.
    3. Your status is updated to approved for the process you applied for.
    4. You are sent a confirmation email with detailed information.
    5. You will begin seeing job offers on your job board.

Partner Onboarding Process

Quality Management System

Please note that we require all Xometry partners to have an inspection tool calibration system and log in place before joining Xometry. We request that all partners also have — or are able to implement after joining — a Quality Management System in order to accept work.

Our Minimum Quality Management System Requirements are:

  • Establishment of a written Quality Policy
  • Measurement traceability using calibrated equipment
  • Control of documented information (ie record retention, revision control, control of documents)
  • Control of nonconforming parts
  • Quality objectives (i.e. On-Time Delivery, Quality, Communication)
  • Contract/Purchase order review to determine requirements (ie. specifications, manufacturing processes, quality, delivery) for products and services
  • Corrective action process (including root cause identification and documentation)

An example of a Quality Management System that meets the above requirements and is available for you to use as a template for your shop’s own QMS can be found HERE.

Xometry staff is available to provide coaching and materials on these requirements.

Ongoing Job Expectations

We guarantee our customers complete satisfaction. In order for us to deliver on that commitment, our expectations are 100% on-time performance and 100% quality in meeting the specifications. You will be expected to update the job status while the order is in progress. We will also expect you to contact us immediately if you are having any difficulties ordering materials, understanding dimensions, having issues with the files, or any production-related issues. Your initial job limit will be one (1) job with a $5,000 maximum value. The first several jobs are considered the probationary period. Our expectation is that you complete five (5) jobs perfectly in order to become an ongoing partner. Once you successfully complete five (5) jobs, your job and revenue limits will increase.

Navigating the Job Board

Xometry Job Board
Example Xometry Job Board (Click to enlarge)

Xometry will send an email notification to the account holder every time we post a job to your account (these notifications can be managed in your account settings). If you follow the link in the email, it will take you to our job board where you will be able to review the parts and their requirements. Xometry provides all of the job details (price, lead time, material, etc.) for you to view. You can also access the job board by visiting work.xometry.com and logging in. The 3D CAD files, drawings (if available), materials, and part quantities are all in one place.

Your job board has a selection of filters (see item #1 on the image) you can use to narrow down the jobs shown. Current filters include technology, material, finish, and job size. You also have the ability to sort your job board by price, ship by date, and match — which compares jobs on the board to those you’ve completed in the past to recommend jobs that best match previous work you’ve done. This video walks you through how best to make use of the job board search and sort filters to find the right jobs for your shop.

Over certain jobs, you may see a yellow "Recommended Job" icon (see item #2). Our job recommendation system uses a machine-learning algorithm that compares each new job on your board to past work that you've completed. Over time, the algorithm learns what types of jobs you tend to accept. The more work you complete, the more it learns about you. In making these recommendations, the system considers materials, quantity, and part complexity along with hundreds of geometric features that we extract from the CAD files. Jobs that are most similar to your past work will receive the highest scores.

You can use the built-in 3D viewer (see item #3) which allows you to get a close look at a part before deciding whether or not you want to accept the job. If the part looks good, be sure to "View Offer Details" to see more in-depth information about the job (see item #4).

If the price, lead time, and job requirements for a job are a fit, simply accept the job and a PO will be generated automatically. Some jobs will be listed at the top of the job board — such as exclusive Offers, offers with an updated price, or repeat work offers — so they are easy to find (see item #5).

Accepted Jobs & Manufacture of Parts

Job Status
Example Job Status (Click to enlarge)

Once a job has been accepted, it can be managed using Xometry’s web application where you can easily provide status updates, upload inspection reports, photos, Certificates of Conformance, Mill Test Reports, and finishing certs when required. You can also communicate directly with Xometry's Partner Tech Support Team if you have questions about dimensions or tolerances.

For CNC parts the standard finish is “as Milled”. Bead blasting is not permitted unless specified on the Purchase Order. Do not Bead Blast parts prior to Finishing unless specified on the Purchase Order.

For CNC and Sheet Metal parts, welding repairs are not permitted without permission from Xometry. Parts that are submitted that have been welded and repaired without prior approval will be rejected in Inspection. Partners who ship unauthorized weld repaired parts to customers will be subject to penalties.

Upon acceptance of the job, you are agreeing to manufacture the parts in your own facility. These parts cannot be made in alternative locations without explicit consent from Xometry. The only types of work that can be subcontracted without advance consent from Xometry are Grinding, Heat Treating, EDM, Welding and Finishing, and only where the subcontractors can meet the specific requirements of the drawings or specifications (surface finish, material properties, plating, painting, anodizing, chem-film, welding specs, etc.). Additionally, you are responsible for ensuring all subcontractors comply with the relevant Xometry Partner Terms & Conditions.

As a best practice, we recommend that when part non-conformances are caught by your internal QC Department, the parts should be sent back to the manufacturing floor for rework. After reworking, the parts should have a final check by the QC department before shipping.

Part Photos

Providing part photos is required to complete the online job workflow. This allows us to have clear documentation of a completed job prior to it being shipped to Xometry or directly to the customer, and should only take a few moments of your time. Please make sure the photos are clean and the subject is clearly in view.

Inspection and Quality Standards

Inspection Checklist
Standard Inspection Checklist (Click to enlarge)

Delivering high-quality parts to our customers is incredibly important to us. As a result, all new partners are required to ship directly to our facility so we can thoroughly inspect all work. Once you show us that you can ship quality work, you may become eligible for our Direct Shipping program, allowing you to ship directly to customers. More on that later.

For our partners — especially those that perform Aerospace, Defense and other ITAR work — it is important to understand Xometry’s Quality Clause Requirements as these clauses dictate the type of documentation that may be required for each job.

To aid you in this endeavor, we have prepared a Crash Course on our Quality Clauses. Watch the course and follow along with our downloadable Quality Clauses PDF guide.

We want our partners to be in the habit of checking their work. As such, we will require you to inspect each job based on the subsequent inspection requirements and complete the Xometry Inspection Report, which can be downloaded from your Xometry Account Profile in the Resources section. The checklist to the right is for reference and should not be shipped, but should be uploaded to the job board with the other documentation. Learn more about Xometry's Inspection and Quality Standards as well as see how to complete the Inspection Checklist and Report here.

When placing an order with Xometry, the customer must select one of the following options for inspection: Standard Inspection, Formal Inspection, CMM Inspection with Dimensional Report or First Article Inspection Report.

Inspection Documentation Requirements

Standard Inspection For New Partners Only

NOTE: Required only for new partners during the first five (5) jobs probationary period. For Standard Inspection requirements after the five jobs probationary period, see below.
Standard Inspection Report
Completed Standard Inspection report with ballooned print (Click to enlarge)

For all inspections, Xomery requires the use of calibrated tools.

For a Standard Inspection, the part material, features, and finish must be verified in accordance with the supplied CAD model or print and the requirements specified in the order, which will be clearly noted on the Purchase Order provided with each job. If no print is provided with the job, all dimensions will be measured at +/- 0.005”. We require each standard inspection to be inspected with Partner Inspection Form QA2F04, which can be found in the Resources section of the Partner Portal (Note: A CMM report can be used in lieu of the Xometry Inspection Report).

Once complete, the standard inspection documentation should be uploaded to the Partner Portal only and NOT included in the box with the parts.

Back to Top

Standard Inspection of a Part With a Provided Print

When a print is provided with the parts, it must be ballooned (by hand is acceptable) to correlate with the inspection report. Regardless of order quantity, 100% of all dimensions, attributes, dimensional locations, and print notes must be documented for the required sample size (See Statistical Sampling Table Below).

If not already on the print, the following needs to be checked and entered onto the Xometry inspection template:

  • Correct material to drawing spec
  • Material test reports if required
  • Plating and certification
  • Surface roughness (125 or better unless noted)
  • All inserts are installed correctly
  • All parts are deburred (as per print requirement)
  • All parts are clean and threaded holes do not have chips packed in the bottom

Back to Top

Standard Inspection of a Part Without a Provided Print

When a part does not have a print provided, we expect our partners to inspect the part to the CAD file and document the following specifications to verify correct setup and programming:

  • Correct material used
  • Material test reports if required
  • Plating and certification
  • Overall length
  • Overall width
  • Overall height
  • All hole locations, diameters and depths
  • Thread sizes and depths (note: thread depths are a frequent failure)
  • Threaded holes square to the surface (note: hole perpendicularity is a frequent failure)
  • Pocket/step depths (at least 1 depth per face)
  • Corner radii correct to model (note: this is a frequent failure)
  • Each face should have at least 1 feature check for X and Y location from zero edge
  • Surface roughness (125 or better unless noted)
  • All inserts are installed correctly
  • All parts are deburred
  • All parts are clean and threaded holes do not have chips packed in the bottom

Note: All changes made to inspection documents must have approval traceability. It is not acceptable to alter, obliterate, or otherwise cover over documented results. The usage of whiteout is not permitted. The presence of these conditions is a non-conformance. If an error is made, the error should be struck through with one line (leaving the original data discernible) and should be initialed by the person making the change.

Back to Top

Standard Inspection for Jobs Taken AFTER the First Five (5) jobs

The Standard Inspection reporting above does not apply. Instead, do the following for Standard Inspection documentation:

  • If a print is provided, redline it with inspection results for critical features. Upload this print and the completed Xometry Inspection Checklist to the Portal
  • If there is no print provided, choose and then verify that critical features are conforming. You will then only need to complete and then upload the Xometry Checklist to the Portal

Back to Top

Formal Inspection

For a Formal Inspection, Xometry requires the use of calibrated tools where 100% of all dimensions, attributes, dimensional locations, and print notes will be documented per our Statistical Sampling Plan based on ASQC Z1.4 2008 Level II (see below) to an Acceptance Quality Level (AQL) of 2.5% with zero rejects. To facilitate the inspection process, Xometry requires the customer to supply a dimensional print at the time the order is placed.

Inspections performed for a Formal Inspection shall be documented using the Partner Inspection Form QA2F03. Xometry QC will bubble the customers drawing and provide a pre-populated QA2F03 form. This inspection form documents the Tool ID#, Tool Type, calibration expiration used during the inspection. The absence of required tool information is considered a nonconformance. On jobs that require this type of inspection, this form will be emailed to the Partner from the Xometry Quality / Inspection Department. Add VQC@xometry.com to your email's whitelist so you never miss this important document.

Once the inspection documentation is completed, all forms should be uploaded to the Partner Portal as well as included in the box at the time of shipment.

Back to Top

CMM Inspection

A CMM Inspection with Dimensional Report is similar to a Formal Inspection where 100% of all dimensions, attributes, dimensional locations, and print notes will be documented per our Statistical Sampling Plan based on ASQC Z1.4 2008 Level II (see below) to an Acceptance Quality Level (AQL) of 2.5% with zero rejects will inspected using a Coordinate Measurement Machine (CMM). Once the inspection documentation is completed, all forms should be uploaded to the Partner Portal as well as included in the box at the time of shipment.

Back to Top

First Article Inspection Report (per AS9102)

A First Article Inspection Report (FAIR) follows the requirements specified in SAE Aerospace Standard (AS 9102) documentation. The purpose of the First Article Inspection is to provide objective evidence that all engineering design and specification requirements are properly understood, accounted for, verified, and documented. If completing a FAIR, you must maintain a quality record for customer review of accountability and planning, for performing periodic surveillance and audits to verify conformance, for evaluating root cause and corrective action for any non-conformances, and for problem investigations. Random sampling is based on ANSI/ASQ Z1.4 Level II to an Acceptance Quality Level (AQL) of 2.5%. A customer-specified dimensional print is required for a First Article Inspection.

FAIR will be documented using the AS9102 Inspection Report QA2F05. Xometry QC will bubble the customers drawing and provide a pre-populated QA2F05 form. This inspection form documents the Tool ID#, Tool Type, calibration expiration used during the inspection. On jobs that require this type of inspection, this form will be emailed to the Partner from the Xometry Quality / Inspection Department. Add VQC@xometry.com to your email's whitelist so you never miss this important document.

Direct Ship and Remote Inspections

Photo Inspection Chart
Photo Inspection Requirements (click to enlarge)

All new partners will ship work directly to Xometry for additional inspection. There will be cases where partners will be asked to do a remote inspection from time to time. A remote inspection is an inspection done through a complete inspection report as well as photos of certain dimensions supplied by our Virtual Quality Control (VQC) team. The image on the right is a copy of our exact requirements and guidelines for a remote photo inspection. Partners that achieve an excellent track record of producing high-quality, on-time parts will be approved to ship directly to our customers as a direct ship partner, with no inspection from us needed.

Back to Top

How Does the VQC Process Work?

First, a member of our quality team will contact you to share prints and specific highlighted dimensions of the parts. Once you’ve completed fabrication, we ask that you provide photo documentation of the following items:

  1. You measuring the highlighted part dimensions
  2. Any hardware installed and any part marking
  3. The finishing of the parts
  4. All faces of the part for a full sample size of each line item
    1. Tag with sample number visible in all photos

Next you’ll be required to:

    1. Complete a full inspection report (all dimensions on the print)
    2. Complete all CoCs, material certs, and finishing certs (as requested in the job details)
    3. Upload all inspections, certifications, and part photos to the partner portal. Please note that reports and certs MUST be uploaded in PDF format, not JPEG (pictures).
    4. Respond to vqc@xometry.com and let the inspector know all documentation has been uploaded

Once the inspector reviews the documentation for the job, they will respond with any additional information that is needed, or with the packing slip and shipping label. If you have any questions or concerns about this process, we are always here to help. Please reach out to our VQC team at: vqc@xometry.com.

After you complete your fifth (5) job and maintain a Quality Partner Success score of 80+, the Virtual Inspection (or VQC) will no longer be required for Standard Inspections. Non-Standard Inspections will still require VQC, as is the current process.

Material Test Reports

When material test reports (MTR’s) are requested by Xometry, they must state both mechanical and chemical properties of the material, lot or heat number, the specification which the material complies with (AMS, EN, ASME, ASTM, etc.). There also may be instances that the material must be DFARS and NAFTA approved by the USA or qualifying country, not counterfeit and also be mercury-free. These cases will be specified on the Purchase Order. The documentation must be uploaded to the job board and a copy must accompany the shipment.

Back to Top

Standard Material Certifications

Material Test Reports (MTR’s) that state both mechanical and chemical properties of the material, lot or heat number, and the specification which the material complies with (AMS, EN, ASME, ASTM, etc.).

DFARS Material Certifications

Material Test Reports (MTR’s) that state both mechanical and chemical properties of the material, lot or heat number, and the specification which the material complies with (AMS, EN, ASME, ASTM, etc.) and Country of Origin (COO) on cert proving material is from a DFARS compliant COO.

Domestic Material Certifications:

Material Test Reports (MTR’s) that state both mechanical and chemical properties of the material, lot or heat number, and the specification which the material complies with (AMS, EN, ASME, ASTM, etc.) and melt location is in the USA.

Material Traceability

When Material Traceability is required by Xometry, the document package must include the Material test report (material cert) from the manufacturer of the raw material and record showing each transfer of ownership/sale until the material has reached the final part manufacturer (pack slips). Mill Test Reports should always include heat lot number, inspector’s signature, as well as the chemical and physical analysis. The material specs on the Material Test Report must always match the material specs outlined in the customer’s drawing.

Back to Top

Plating and Finishing Document Requirements

In all cases when plating or specific finish requirements are defined, a copy of the certification stating the process and the applicable specification documented on the cert. must be sent with the shipment and uploaded with the MTRs. Example: If a print states “Clear Anodize to MIL-A-8625 TYPE II” the certification must state this wording.

Specialty Finishes added to parts will need a C of C from the finisher. This must contain:

  • The exact specs that the customer requested on the drawing or PO
  • Must have a signature
  • Other finishes — include any heat treatments or other specialty testing — that was done to the parts
  • Must have a Xometry part number or drawing part numberPlease note that failing to provide finishing certifications will negatively affect your Partner Success Score. If you are unclear as to what is required, please contact work@xometry.com with the job number and any other necessary details.

Back to Top

Certificate of Conformance

All part IDs require their own Xometry Certificate of Conformance (C of C) downloaded from the job portal and then uploaded after completion. Certification requirements will be identified on both the job board and the purchase order.

When parts are shipped — whether directly to the customer or to Xometry — C of C documentation must be uploaded to the job board and a copy must accompany the shipment. Lack of sending proper documentation will result in rejection upon receiving and potential return of parts.

Below are the fields that need to be filled out to complete a C of C:

Customer Name: Auto populates

Customer Part Name: Auto populates

Customer PO #: Auto populates

Customer PO Line #: Auto populates

Serial #: This information is on the Print or PO. If the customer has requested that serial numbers be used on the part, that information needs to be put here.

Customer Revision #: This is a revision of the print being used, and can be found on the print. This will need to be filled in.

Xometry Order ID: Auto populates

Xometry Part ID: Auto populates

Quantity: Auto populates

Material: If no print is provided this needs to be the material listed on the Xometry PO. Otherwise, this needs to be the specific material that is called for on the print or special notes from the customer. For instance, if Xometry PO states Aluminum 6061 T6 but customer print states Aluminum 6061-T6511 per AMS 4027, then the latter information should be entered here. When multiple specs are on the print you would use the spec of the material you purchased.

Material Lot number: Partner should add the material lot / heat number here since this is not known until the material is purchased and arrives on the partner’s dock.

Finish: This needs to be specific to the spec that the customer is requesting according to the print or notes from the customer.

Notes: The only entries that are needed here are the material specs, finishing specs, hardware specs, and assembly specs and numbers (if the part is assembled), that are not called out above.

Back to Top

Hardware Traceability Certifications

Please Note: A Certificate of Conformance is not an acceptable Hardware Traceability Certification.

When Hardware Traceability Certifications are requested by Xometry, material test reports (MTR’s), C of C from the Hardware supplier and all touchpoints back to the mill that produced the raw material need to be shown. This would show the PO from the partner shop to the Hardware supplier, the PO from the hardware supplier to the hardware manufacturer, then the PO from the hardware manufacturer to the mill that made the raw material. This paperwork should be provided for each different specification of hardware installed on the part. The documentation must be uploaded to the portal and a copy must accompany the shipment.

Hardware Traceability Documents can be requested from the supplier when the hardware is purchased.

3D Model, Job PO, and PDF Drawing Discrepancies

Xometry is a model-based company but there are times when a drawing may supersede what is derived from the CAD model. We put together a matrix to help you understand which file and which information we use as the source of truth to manufacture parts. All requirements will be derived from either the 3D CAD Model, the Job's PO, or the PDF Drawing itself unless otherwise specified in job notes:

3D ModelJob POPDF Drawing
Part Geometry--
Overall Length & Size--
Nominal Dimensions--
Holes/Feature Location--
Part Marking Type--
Inspection Requirements--
Part Quantity--
Tapped Holes/Threads Specification--
Inserts Specification--
Surface Roughness--

A print is required for supporting information that a model cannot capture. Examples of this are GD&T callouts, tap sizes, inserts – Helicoil, pem, etc., surface roughness requirements better than a standard Ra 125 micro-inches, and both general (tolerance block) or specific tolerances i.e. reamed hole size, press-fit, etc. If there are any questions regarding when to apply the information, please contact us via work@xometry.com.

Back to Top


General Guidance

If a CAD model only is supplied with the job, then the application-specific tolerances listed below apply. However, if a blueprint is provided, all tolerances of the print supersede the CAD model tolerancing.

Back to Top

Machining Metals

If only a CAD model is supplied the following tolerances apply to machined surfaces:

  • For features of size (Length, width, height, diameter) and location (position, concentricity, symmetry) +/- 0.005”
  • For features of orientation (parallelism and perpendicularity) and form (cylindrical, flatness, circularity, and straightness) apply tolerances as shown in the table below.
0-12”Tolerance of 0.005”Angularity +/- ½ degree
Over 12”-24”Tolerance of 0.010”Angularity +/- ½ degree
Over 24”-36”Tolerance of 0.015625” (1/64)Angularity +/- 1 degree
Over 36”-60”Tolerance of 0.03125” (1/32)Angularity +/- 1 degree
Over 60”Tolerance of 0.0625” (1/16)Angularity +/- 1 degree

If a blueprint is provided, all tolerances of the print supersede the CAD model tolerancing above. Any supporting dimensioning on blueprints such as GD&T callouts, tap sizes, inserts, specific surface roughness must be followed. Parts that do not require plating or surface treatment must be supplied “as machined” and at most be polished with scotch brite unless there are requirements for sandblasting, bead blast, shot peen, tumble, etc. The surface roughness requirement for “as machined” surfaces is Ra 125 micro-inches maximum. If no Class of Threads is called out on the drawing, Class 2 is assumed.

Back to Top

Machining Plastics

Unless otherwise specified by blueprints, all tolerances are +/- 0.010."

Back to Top

Sheet Metal

If only a CAD model is supplied, the following tolerances in the table below apply to surfaces:

Single Surface
Edge to Edge+/- 0.005”A
Edge to Hole+/- 0.005”B
Hole to Hole+/- 0.005”C
Hole Diameters+/- 0.005"D
Bend to Edge / Hole+/- 0.010”E
Multiple Surfaces
Hole to Hole/Edge; Edge to Edge+/- 0.030"F
Over Formed Part+/- 0.030"G
Bend Angle+/- 1 DegreeH

If a blueprint is provided, all tolerances of the print supersede the CAD model tolerancing above. Any supporting dimensioning on blueprints such as GD&T callouts, tap sizes, inserts, specific surface roughness must be followed.

Sheet Metal Flat Part
Flat Sheet Metal Parts (Click to enlarge)

Flat Sheet Metal Parts

Sheet metal parts that utilize stock material gauge thicknesses and require no bending or milled features. All flat sheet metal parts can meet a +/-0.005” (+/- 0.127mm).

Sheet Metal Bend
Sheet Metal Simple Bend (Click to enlarge)

Simple Sheet Metal Bend / One Surface

When designing parts with some type of bend with a standard bend radius, sheet metal tolerances are required to open. For simple bent parts, Xometry can offer a +/- 0.010” (+/- 0.254mm) tolerance for dimensions across a single bend. The bend radius itself is constrained to a +/- 1.0°

Multiple Sheet Metal Surface Bends
Multiple Sheet Metal Surface Bends (Click to enlarge)

Multiple Sheet Metal Surface Bends

For dimensions measured over multiple bends, Xometry can offer a +/- 0.030 (0.762mm).

Packaging Policy

Please ensure that all parts have been deburred and are free of dirt and oil prior to shipping. To ensure all parts are received by the customer unharmed and free of dings and scratches, we recommend the following packaging procedures below.

Back to Top

Selecting the Right Box

Single-Walled Boxes

  • Single-walled boxes should not be used for anything weighing over 20 pounds
  • This type of box is acceptable for additive parts (SLS, FDM, and Poly Jet)

Double-Walled Boxes

  • Double-walled boxes are the preferred box for CNC and sheet metal orders
  • Boxes that are over 24” should be double-walled
  • If at all possible do not pack parts weighing over 50 pounds into a single double-walled box. If you need to send parts in more than one box, you can print more shipping labels in the Partner Portal

Note: DO NOT RE-USE BOXES, USE BRANDED BOXES, OR INCLUDE ANY BRANDED ITEMS IN BOXES WITH XOMETRY PARTS. (Examples: Amazon boxes. boxes with logos or other company names, etc.)

CNC Packing and Shipping Guidelines

CNC Packing Guidelines
CNC Packing Guidelines (Click to enlarge)

The most important factor that determines how something should be packed is what material the part is made out of. Soft metals (copper, brass, and zinc) should be packed with more care. A minimum of 2 layers of bubble wrap (3/16” standard small bubble) is needed no matter the size of the part.- “Use Best Judgement” but minimally these small parts need to be put in individual poly bags. Zip Lock sandwich bags are not an acceptable substitute for poly bags.

The most important factor in deciding how to pack a part is that part’s wall thickness. Parts with 2 mm thickness or less need to be packed more carefully with additional internal support if possible using kraft paper or similar material. A minimum of 2 layers of bubble wrap (3/16” standard small bubble) is needed no matter the size of the part.- “Use Best Judgement” but minimally these small parts need to be put in individual poly bags. Zip Lock sandwich bags are not an acceptable substitute for poly bags.

Tips and Tricks to Packaging

  • Use Cardboard separators between heavy parts. This will prevent them from hitting each other during shipment.
  • Keep a minimum of 1 inch between the part and box.
  • If you can feel a sharp edge or corner of the part through the bubble wrap or foam, then add more packaging material.
  • Conduct a “Shake Test” on the box. If you can hear parts hit each other, or parts moving in the box, then it needs to be packed tighter. This can be achieved by adding more filler into the box or adding more bubble wrap to the parts.
  • Thin parts (less than ⅛”) should be sandwiched between 2 pieces of cardboard.
  • Large bubblewrap (½ inch or bigger) is not preferred for large parts. The voids between the bubbles will cause part-to-part contact, which will ultimately result in damage.

Completing the Packaging Process

  • Make sure the packing list is attached to the outside of the box and visible.
  • Inside the box: include CMM, FAI, the CofC, and any certifications or other formal inspection documents. All other documentation must be uploaded to the portal.
  • If you are direct shipping to customers: the Xometry sticker/decal should be attached and visible on the outside of the box and three (3) Xometry branded coasters should be included in each package that is part of a shipment.
  • All Shipments must receive an origin scan at a FedEx office location prior to the location's scheduled drop-off time.
  • Packages must not be deposited in a dropbox, or FedEx approved location (Walgreens, Safeway, etc) We do not consider an order complete, and you will be solely responsible for all losses if we do not receive an origin scan.
  • If we do not receive an origin scan, you will be solely responsible for all losses, and we will not consider the order complete.

Sanitizing Parts and Shipping Materials

Best practices to sanitize parts and shipping materials before sending to the customer:

  • Gloves must be worn during all manufacturing processes – no bare hands touching parts.
  • We recommend wearing masks or face shields.
  • Touching your face with gloves exposes the gloves to unsanitary conditions. Please swap gloves frequently and as soon as you touch your face / head.
  • If bare hands touch parts, then the parts must be cleaned using EPA-approved cleaning products. A list of acceptable products can be found here.
    • The most common products on this list include isopropyl alcohol (70% recommended) diluted bleach solution, or denatured alcohol.
  • If there has been suspected contamination or direct contact, partners should repeat the above sanitizing methods.

Shipping Instructions

  • Xometry provides delivery labels for all jobs unless otherwise noted. To utilize the Xometry shipping account, you must generate a shipping label through the online portal. To generate a shipping label, click the Ship button on the Current Jobs page to go to the Shipping page. Note that the Ship button will only become active on the Job Details page when all stages of the job status workflow have been completed.
  • Once on the Shipping page, click the Print Packing Slip button to generate a packing list. From there you will be prompted to generate a Shipping Label.
  • If you have multiple packages for the same order, you can create multiple shipping labels on the Shipping page. If you need assistance creating multiple shipping labels, please reach out to us at work@xometry.com

Xometry will not be responsible for organizing FedEx pick-ups. Partners are expected to organize the truck’s arrival and handle associated fees. To set up a pick-up, please make the label via our site then log into FedEx.com or call 1-800-463-3339 (1-800-GOFEDEX).

  • Partners with a FedEx Account: Can set pick-up via phone or online
  • Partners without a FedEx Account: Can set up a pick-up via the phone. Ask the representative to create a Site Profile for future pick-ups.

All shipments must receive an origin scan (e.g. they cannot be deposited in a dropbox). We do not consider an order complete, and you will be solely responsible for all losses if you do not receive an origin scan.

  • Labels are to be requested and/or printed only on the same day as the job will ship. Jobs should be updated to shipping complete ONLY if the package will receive an origin scan that same day.
  • By requesting/printing a label or by selecting “complete shipping” you are committing that it will be scanned and in transit on that day.
  • To avoid the risk of mislabelling the packages, please print labels as close to the time of packaging as practical and confirm that the correct label is affixed to the box.

Invoicing and Payment

Before you tell us, we know! This is the most important section. Xometry strives to pay all of its Manufacturing Partners in a timely manner. We use a third-party service to manage our invoicing and payments called Concur. For more information about Concur, please see our invoicing and payment FAQs in the Partner Portal's Invoicing section.

Back to Top

  • Where do I sign up and who should register? Upon acceptance into the Xometry Partner Network, you will be provided a form to fill out your banking information. Our Accounts Payable Department will send you an invitation to Concur at some point between form completion and the shipment of your first Xometry job. If you do not receive this invitation from Concur, please reach out to work@xometry.com
  • When will I receive payment? Xometry pays valid invoices twice a month on the 14th and 28th day each month as long as those days fall on a business day. If not, they will be paid on the first business day following those dates. Payment processing occurs in the Eastern time zone (EST and EDT). The payments will be issued according to the schedule on the right.
Invoice submittedPay date
10th - 23rd14th
24th - 9th28th

Example: An invoice submitted on January 15th will be paid on February 14th.

  • The following conditions make an invoice valid:
    • It must be submitted through Xometry’s service provider after Xometry is properly notified the parts have shipped with the tracking information provided.
    • The invoice is received not prior to shipment and no later than 30 days after part shipment from the Partner.

If you have any additional questions about how to use the third party website or need assistance signing up, please reach out to us directly via work@xometry.com and someone will be in touch as quickly as possible!

  • How do I submit invoices? Invoices must be submitted via email, as individual attachments, to partnerinvoices@xometry.com. Refer to this guide of best practices for submitting and tracking invoices. Please note that a Concur account is not required to send an invoice, so if you have not yet received your invitation, you can still send an invoice via email.
  • How do I view the status of my invoice? To check the status of an invoice, use the Search function towards the middle of the page on your Concur Dashboard. Search for invoices with amounts greater than zero to populate results on the right-hand side.

Reworks and Quality Issues

If the parts delivered by a Partner do not pass our inspection process due to quality issues, the PO for that job will be placed on hold until there is a resolution. If reworks must be done by Xometry to make the part acceptable for the customer, the price of those reworks may result in a chargeback. If the customer accepts the parts without the need for reworks, the PO will be taken off hold and the Partner will be paid according to our payment terms. If the parts are rejected and a resolution cannot be found, the PO will be canceled.

Partner Success Score

Your Partner Success Score (PSS) is a measure of factors that are critical to delivering customer satisfaction that ensures your success on the Xometry network. We track a number of metrics to measure the quality of your parts, the timeliness of parts shipped, engagement with your Partner Portal and job board, as well as communications about active jobs.

The specifics of our scoring system are proprietary. However, please note that being late on deliveries or shipping parts with specification defects will affect your score severely. At a minimum, we use the last 30 days of data to calculate your score. We’ll go back as far as needed to get to a sample size of 10 jobs, but won’t use any data over 6 months old. This means that being a long-time partner, taking high-value jobs, and taking many jobs can all help your score. And being new to the platform or if you have limited capacity will not count against you either. You can improve your score with every new job you complete.

Scores will be recalculated daily and available to you on the Partner Portal. Your Partner Success Score determines the number and type of jobs you see as well as the bonuses you get as part of the Partner Success Bonus program. Please note, the Xometry Partner Bonus Program is currently only available to partners who do CNC, sheet metal, or 3D printing work.
