3D Printing Services

We use the latest additive manufacturing processes to build functional prototypes and end-use parts in more than 50 different metals and plastics.

Selective Laser Sintering

How Does Selective Laser Sintering (SLS) Work?

Selective Laser Sintering (SLS) is a powerful 3D printing technology that produces highly accurate and durable parts that are capable of being used directly in end-use, low-volume production, or for rapid prototyping.

An additive manufacturing layer technology, SLS involves the use of a high power laser (for example, a carbon dioxide laser) to fuse small particles of plastic powders into a mass that has a desired three-dimensional shape. The laser selectively fuses powdered material by scanning cross-sections generated from a 3-D digital description of the part (for example from a CAD file or scan data) on the surface of a powder bed. After each cross-section is scanned, the powder bed is lowered by one layer thickness, a new layer of material is applied on top, and the process is repeated until the part is completed.


Stereolithography

How Does Stereolithography (SLA) 3D Printing Work?

Stereolithography (SLA) is a powerful 3D printing technology that produces extremely accurate and high resolution parts that are capable of being used directly in end-use, low-volume production, or for rapid prototyping.

SLA is an additive manufacturing process that focuses an ultraviolet (UV) light on a vat of photopolymer resin. It offers higher resolution printing than many other 3D printing technologies, allowing customers to print parts with fine details and surface finishes. SLA 3D printing is a highly-versatile platform for making custom parts in prototype and production settings; often acting as a stand-in for injection molded plastic parts.

Why SLA Printing With Xometry?

Xometry will offer both standard and high-resolution options for fine detail parts, and can also print larger sized parts and products, with some materials offering up to a 58" inch build area. In addition, Xometry's manufacturing partner network allows us to offer a larger variety of materials than other 3D printing companies - we offer a wide range of both Accura and Somos brand materials.

Fused Deposition Modeling

How Does Fused Deposition Modeling Work?

Fused Deposition Modeling (FDM) is a 3D printing technology widely known for its speed, accuracy, and competitive cost. A machine precisely extrudes melted plastic filament to create a part. Parts are very rigid, especially compared to Selective Laser Sintering (SLS), which makes them a great fit for projects with a rigidity requirement.

Producing parts in FDM is broken up into 3 steps, which includes pre-processing, production, and post-processing.

PRE-PROCESSING:
Printer software slices 3D CAD file into layers. For each slice, the software then converts the data into machine code that determines tool paths for the machine to follow.
PRODUCTION:
An extruder head extrudes liquefied plastic filament along the tool path layer by layer until the part is completed bottom-up.
POST-PROCESSING:
Support material is removed by either dissolving it in water, or breaking it off. More custom finishes such as tapping, inserts, etc. are then applied.

Why Work With Xometry For FDM?

Our FDM solution offers large build volumes up to 24″ x 36″ x 36″, a variety of colors, and a diverse selection of production-grade thermoplastics ‒ from ABS to Polycarbonate to Ultem.


Direct Metal Laser Sintering

How Does Direct Metal Laser Sintering Work?

By definition, Direct Metal Laser Sintering (DMLS) is an Additive 3D metal printing technology that builds prototype and production metal parts from a CAD file using a laser to selectively fuse a fine metal powder in either stainless steel or aluminum materials. A DMLS machine is capable of producing highly complex features and all-in-one assemblies using metal materials that would be difficult to achieve with subtractive manufacturing techniques.

Our DMLS printing service typically offers build volumes up to 250 x 250 x 325 mm, but we may be able to accommodate larger part volumes upon request in the quote. (See our Manufacturing Standards for more details) Find out the cost of the parts you need using DMLS or compare the costs of DMLS vs. SLS. Get a free instant quote today.


PolyJet 3D Printing

How Does PolyJet 3D Printing Work?

PolyJet 3D is a 3D printing technology known for its customizable material properties and excellent surface finish. It works by jetting UV curable resin onto a build tray in a process that is somewhat similar to inkjet printing. PolyJet 3D printing offers one of the most advanced industrial 3D printing solutions available, producing parts with incredible precision and speed. It also supports a wide variety of build materials.
