We use the latest generation of 3D printing technologies to meet tolerances of +/- 0.005” or +/- 0.002” per inch for SLS and +/- 0.004" or +/- 0.002" per inch for FDM, whichever is greater. Please see our Manufacturing Standards for more details.
SLS nylon is a durable material with great impact strength, medium flexibility, and high resistance to environmental factors, while FDM printed parts are available in a variety of high-performance plastics for applications that require resistance to the elements.
SLS can make a single part or component as easily as dozens of production pieces, while FDM is capable of producing end-use parts on-demand, increasing your throughput.
Geometries can be built more easily due to the 3D printing process, adding complexity without additional cost.
Parts can typically be shipped in 3-4 days, allowing for faster design iterations and speed to market.
SLS parts are de-powdered with a sand blasting process, followed by detailed manual de-powdering for more complex geometries. These parts are left with a surface finish comparable to a sugar cube. FDM parts are built with support material that is removed during post processing, leaving the surfaces with fine layer lines.
SLS parts go through the standard de-powdering process and are then media tumbled for several hours. These parts will have reduced grow lines and sharp edges may be softened by the tumbling process. The parts are left with an eggshell finish.
Xometry provides additional SLS, SLA, Multi Jet Fusion & FDM finishing options, including but not limited to: color dyeing, sanding, painting and plating to meet your needs. For examples of our additional finishes, please refer to our photo gallery.
The speed and versatility of Plastic 3D Printing lets product developers create physical snapshots of their designs through the iterative process.
Plastic 3D Printing can be used to create fully-functional prototypes, complete with moving parts, as well as all-in-one assemblies.
The high accuracy and consistency of Plastic 3D Printing makes it an ideal way to build large quantities of discrete or customized parts.
When designing models for 3D Printing, they must be saved with specific properties to ensure high-quality results. In this guide you will learn about the most common design mistakes that lead to unsatisfactory 3D models, and several tips you can use to avoid them.
Will It Leak, or Won’t It?
At Xometry, we get a lot of questions about accuracy and feature size when it comes to our many 3D printing processes. So as a team we ran several benchmark tests over various platforms and recorded the results.
Watch our new video for how to leverage the Complexity Paradox to actually lower production costs for more complex parts.
