Available Post-Processing Services

Post Processing Sanding


Sanding is used to remove material left over from support structures and to remove layer lines that may appear on the surface of some 3D-printed parts.

Vapor Smoothing Icon

Vapor Smoothing

AMT’s PostPro3D technology is a smart and automated post-processing solution for smoothing thermoplastic polymer 3D-printed parts. It provides a smooth finish that makes it easier to paint, coat or dye parts. It can also eliminate surface porosity and enhance their mechanical performance.

Post Processing Coating Icon


Coatings can provide corrosion resistance, enhanced adhesion qualities, surface protection, as well as improved visual and aesthetic properties.


Certain types of 3D-printed parts can be processed in a tumbler with abrasive media to provide a smooth, highly polished finish.

Additive Painting Post Processing Icon


Many types of 3D-printed parts can be primed and painted in a variety of colors to match your needs. Depending upon the additive technology used to build the parts, cleaning and surface preparation may be required before painting.

Additive Post Processing Dye Icon


Dyeing is a preferred finishing method for complex part geometries where painting may be impractical. In this post-processing method, parts are submerged in a water-based, colored dye, which is absorbed into the surface of the material.

Additive Plating Post Processing Icon


Electroplating can significantly boost the tensile strength of 3D-printed parts, making them almost as strong as metal parts.

Additive Decal Post Processing Icon


Press-on, adhesive decals can be used to add company logos, safety warnings and other graphic treatments to your 3D-printed parts.

Pad Printing Icon

Pad Printing

Pad printing uses an etched pad coated with a thin layer of ink and a flexible silicone pad to transfer a design from the etched design onto the surface of a part. It’s often used to add labels, logos and other simple information to the surface of parts.

CNC Machining Icon


Post-machining may be used for applications where a part must meet tolerances that are tighter than 3D printing can support. The part is first designed with a machinable surface that is slightly larger than needed. It is then machined to achieve the desired size and tolerance.

Insert Post Processing Icon


Often, 3D-printed parts are assembled with other components. To attach them, threaded inserts are often added to 3D-printed parts during post-processing. These may be heat staked or press fit into the part at the desired location and depth.

Assembly post processing Icon


In addition to 3D printing your parts, Fathom can assemble them for you, saving you valuable time and labor.

Case Studies //

Conformal Cooling

Conformal Cooling

A leader in industrial closures and packaging components was having assembly issues in the field due to warping of a particular part feature, which limited its functionality. Fathom identified the source of the issue and engineered a solution using DMLS and CNC machining post-processing to deliver results that saved the customer valuable time and money.

VSI Case Study

VSi Parylene

When Fathom’s Denver location built a stylish enclosure for VSi’s new vapor deposition machine, it not only condensed its product development cycle in half, but also provided extensive post-processing services, including sanding and grinding, powder coating, screen printing and mechanical assembly.
