In this design and manufacturing tips video, Xometry's Greg Paulsen, Director of Application Engineering, dives deep into the world of 3D printing surface finishes. He explains what each of Xometry's six additive manufacturing processes is, what kinds of surface finishes you can expect from each, and important considerations to help you select the right process and finish for your project. 

Here are some key sections in the video:

0:33 Xometry's 3D Printing Processes 
Includes how each process builds parts and how this affects the range of surface smoothness you can expect from each process 

2:45 Diving Deeper: SLS and HP Multi Jet Fusion
Includes the effect and efficacy of color dyeing

5:02 Diving Deeper: Fused Deposition Modeling
Includes the difference in layer heights depending on the FDM machine size

6:48 Diving Deeper: PolyJet 3D and SLA
Includes the range of digitally engineered materials available and the effect of post-processing on surface finish consistency 

10:09 Diving Deeper: Specialized Finishes
Includes exaggerations of a part's natural surface finish and the effect of build orientation of the surface finish
