Shot Peen Finish- Multi Jet Fusion 3D Printed Parts 

 You may ask yourself what is shot peening? It's a process where plastic beads are shot at a part to create a scratch resistant surface. When shot peening a part the plastic beads carry enough kinetic energy to cause plastic deformation don't be alarmed this doesn't hurt the part. What this does is create an area of stress on the surface of the part the indentations of the plastic beads create toughen the surface resulting in scratch resistance.

  The perfect application for Shot peening is where a part my experience some light abrasion but you still want the part to look nice . Overall shot peening doesn't really offer any enhancements to the parts material properties but it does offer scratch resistance and a better aesthetic finish. It works best with parts that are dyed black. Realistically the only downside to shot peening is that it can get stuck inside of small text engravings.
