Finishing Levels
We recently made some additions to our finishing levels. Download the print ready pdf here:
Engineering Finishes - Overview
E2: Minimal cleanup for all processes.
SLA: supports removed.
Machining: burrs removed.
Casting: gate and flash removed.
E3: Part is lightly sanded and/or bead or vapor blasted to minimize evidence of the build process and achieve consistent finish.
E4: This is an upgraded E3 with customer specific instructions. Example: further cleanup, fitting, clear coating for “engineering” level clarity etc. The end result is still considered an “engineering” model.
Appearance Finishes - Overview
A5: Part is sanded smooth on exterior surfaces, eliminating evidence of the process where necessary, and fitted if required. Part is primed and ready for final paint or rubber mold if part is being used as a pattern.
A6: Part is sanded smooth on exterior and interior surfaces and clear coated or polished for appearance purposes.
