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.

The photo below shows the three different finish levels available for clear SLA parts.  The part in the picture was built using DSM Somos WaterClear® Ultra 10122.

• E3 - Engineering Finish.
• E4 - Engineering Clear.
• A6 - Appearance Clear.

A print ready version of all of our finishing levels is available here.

The photos below illustrate some common finishing levels available for SLA parts.

Vacuum metalizing is a process of evaporating metals (usually aluminum) inside of a vacuum chamber to achieve a thin uniform metalized coating or layer. Prior to metalizing, your SLA parts will need to sanded smooth to an A5 appearance level finish.

Uses for vacuum metalized parts include:

• Lamp reflectors.
• Kitchen & bath fixtures.
• Kitchen utensils & cookware.
• Hand & garden tools.
