Carbon DLS Finishing Options
Unfinished
With unfinished, you get varying aesthetics based on build orientation. Dots or standing nibs remain evident on the bottom of the part from the support structure remnants.
Natural Finish
With natural finishing, you get varying aesthetics based on build orientation. Standing nibs are sanded flat.
