Hello Candi,
You should be able to produce .2mm features with LOM. After all the laser
beam spot size is usually within .13-.15mm. The XY positioning system's
resolution is a lot better than that. You probably need to define what you
mean by a feature. Would it be a radius of a minimum circle, a radius at a
corner, a minimal wall thickness?
Best regards,
Michael Feygin

Hello Candi,
On the list you mentionned wax jet printing with 0.2 mm,
you need to say 0.013 mm with the Pattern Master from Solidscape
With my best regards
