Post-processing

Standard finishing included with every Frosted PMMA order on Industrial SLA.

Included (standard)

✓
Support removal— Heavier supports cut with flush cutters and contact surfaces sanded smooth.
✓
IPA washing— Solvent baths to remove uncured resin. Extended wash times for large parts.
✓
UV post-curing— Large-format UV curing chamber. Longer cycles for thick-walled parts.
✓
Sanding— Support marks sanded flush. Presentation models get full surface sanding.

Optional (quoted separately)

+
Wet sanding— Progressive wet sanding up to 2000 grit for near-polished surfaces.
+
Polishing— Multi-stage polishing for optical clarity on Optical Clear parts.
+
Painting / priming— Filler primer and paint for architectural models and display pieces.
