Post-processing

Standard finishing included with every Tough 1500 order on SLA.

Included (standard)

✓
Support removal— Supports carefully clipped and contact points sanded smooth.
✓
IPA washing— Two isopropyl alcohol bath cycles to remove all uncured resin.
✓
UV post-curing— UV curing chamber completes polymerization for final mechanical properties.
✓
Sanding— Support witness marks sanded flush to consistent smooth matte finish.

Optional (quoted separately)

+
Wet sanding— Progressive wet sanding up to 2000 grit for near-polished surfaces.
+
Polishing— Multi-stage polishing for optical clarity on Clear Resin parts.
+
Assembly— Multi-piece builds bonded with structural adhesive. Seams filled and sanded.
+
Painting / priming— Filler primer and automotive-grade paint for presentation models.
