Clear Cast Resin is a resin designed for investment casting, to directly print patterns that can be invested and cast. It has an extremely low thermal expansion, low ash, and no trace heavy metals.
Clear Cast Resin, paired with a latticing software, is recommended for use with larger parts, excelling at producing geometries thicker than 3 mm.
Clear Cast Resin is an accessible solution for directly printing casting patterns in house.

Clear Cast Resin on Formlabs SLA printers enables direct production of casting patterns in-house which reduces costs, decreases turnaround times, and improves flexibility in iterating and production.
Best in class thermal expansion for reliable casting shells with minimal cracking.
Clear Cast Resin achieves a clean burnout with low ash and no trace metals, leaving nothing to contaminate the final cast part. Clear Cast Resin is fully antimony free.
Create accurate patterns within 0.25 mm of the design. Compatible with any metal or shelling system, allowing foundries to cast new designs in record time.
