Product Description
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.
Form 4(B)L print settings are in progress, view the settings roadmap to see when settings for this material will be available on the Form 4(B)L.
Why Choose Clear Cast Resin?
Clear Cast Resin is an accessible solution for directly printing casting patterns in house.
Accessible pattern production 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.Low Thermal Expansion
Best in class thermal expansion for reliable casting shells with minimal cracking.Clean Burnout
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.Accurate and Versatile
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.
Workflow for 3D Printing Investment Casting Patterns
3D printed patterns can be used to directly replace the molded wax patterns typically used for investment casting allowing for complex geometries, and faster iterations without dedicated tooling. The process for creating a 3D printed pattern is typically:
- Shell, lattice, and add drain holes to the part with a tool like Materialise Magics or Formware
- Orient, support, and slice the pattern in PreForm
- Print the pattern
- Wash, post-cure, and remove supports
- Plug any drain holes with wax or cure a small amount of Clear Cast Resin over the hole
- Attach the pattern to a casting tree and proceed with the rest of the casting process
