Clear cast resin

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:

  1. Shell, lattice, and add drain holes to the part with a tool like Materialise Magics or Formware
  2. Orient, support, and slice the pattern in PreForm
  3. Print the pattern
  4. Wash, post-cure, and remove supports
  5. Plug any drain holes with wax or cure a small amount of Clear Cast Resin over the hole
  6. Attach the pattern to a casting tree and proceed with the rest of the casting process
