Castable resin for jewelry casting. Burns ash-free and has low thermal expansion. Ideal for pieces that require printing fine details.

SKU: N/A Categories: ,


We have developed Spot-IC investment castable resin in collaboration with several professional jewelers using a range of investment casting processes. The design incorporates critical features:

  • Ash-free burn-out
  • Hardness and flexibility
  • Low thermal expansion
  • Posibility to post-process the printout

We have tested several burn-out schedules. From Gold Star Omega+, Kerr Satincast and R&R Plasticast and all give positive results with long hot end stages (>650ºC) during burn-out. You can also follow our burn-out recommendations at the Technical Docs section.

This castable resin is presented in yellow or green to provide better detail of the printed parts for filigrae work.

Spot-IC has a shelf life of 12 months. Keep the container tightly closed in a dry and cool place.
