Post-Processing

Form Wash (2nd Generation) Settings

DURATION
5 min in IPA

NOTES

Parts should be washed for 5 minutes in IPA or ethyl alcohol (concentration of 91% or higher). Immediately afterwards, dry the part thoroughly using compressed or forced air. Spray (or rinse) parts with fresh IPA or ethyl alcohol, then dry again using compressed or forced air.

Form Cure (2nd Generation) Settings

  • DURATION
    3 min
  • Temperature
    Ambient

NOTES

It is highly recommended to cure parts - this will significantly reduce any potential defects during casting. Cure for 10 minutes without heat in Form Cure or equivalent third-party curing machine. Cure for 3 minutes without heat in Form Cure (2nd Generation).
