Form Wash V2 Settings
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.
SETTINGS
Form Cure V2 Settings
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 V2.
