| Rigid 4000 Resin contains glass particles, which strengthens printed parts. Maintain separate wash buckets to prevent glass particles adhering to parts printed with other resins. |
For parts printed in an engineering-focused resin (such as those in the Rigid, Tough & Durable, and Flexible & Elastic families), post-curing ensures that the parts reach their optimal mechanical properties and can function as designed. There is only one recommended post-curing time for Rigid 4000 Resin V1. |
