Notes Notes
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.
