How long should Formlabs Rigid 10K Resin be left to cure?
Short answer
Cast-and-demold plan
Gel, demold and full cure are separate days
- Mix the SLA glass-filled resin, post-cure settings to ratio and pour
- Wait for the demold time
- Sand or finish after full cure
This product’s stated stages Quoted at 140°F
- Curing period1 hour to 1 hour 30 min
Worth noticing: The manufacturer states only one timing here (curing period, 1 hour to 1 hour 30 min); nothing else is inferred.
Common mistake: Demolding early and leaving a soft, tacky casting that never fully hardens.
Project stage ladder
Demolding, handling, finishing and final use may occur at different times
For 3D printing, high-stiffness parts, and tooling, identify which stage the stated period 1 hour to 90 minutes milestone actually unlocks. Earlier handling does not prove final cure.

Using this specific product
Formlabs Rigid 10K Resin is listed here as the SLA glass-filled resin, post-cure settings version for 3D printing, high-stiffness parts, and tooling. For casting resin, the useful question is not simply whether the surface looks finished—it is whether the exact next-action milestone shown above has been reached.
Before you start
- Confirm the package says SLA glass-filled resin, post-cure settings; related versions can use different timing.
- For 3D printing, high-stiffness parts, and tooling, pay particular attention to accurate mixing, mold material, mass and room temperature.
- At 70°C for the recommended setting and 125°C for the thermal post-cure.
How to check readiness
Check the casting itself for flex or tack before demolding. The Form Cure settings list 60 minutes at 70°C as recommended and 90 minutes at 125°C as the thermal post-cure.
Avoid this mistake
Demold time is not necessarily full mechanical cure.
