Draft Resin
SLA photopolymer, post-cure settings · US · manufacturer-sourced
How long should Formlabs Draft Resin be left to cure?
Short answer
Cast-and-demold plan
Gel, demold and full cure are separate days
- Mix the SLA photopolymer, 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 period5 minutes
Worth noticing: The manufacturer states only one timing here (curing period, 5 minutes); 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 and fast prototypes, identify which stage the stated period 5 minutes milestone actually unlocks. Earlier handling does not prove final cure.

Conditions & fine print
- Stated conditions: 140°F (60°C)
- Printed parts are washed and dried before post-cure. Follow the current Formlabs material data sheet for your printer and firmware.
- Region US. Formulas can differ between countries; check your container.
- Curing period complete: No heat for better elongation, or 60°C for better ultimate tensile strength.
- Entered from the cited manufacturer documentation. Check the current label for the exact formula and region. Report outdated information
- Actual results depend on preparation, thickness, ventilation, temperature, humidity, mixing and substrate.

About this product
The fastest post-cure on the list: 5 minutes. The page offers two options with the same time, one with no heat for better elongation and one at 60°C for better ultimate tensile strength.
Using this specific product
Formlabs Draft Resin is listed here as the SLA photopolymer, post-cure settings version for 3D printing and fast prototypes. 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 photopolymer, post-cure settings; related versions can use different timing.
- For 3D printing and fast prototypes, pay particular attention to accurate mixing, mold material, mass and room temperature.
- No heat for better elongation, or 60°C for better ultimate tensile strength.
How to check readiness
Check the casting itself for flex or tack before demolding. The Form Cure settings list a post-cure of 5 minutes.
Avoid this mistake
Demold time is not necessarily full mechanical cure.
Questions
How long should this product be left to cure?
Formlabs states: The Form Cure settings list a post-cure of 5 minutes. Conditions: No heat for better elongation, or 60°C for better ultimate tensile strength.. These are the manufacturer’s stated times, not a guarantee.
Does Draft Resin post-cure need heat?
Only if you want better ultimate tensile strength. The settings list 5 minutes with no heat for better elongation or 5 minutes at 60°C for better strength.
What affects how long this product takes to dry or cure?
Printed parts are washed and dried before post-cure. Follow the current Formlabs material data sheet for your printer and firmware. Follow the product label for your conditions.
