About this product

The fifth version of the general-purpose tough resin. It lists 60 minutes recommended and 120 minutes full at 60°C, the longest full cure of the common Formlabs resins in this table apart from Castable and High Temp V2.

Using this specific product

Formlabs Tough Resin V5 is listed here as the SLA photopolymer, post-cure settings version for 3D printing and functional parts. 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 functional parts, pay particular attention to accurate mixing, mold material, mass and room temperature.
  • At 60°C in Form Cure.

How to check readiness

Check the casting itself for flex or tack before demolding. The Form Cure settings list a post-cure of 60 minutes (recommended) and 120 minutes (full).

Avoid this mistake

Demold time is not necessarily full mechanical cure.
