Post-curing achieves optimal printed part properties. Follow these recommendations to set up a post-cure station for Formlabs resins.
Post-curing enables parts to reach the highest possible strength and become more stable. Optimizing the strength of parts requires light and heat, and post-curing is particularly important for Formlabs’ range of functional resins. For example, post-curing is required for a successful burnout with Castable prints, and Flexible Resin doubles its strength with post-curing.
Formlabs’ post-curing solution, Form Cure, uses both heat and 405 nm light for a fast and highly effective post-cure. The 405 nm wavelength of Form Cure is identical to the Form 2 laser, making it an ideal post-curing tool for Formlabs materials. Include Form Cure in the printing process to finalize the polymerization process and stabilize the mechanical properties. When post-curing with other hardware, refer to the alternate post-cure recommendations.
Cure settings depend on the equipment you are using and the geometry of your part. The table below recommends post-cure temperature and the time required to cure in a 405 nm wavelength light source, such as Form Cure, for each Formlabs’ Resin.
Form Cure Settings
To post-cure previous resin versions with Form Cure, use the recommended time and temperature for the closest resin version number.
Post-cure settings are updated periodically, as materials are introduced and improved.
In general, over-curing is better than under-curing, so don’t worry about post-curing parts for extra time. Thick, bulky parts will require more time than these recommendations, because they are slower to heat to the proper temperature.
