Alternate Post-Cure Solutions

Post-curing helps 3D printed parts achieve optimal material properties. Follow these recommendations to post-cure parts when using materials and systems that pre-date Form Cure.

Prior to the availability of Form Cure, some post-cure recommendations were developed based on widely-available hardware. The results of Formlabs’ post-curing comparison study show that using heat with a 405 nm light source during post-cure was superior to an equivalent level of lower wavelength light, such as 365 nm.

Form Cure uses a combination of active heating and 405 nm light—the same wavelength as the Form 2 laser—for the best results. Formlabs provides full guidance for using Form Cure, but Formlabs can only provide minimal guidance for alternate post-cure systems, which will produce different material properties and may require experimentation.

Recommended practices for the best post-curing results:

  • Completely wash and dry all parts before post-curing
  • When post-curing, ensure that the target temperature is reached before starting the cure lights and beginning the timer.
  • Rotate or flip parts midway to ensure an even cure if using point light sources. In larger cure chambers consider taking advantage of a solar-powered turntable to rotate your print as it cures.
  • For DIY solutions, build an enclosure around a powerful 405 nm lamp for an easy and effective solution. Keep in mind that heat plays a significant role in effective post-curing.
NOTE:These recommendations pre-date Form Cure. These time and temperature settings are strictly for post-curing materials and hardware that were available before Form Cure. For the latest recommended time and temperature settings, including newer materials, refer to the Form Cure time and temperature settings.
