For cost reasons, I would like to build a DIY Form Cure until I have a bit of money together again. The basic structure with a food dehydrator for temperature control is clear.

However, I’m not sure which 405nm LED I should install. So how many watts and how many LEDs. In an older white paper from Formlabs, 125 mW/cm2 is recommended. As far as I know, the current Form Cure has two LED strips and a spotlight (bottom) with a total LED power of 39 watts (9.1 watts LED radiant).

How do I get as close as possible to the Form Cure setup in terms of LED mW/cm2 with the same dimensions of the chamber? According to the white paper, too much mW/cm2 should also be detrimental.

I appreciate any tips! 🙂
