Re: To those using UV Dlp mod. Have you guys seen any damage..
Are you referring to .5 watt/cm² watts per square?

- The other issue we have run into is the waste heat converted by a lamp. Compact designs require lots of airflow to keep the electronics cool.
The heat may also be conveyed to the photopolymer in the vat to reduce the viscosity via a heatpipe. If you use LED's then you can just add a cartridge heater to the vat.
