the color filters inside the LCD are actually absorbing light that could otherwise be curing the resin. So an MSLA printer with a monochrome screen would use less energy and print faster.

A DLP 3D printer works by shining light into a vat of photosensitive polymer using a Digital Light Processing projector, curing a thin layer of the goo until a solid part has been built up.

Goeroptics unveils DLP 3D printing light engine - supporting resolutions of 4K and 1080P with a 3W output power.

Liquid Crystal Display (LCD) 3D printing functions similarly to DLP, but this approach leverages an LCD screen to mask the UV light and display the desired layer shape. Image Credit: Scott Bader ...
