Get Subpixel Printing With a DLP 3D Printer

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. Generally, the resolution of the print is determined by the resolution of the projector, and by the composition of the polymer itself. But, a technique posted by Autodesk for their Ember DLP 3D Printer could allow you to essentially anti-alias your print , further increasing the effective resolution. The technique works by using grayscale anti-aliasing on the image projected for each layer. The dimmer gray light results in the polymer taking longer to solidify. Therefore, if it’s used in key points, it can smooth out the print along the edges. It’s similar to how TrueType fonts, and other graphics display techniques, visually smooth out the edges of fonts and graphics in order to give t...
