How Photo-Polymer 3D Printers work

Envisiontec Perfactory Micro@3D Printer World Expo, Burbank 2014.

An explanation of how photo-polymer 3D printers work. The UV light image is projected from underneath the liquid resin to make the resin solid as a layer shape. It is lifted out of the resin layer by layer as it is printed on the elevating platform that it is attached to. This type of 3D printing is good for very fine detail and high resolution objects. It is very hard to detect the layer separations compared to plastic extrusion type printe
