Gianluca Pugliese is an artist who uses a variety of materials and 3D technology to create his pieces, but of late, his principal material has been light. Working with a company which has been manufacturing 3D printers in Italy for the last couple of years, the WASP Project, Pugliese is using long exposure times in a dark environment to photographically capture the movement of a light source attached to a 3D printer, and he calls it “CNC light painting.” Pugliese began refining his technique after discovering an open source project on the web which allowed him to build his own Delta-based printer, and he says that was the turning point. His results improved dramatically, to the point where one of his projects was included in the Venice Biennale. You can read the whole story here: http://3dprint.com/90082/wasp-and-gi...int-with-light
