Gizmo 3D printers use a process called DLP (Digital Light Printing) to print 3D models, layer-by-layer in a vat of photo-sensitive resin. It’s fast and very cool.

“Gizmo 3D printers use a process called DLP (Digital Light Printing) to print 3D models, layer-by-layer in a vat of photo-sensitive resin. This differs significantly from traditional 3D-printing methods like those employed my MakerBot, which essentially draws in melted ABS or PLA, working slowly to trace out each layer.

Gizmo 3D printers have two high-powered projectors that shine a focused image of one layer of the subject, which is fed from a USB-connected PC onto the surface of the resin. Wherever that image shines, the resin hardens — in about one second. Then the print base lowers a micron and the projector shines the next layer. Eventually the entire 3D-printed object is completely submerged in resin. To retrieve it, the Gizmo 3D printer raises the print platform until the object appears, still dripping with liquid resin. The effect is pretty cool.

“We display the full layer in one go,” said company CEO Kobus du Toit, “Others draw each layer.” Du Toit explained that his printers have both a standard speed and a rapid speed. At the highest speed, 3 mm per minute, the resolution is about 17 microns. If you slow the printer down, it can be as high as 57 microns.” said mashable.com

“One thing we noticed about the objects coming out of Gizmo 3D printers is that none of them were completely hardened. Apparently that’s a byproduct of the photopolymer material or resin they use.

“If you want to use it as a rapid prototype device, it won’t matter to you if it’s hard or not,” said du Toit.

Gizmo 3D’s printers, which have a little bit of a workshop look to them, are a little pricey. The company’s three DLP printers, GizMate, GizPro and GizMax, range in price from approximately $3,000 to more than $5,000.” said mashable.com
