XYZPRINTING NOBEL SUPERFINE
Most 3D printers are basically glue-guns on the end of a three-axis rig controlled by a computer. The end of the glue-gun wobbles around smearing melted plastic onto a print surface, until after a long, long time you have a little Iron Man mask which you look at and then throw away. Digital Light Processing (or DLP) uses light from a projector to harden a special resin, pulling the print up out of a pool of goo.
DLP was too expensive and complex for the first generation of 3D printers but it’s here now! XYZ printing’s Nobel Superfine is about the same size as a regular 3D printer, but gives much better results with a smoother finish and finer detail.
DLP is still a cheaper, simpler alternative to stereolithography (SLA), which rather than a projector uses a laser to harden the resin. SLA gives the very best results but is still too expensive. Also, if you thought working with spools of plastic was a pain, just wait until you have to carefully pour resin, and then remove leftover resin with a syringe, and not get any resin on you because it’s toxic etc...
