However, its the company’s Nobel 1.0, debuting at CES 2015, that stands out among the pack. Whereas most 3D printers rely on fused filament fabrication to melt plastic and create 3D objects, the Nobel 1.0 is one of the few that uses Stereolithography Apparatus (SLA). The printing method utilizes a liquid ultraviolet-curable photopolymer — called resin — in conjunction with an ultraviolet laser to craft 3D objects, slice by slice. The laser traces a cross section of the desired object’s pattern on the liquid, which then gradually cures and hardens when exposed to the ultraviolet laser. Then, it’s simply a matter of wash, rinse, and repeat until the object is fully formed.
