Nearing the end of the build process the first chamber runs a cursory powder removal cycle that removes the bulk of the excess powder. The innards of the printer are divided into two chambers one for building and one for fine-powder removal. The results can include graded color fades, intricate patterns, and near lifelike color renditions. Add up all these layers, dust off any extra powder, and you get a full-color 3D model. When the shape has been etched into the powder, the print bed lowers down ushering in a fresh layer of powder spread thanks to a roller for the process to repeat itself. The main upside of the technology is a near limitless use of color because the inkjet selectively colors the binder from a range of 180,000 individual shades before applying it to the powder. The basic tenet of the process involves a print head – very similar to that found in traditional inkjet printers – selectively laying down a liquid binding material on a thin layer of powder causing it to solidify into a specific shape and design. Rather than relying on Fused Deposition Modelling, the Zcorp Z450 is based on a patented additive manufacturing technology known as 3DP, ZPrinting, or ColorJet Printing depending on who you ask. Visually, the ZCorp Z450 isn’t the most appealing and is very much a product of tech production of the early 2010s with a rather uninspiring grey scheme covering the entire unit only interrupted by a questionably stylish orange near the control panel.
