The ColorJet Printing (CJP) technology of the manufacturer 3D Systems – previously also known as ZPrinter – works through the layer by layer solidification of a powder material through printing on liquid binder. The surrounding powder material takes on the supporting function for complex and undercutting geometries during the printing process. After the printing process, the unprinted powder material is simply blown off in the printer, filtered and returned to the powder reservoir for the next print run. There is no subsequent removal of a supporting geometry which reduces effort as well as material consumption and thus also costs. With ZPrinters, the complete installation space can be used and components arranged quickly and easily next to each other, overlapping and stacked in the 3D Print User software and then printed out quickly and efficiently in one operational step. Models can be sealed after the printing process through infiltration. This improves colour brilliance, makes special material requirements possible and models can be processed further, e.g. with grinding, drilling, etc.
