ColorJet Printing (CJP) builds objects layer by layer in a process called additive manufacturing. This 3D printing technology involves two major components – the core and the binder. The Core™ material is a fine gypsum-based or nylon-based powder. The binder is a super-glue like liquid mixed with the CMYK or CMY colors. The powder is spread in a thin layer over the build platform. After each layer is spread, color binder is selectively jetted from inkjet print heads solidifying and binding the particles together. Another layer of Core™ is spread over the previous layer and the process repeats to create a full-color, three-dimensional objet. See also Powder Bed Printing.
