ColorJet Printing (CJP)

Colorjet printing is process is similar to the Selective Laser Sintering (SLS) process, but instead of using a laser to sinter the material, an HP ink-jet printer head deposits a liquid binder that selectively binds the powder material together. The non-bonded powder supports the part during the build. After a layer is printed, the build platform is lowered and a new layer of powder added, leveled, and the printing process is repeated. When 3D printing in color mode up to 5 printheads deposit colored binders that mix to form up to 6 million unique colors in one part.

After the build is completed, the loose supporting powder can be brushed or vacuumed away and the part removed. The remaining powder is automatically sifted and recycled back into the machine. The part can be sanded if desired and then infiltrated with numerous products such as cyanoacrylate, epoxy and other resins.

Benefits of CJP 3D Printing

  • The fasted build time of any 3D Printer
  • All unused powder is automatically recycled in the machine
  • Full color parts with up to 6 million unique colors in one part
  • Good surface finish
  • No support structures
  • Recycle all unused materials
  • Ability to build large parts – up to 20 x 15 x 9 inches

Applications for CJP 3D printing

  • Concept & ergonomic models
  • Analysis color plot models (FEA, CFD, inspection, etc)
  • Fit and form
  • Fixtures
  • Full color display models
  • Color cutaway models
  • Packaging
  • Architectural & GIS
