Overview: How CJP 3D printing works?

[hr] [/spb_text_block] [spb_text_block pb_margin_bottom=”no” pb_border_bottom=”no” width=”1/1″ el_position=”first last”]

The Basics Of CJP 3D Printing

ColorJet Printing (CJP) is an additive manufacturing technology which involves two major components – core and binder. The Core™ material is spread in thin layers over the build platform with a roller.

After each layer is spread, color binder is selectively jetted from inkjet print heads over the core layer, which causes the core to solidify. The build platform lowers with every subsequent layer which is spread and printed, resulting in a full-color three-dimensional model.

Objects printed in full-color sandstone can withstand temperatures of up to 60°C (140°F) – beyond that the object’s properties can be significantly altered. Full-color sandstone objects are also somewhat fragile (comparable to a porcelaine), so it is important to handle them with caution.

The prints have a gritty surface and are relatively porous. It is thus important to avoid direct contact with water as it could result in discoloration or running of the colors.

Benefits Of CJP

Full-color sandstone is one of the only 2 materials(the other is Polyjet Fullcolor Polymer) which can 3D print in full color. This makes it the perfect material for figurines, avatars, 3D-scans, or anything that require full color, it’s especially ideal for the following purposes:

  • Full-color concept models
  • Architectural models
  • Demonstration models
  • Highly complex geometries
  • Quick production times

The raw finish option with the quickest turnaround.

The object is only cleaned of excess powder. This finishing leaves a grainy, rough surface.
