CJP Banner

About Sandstone Material

Color Jet 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 object.

The main achievements of professional 3D printers using gypsum are high speed of print construction and decent surface quality of the object. In prototyping, the technology is valued because of the rapid production of layouts that do not require additional processing or coloring. The appearance of the printed samples is almost indistinguishable from the original source, since the equipment accurately copies the geometry, hue, and texture of the product.

Think3D has been a great partner for us in supplying COVID-19 test cartridges on-time despite the pandemic challenges. When we came up with a new requirement needing a workforce of more than 25 people, think3D took up the challenge and arranged the workforce within 2 days. I highly recommend think3D for any manufacturing needs.

As a professor doing research on new materials, I needed a strong industry partner to assist us. think3D perfectly fit that bill. think3D team is highly knowledgeable on all manufacturing technologies and the team is very prompt in responding to all our requests. My research has been very successful, thanks to think3D team.

We found issue with one part at the time of assembly and needed a quick replacement. think3D team has quickly responded to our request, redesigned the part and printed it using metal 3D Printing and delivered in 3 days time. The part came out really well and the design was better than that of the actual one.
