Z Corp (Binder Jetting)

A 3D printing process that deposits very small droplets of a liquid binder, much like an inkjet printer, to solidify a bed of powder.

Z Corp binder jetting technology allows for the creation of full color 3D models. Visual aids, architectural models, and figurines are some of the typical applications for this process. For projects where full color is key, Z Corp is a great solution.

About Z-Corp 

Z Corp uses 5 color printheads (CYMK and clear) to deposit small droplets of color binder to solidify a powder bed. The powder material, often referred to as plaster, starch, or gypsum powder, has a granular finish and is brittle out of the machine. After printing, the parts are cleaned of any powder, coated in super glue to add strength, and sprayed with a clear lacquer to protect and smooth the surface.

Binder jetting is most often used for visual display models and not for functional prototypes. Full color models can be created quickly with complex geometries using this technology. Z Corp models have been used in many applications where seeing it in color makes all the difference.

 

Design Recommendations

The brittle nature of the Z Corp material, especially before coating in super glue, requires extra design considerations to ensure that the models will hold up. Listed below are some guidelines for the minimum features that will likely survive from printing to shipping. If possible, adding thickness and supporting features will help strengthen the parts.
