UBJ

CIREX can also produce prototypes using Universal Binder Jetting, or UBJ. This is primarily interesting for larger numbers and/or larger sizes of products. 3D models produced with this technique are made from PMMA powder and a binder.

A very thin layer of PMMA powder is spread across the build platform, after which the print head moves over the platform and selectively applies the binder. The 3D model is created where the binder is applied. The binder reacts with the powder and solidifies, thus creating a layer. By printing several layers on top of each other, the plastic 3D model is produced.

After the 3D model is printed, it can go through the normal CIREX process. In this process, in addition to melting the wax, the plastic must also be burnt out.

ADVANTAGES

One of the advantages of UBJ is that the 3D models made from PMMA are very accurate, as this technique prints in very thin layers. Due to these thin layers, the layer seams are minimally visible. As CIREX collaborates with various partners to produce the PMMA models, we can guarantee short delivery times, even for large batches.
