Rapid prototyping for 3D prototypes and visual models
Multi jet modelling
The technology
In the multi jet modelling process, a product is built up of thin layers of wax. The mechanical properties of the model are less important, the easy formation of complex shapes is more important. Models generated by MJM are used mainly to help designers in visualising complex shapes.
Layer by layer is plotted on a wax plotter, under computer control, on the basis of the usual 3D CAD description. The plotting head has a large number (up to 100) individual wax jets. It is moved from left to right and back to "print" narrow strips. The wax is deposited in a low-strength raster-like structure. Where necessary, a supporting structure can be added - in the same material - which is removed easily once the model is finished.
