Principle of Operation of the ThermoJet

The principle of operation of the ThermoJet is named multi-jet modeling(MJM) by the firm 3D-Systems. The MJM process belongs to the fused layer manufacturing operation group. In the print head of the thermojet there are 352 jets arranged in a line.

This piezeo-electric print head applies small drops of waxen Thermoplast on the build platform.  Due to the arrangement of the jets, they must be driven over the build platform in x direction only once per layer.
