Printing
The
additive fabrication technique of inkjet printing is based on the 2D printer
technique of using a jet to deposit tiny drops of ink onto paper. In the
additive process, the ink is replaced with thermoplastic and wax materials,
which are held in a melted state. When printed, liquid drops of these materials
instantly cool and solidify to form a layer of the part. For this reason, the
process if often referred to as thermal phase change inkjet printing. Inkjet
printing offers the advantages of excellent accuracy and surface finishes.
However, the limitations include slow build speeds, few material options, and
fragile parts. As a result, the most common application of inkjet printing is
prototypes used for form and fit testing. Other applications include jewelry,
medical devices, and high-precisions products. Several manufactures have
developed different inkjet printing devices that use the basic technique
described above. Inkjet printers from Solid scape Inc., such as the Model Maker
(MM), use a single jet for the build material and another jet for support
material. 3D Systems has implemented their MultiJet Moldeling (MJM) technology
into their ThermoJet Modeler machines that utilize several hundred nozzles to enable
faster build times.

(thermoplastic) and
support material (wax) being held in a melted state inside two heated
reservoirs. These materials are each fed to an inkjet print head which moves in
the X-Y plane and shoots tiny droplets to the required locations to form one
layer of the part. Both the build material and support material instantly cool
and solidify. After a layer has been completed, a milling head moves across the
layer to smooth the surface. The particles resulting from this cutting
operation are vacuumed away by the particle collector. The elevator then lowers
the build platform and part so that the next layer can be built. After this
process is repeated for each layer and the part is complete, the part can be
removed and the wax support material can be melted away.
