FDM

Fused Deposition Modeling (FDM) creates tough parts that are ideal for functional applications.

FDM works on an "additive" principle by laying down material in layers.

A plastic filament is unwound from a coil and fed to an extrusion nozzle. The nozzle is heated to melt the material while the machine traces out the cross-section of each layer, laying down a continuous stream of molten material.

The platform is lowered after each layer. The model is built up from layers as the plastic hardens immediately after extrusion from the nozzle.

The materials available for use in the FDM process include:

ABS - for functional prototypes with good mechanical strength and chemical resistance. Available in different colors.
Polycarbonate (PC) - for functional prototypes with a very high impact resistance and a thermal deflection of 125°C.
Polyphenylsulfone (PPSU) - for functional prototypes with an extremely high temperature resistance (> 200°C) and good mechanical strength.
