FDM Titan	Wheel suspension

Applications

FDM prototypes made from ABS, PC, PC-ABS Blend and PPSU are mainly used as functional prototypes, due to their high thermal and mechanical strength. ABS parts can also serve as base model in the investment casting process.

Infrastructure

1 FDM Titan installation from Stratasys Inc. with maximal part dimensions of 408 x 355 x 408 mm³

Materials

ABS: for functional prototypes with good mechanical strength and chemical resistance. Available in different colours.

Polycarbonate (PC): for functional prototypes with a very high impact resistance and a thermal deflection of 125°C.

PC-ABS Blend (black): combines good mechanical and chemical resistance and can be processed, similar to ABS, with the water soluble support material (water works technology), particularly useful for complex parts.

Polyphenylsulfone (PPSU): for functional prototypes with an extremely high temperature resistance (> 200°C) and good mechanical strength.

The process

The FDM technology is an extrusion method. Comparable to stereolithography, the model is brought into position and sliced into very thin layers by means of special software. Mechanical support is generated for overhanging parts of the model. The support is removed after the building process.

The FDM Titan has the material dosed in the form of coils. This makes it easy to transport the material to the printing head, where it is melt and extruded onto the building platform.
