PPS Filament


PPS (polyphenylene sulfide) is a heat-resistant and high-performance plastic for 3D printing. This semi-crystalline plastic is characterized by its special robustness and a very high temperature resistance. It keeps its mechanical characteristics, such as dimensional stability even during long-term use at high temperatures of more than 100 degrees. Its chemical resistance to almost all solvents, many acids and alkalis is also impressive. In addition, polyphenylene sulfides are highly impervious to liquids and gases and are characterized by their low moisture absorption and low creep tendency.

Due to its high electrical dielectric strength, the PPS filament is ideal as an insulator. This outstanding properties of PPS allow a very versatile use of printed components. Particularly in the electronic and automotive industry molded components are manufactured by additive manufacturing using PPS, that have to withstand the highest mechanical, electrical, thermal and chemical stresses.

Processing parameters:

Extrusion temperature:335 °C
Print bed temperature:120 °C
Print bed material:Kapton foil

Since PPS is a semi-crystalline plastic and both the printing and the glass transition temperature (90 ° C) are very high, a enclosed and heated printing chamber with active temperature control is essential for a stable manufacturing process.

When printing PPS tension build up inside the component, even with a heated printing chamber, that’s why the adhesion of the component to the printing platform is an important factor. It has also been shown that these tension can become so strong that thin printing platforms, even made out of carbon fiber or aluminum, deform during printing, so a very high dimensional stability of the print bed is mandatory.

This plastic can be machined and screwed directly or by adding a nut insert during the printing. Due to the chemical resistance, glued connections with solvent-based adhesives are not possible, however connections using two-component epoxy resin or polyurethane adhesives are possible. [1]

In order to paint PPS components, the surface must be treated, for example by flame treatment or by a polyurethane-based primer.[1]

Solubility / resistance

PPS is dimensionally stable up to 150°C and is also resistant to almost all solvents, many acids and alkalis. Due to the great variety of this chemical substances, the resistance of the material must be clarified by case when required.


PPS is the right choice for permanent high-temperature applications under high mechanical stress, for example as a 3D-printed laminated moulds for multiple use in autoclaves at high temperatures and pressures.

Thanks to the outstanding chemical resistance, PPS can be sterilized without any problems, which makes it ideal for applications in the medical field.

PPS is inherently flame-resistant and reaches a classification of V0 according to UL 94 by a thickness of 0.4mm (extinguishing the flame after 10s, max. 30s afterglow, no flaming droplets)
