PPS-GF 3D printing
High-temperature resistant components made of
glass fiber reinforced polyphenylene sulfide
High-temperature resistant components made of glass fiber reinforced polyphenylene sulfide
Polyphenylene sulfide with glass fiber reinforcement (PPS-GF20) is among the most thermally and chemically resistant printable high-performance polymers. Malping processes PPS-GF20 using both FFF (filament) and FGF/granule printing—depending on component size and cost target. The result: functional components that retain their shape even under continuous heat stress, aggressive media, and mechanical loads.

PPS-GF20 (Polymaker Fiberon PPS-GF20) is a semi-crystalline, high-performance polymer with 20% glass fiber content. Compared to pure PPS, the glass fibers significantly increase stiffness, improve dimensional stability, and enhance heat resistance. The material is insoluble in all known solvents below 200 °C and meets UL94-V0 at a wall thickness of 1.5 mm.
Note: Tempering for maximum performance
Through targeted annealing after printing (approx. 2–4 hours at 130 °C), the PPS-GF20 recrystallizes and achieves its full thermal and chemical properties. Malping performs annealing as a standard procedure and supplies only annealed components.

Typical application areas for PPS-GF
Automobile & Engine Compartment
Fuel line brackets, housings in the engine compartment, sensor housings, fuel system components: PPS-GF20 remains dimensionally stable during continuous operation up to 230 °C and withstands fuel, oil and aggressive cleaning agents.
Electrical Engineering & Electronics
Connectors, insulators, switchgear enclosures, RF components: UL94-V0 certification and high dielectric strength (6.05 kV/mm) make PPS-GF20 the first choice where fire protection and electrical insulation come together.
Chemical plants & pumps
Pump housing, valve body, seal carrier: the almost universal chemical resistance to acids, alkalis, solvents and the low water absorption make PPS-GF the ideal material for media systems.
Mechanical engineering & fixture construction
Functional components, gauges, and brackets subject to thermal stress: the high stiffness (flexural modulus > 4 GPa) and good creep resistance replace metallic components while significantly reducing weight.
Aerospace
Mounting brackets, air ducts, engine compartment components: the favorable ratio of weight, temperature resistance and chemical robustness covers the requirements catalog for structural secondary parts.
Frequently asked questions about
PPS-GF20 3D printing
What is the difference between PPS and PPS-GF?
Pure PPS has good basic properties, but comparatively low stiffness. PPS-GF20 contains 20% glass fibers, which increase the flexural modulus to over 4 GPa, improve heat resistance, and enhance dimensional stability. And all this with only a minimal reduction in impact strength.
Does PPS-GF need to be tempered after printing?
Yes. Like all semi-crystalline high-performance polymers, PPS-GF20 only achieves its full mechanical, thermal, and chemical properties after heat treatment. Malping tempers all PPS-GF components as standard practice.
How does pellet printing differ from normal FFF printing in PPS-GF?
In the FGF process, the material is fed directly as granules and melted in the print head — without the expensive intermediate filament step. This saves considerable material costs for large components and enables significantly larger build volumes (up to 510×510×400 mm on the ExAM 510).
For what minimum size does Malping recommend pellet printing?
Pellet printing becomes economically viable for component volumes of approximately 300 cm³ and above. Below this volume, the advantages of FFF (higher precision, no setup time) outweigh the disadvantages.
Can PPS-GF be CNC machined?
Yes. Malping offers CNC post-processing as an optional service, achieving tolerances of up to ±0.05 mm on functional surfaces. Bores, fits, and sealing surfaces, in particular, benefit from this post-processing.
Which file formats are accepted?
STEP file format (.step / .stp) is preferred. Alternatively, STL is acceptable. For drawings only, without 3D data, we offer design services.
Does Malping deliver to my country?
Malping ships worldwide. Please be aware of possible restrictions due to embargoes or dual-use regulations.
