We've been working like crazy these past few weeks and we'd like to highlight one of our new material capabilities - PPS-GF.

Polyphenylene Sulfide (PPS) with Glass Fiber (GF) is a high performance thermoplastic reinforced with glass fibers. PPS-GF exhibits excellent mechanical strength, dimensional stability, and chemical resistance while being flame retardant. This makes it ideal for applications in high thermal, chemical, and mechanical stress environments.

What is PPS-GF Filament?

PPS-GF20 is a 20% glass fiber-reinforced Polyphenylene Sulfide filament. It's a high-performance material designed for demanding applications in automotive, electronics, and industrial environments.

Advantages of PPS-GF printed parts:

• High Temperature Resistance: With a heat deflection temperature up to 235 °C after annealing, it delivers outstanding thermal stability, surpassing the temperature limits of any of our previously printable materials.

• Chemical and Solvent Resistance: PPS-GF boasts remarkable chemical resistance, a consequence of its distinctive molecular makeup. This composition enables the material to withstand acids, alkalis, and organic solvents.

• Mechanical Strength: PPS-GF offers high tensile and bending strength, excellent creep and fatigue resistance, moderate impact resistance, and high hardness.

Applications for

PPS-GF

Automotive: PPS-GF is ideal for under hood components requiring high strength and heat resistance- such as brackets, ducts, and manifolds.

Industrial: PPS-GF can be used to create high strength jigs and fixtures, and is especially suited to environments that include elevated temperatures or require the use of flame retardant materials.

Electronics: PPS-GF is suitable for connectors, sockets, and enclosures requiring excellent dimensional stability and high temperature resistance.

Comparisons

Material Properties: PPS-GF offers mechanical strength similar to or slightly better than most fiber filled nylons. However, it is much less susceptible to moisture absorption and maintains its strength at much higher temperatures after annealing. PPS-GF is one of the most chemically resistant materials available for 3D printing and meets the UL94 V0 standard for flame retardance at 1.5mm thick.

Printing Characteristics: We are seeing excellent build times and part quality with PPS-GF. It is one of our fastest printing materials and the glass fibers give part surfaces an even, matte finish. Warping is minimal and bed adhesion is excellent, both similar to PETG, allowing for large parts to be printed with relative ease. A post-print annealing is required to achieve the 235 °C HDT, typically 10 hours at 130 °C. Of all the UL94 V0 flame retardant materials we have printed with, PPS-GF prints the fastest and is the most stable.

In conclusion, PPS-GF is a reliable, high-performance material that offers significant advantages over other 3D printed thermoplastics.. The combination of outstanding properties and a wide range of applications makes it a valuable material for those seeking an effective and reliable solution for functional parts
