3D printing materials provider Polymaker has introduced Fiberon PPS-GF20, a glass fiber-reinforced Polyphenylene Sulphide (PPS) filament.
Priced at $65.99, this material targets industrial applications that demand a combination of thermal stability, chemical resistance, mechanical strength, and electrical insulation. Designed for high-speed printing up to 250 mm/s, PPS-GF20 maintains consistent Z-axis strength with minimal warping and is compatible with hardened steel nozzles.
Its low moisture absorption rate of 0.11% (measured at 70% RH and 23°C) ensures reliable performance even in humid environments. Supplied in vacuum-sealed packaging, the filament is also compatible with Bambu Lab AMS systems, making it easy to store and handle.
Polymaker’s growing filament portfolio
A few days ago, the materials manufacturer launched Fiberon PA612-ESD, a nylon 612 filament reinforced with carbon nanotubes and carbon fibers to deliver both electrostatic discharge (ESD) protection and mechanical strength for industrial use.
Developed for applications like electronics housings and jigs in static-sensitive environments, the material offers a heat deflection temperature of 157°C at 0.45 MPa and maintains structural stability under thermal stress. It achieves up to 84.3 MPa tensile strength (X-Y, dry) and a Young’s modulus of 4293.7 MPa, with performance varying in humid conditions. The filament prints without a heated chamber, supports nylon-based breakaway supports, and benefits from hardened nozzles.
In 2023, Polymaker introduced PolySonic PLA and PolySonic PLA PRO, two filaments engineered for the demands of high-speed FDM 3D printing. Formulated to print at speeds exceeding 300 mm/s, PolySonic PLA focuses on extrusion efficiency, while the PRO variant adds impact modifiers for enhanced ductility and stiffness, comparable to ABS and exceeding ASA and PETG.
Both materials aim to improve extrusion flow, shape consistency, and part strength. Internal testing shows a 40% increase in volumetric flow and only a 6% drop in mechanical strength at high speeds, compared to a 24% reduction in standard PLA.
The new Polymaker PPS-GF20 filament
Reinforced with 20% glass fibers, PPS-GF20 offers a Heat Deflection Temperature (HDT) exceeding 230°C, which can rise to 236.3°C at 0.45 MPa after annealing, while delivering a Young’s modulus of up to 4552 MPa and a bending strength of 102 MPa in the XY direction.
This combination of properties ensures excellent dimensional stability under both heat and mechanical load, making it well-suited for components that must perform reliably in elevated temperatures or harsh operating environments.
In addition to its thermal and mechanical performance, PPS-GF20 provides strong electrical insulation, with a dielectric strength of 6.05 kV/mm and a low dielectric constant of 2.71 at 1 MHz, allowing it to be used effectively in applications such as electronic housings, ADAS sensor enclosures, and 5G base station components. Because the filament is reinforced with glass fibers rather than carbon, it avoids signal interference and supports uninterrupted transmission in sensitive electronic systems.
The material is also UL94 V0 rated at 1.5 mm and exhibits resistance to a wide range of chemicals, including acids, bases, oils, and solvents, which further extends its suitability to components used in chemical laboratories, factory environments, and automotive systems.
Post-processing can be enhanced through high-temperature annealing, which improves isotropy in mechanical properties, although minor visual discoloration may occur. For more complex designs, the filament is compatible with PolySupport for PA12, enabling easy manual support removal and simplifying the finishing process.
Available in a neutral gray finish chosen to reduce heat absorption and improve post-processing flexibility, PPS-GF20 offers a balanced combination of thermal, mechanical, electrical, and chemical performance tailored for high-performance, industrial-grade 3D printing applications.
