Spectrum PPS AM230 filament is a high-performance technical filament based on the engineering polymer PPS (polyphenylene sulfide), designed for the most demanding industrial applications requiring extreme thermal, chemical and mechanical resistance.

Key properties

PPS AM230 belongs to the top-tier high-temperature polymers. It excels in exceptional thermal stability - the Vicat softening point reaches 236 °C and HDT (0.45 MN/m²) is 129 °C. Even under continuous load at temperatures above 100 °C, it retains its stiffness, strength and creep resistance. The filament is practically insoluble in any known solvent, including concentrated acids and bases. Also characteristic is its inherent non-flammability without the need for flame-retardant additives. Thanks to its high dielectric strength, PPS is an ideal electrical insulator. A notable feature is its excellent adhesion to silicone, which enables the production of airtight assemblies with a perfect bond between components.

Printing parameters

Who is Spectrum PPS AM230 filament suitable for

PPS AM230 is intended for professional users and industrial applications where common filaments such as PLA, PETG or ABS are not sufficient. Typical areas of use include electronics and the automotive industry, where parts must withstand high mechanical, electrical, thermal and chemical stress. The material is suitable for printing live parts of devices and machines, precision components, parts exposed to concentrated acids, bases and solvents, as well as manufacturing tools and jigs. Printing requires a high-temperature printer with an all-metal hotend capable of reaching at least 330 °C and an actively heated enclosed chamber.

Printing tips

• Always thoroughly dry the filament before printing at 90 °C for 6-8 hours - PPS is hygroscopic.
• Use a printer with an all-metal hotend and a hardened nozzle (steel, ruby, tungsten).
• An actively heated chamber (60-80 °C) is essential for successful printing - it reduces the risk of delamination and warping.
• After printing is complete, leave the model in the warm chamber and let it cool down gradually - this will prevent cracks caused by thermal stress, especially on geometrically complex models.
• Turn off the model cooling fan - PPS requires stable thermal conditions for perfect layer bonding.
• For better adhesion to the print bed, use specialized glues or a PEI sheet.
• Print in a well-ventilated area; fumes may be generated at high temperatures.
• Lower print speeds (30-50 mm/s) improve interlayer adhesion and print accuracy.
