It sits a step above PC, PA, or POM: Forward AM rates it for peaks up to 220 °C and continuous service at 180 °C, with self-extinguishing UL 94 V-0 certification and autoclave sterilization compatibility. Before purchasing, make sure your printer can actually handle what this filament demands — it is not a desktop printer material.\u003c\/p\u003e\n\u003ch3\u003eKey Specs\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMaterial: polyphenylsulfone (PPSU), natural amber color — described as yellow\/brown in the datasheet.\u003c\/li\u003e\n\u003cli\u003eNozzle: 390–410 °C, bed: 220 °C, actively heated enclosure: 170–210 °C.\u003c\/li\u003e\n\u003cli\u003eHDT of 215 °C at 0.45 MPa and glass transition temperature of 222 °C (TDS v2.0).\u003c\/li\u003e\n\u003cli\u003eUL 94 V-0 rated at both 1.5 mm and 3.0 mm thickness, per the manufacturer.\u003c\/li\u003e\n\u003cli\u003e750 g spool, 1.75 mm diameter.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eCan My Printer Handle This?\u003c\/h3\u003e\n\u003cp\u003eAlmost certainly not, if you're using a desktop printer. Forward AM requires a nozzle temperature of 390–410 °C, a bed temperature of 220 °C, and an actively heated enclosure running at 170–210 °C. A standard enclosed printer won't reach those numbers — having a shell around the print area isn't enough; the chamber needs real active heating. This is a material for high-temperature industrial machines, and Forward AM only publishes a print profile for Intamsys printers.

It is also recommended as a support material for PEI-based filaments such as ULTEM 9085. The flammability data includes passed FAR 25.853 testing (aerospace) at the specified thicknesses, as well as compliance with railway standard EN 45545-2.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eProperty\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNozzle Temperature\u003c\/td\u003e\n\u003ctd\u003e390–410 °C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBed Temperature\u003c\/td\u003e\n\u003ctd\u003e220 °C (TDS); 200–220 °C per product page\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEnclosure Temperature\u003c\/td\u003e\n\u003ctd\u003e170–210 °C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBuild Surface\u003c\/td\u003e\n\u003ctd\u003eGlass\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNozzle Size\u003c\/td\u003e\n\u003ctd\u003e≥ 0.4 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePrint Speed\u003c\/td\u003e\n\u003ctd\u003e25–100 mm\/s\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePrinted Part Density\u003c\/td\u003e\n\u003ctd\u003e1272 kg\/m³\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHDT at 1.8 \/ 0.45 MPa\u003c\/td\u003e\n\u003ctd\u003e211 °C \/ 215 °C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTensile Strength XY \/ ZX\u003c\/td\u003e\n\u003ctd\u003e74.5 MPa \/ 49.0 MPa\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFlexural Modulus XY \/ ZX\u003c\/td\u003e\n\u003ctd\u003e1940 MPa \/ 1700 MPa\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFlammability Rating\u003c\/td\u003e\n\u003ctd\u003eUL 94 V-0 at 1.5 mm and 3.0 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGlow Wire (GWEPT)\u003c\/td\u003e\n\u003ctd\u003e960 °C at 1.5 mm and 3.0 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch3\u003ePrinting Tips\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAlways dry before printing: the manufacturer specifies a vacuum dryer at 125 °C for 8 hours.\u003c\/li\u003e\n\u003cli\u003eKeep the spool in a sealed container during printing.
