Polymaker PC-PBT Filament 2.85mm, Natural Polycarbonate Filament 2.85mm PBT Blend, 1kg Cardboard Spool - Low Temperature Toughness & Good Chemical Resistance

Polymaker PB-PBT Low Temperature Toughness & Good Chemical Resistance 3D Printer Filament Key Product Features: Industrial PC Filament that need a Chamber Temperature of 【100˚C - 110˚C】 Polymaker PC-PBT is a PC/PBT polymer blend which offers good heat resistance and toughness at low temperature (-20˚C/-30˚C). Polymaker PC-PBT also features good chemical resistance. Printing Settings: Nozzle: 250˚C ~ 270˚C; Bed: 90˚C ~ 105˚C; Chamber: 90˚C ~ 100˚C; Speed: 30mm/s ~ 50mm/s; Fan: Off; Bed Surface: almost any surface with a thin coat of PVA glue or MAGIGOO PC; Drying Settings: 75˚C for 6h. Annealing settings: 90˚C for 2h. NOTE: Use a BuildTak surface, it will help hold down the print and prevent it from warping. Calibrating your printer before printing is necessary. It is recommended to use an enclosure when printing. For large part it is recommended to use a heated chamber. It is recommended to anneal the printed part right after the printing process to release the residual internal stress. How Many Kinds of PC Does Polymaker Have? The answer is 5! PolyLite PC filament offers excellent strength and heat resistance with light diffusing properties; PolyMax PC filament for extra temperature resistance and toughness and printablility; PolyMax PC-FR filament can slow/stop the spread of fire for flame retardant need; PC-ABS filament for excellent toughness and heat resistance while displaying good surface finish, PC-PBT filament for low temperature toughness and chemical resistance. looking for some strong filament?

• Industrial PC Filament: Please note that PC-PBT is an industrial PC filament that requires a chamber temperature of 100°C to 110°C.
• Strong & Heat Resistant PC Filament: Our polycarbonate filament is the strongest and most heat-resistant option available for consumer-grade 3D printers.
• Heat-Resistant & Durable: Polymaker's polycarbonate filament offers exceptional properties compared to exotic carbon fiber blends. It has minimal shrinkage upon cooling and can endure high temperatures, making it ideal for durable, functional parts, even in intense heat like a black car in the desert sun.
• Clean & Dry: The filament is carefully wound to prevent tangling, dried, and vacuum sealed with desiccant in a resealable ziplock bag. Always hold the filament tip to avoid nodes, and use the holes on the spool to help prevent this issue.
• Jam-Free & Consistent Diameter: Polymaker's polycarbonate filament is high quality, ensuring no clogs, jams, or warps. It provides excellent bed adhesion, consistent color, and dimensional accuracy for an enjoyable printing experience. Additionally, it has low odor during printing, which is a significant advantage.
