SUNLU PC 3D Printer Filament 1.75mm 1KG（Natural White）

Product Details

• ①【Superior Strength & Impact Resistance】- SUNLU PC Filament is a professional-grade polycarbonate filament engineered for demanding applications. Featuring exceptional toughness and impact resistance up to 35 kJ/m², it produces durable functional parts that resist cracking, breaking, and deformation, making it ideal for engineering prototypes, industrial tools, and high-performance components.
• ②【High-Temperature Reusable Spool】- Designed for high-temperature printing, SUNLU PC Filament comes with a reusable spool that withstands temperatures up to 101°C (214°F) without deformation. The heat-resistant spool maintains excellent stability throughout long print jobs, ensuring reliable feeding and consistent printing performance.
• ③【Optimized for Professional Printing】- For the best printing performance, we recommend:Nozzle Temperature: 260–280°C, Bed Temperature (with Glue): 100–110°C, Print Speed: ≤150 mm/s.
• ④ 【Built for Engineering Applications】- Combining high toughness, superior strength, excellent heat resistance, and dimensional stability, SUNLU Polycarbonate Filament is perfect for demanding applications including automotive components, electronic enclosures, manufacturing fixtures, mechanical parts, and other functional prototypes that require long-lasting performance.
• ⑤【Warp-Free & Precision Printing】- Engineered with low shrinkage and exceptional dimensional accuracy of ±0.02 mm, SUNLU PC Filament minimizes warping and cracking while delivering reliable layer bonding. Each spool is neatly wound for smooth feeding and clog-free printing, ensuring stable performance and broad compatibility with most FDM 3D printers.

Printing SUNLU PC

SUNLU PC in White runs on the PC profile below, and this listing is a 1kg spool. PC is best suited to high-strength, heat-resistant engineering parts; PC-ABS/PC-GF/PC-CF blends print easier than pure PC at some cost to peak performance. Brands and even individual spools vary, so treat these as starting points and run a quick temperature tower to lock in the sweet spot for your printer.

Ranges checked against Bambu Lab, Prusament and Polymaker data. Heat resistance is the heat deflection temperature (HDT). Read our Polycarbonate (PC) filament guide for bed adhesion, drying, troubleshooting, and material-specific tips.

Nozzle Compatibility

This is an unfilled plastic, so it is not abrasive: a brass nozzle works and lasts, and so does hardened steel. With hardened steel, print about 5 to 10°C hotter.
