Printing Setting: Nozzle Temp: 220-280, bed Temp: 80-100, printing speed:30-70mm/s, dimensional accuracy +/- 0.04 mm. High strength and Durability: Suitable for manufacturing durable auto parts, mechanical parts, and protective shells. Nylon filament is an excellent choice for engineering materials. PVA glue is always required for better adhesion. Wide compatibility: Compatible with most 3D printers that use 1.75mm filament in the market, including SainSmart Creality, MK3, Monprice FlashForge, QIDI, etc. SainSmart 3D Printer Filament provides quality PLA/ PVA/ PA/ PETG/ TPU/ PA-CF 3D filament.
