Neptune3Pro/plus/max supports printing with PLA, ABS, PETG and TPU95A filaments with a diameter of 1.75mm. In theory, filaments with printing temperatures between 180°C and 260°C are compatible, but considering the characteristics of certain materials, problems such as drawing, warping, and cracking may occur. Some special materials (such as PLA carbon fiber and marble materials) may cause the nozzle to wear quickly and the nozzle is easy to clog, so it is recommended that PLA or PLA+ be the first choice. For materials with high temperature and environmental temperature requirements (such as ABS and ASA), you need to put the printer into an insulating box for printing.
