Dual handles and dual positioning holes for precise installation and high magnetic properties at high temperatures to ensure print stability. High Temperature Resistance - The PEI Heated bed is excellent because it can withstand the numerous heat cycles that a 3D print bed goes through from print to print, it can print with most filaments, such as PLA/ABS/ASA/PETG/TPU/Nylon/PA/PC. The PEO printing surface is resistant to high temperatures of 120°C, recommand printing with PLA/TPU.
