1、DOUBLE SIDED PRINTING: One side is sprayed with PEI powder, which has high adhesion and wear resistance, while the other side has PEO rhombus texture, resulting in a glossy and flat bottom of the printed model. 2、SPRING STEEL: The 3D printer build plate uses excellent spring steel, which has high flatness, high strength, and good elasticity. After printing, simply bend gently to easily demold the model. 3、SAFE OPERATION: The PEI layer can withstand a temperature of 260℃ and no deformation, the PEO surface can work at a high temp of 80℃. The dual handle prevents burns, the locating hole is convenient for installation and use. 4、GOOD FLEXIBILITY: The PEI and PEO spring steel plate has good flexibility. Once the surface is cooled, the model can be easily removed by hand or the build plate can be bent to remove it without deformation. 5、APPLICABLE RANGE: This printing board has a size of 310x315mm and is suitable for Ender 3 V3 Plus 3D printer. It is compatible with PLA, ABS, ASA, PETG, TPU, PC, PA, and other materials.
