【Upgraded build plate】Double-sided PEO+PEI spring steel plate .One side is upgraded PEO film .PEO looks like countless diamonds on the surface,which make your eyes light up.The other side is texture PEI.It is like fine sand on a golden beach, very durable and resistant to high temperatures.It has been popular for a few years and remains a favorite among 3D printer enthusiasts.One build plate has two beautiful patterns. The bottom of the prints will leave a unique pattern. 【 Easy to Remove and use】The spring steel sheet can be bent to remove the model quickly, without the help of other tools. And the plate will return to flatness. Made of high quality spring steel plate. Flexible, removable, high strength and heat resistance, dual-side design, thicker and more durable. Easy to use, put the printing plate onto the lab printer hot bed, then the print bed levelling will automatically go on while machine powered on. (The smooth surface has a factory protective film) 【Excellent adhesion for first printing layer】The model can be firmly attached to the surface of the print bed.Easily print even for a newbie.Please let the build plate cool down before remove the model to avoid damaging the coating. 【High Resistance and Compatible Filaments】The PEO print bed surface is resistant to high temperature 150°C and textured PEI coating bed is 300℃,After our extensive testing, we recommend PET to print PLA / TPU /PETG，If you want to print other filaments, please adjust the parameters. And It is good to print PLA/PLA+/PETG/PETGCF/ABS/TPU/Nylon/PC/PA/ASA/PVA on PEI surface. 【Compatible 3D Printers】The double-sided smooth PEO+ textured PEI print bed suitable for 3D printers with 235x235mm platform size, such as suitable for Craetily K1/Ender-3 S1 /Ender-3 S1 Pro/Ender-3 V3 KE/Ender-5 S1 /K1 /Ender-3 V3 SE. Please confirm your 3D printer platform size before ordering. [Upgraded 3D printing heatingBed platform: double-sided, easy to use and good-looking] This double-sided spring steel printing platform has an upgraded PEO coating on one side, with a surface as bright as a diamond; the other side is a textured PEI coating, with a texture like gold sand. The two unique textures can leave a unique mark on the bottom of the model, which is both beautiful and practical.
