Feature:1. UPGRADED DOUBLE SIDED PRINTING: Double sided PEO and PEI spring plate, one side is smooth diamond printing surface, upgraded PEO film. The other side is PEI frosted surface, which makes the surface of the frosted sticker show a unique frosted touch, and the adhesion with the model and the print is stronger, and will not deform2. HIGH STRENGTH AND IMPACT RESISTANT: Double sided PEO and PEI spring steel plate has extremely high strength, can withstand large weight and pressure, while having good wear resistance and impact resistance3. HIGH TEMPERATURE RESISTANT: Double sided PEO and PEI spring steel plate has high temperature resistance, can work stably in high temperature environment, will not be deformed or broken due to high temperature4. EASY TO PROCESS AND RELEASE: The double sided PEO and PEI spring plate has good processing properties and is suitable for a variety of complex application scenarios, such as the PEO printing plate surface can print PLA, TPU and PETG. If you print other materials, you will need glue. PEI panel can print most filaments, such as PLA, ABS, PETG, TPU, Nylon. Simply bend the PEO PEI by hand, and the model can be easily released without the use of other tools5. COMPATIBLE WITH 3D PRINTERS: The double sided smooth PEO and textured PEI printing bed is suitable for 3D printers with platform dimension of 220x220mm, such as for Anet A6, A8, ET4 series, for LONGER LK4, for WANHAO 13, for prusa i3, etc., or other hot bed size 220x220mm modelsSpecification:Item Type: 3D Print Build PlateMaterial: Spring steelProduct Size: Approx. 220 x 220mm / 8.66 x 8.66in.Package List:1 x 3D Print Build PlateNote:1. Under normal circumstances, it is easy to remove the model from the plate, if not, please do not force, you can put in the refrigerator for a few minutes, and then try again.2. PEO and PEI must be used together with the magnetic holder.
