1、PEY and PEI Surfaces: Double sided printing build plate, PEY film with small patterns that reflect different colors at different angles, and the other side is PEI spraying, which is convenient and practical. 2、Applicable Models: The size of the 3D printing hot bed is 235 x 235mm, suitable for Ender 3 S1 Pro, for Ender 3 S1, for Ender 3 V2 Neo, for Ender 3 V2, for Ender 5, for Ender 5 S1, for Ender 5 Pro, for CP‑01, for CR‑20. 3、Convenient to Clean: The spring steel build plate has 2 pressure edges, which you can print multiple times on PEY or PEI. If the PEY surface is dirty, just wipe it with a wet tissue and then dry it with a dry tissue. 4、Good Performance: PEY has better adhesion than smooth PEI, PET or PEO, increasing its adsorption on the printing model. After bending, it can be restored to a flat state without damaging the model. 5、Applicable Consumables: The PEY surface is suitable for printing PLA, TPU, PETG (temperature recommendation: 50‑70℃, ≤90℃), the PEI surface is suitable for PLA, PLA CF, PETG, PC, ABS, TPU, nylon, etc.
