This double-sided textured spring steel sheet provides an ideal printing surface for your 3D printer. Crafted from durable PEI material, it features a textured coating on both sides that allows objects to easily adhere while printing but removes just as easily after, without damaging the surface. At 257x257mm, it is the perfect size to fit build plates on popular desktop 3D printers like the Bambu Lab X1 and P1 series. Its flexible yet resilient design conforms smoothly to heating plates without warping or degrading over many print cycles. An affordable upgrade for any FDM printer, this PEI spring steel sheet promises strong, blemish-free prints thanks to its non-stick, heat-resistant properties. Its double-sided usage maximizes the lifespan of this premium build surface.
