BuildTak PEI Surface 220 x 220mm PEI220X220

The BuildTak polyetherimide (PEI) printing films are manufactured here in the USA to ensure consistent quality and composition. They are made of high quality Ultem 1000 PEI, which is equipped with the non-cleaning BuildTak original adhesive. BuildTak PEI is a comparable alternative to the BuildTak Original 3D printing surface and has slightly different adhesion and release properties that vary depending on the material being printed. In general, BuildTak PEI offers easier release of finished prints, while BuildTak Original offers stronger grip when printing. Combined with our complete BuildTak FlexPlate system, you can have multiple FlexPlates on hand to easily switch between the BuildTak Original and BuildTak PEI printing surfaces depending on the material to be printed. (For example, polycarbonate requires BuildTak's extra strong hold to successfully complete prints, while PEI should be used for PETG because of its easier release.) BuildTak PEI and BuildTak Original are both 0.010 inches thick so there is no need to re-level when swapping!
