BuildTak Polyetherimide (PEI) build surfaces are made from premium Ultem 1000 PEI equipped with the no-cleanup BuildTak Original adhesive. A comparable alternative to the BuildTak Original 3d printing surface, BuildTak PEI exhibits slightly different adhesion and release properties which vary depending on the material being printed.
In general, BuildTak PEI offers easier release of finished prints while BuildTak Original offers a stronger hold during printing. Paired with our Complete BuildTak FlexPlate System, you can keep multiple FlexPlates on-hand to easily swap out between the BuildTak Original and BuildTak PEI print surfaces, depending on the material being printed. (For example, Polycarbonate requires BuildTak’s extra-strong hold to finish prints successfully, while PEI should be used for PETG because of its easier release.)
BuildTak PEI and BuildTak Original are both 0.010″ so no need to re-level when swapping!
