However what is PEI you ask? Well PEI (Polyetherimide), also known as known as Ultem which is a reusable and “relatively maintenance free” build surface that can be used for both ABS (with a Heated Bed) and PLA (either warmed or cold) requiring no additional adhesives such as glue or tape. PEI is extra appealing due to its “no-surface-prep” conditions, which make it convenient to work with and printing on PEI typically requires no support rafts as parts adhere directly to the surface with no issue.
However it is suggested that after each print, wipe your PEI surface down with 70-91% Isopropyl alcohol, to ensure that you remove away any grease or other residues that may have accumulated on the surface which will help increase your surface adhesion greatly.
