MADE IN THE USA: Single 1mm thick sheet installs quickly on top of existing flat build platforms (e.g. borosilicate glass) using the 3M 468MP adhesive transfer tape. ABS and PLA filaments (along with many other materials) print directly on to PEI surface without the need for additional adhesives, tapes, or slurry. REMOVE FILM FROM BOTH SIDES BEFORE USING: Blue protective film guards against scratches during shipping and handling. Reuse for multiple prints, just wipe down with isopropyl alcohol between prints for best results Includes: 1x PEI sheet, 1x full size 3M 468MP adhesive transfer tape
