PEI (Polyetherimide) , also known as Ultem, is a reusable, relatively maintenance free, perfect build surface for both
ABS (with a Heated bed) and PLA (hot or cold), other materials such as Metal, Wood, ABS+ and many
others also works just fine. PEI sheet is appealing due to its “no-surface-prep” conditions, which make it convenient to work with.
Additionally, printing on PEI sheet requires no support rafts as parts adhere directly to the surface with no issue.
This PEI sheet is Pre-applied with 3M 468MP Adhesive Transfer Tape for your convenience
PEI Stick very well to certain material such as PC and PETG ( Not recommend PC on PEI surface or use Glue Stick on PEI.)
Material: PEI/ULTEM 1000
Thickness: 0.5 mm (0.02″)
HOW TO USE:
This PEI sheet is specially made for Flashforge Creator Pro or Makerbot Replicator 2X or any same size heated build plate printer . This PEI sheet is Pre-applied with 3M 468MP Adhesive Transfer Tape for your convenience. All you need is clean your 3D printer bed, so it is free of dust. Then peel off one side of 3M 468MP Adhesive and slowly and evenly use a flat card to sweep the PEI sheets to the build bed. Make sure there is no bubble ( it is very rare it will has a bubble ), also keeping in mind that 3M 468MP is a very sticky tape that is prone to clumping.
Sanding the PEI is not required or necessary, but sanding with a fine grid sandpaper will help the part stick better to the PEI build surface.
Once you have laminated your PEI sheet onto your print bed, simply re-level your print bed and print away. Parts should come free from the surface with almost no issue at all. PLA does not require heat, but turning the heated bed up to 60 °C work best with PEI.
PEI sheet work perfectly well with ABS for delta printer with 100-110 °C. After the print is done, just let the PEI sheet cool down and then gently you can just “pop” the finish print off the plate easily.
Before each print, wipe your PEI sheet surface with 70-91% Isopropyl alcohol to ensure that you wipe away any grease or other residues that may have accumulated on the surface. This will help increase your surface adhesion greatly.
