Product Description: 
PEI (Polyetherimide) sheets provide a 3D printing build surface that requires NO tape, slurry, or adhesive. ABS and PLA both stick extremely well to the surface, and printing on PEI requires no support rafts as parts adhere directly to the surface with no issue. 

How to Use: 
Please remove both sides of the teal colored protective film before using. Cut the PEI sheet to size by scoring with a hobby knife. There are two ways to attaching the PEI to your print bed. The first way is to just clamp the sheet to the print bed using binder clips. We find that 2 on each side works great. The second way- get 3M 468MP Transfer Tape and use it to stick the PEI to the print bed.It helps to wipe the surface down with isopropyl alcohol, methyl alcohol, or soap in between prints. This will ensure the PEI is clean, and help adhesion. Light sanding with 5000 grit paper will also give the PEI sheet more life.
