How to prepare your PEI Sheet for 3D printing:


1) Clean your surface (glass or flex sheet) with IPA (>90%)


2) Apply your PEI sheet like you would a screen protector. Slightly peel off the adhesive backing, align, then slowly remove the backing as you progress.

Tip: Take you time and go slow! 


3) Wetsand your sheet with 400 grit-600 grit- 1200 grit sandpaper.

  1. Spray some water onto the sheet, sand in one direction, rotate the sheet by 90 degrees then sand in the same direction.
  2. Wipe the sheet with a paper towel.
  3. Spray some water and proceed with the next desired grit.
  4. Once you're done, spray some >90% IPA, I prefer using 99%. Wipe and heat the bed to 50 for 5 mins to dry the IPA. 
  5. Spray some IPA onto the sheet and let it dry one more time.
  6. Set your Z-probe (trigger height) correctly. It is important to get the right height with PEI, otherwise you'll have a hard time taking the part off the sheet; but can be done with an exacto knife then resand the sheet.
