Attributes
- Ideal for printing PLA, HIPS, ABS/ASA, composite materials (metal/wood).
- Prints with sharp corners or a small first-layer area are less likely to detach.
- Scratch-resistant. Can be used with a metal spatula, however, cosmetic scratches may appear.
- Compatible with most types of filament.
- Little to no surface preparation, (other than cleaning).
- Clean with ~90% Isopropyl alcohol (IPA) or denatured alcohol.
- Can be cleaned with acetone, but do not overuse it (1-2 times per month).
Considerations
- Live Z value needs to be readjusted if you switch sheet-type.
- Some filaments, like PETG, ASA, ABS and PC Blend, may need a protective separation layer, like gluestick applied thinly before printing!
- Keep the sheet clean! Any grease will greatly reduce adhesion.
Maintenance
- Clean with ~90% IPA (isopropyl alcohol) or denatured alcohol when cold. Apply on unscented paper towel and rub the sheet down. Do not use anything made for skin! It can contain oils that ruin adhesion!
- 1-2 times a month it can be cleaned the same way with acetone if IPA cleaning is not sufficient.
- After extended use (1-2 years) the surface can smooth out further, which affects adhesion. Using high-grit sandpaper (600-1000), the PEI can be revived by light sanding, bring fresh PEI to the surface. The sheet will have a very light texture after this treatment.
- The smooth PEI film on the steel sheet can be replaced in case of extensive damage.
Prints don’t stick
If your print surface is perfectly clean and all grease has been removed by wiping it with a paper towel soaked in isopropyl alcohol 90% and if the first layer height is set up perfectly, yet your print still does not adhere reliably to the print surface.
