This glossy PEI sheet replaces the stock surface on the Ender-3, Ender-3 Pro, Ender-3 S, Ender-5 and CR-20 machines, matching their bed footprint exactly. The polished finish transfers onto the first layer, leaving a reflective underside that needs no sanding on lids, coasters and nameplates. PEI holds PLA, PETG and ABS well without glue stick or hairspray, and a quick wipe with isopropyl alcohol brings the grip back when it starts to feel tired. Because the sheet is spring steel, you flex it rather than prising parts loose, which spares both your fingers and the coating underneath.
Good for
- Reflective undersides on flat parts
- Upgrading a tired Ender-3 bed
- Printing without glue stick
- Coasters, lids and nameplates
