| Surface | Why consider it? | Check before buying |
|---|---|---|
| Textured PEI | For a textured underside. | Printer size, material guidance and the permitted cleaning routine. |
| Smooth surface | For a flatter-looking underside on a visible part. | The exact coating and whether it needs a release or adhesion layer. |
| Low-temperature plate | For a different bed-temperature routine. | The recommended materials, temperatures and removal instructions. |
Compare each plate with the setup it needs
Different coatings can require different temperatures or surface treatments. Forcing all of them to use an unsuitable identical recipe would tell you little about which is easiest to live with.
A practical comparison should record first-layer adhesion, lifted corners, underside texture and removal after cooling. It should also say how the plate was cleaned and whether an adhesive or release layer was used.
A plate we have used in the published test
The Copymaster print used Bambu Textured PEI. Its supported block and bar were close to their design dimensions. That result describes this plate, material and setup; it does not rank it above plates that were not in the test.
Before replacing a surface that used to work
Check the coating’s cleaning instructions and the first-layer setup. A cleaning problem is worth ruling out before buying another plate. Our cleaning guide sets out the checks without prescribing the same solvent for every coating.
