Textured PEI Plate
The Textured PEI Plate (not to be confused with the Engineering Plate) has a coarser texture and is especially suited for TPU and other flexible materials, as well as a range of common materials.
Properties
- Surface: Coarse PEI texture — gives a distinctly textured bottom surface
- Adhesion: Excellent mechanical grip, especially for TPU
- Release: Very easy after cooling — flex the plate and prints release
- Max bed temperature: 100 °C
Best suited for
- TPU — this is the best plate for flexible materials
- PLA and PLA+ — good adhesion, nice textured bottom surface
- PETG — with a small amount of glue stick
- PLA-CF — without glue stick
Compatibility
| Material | Suitability | Glue stick |
|---|---|---|
| TPU | ★★★★★ | No |
| PLA | ★★★★★ | No |
| PLA+ | ★★★★★ | No |
| PETG | ★★★★ | Little (recommended) |
| PLA-CF | ★★★★ | No |
| ABS | ★★★ | Yes |
| PA12 | ★★★ | Yes |
TPU on Textured PEI
TPU adheres perfectly to Textured PEI without glue stick:
- Set bed temperature to 30–45 °C
- Calibrate Z-offset carefully — slightly higher than for PLA
- Let bed cool below 30 °C after printing
- Flex the plate gently — TPU releases without effort
:::tip Cold release TPU releases from Textured PEI excellently upon cooling. If you have trouble removing the print, wait until the plate is completely cold (20–25 °C) and flex more firmly. :::
Maintenance
Textured PEI is robust and easy to maintain:
# Between prints:
- Wipe with IPA and lint-free paper towel
# Monthly (or when adhesion is poor):
- Wash with warm water and mild dish soap
- Rinse and dry thoroughly
- Finish with an IPA wipe
Surface of finished print
The coarse texture gives a distinctive patterned underside on all prints. This is:
- Desirable for prototypes and functional parts (better grip)
- Undesirable for decorative/visual prints (use Cool Plate for a smooth surface)
