ELEGOO Dual-Sided PEI Build Plate for Neptune 4 Series

The ELEGOO Dual-Sided PEI Build Plate for the Neptune 4 Series is a replacement printing surface made from PEI and spring steel. The flexible base bends to release finished models during part removal. Bending the plate pops the print off cleanly, avoiding the damage a scraper could cause to the coating. The spring-steel construction holds up to repeated flexing. This makes it easier to remove rigid or oversized prints from the build area. The material combination also provides a stable platform for everyday printing.

The plate is dual-sided so you can switch between filament types. Matching the print surface to the material keeps adhesion consistent without glue or tape. Having a spare build surface to hand avoids downtime between jobs. The plate returns flat after flexing, so it stays ready for continuous printing schedules.
