PEI print surface for large-format 3D printing

The 660 x 630 x 0.5mm PEI Sheet is a high-performance build surface designed for the Modix Big 60 and other large-format 3D printers. The PEI surface provides excellent adhesion during printing while allowing easier part removal after cooling.

Polyetherimide is widely used as a 3D printer build surface because it helps reduce the need for additional adhesives. For large parts and long print jobs, that means more consistent first-layer performance across the bed.

Key features of the 660 x 630mm PEI sheet

• Custom fit for the Modix Big 60: Sized to cover the entire print bed for consistent adhesion across large-format prints.
• Strong first-layer adhesion: Supports PLA, ABS, PETG, TPU, and other common filaments without relying on glue or tape.
• Heat-resistant construction: Built to withstand high temperatures and repeated heating cycles without warping or degrading.
• Thin 0.5mm profile: Flexible enough for application on a heated bed or a magnetic flex plate system.
• Easier part removal after cooling: Printed parts release more easily once the surface temperature drops, helping reduce print damage during removal.
• Scratch and wear resistance: Designed for long-lasting performance in frequent or high-volume printing environments.

Where this PEI sheet is used

• Large-format 3D printing with the Modix Big 60: A full-size PEI surface helps maintain reliable bed coverage for oversized parts and longer builds.
• Multi-material and higher-temperature printing: The PEI sheet supports a range of common filaments used for prototypes, functional parts, and general production work.
• Custom build plate surfaces for professional use: Suitable for industrial and professional 3D printing setups that need a durable, repeatable print surface.
