Print Sheet, Prusa Steel Spring PEI Build Plate for Prusa Mini+ (satin)

Replacement steel spring PEI build plate designed for the Prusa Mini+ with a satin surface finish. This print sheet combines a flexible spring steel substrate with a PEI-coated top layer to provide a flat, durable printing surface that supports reliable first-layer adhesion and straightforward part removal by flexing the sheet. The satin texture reduces visible layer marks while maintaining consistent adhesion for common filament types used on the Mini+.

Advantages

The satin steel spring PEI plate offers consistent adhesion across the build area, good dimensional stability, and a durable surface that tolerates repeated use. Its flexibility allows easy removal of completed parts by bending the sheet, reducing the need for scraping tools. The satin finish minimizes glossy reflections and improves surface uniformity, while the steel substrate resists warping and keeps the plate flat during printing.

Suitable for

• Printing standard filaments such as PLA and PETG on the Prusa Mini+
• Users who prefer a factory-style removable spring steel build plate
• Small to medium-sized prints that benefit from a flexible removal method

Key specifications

• Flexible spring steel substrate for simple part removal by flexing
• PEI-coated top layer providing reliable first-layer adhesion
• Satin surface finish to reduce surface gloss and visible artefacts
• Compatible shape and mounting system for the Prusa Mini+ build platform
• Durable construction designed for repeated bending and printing cycles

How to use

Install the steel spring PEI plate onto the Prusa Mini+ by aligning it with the printer’s magnetic or clip-based mounting system and securing it according to the printer manufacturer’s instructions. Level or live-adjust the nozzle height to achieve a correct first layer calibration for your filament and print profile. After a print completes and the plate has cooled, remove parts by carefully flexing the steel sheet to release adhesion; larger or more stubborn parts may require gentle assistance with a flat scraper, taking care not to damage the PEI surface.

Usage recommendations

For best results, clean the PEI surface with isopropyl alcohol before each print session to remove oils and residues. Use appropriate bed temperature and first-layer settings for the filament in use, and avoid excessive scraping or sharp tools when removing parts to preserve the PEI coating.
