Double Sided Textured PEI Sheet for QIDI X-Max 3 - Flexible Spring

In this review the CCTREE double sided textured PEI sheet is evaluated as a budget-friendly upgrade for larger heated beds. It is aimed at users of QIDI X-Max 3 and similar 330 x 330 mm printers who want a reliable, removable surface that simplifies part removal and supports a range of filaments; the single biggest reason to buy is the combination of a magnetic spring steel backing with textured PEI faces that deliver easy release and long-lasting durability for everyday PLA, PETG and TPU printing.

Key Features

• Double-sided textured finish: Each side offers a different texture so users can choose the surface that gives the best first-layer appearance and adhesion for their print job.
• Flexible spring steel backing: The steel sheet bends easily by hand so finished prints pop off without tools while the coating resists peeling and scratching.
• Wide filament compatibility: Works well with PLA, TPU, PETG, ABS and nylon when used with appropriate bed temperature and cleaning routines.
• Easy maintenance: The textured PEI wipes clean with water or isopropyl alcohol and regular cleaning restores reliable adhesion.
• Simple installation: The magnetic spring steel plate lays flat on a compatible heated bed and is ready to print, saving time on setup.
• Cost-effective replacement: A budget choice for users who want durable performance without buying an expensive branded build plate.

Who It's For

This sheet is best for owners of QIDI X-Max 3, Geetech A30 Pro and similar 330 x 330 mm printers who want a durable, removable print surface that reduces post-print handling. Hobbyists and small workshops printing mostly PLA, PETG and flexible filaments will appreciate the ease of removal and textured finish for improved first-layer looks.

Those who need extremely high temperature resistance above typical hotbed ranges or who require a non-textured mirror finish for optical parts should look elsewhere; also users with smaller beds or non-magnetic heater plates must confirm compatibility before purchase.

Pros & Cons

Pros

• Reliable adhesion for common filaments once the surface is cleaned with IPA or water.
• Two different textures let users select the preferred surface for appearance and release.
• Durable spring steel layer that can be bent thousands of times without losing shape.

Cons

• Some users report mixed adhesion results depending on filament and bed temperature, so prep and tuning are still required.
• Not intended for continuous use at extremes above typical heat bed limits; check recommended temperatures for certain high-temp filaments.

Our Verdict

The CCTREE double sided textured PEI spring steel plate is a practical, value-oriented upgrade for 330 x 330 mm printers that need a removable, durable surface. It is particularly good for PLA and flexible filaments, makes part removal simple by bending the sheet, and performs well when the surface is kept clean; sensible users who tune bed temperature and follow cleaning recommendations will find it a useful, long-lived accessory.

Frequently Asked Questions

Will this fit my printer?
The sheet is 330 x 330 mm and is intended for QIDI X-Max 3, Troxy X3S/X5SA Pro, Geetech A30/A30 Pro and other printers with a matching magnetic heated bed.

How do I get good adhesion?
Wipe the surface with isopropyl alcohol or water and a lint-free cloth before printing; avoid grease and residue for best first-layer adhesion.
