QIDI Max4 dual-sided PEI plate

Original dual-sided PEI print plate designed for the 3D printer QIDI Max4. This is a flexible magnetic plate with a PEI surface on both sides, dimensioned for the large printing volume of the Max4 390 × 390 mm. The plate is designed for use with the printer's aluminum heated bed and is optimized for high-temperature printing up to a heatbed temperature of 120 °C.

Main advantages

• Full compatibility with QIDI Max4 Dimensions and design correspond to the original print plate supplied with the QIDI Max4 printer, including the magnetic attachment.
• Dual-sided PEI surface Both sides of the plate have a PEI layer for reliable adhesion. You can alternate sides depending on the material type or surface wear and extend the lifespan of the plate.
• Excellent adhesion and easy print removal The PEI surface provides very good adhesion for common and technical materials. After the plate cools down, the model usually releases, or it is enough to slightly bend the flexible sheet and the part detaches without force.
• Large print format 390 × 390 mm Fully corresponds to the large-format workspace of the Max4 printer (390 × 390 mm in the X and Y axes), so you can use the entire printing area without restrictions.
• Optimized for high temperatures The plate is intended for the Max4 heated bed with a temperature up to 120 °C, which is suitable for printing materials such as ABS, ASA, PC, PA, and carbon or glass fiber composites.
• Convenient maintenance The surface just needs regular cleaning with isopropyl alcohol to remove adhesive residues and grease from hands. Simple maintenance helps maintain stable adhesion for a long time.

Recommended use

• Designed for QIDI Max4 as a replacement or additional print plate.
• Suitable for materials:
  • PLA, PLA+
  • PETG
  • ABS, ASA
  • TPU (with appropriate adhesion settings)
  • PA, PC
  • Carbon and glass fiber composites (at correct temperatures and settings)

Tips for setup and use

• Before first use, perform Z-offset calibration after replacing or flipping the plate to the other side.
• For materials with very strong adhesion (PLA, PETG), it can help to:
  • slightly lower the bed temperature after the first layers,
  • use a separation layer (e.g., glue stick) for easier removal of prints.
• Do not leave the plate overheating for a long time without printing – this will extend its life and maintain a quality surface.

Technical parameters

Who is the plate suitable for

• For QIDI Max4 users who need an original replacement plate after the existing one is worn out.
• For those who want to have multiple plates in rotation (faster order switching, different materials and settings on separate plates).
• For advanced users of technical filaments who require reliable adhesion on a large format.

This dual-sided PEI print plate for QIDI Max4 is an ideal accessory for anyone who wants to get maximum quality, reliability, and operating comfort from their large-format printer.
