Double-sided PET Phantom with PEI-coated surface for Creality 3D printer build plate 315×310 mm

Double-sided PET Phantom with PEI-coated surface for Creality 3D printer build plate 315×310 mm is a replacement and protective cover designed for Creality FDM printers. The product features a polyethylene terephthalate (PET) base with a PEI-coated working side that promotes adhesion for common filaments and a smooth reverse face for storage or alternative use. Sized to fit a 315×310 mm build plate, it serves as a durable, reusable printing surface that helps preserve the original heater table and simplifies first-layer consistency and part removal.

Advantages

The PET Phantom offers a PEI-coated top layer that improves adhesion for PLA, PETG and other commonly used FDM filaments without additional adhesives. Its double-sided design increases service life by allowing the user to flip or replace the active surface when needed. The sheet is thin enough to conform to the build plate for even heat transfer while providing a scratch-resistant surface that reduces wear on the printer's original bed.

Suitable for

• Replacement or protection of Creality 315×310 mm build plates
• Printing with PLA, PETG and similar FDM filaments
• Prototyping, hobby prints and small production runs
• Users seeking easier part removal and longer bed life

Key specifications

• Material base: PET (polyethylene terephthalate)
• Working surface coating: PEI (polyetherimide)
• Dimensions: 315 × 310 mm
• Double-sided: PEI-coated side and smooth reverse side
• Compatibility: designed for Creality build plates of matching size

How to use

Clean the printer build plate to remove dust, grease or residue before applying the PET Phantom. Align the sheet with the edges of the 315×310 mm build surface and press it down evenly to ensure full contact and consistent heat transfer. Heat the bed to your usual printing temperature for the chosen filament to improve initial adhesion. After printing, allow the plate to cool before attempting part removal; gently flexing the sheet or using a suitable removal tool will help detach prints without damaging the surface. If the active side becomes worn or contaminated, flip to the reverse side or replace the sheet.

Usage recommendations

For best results, use the PEI-coated side for standard printing with PLA and PETG. Maintain the surface by cleaning with isopropyl alcohol and avoid abrasive cleaners. Allow the bed to cool before removing prints and store the sheet flat to prevent warping. If adhesion issues occur, check bed leveling and first-layer settings before changing the surface.
