Pei vs Glass Build Plate: Which Should You Buy?

When a print lifts at the corners or sticks so well it will not come off, the build plate is often the cause. For pei vs glass build plate, the practical answer for most makers is a flexible spring steel plate: the CryoGrip listing describes bending the plate to release the print, and the plates in this guide fit the Bambu Lab printers they list. Glass is the rigid alternative for a maker who wants a surface that does not flex.

The pei vs glass build plate decision

Spring steel plates can flex, but bending is only one removal method. The BIGTREETECH CryoGrip listing describes bending the plate slightly to detach prints cleanly, with no scraping or prying tools. The UniTak3D listing, by contrast, describes easy removal from its smooth side without bending the sheet, and it asks the maker to wait until the platform has cooled down first.

A glass plate does not bend, so removal depends on the print releasing from a rigid surface.

Surface choice is the next split. The UniTak3D plate is double sided, with a textured side and a smooth side. The textured side is coated with black textured PEI, and the smooth side leaves a smooth bottom on the printed part. The BIGTREETECH CryoGrip plate is listed as a fine textured spring steel sheet, while the BIQU CryoGrip plate lists a delicate surface texture. The Wefuit plate adds a holographic texture that shows different colors under different lighting.

Adhesion: what the listings promise

Adhesion is where the listings differ most. The CryoGrip listings promise strong first layer adhesion and warp-free printing for PLA and PETG. Both CryoGrip listings note adhesion not as strong as the Frostbite plate with PLA and PETG.

Glue is a split point. The UniTak3D listing states the smooth side requires glue sticks except for PLA filaments. The BIGTREETECH CryoGrip listing describes keeping away from glue.

The UniTak3D listing also states its black textured PEI adhesion is stronger than gold PEI coating adhesion.

Removal: bending the plate vs waiting for cooling

Bending removal is fast on the CryoGrip plate. The BIGTREETECH CryoGrip listing describes bending the surface slightly so prints detach cleanly, with no scraping or prying tools. The UniTak3D listing describes easy removal from the smooth side without bending the sheet.

Cooling rules differ by listing. The CryoGrip listings describe removing the plate right after printing, since the handle area stays cool enough to touch even with the bed at 100℃. The UniTak3D listing asks the maker to wait until the platform has cooled down before removing the model, to avoid damage to the surface.

The Wefuit listing describes removal after the printed model cools down, with an easy lift after cooling.

Heat limits and filaments

Heat limits decide which filaments each plate handles. The UniTak3D listing rates its textured side to 300℃ and its smooth side to 200℃. The Wefuit listing rates its surface to 200°C. The BIGTREETECH CryoGrip listing states compatibility with materials with nozzle temperatures below 300℃. That figure is a nozzle temperature limit, not a plate heat rating, unlike the UniTak3D and Wefuit plate ratings in the same paragraph.

Low temperature printing is a stated CryoGrip feature. The BIQU CryoGrip listing gives PLA at 45-55℃ and PETG at 60-70℃. The BIGTREETECH CryoGrip listing gives PLA at 45-55℃ and PETG at 60-75℃. The 2 listings differ on PETG, so check the listing for the plate you buy.

The UniTak3D plate names the most filaments: PLA, ABS, ASA, PETG, TPU, Nylon, PA and PC. The CryoGrip listings list PLA, PETG, ABS, PA and other filaments. The Wefuit listing recommends PLA, TPU, PETG and ABS, and asks the maker to adjust parameters for other filaments.

Gear: 4 plates for Bambu Lab printers

All 4 plates here measure 257x257mm. They are ranked below by listing completeness: the depth of stated specs, care notes and compatibility detail. The ranking reflects the listings, not a measured score.

Top pick: the BIGTREETECH CryoGrip Pro Glacier Panda plate. Its listing covers low temperature printing, a 7-layer coating, AR code stickers for X1C recognition, and cleaning with water and soap or alcohol. It fits Bambu Lab X2D, P2S, P1S, P1P, X1C, X1E and A1 printers.

Next: the BIQU CryoGrip Pro Glacier plate. Its listing covers the same 7-layer cobalt oxide coating, a hollow-out handle design, and AR code markings for X1 build plate locating scans. It fits Bambu Lab P1S, P1P, P2S, X1C, X1E, X2D and A1 printers.

Next: the UniTak3D PEI plate. Its listing covers a double-sided smooth and textured surface, heat resistance to 300℃ on the textured side, and a broad filament list. It fits Bambu Lab X2D, A1, P2S, P1P, P1S, X1, X1C and X1E printers.

Last: the Wefuit holographic texture PEI plate. Its listing covers 2 patterns on a spring steel sheet, heat resistance to 200°C, and a recommended filament set of PLA, TPU, PETG and ABS. It fits Bambu Lab X2D, P2S, X1, X1C, X1E, P1P, P1S and A1 printers.

Care and cleaning

Care notes differ by listing. The BIGTREETECH CryoGrip listing states cleaning with water and soap or alcohol, and a wipe restores adhesion. The UniTak3D listing asks for regular cleaning with a soft cloth, and warns against strong chemical reagents and strong detergents. The Wefuit listing asks for a wipe before each use, and a dry wipe after a wet wipe.

Setup notes matter too. The BIGTREETECH CryoGrip listing asks the maker to disable build plate detection on X2D and P2S printers, while the BIQU CryoGrip listing mentions closing build plate printing detection for P2S only. The Wefuit listing suggests turning off build plate position detection for X1 series printers. The UniTak3D listing asks the maker to peel off the protective film on the smooth side before use, and to level the plate again after changing sides.

FAQ: lasers and CNC

Does a PEI plate need glue?

It depends on the plate and the side. The UniTak3D listing states its smooth side requires glue sticks except for PLA filaments. The BIGTREETECH CryoGrip listing describes keeping away from glue.

Can these plates print PLA and PETG?

Yes. The CryoGrip listings give PLA at 45-55℃ and PETG at 60-70℃ or 60-75℃, depending on the listing. The UniTak3D listing lists PLA and PETG among its supported filaments. The Wefuit listing recommends PLA and PETG among its filament set.

How do you remove a print from these plates?

It depends on the plate. The BIGTREETECH CryoGrip listing describes bending the surface slightly so prints detach cleanly, and the CryoGrip listings describe removing the plate right after printing. The UniTak3D listing describes easy removal from the smooth side without bending the sheet, but only after the platform has cooled down. The Wefuit listing also describes removal after the printed model cools down.

What size are these plates?

All 4 plates here measure 257x257mm. Check the printer list for the plate you buy, since the listings name slightly different Bambu Lab models.

Do I need to change settings for a new plate?

Sometimes. The BIGTREETECH CryoGrip listing asks the maker to disable build plate detection on X2D and P2S printers, while the BIQU CryoGrip listing mentions closing build plate printing detection for P2S only. The Wefuit listing suggests turning off build plate position detection for X1 series printers. The Wefuit listing also suggests choosing Smooth PEI Plate/High Temp in the slicer. The UniTak3D listing asks the maker to level the plate again after changing sides.
