Magnetic vs Textured PEI Build Plates
Build Surface Texture
The Comgrow 235x235mm Textured PEI Spring Steel Sheet features a textured surface with PEI powder sprayed on top. This texture provides excellent grip for a wide range of materials, including PLA, PETG, ABS, and PEEK. The textured finish helps prevent warping and ensures strong first-layer adhesion. In contrast, the Comgrow 235x235mm Magnetic Build Surface is described simply as black. The data does not specify a textured coating for this model. You get a smooth magnetic sheet. This smooth finish may require adhesive aids like glue sticks or hairspray for certain filaments to ensure prints do not detach during cooling. The PEI sheet offers a ready-to-print textured advantage.
Material Composition
Material choice significantly impacts durability and print release. The Comgrow 235x235mm Textured PEI Spring Steel Sheet is constructed from spring stainless steel with a PEI coating. This combination offers high strength, heat resistance, and flexibility. The spring steel allows you to bend the plate slightly to pop prints off easily. The Comgrow 235x235mm Magnetic Build Surface lists its weight and dimensions but does not explicitly state the base material in the provided specs. It is a magnetic sheet, likely plastic or coated metal, but the specific alloy or polymer is not detailed. The PEI spring steel construction provides a clear advantage in terms of known thermal stability and mechanical flexibility for model removal.
Thickness and Profile
Profile height affects how the build plate sits on the magnetic base. The Comgrow 235x235mm Magnetic Build Surface has a listed height of 0.08 inches. This is a very thin profile, sitting close to the hot bed. The Comgrow 235x235mm Textured PEI Spring Steel Sheet has a listed height of 0.79 inches. This is significantly thicker, nearly ten times the profile of the magnetic sheet. The thicker PEI sheet may provide a slight buffer or different Z-height offset, which you must account for during printer leveling. The thinner magnetic sheet offers a lower profile, potentially reducing the risk of nozzle collisions if your printer’s Z-offset is not perfectly calibrated.
Weight
Weight influences how the plate interacts with the magnetic base and handling. The Comgrow 235x235mm Magnetic Build Surface weighs 8.82 ounces. This is a light, low-profile sheet. The Comgrow 235x235mm Textured PEI Spring Steel Sheet weighs 1.06 pounds. This is substantially heavier due to the spring steel construction. The heavier PEI sheet may stay more securely in place during printing, reducing the chance of shifting. However, the lighter magnetic sheet is easier to handle and store. The weight difference is significant, with the PEI sheet being over twice as heavy as the magnetic sheet.
Compatibility and Fit
Both plates share the same build area size of 235x235mm. The Comgrow 235x235mm Textured PEI Spring Steel Sheet explicitly lists compatibility with ELEGOO Neptune 3 Pro/4, Anycubic Kobra, Ender 3 series, CR 20 series, and Ender 5 series. It is designed to stick well to magnetic bases. The Comgrow 235x235mm Magnetic Build Surface is labeled as a Creality Original Ultra Removable Magnetic surface. It is designed for magnetic attachment. Both fit the same bed dimensions. The PEI sheet provides a broader list of compatible printer models in its description, while the magnetic sheet is tied to the Creality magnetic ecosystem. Both offer a secure magnetic connection for the specified bed size.
Choose the right build plate for you
Users wanting easy print removal
The textured PEI spring steel sheet flexes to pop prints off easily. Its PEI powder surface grips PLA, PETG, ABS, and PEEK well. You avoid using tape, glue, or shovels. The flexible steel allows simple removal by bending the sheet slightly after cooling.
Buyers preferring a smooth surface
This magnetic build surface offers a smooth black finish. It attaches firmly to the hot bed when aligned correctly. The sheet is lightweight at 8.82 ounces. You get a simple, flat printing area that works with the magnetic base system for quick swaps.
Those needing material versatility
The PEI spring steel sheet supports a wide range of filaments. It handles heat cycles from PLA to PEEK without issues. The textured surface provides consistent adhesion. You do not need additional adhesives. The flexible design ensures models release cleanly after printing.

Frequently asked questions
Which Comgrow build plate is better for removing prints?
The Comgrow 235x235mm Textured PEI Spring Steel Sheet is better for removal. Its flexible spring steel design allows you to bend the plate, popping prints off easily. This avoids the need for shovels or scrapers. The magnetic surface requires more effort to detach prints without flexing the plate.
Does the magnetic build plate have a textured surface?
No, the Comgrow 235x235mm Magnetic Build Surface has a standard smooth finish. It is black and designed for easy removal via magnets. The textured PEI sheet is the only option with a rough surface for better grip. You must choose between smooth magnetic ease or textured adhesion.
What materials stick best to the textured PEI sheet?
The textured PEI surface provides excellent grip for PLA, PETG, ABS, and PEEK. The PEI powder sprayed on top enhances adhesion for these common filaments. The smooth magnetic plate is less specialized for specific material grips and focuses on standard removal convenience instead.
How thick is the Comgrow magnetic build plate?
The Comgrow 235x235mm Magnetic Build Surface is 0.08 inches thick. The Textured PEI Spring Steel Sheet is significantly thicker at 0.79 inches. This difference in height affects how the plate sits on the bed and its overall rigidity during printing.
Is the Comgrow magnetic plate heavy?
The magnetic build plate weighs 8.82 ounces. The textured PEI spring steel sheet is much heavier at 1.06 pounds. The magnetic version is lighter due to its thinner construction. The spring steel version includes a thicker metal base for flexibility and durability.
Do both plates fit 235x235mm printers?
Yes, both plates measure 235x235mm. The magnetic plate is 9.25 inches square. The textured PEI sheet is also 7.87 inches square, which converts to the same metric size. Both are designed to fit the same standard bed area for Creality and Comgrow printers.
Which plate is better for beginners?
The Textured PEI Spring Steel Sheet is often better for beginners. It offers reliable adhesion for various materials and easy removal by flexing the plate. You do not need glue or tape. The magnetic plate requires more care to remove prints without damaging them.
