- You prefer a spring steel base for durability
Verdict: Choose the Comgrow plate if your printer uses a 235x235mm bed and you need a straightforward magnetic replacement. The BIQU plate is better for larger 257x257mm systems, especially if you want the flexibility of dual-sided printing textures. Both options provide magnetic removal for easy part release.
Comgrow vs BIQU Build Surface Specs
Build Surface Type
The BIQU build plate offers a versatile double-sided design, featuring a smooth PEO surface on one side for diamond patterns and a textured PEI surface on the other for textured prints. This allows you to switch between finish types without changing hardware. The Comgrow product is listed simply as a magnetic build surface with a black color. While the Comgrow data confirms its magnetic nature, it does not specify a dual-sided texture or distinct surface coatings like PEO or PEI. You get more printing flexibility with the BIQU option if you need both smooth and textured results from a single plate.
Platform Size
Size compatibility is the first major difference between these two accessories. The Comgrow magnetic build surface is designed for a 235x235mm platform, which is standard for many entry-level printers like the Ender 3 series. In contrast, the BIQU build plate is sized at 257x257mm, targeting larger platforms found in Bambu Lab printers such as the P1P, P1S, X1C, and A1 models. These sizes are not interchangeable. If you have a larger printer, the Comgrow plate will not fit. If you have a smaller bed, the BIQU plate will be too large. You must choose the size that matches your printer's exact bed dimensions.
Material Composition
The BIQU build plate is constructed from spring steel, providing a flexible base that aids in print removal. It is coated with high-quality PEO and PEI materials, offering high temperature stability, flame retardancy, and high strength. The Comgrow product data does not explicitly list the base material or specific coating types, only describing it as a magnetic sticker with a black top layer. The BIQU plate’s spring steel construction suggests better durability and resistance to deformation compared to a standard magnetic sticker. You get a more robust material profile with the BIQU option, which may offer better long-term performance under heat and stress.
Print Removal
Both products utilize magnetic adhesion to simplify the process of removing finished prints. The Comgrow surface relies on strong magnetic adsorption between the soft magnetic sticker and the hot bed, requiring correct orientation during installation. The BIQU plate also uses an upgraded magnetic build surface but emphasizes ease of use by stating that bending the plate causes prints to pop up immediately. This flexible spring steel design helps eliminate printing anxiety by ensuring prints detach cleanly without tools. While both use magnets, the BIQU plate’s flexible nature provides a more active removal mechanism compared to the static magnetic attachment of the Comgrow surface.
Flatness and Stability
Flatness is critical for the first layer of any 3D print. The BIQU build plate is described as having a flat construction surface to ensure high flatness, which helps models attach firmly to the platform. It also boasts excellent flatness for the bottom of the print. The Comgrow product data does not explicitly mention flatness specifications or construction quality beyond the magnetic adhesion. The BIQU plate’s emphasis on flat construction and high stability suggests it may provide a more consistent first layer. You get better assurance of surface uniformity with the BIQU plate, which is important for print quality.
Choose the right build plate
You have a 235x235mm printer
The Comgrow surface matches your 235x235mm bed exactly. It is a single-sided black plate measuring 9.25 by 9.25 inches. The magnetic base ensures firm adsorption for reliable printing. You get a straightforward solution that fits your hardware dimensions without needing adapters or modifications.
You use a 257x257mm printer
The BIQU plate is sized for 257x257mm platforms like the Bambu Lab P1P or X1C. It features a double-sided design with smooth PEO and textured PEI finishes. This allows you to print different surface patterns on one plate. The spring steel base provides high temperature stability and strong adhesion for larger builds.
You want two surfaces in one
BIQU offers a versatile double-sided plate with smooth PEO and textured PEI. You can switch between diamond patterns and textured prints without changing hardware. The spring steel construction ensures flatness and stability. This dual functionality saves space and cost, giving you more printing options from a single accessory.
