Who it fits
Good fit for
You should choose this sheet if you own an Elegoo Neptune 3 Pro, Neptune 4, Anycubic Kobra, Ender 3 series, or CR 20 models. It suits users who want to eliminate tape or glue. The magnetic design helps those who swap beds often. The textured PEI is ideal for PLA, PETG, ABS, and PEEK filaments. If you need a reliable surface that pops prints off easily, this size fits your setup perfectly.
Who should skip it
Skip this option if your printer requires a build plate larger than 235 by 235 millimeters. The data shows smaller sizes like 257x257mm or 315x310mm are available, so check your exact dimensions first. If you need a smooth PEI finish instead of textured, this is not the right choice. It is also not suitable for printers that do not support magnetic bed attachment systems.
Verdict: This sheet offers a practical, spec-driven upgrade for compatible printers. It simplifies print removal through its flexible steel and textured surface.
Key specs for this PEI sheet
Primary Material: Spring stainless steel, PEI
This sheet combines a flexible steel base with a PEI coating. The steel allows you to bend the plate to pop prints off easily. The PEI surface provides strong adhesion for materials like PLA and PETG. You get reliable first layers without needing glue or tape. This combination works well for users who want easy removal and consistent print quality on FDM printers.
Dimensions: 235 x 235 mm
The build area measures 235 by 235 millimeters. This size fits specific printer models like the ELEGOO Neptune 3 Pro and Ender 3 series. You should check your printer’s bed size before buying. If your printer requires a larger area, you might need a different size option. This dimension defines the maximum volume for your rectangular prints.
Build Surface Type: Textured PEI
The surface has a textured finish rather than a smooth one. This texture helps certain filaments grip better, reducing the chance of warping. It is ideal for users who struggle with prints sticking too tightly or sliding around. You will get a slightly rougher bottom layer on your prints compared to smooth sheets. This finish is popular for general-purpose printing tasks.
Weight: 1.06 pounds
The sheet weighs 1.06 pounds. This weight indicates a sturdy construction that can handle heat cycles without bending excessively. It is heavy enough to stay flat on the bed but light enough to handle easily. You do not need to worry about it being too flimsy. This mass helps maintain stability during long print jobs on compatible printers.
Build Plate Materials and Dimensions
The listing describes this build plate as a composite of spring stainless steel and PEI powder. You get a textured PEI surface on one side, which the manufacturer states offers strong adhesion for filaments like PLA, PETG, and ABS. The steel core provides the flexibility needed to bend the sheet and release prints without tools. This combination aims to eliminate the need for tape or glue, according to the listing.
The dimensions are fixed at 235 by 235 millimeters, which equals 7.87 by 7.87 inches. The height is listed as 0.79 inches, and the total weight is 1.06 pounds. These measurements match the bed sizes for several popular FDM printers, including the Elegoo Neptune 3 Pro, Neptune 4, and various Ender 3 models. The magnetic backing allows for quick removal and installation on compatible heated beds.
This specific model, identified as COMCXTB2-CA1, is designed for direct replacement. You do not need to adjust the printer’s software settings for the size, as it fits the standard build area. The textured finish helps prevent warping for materials that shrink during cooling. If you print with PEEK or other high-temperature filaments, the steel construction can withstand the heat cycles better than glass or bare aluminum plates, according to the product data.
Setup And Everyday Use Guide
This PEI sheet is designed for easy installation on compatible FDM printers. The listing confirms it adheres well to magnetic build surfaces. You simply place the 235 by 235 millimeter plate onto your printer’s heated bed. The magnetic backing helps keep it in place during printing. The steel core is flexible, allowing you to bend the plate slightly. This action helps pop prints off the surface after they cool. You do not need tape, glue, or a shovel to remove your models. The textured PEI surface provides strong adhesion for various filaments. The manufacturer states it works well with PLA, PETG, ABS, and PEEK. The PEI coating is resistant to heat cycles, which is important for daily use. You can print repeatedly without worrying about the surface degrading quickly. The sheet is removable, so you can clean it or swap it if needed. It fits several popular printer models. These include the ELEGOO Neptune 3 Pro, Neptune 4, Anycubic Kobra, Ender 3 series, Ender 5 series, and CR 20 variants. The dimensions match standard beds for these machines. If your printer has a different size, you may need a different variation. The product comes in four size options. The weight is 1.06 pounds. This makes it sturdy enough for regular printing but light enough to handle easily. You can cut the sheet to fit smaller build areas if necessary. This feature adds flexibility for different project sizes. The golden yellow back indicates the steel side. The one-sided textured coating ensures consistent print results. Daily use involves placing the plate, printing, and flexing it to release parts. This process reduces anxiety about stuck prints. The material choice supports long-term reliability. You get a durable surface that withstands frequent heating and cooling. This setup is practical for users who want consistent adhesion without extra supplies.
Before You Buy This PEI Sheet
You should verify your printer’s magnetic bed compatibility before purchasing this Comgrow sheet. The listing specifies support for ELEGOO Neptune 3 Pro, Neptune 4, and Anycubic Kobra models, among others. Ensure your existing heated bed has a magnetic surface to accept the plate. You may need to adjust your first layer calibration, as the textured PEI surface offers different adhesion than glass or bare steel. Regular cleaning with isopropyl alcohol is recommended to maintain print quality and remove residual filament. This sheet fits well alongside other replacement plates in our 1 options. It provides a flexible, durable solution for users who struggle with print removal. The spring steel core allows you to bend the plate slightly to release finished objects. Consider this if you want a low-maintenance build surface that handles heat cycles well. It is a practical upgrade for standard FDM printers requiring a 235 by 235 millimeter area.
Check before you buy
- Check if your printer uses a magnetic heated bed for proper adhesion.
- Confirm your model is listed, such as ELEGOO Neptune 3 Pro or Anycubic Kobra.
- Ensure you have isopropyl alcohol for regular surface cleaning and maintenance.
- Verify your printer’s build volume matches the 235 by 235 millimeter dimensions.
