Textured steel sheet

The Original Prusa magnetic heatbed is designed to hold a removable, double-sided, flexible spring-print sheet, specifically designed for easy removal of printed objects from the print surface.

The powder-coated sheet, also referred to as the textured sheet, has its surface covered with a special polymer (Ultem PEI) to ensure perfect adhesion. These have been used in our print farm for many years and are perfect when printing a lot of high-adhesion filaments like PETG, and are also ideal for printing flexible filaments (TPU). It has a rougher texture than the Satin sheet and is more durable with some filaments than the Smooth sheet.

Print sheet color

The exact color depicted in the e-shop and our knowledge base may differ from yours. All sheets are checked and verified to be within tight specifications. These specifications are both considering the manufacturing method and the sheet's function (adhesion and durability used with certain material types), but not the cosmetic aspect of the sheet or pattern left on printed parts. We can not guarantee the pattern left on your printed objects will match perfectly from sheet to sheet.

Main attributes

• Textured finish.
• Double-sided! Both sides can be used interchangeably.
• Thinner than its smooth counterpart.
• Ideal for extensive printing of PETG, CPE, TPEE/TPU.
• No need for glue-stick with flexible filaments (TPU/TPEE).
• Prints automatically detach after the sheet cools down.
• To be cleaned with ~90% IPA or denatured alcohol when cold. Do not use anything made for skin! It can contain oils/sugars that ruin adhesion.

Considerations

• Never clean the sheet with acetone! It will deteriorate the surface!
• Never apply ABS juice to it!
• Never put the sheet in the freezer.
• Prints from ASA, ABS, Nylon, and PC Blend require the application of a glue stick (separation layer).
• The live Z value needs to be readjusted when switching sheets if your printer uses a PINDA for bed leveling. See Steel sheet profiles.
• Not scratch-resistant. Do not use metal spatulas, etc., to remove the prints. We recommend printing a plastic spatula, like this one.
• Small PLA prints may require a Brim.

Supported printers

Note that the sheets for the CORE One and the MK series sheets are interchangeable, just with different designs.

• CORE One
• XL
• HT90
• MK4/S, MK3.9/S, MK3.5/S, MK3/S/+, MK2.5/S (Also offered as Factory second)
• MINI/+ (Also offered as Factory second)

Filaments

We have done a lot of testing and compiled our results for you to use. To easily see how to prepare your sheet for any filament type, please see our Material table.

Prints don’t stick

If your print surface is perfectly clean and all grease has been removed by wiping it with a paper towel soaked in isopropyl alcohol, ~90%. Also, make sure the first layer height is set up perfectly.

If your prints still do not adhere reliably to the print surface, try to wash the sheet in warm water (not hot!) with a few drops of liquid dish soap (not hand soap). This should not be done often, and do not submerge the sheet completely in hot water, but this can clean away oils/sugars that are not affected by rubbing alcohol. However, the textured sheet is not waterproof, so consider this a last resort, which should not be done often.
