The Original Prusa magnetic heatbed is designed to hold a removable, double-sided, flexible print sheet, specifically designed for easy removal of printed objects from the print surface.
The special PA sheet is made for printing polyamides (Nylon) since their adhesion to standard PEI sheets is generally very poor. The sheet comes with a matt texture, similar to the satin print sheet with a PEI surface. The sheet is compatible with most polyamides and PETG. Other materials may have insufficient adhesion and should be printed on our standard PEI sheets.

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.
Note that the sheets for the CORE One and the MK series sheets are interchangeable, just with different designs.
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.
If your print surface is perfectly clean and all grease has been removed by wiping it with a paper towel soaked in water and dish-washing soap, the first layer height is set properly, and the print won’t stick, check out 1層目の問題.
Keep in mind that polyamides in general tend to warp more than other materials. Sometimes warping may be so strong that larger models (or with dense infill) detach from the surface, even over the best surface adhesion. If you experience such strong warping, we recommend using another type of PA for selected prints - for example, our Prusament PA11 Carbon Fiber shows almost no warping at all. You can find more in the articles about polyamide and warping.
PA Nylon print sheet has a special surface layer with a smooth texture and a matt look. The surface layer is partially translucent and may show a specific “texture” of lengthwise or diagonal lines, or varying color shades. These color variations are characteristic of the material under the topmost layer and don’t affect sheet performance.
As a result of the temperatures to which the plate is exposed during printing, its surface gradually becomes glossier or may develop smaller, duller areas. This visual change does not adversely affect the printing properties and is not considered a reason for a warranty claim.
Note that the PA Nylon sheet wear is especially noticeable at the Z probing points, where the nozzle leaves visible marks on the surface. This does not affect the surface adhesion and overall printability.
A new batch of the PA Nylon sheet will be released during July / August 2024. The new version will get a slightly rougher surface texture. This change will not affect the print sheet's functional properties. You can examine the changes in the gallery below.
