PA Nylon Powder-coated Print Sheet for Prusa i3 MK3/S/+, MK2.5/S, and MK4

Designed for Polyamide-Based Filaments

Polyamide (Nylon) is known for its excellent thermal and mechanical resistance, making it ideal for printing functional technical parts that require high temperature and mechanical resistance. However, printing with polyamide can be challenging due to its tendency to warp and its high moisture absorption. The Prusa PA Nylon Powder-coated Print Sheet addresses these challenges by providing a surface that enhances adhesion, particularly for PA11-type materials, which generally have lower adhesion on textured or satin print sheets.​

Cleaning and Maintenance

To maintain optimal performance, clean the print sheet only with pure water. Using common cleaning agents such as isopropyl alcohol (IPA) or acetone can lead to rapid deterioration of the surface. If grease-coated areas are present, use clean water with a drop of dishwashing detergent. The use of glue sticks is no longer required and is not recommended.

Compatibility and Usage

This print sheet is suitable for use with polyamide-based materials and PETG. Other materials may detach mid-print due to insufficient adhesion. It is important to note that consumable parts, such as PEI sheets (smooth, textured, nylon, etc.), are not covered by warranty as the coatings are designed to diminish over time unless failure has occurred due to a defect in materials or workmanship. Cosmetic damage, including but not limited to scratches, dents, cracks, or other cosmetic damage, is also not covered by the warranty. Only defective sheets on arrival are covered by warranty.​

Surface Wear and Visual Changes

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. With the Original Prusa MK4, 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.
