Introducing the Prusa Smooth PEI Steel Sheet, the ultimate surface upgrade for your 3D printing bed. Designed for compatibility with Prusa printers, this steel sheet features a smooth PEI coating that ensures excellent adhesion and effortless print removal. Say goodbye to messy adhesives and warped prints—achieve consistent, high-quality results with the Prusa Smooth PEI Steel Sheet.

The MK52 heatbed has embedded high Curie temperature magnets. These magnets are able to firmly hold removable spring steel sheets.

The Satin sheet further expands our line-up of print sheets. In terms of printing properties, the Satin sheet sits between the smooth and textured variants. Its powder-coated surface with lightly textured matte finish offers an optimal level of adhesion, especially when printing PLA and PETG materials. It is fully compatible with a wide range of common and less-common filaments, such as ABS, ASA, FlexFill 98A, Polycarbonate and more. A vast majority of materials can be printed without a separation layer (e.g. glue).

Polycarbonate - prints better on satin (compared to smooth and textured sheets) - when printing with PC often, glue stick layer is recommended to prevent possible damage to the sheet.

WARNING: Never clean the Satin powder-coated spring steel sheet with acetone! Doing so will create microfractures in the texture, which will make the surface deteriorate over time.

Note: Consumable parts, such as PEI sheets (smooth, textured, 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.

If you love modifying your 3D printer, adding new features, and tweaking it to your liking, our accelerometer module for printer developers will surely come in handy! With it, you can easily measure the resonance frequency of each axis and recalibrate your Input Shaper to the optimal values, ensuring your 3D printer operates with maximum efficiency.

Our printers come from the factory with pre-configured, optimised Input Shaper values that have been collected and fine-tuned across many of our machines. Therefore, with a standard stock printer, you won’t ever need additional tuning, as any potential improvement after recalibration would be rather insignificant.

However, some modifications, such as a mod on the Nextruder, can impact the printer’s construction to the extent that the original Input Shaper values are no longer valid. You can then easily use our accelerometer to recalibrate it. Simply plug it into the xBuddy board using the connector on the back of the MK4S 3D printer, attach it to the printhead and the heatbed, and perform a full recalibration of the Input Shaper.

Although this tool is intended for developers, installing the accelerometer on the printer and using it is very easy.
