Prusa Mini MK3S Magnetic Heated Bed 24V 120W with PEI Coating and N50H Magnet Option

This replacement hot bed is designed to fit Prusa Mini and MK3S 3D printers, providing a magnetic surface that makes print removal quick and easy. The PEI coating offers consistent adhesion for PLA, PETG, ABS, and other common filaments without needing glue or tape. The integrated 24V 120W heating element ensures fast heat-up and stable temperatures, while the included thermistor delivers accurate feedback for precise bed temperature control. Choose between the version with a strong N50H magnet or without magnet to suit your existing setup.

Features and Construction

The heated bed is built around a rigid metal core with a PEI surface layer and optional magnetic sheet. Electrical components are pre-wired for straightforward installation.

Material and Build

The PEI coating provides a smooth, durable surface that grips filament during printing and releases prints once the bed cools. The underlying metal plate ensures flatness across the entire print area. The N50H magnet variant adds a strong magnetic layer that holds flexible steel sheets securely in place.

Size and Practical Fit

This bed is sized for Prusa Mini and MK3S printers. Exact dimensions are not specified in the source, but the pattern matches the standard Mini/MK3S mounting holes and wiring connectors. The package includes two screws and nuts for attachment.

Uses and Placement

Ideal for upgrading or repairing a Prusa Mini or MK3S printer, this heated bed replaces worn or non-magnetic surfaces. It works with both direct-extrusion and Bowden setups.

Event or Professional Use

In a print farm or workshop, the magnetic PEI surface reduces downtime between prints because parts lift off easily without scraping. The consistent 24V 120W heating ensures reliable first-layer adhesion across multiple back-to-back prints.

Everyday Home Use

Hobbyists benefit from the simple install and the PEI surface's compatibility with many filament types. The magnetic option allows quick swapping of build plates for different projects, keeping the workflow smooth.

Benefits and Buying Value

This bed offers a direct replacement that improves print reliability and reduces the need for consumables like glue sticks or painter's tape. The choice of magnet version lets buyers customise the upgrade to their existing build surface.

Reuse and Low Maintenance

The PEI coating lasts through many print cycles with proper care. Cleaning with isopropyl alcohol between prints maintains adhesion without requiring abrasive pads or chemical treatments.

Why Choose This Product

With its 24V 120W heating, integrated thermistor, and optional N50H magnet, this bed is a practical upgrade for Prusa Mini and MK3S users. The PEI surface delivers reliable results from the first print, and the included hardware simplifies installation.
