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.

• Higher flow! Increased surface area contact with the filament boosts the volumetric flow rate significantly compared to our stock Prusa brass nozzle
• Reduce print times and increase nozzle lifetime
• Durable against abrasive materials such as carbon-fibre
• Benefit from non-stick properties of the custom E3DLC ™ coating

• Sizes: 0.4mm – 0.6mm
• Input diameter: 1.75mm
• Max temperature: 300°C
• Compatibile with Nextruder
• High flow ready
• Abrasion resistance

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

Powder coating directly on metal makes it very hard to damage this build plate. If a heated nozzle crashed into it, the metal can dissipate the heat. Powder coating also gives the surface a distinct textured look that will be visible on your prints. The textured surface hides most of the mechanical damage caused by tools. Only the top of the small bumps can be scratched, which will not imprint on the bottom of the model. 

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

If you love modifying your 3D printer, adding new features, and tweaking it to your liking, our accelerometer module for printer developers and modders 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 modded 3D printer operates with maximum efficiency.

Our printers come from the factory with pre-configured, optimized 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 modders and developers, installing the accelerometer on the printer and using it is very easy.

Compatible with: MK4, MK3.9, MK3.5, MK4S, MK3.9S

The GPIO module is an excellent tool for modders, hackers, and tinkerers who love adding new features to their 3D printers. It connects to the I2C port on the xBuddy board of your Original Prusa MK4/S, MK3.9/S, or MK3.5/S, enabling you to control and receive input from external devices.

You can create a trigger for your camera to capture precise timelapse photos, control external LED lighting to alert you with different colors when the printer has finished printing or requires attention, adjust fan speed, control servos, activate enclosure functions, and much more—you name it! All you need is a connected GPIO module and a custom G-code command, which can be executed at a specific layer, at the start or end of a print, or during other events. You can set all commands directly in PrusaSlicer.

You can also integrate a button or macro keyboard and assign each key to execute specific G-code scripts, stored in the printer’s USB drive, allowing you to control various printer functions, such as setting the printer to a ready state, managing the print, adjusting temperatures, or executing other actions.

Compatible with: MK4, MK3.9, MK3.5, MK4S, MK3.9S

The MK4->MK4S Upgrade Kit contains everything you need to fully upgrade your stock MK4 3D printer to the new MK4S.

The upgrade is supplied as a kit - you need to assemble it yourself. Before you order the upgrade, please check which xLCD your printer came with. This upgrade is for the new version of xLCD.

Every Original Prusa 3D printer receives long-term support for years after launch. Not just small bugfixes, but major firmware and hardware upgrades that bring useful new features. And MK4 is no exception.

Compared to the Original Prusa MK4, the MK4S brings the following innovations:

• New high-performance 360° cooling system
• High-quality high-flow nozzle as standard
• Native iOS/Android Prusa app for iOS and Android with easy Wi-Fi setup with an NFC tap
• Improved print speed
• Improved print quality
• New parts printed from Prusament PC Blend Carbon Fiber or injection molded
• Optional accessory: GPIO hackerboard
• Optional accessory: accelerometer for printer modders

The Prusa Nozzle ObXidian is a high-quality nozzle designed specifically for Nextruder.

The Original Prusa MMU3 is our latest solution for printing with up to five filaments at the same time with high speed and low waste. As an add-on for the Original Prusa MK3.9S + and MK4S, it enables automatic switching between loaded materials. MMU3 is fully supported in PrusaSlicer by an easy multi-material painting tool, and it offers efficient and filament-saving color printing to everybody.

An optional add-on that allows your single-extruder printer to print with up to 5 colors (materials) at the same time. The MMU3 contains five filament insertion points. Load up to five colors of your choice, slice the object in PrusaSlicer and start the print. The system automatically selects filament using the selector, loads it into the extruder and the printer starts printing. When it’s time to change the color or material, it also happens automatically.

The high-flow nozzle in the MK4S allows for much faster printing. However, when using the MMU3, the standard nozzle makes more sense. While the MMU3 works fine with a high-flow nozzle, the increased volumetric flow results in higher filament waste during printing. In other words, the MMU3 delivers the best performance, the same speed and the highest efficiency (lowest waste) when combined with the standard nozzle in the MK4S.

This product is supplied as a kit. Assembly is required

Prusa CORE One+ Conversion kit contains all parts you need to transform your Original Prusa MK4S into the fully enclosed CoreXY 3D printer, the Prusa CORE One+. This kit is compatible with the MK4S only!

The silver PSU is not compatible with the conversion kit.

Transform your Original Prusa MK4S into the brand new, fully enclosed CoreXY 3D printer and upgrade your printing experience. Once you’re finished with the assembly, your new printer is going to be not only faster, but it will also take up less space, print larger models and tackle even demanding filaments like PCCF or Nylon without warping. In the Conversion Kit, you will find everything you need to perform the entire process and end up with the Prusa CORE One+ without any compromise.

The Prusa CORE One+ utilizes many proven parts from the Original Prusa MK4S. This is why it is possible to convert your existing 3D printer into the new Prusa CORE One+. You can easily reuse your current print sheets, hotends, nozzles, and many other parts.
