The MK3 200x200 aluminium heated bed for Prusa 3D printer is an essential component for anyone looking to improve the quality and efficiency of their 3D prints. Made from 3 mm thick aluminium, this heated bed acts as both a heat producer and diffuser, while also providing an optimal surface for direct printing or with borosilicate glass on top.
This model is compatible with MK1, MK2A and MK2B mounting patterns, making it easy to integrate into Prusa 3D printers and Reprap systems. Its design allows for simple and secure installation, with 3.2 mm diameter mounting holes and dimensions of 214 mm x 214 mm, fitting your printer’s needs perfectly.
Key features:
- Material: 3 mm aluminium for even heat distribution.
- Dimensions: 214 mm x 214 mm, compatible with MK1, MK2A and MK2B patterns.
- Voltage: Compatible with 12V and 24V power, adjusting the solder pad connections according to the voltage.
- Resistance: 1.4-1.6 Ohm for 12V and 5.6-6.6 Ohm for 24V.
- Printing surface: Can be used directly or with borosilicate glass for better adhesion and finish.
Typical uses and compatibility:
This heated bed is ideal for users looking to upgrade their Prusa MK2B 3D printers to a MK3 model, improving thermal stability and print quality. It is also compatible with Reprap printers that use the MK1 or MK2A/B mounting pattern, making integration easier without the need for additional modifications.
For 12V power, solder pads 2 and 3 must be connected together to obtain the correct resistance. For 24V, only solder pads 2 and 3 should be used. It is recommended to consult the included technical drawing to check the dimensions and mounting pattern before installation.
Package contents:
- 1 x MK3 200x200 mm aluminium heated bed.
Advantages over previous models:
- Better heat distribution thanks to 3 mm aluminium.
- Compatibility with several mounting patterns, including MK1 and MK2A/B.
- Easy installation and adaptation to different voltages.
Final considerations:
The MK3 200x200 aluminium heated bed for Prusa 3D printer is a recommended upgrade to improve the quality and consistency of your 3D prints. Its robust and versatile design makes it a reliable choice for advanced users and hobbyists looking to optimise their equipment.

Customer Questions & Answers
What are the advantages of using a 3 mm aluminium heated bed compared with PCB alternatives or unheated beds?
3 mm aluminium provides better heat distribution thanks to its high conductivity, resulting in more evenly heated print surfaces and less part warping. Compared with PCB beds, it is more rigid, robust and less prone to damage from handling. However, it adds weight and may require a stronger mounting system on lighter printers.
What compatibility does the MK3 heated bed have with 3D printer models and existing controllers?
The 214 x 214 mm hole pattern and 3.2 mm diameter is compatible with MK1, MK2A/MB and most Prusa clones, but it is recommended to check the exact dimensions of the printer and bed carriage. In terms of electronics, it supports 12V and 24V systems, but requires a power supply capable of delivering between 7.5 and 10 A (12V) or 4 to 5 A (24V).
What are the recommendations for safe electrical installation considering the two possible operating voltages?
For 12V, a bridge must be soldered between pads 2 and 3 to ensure the correct resistance (1.4-1.6 Ω); for 24V, no bridge, using only pads 2 and 3 (5.6-6.6 Ω). You should check polarity, insulate the connections properly and, where possible, include a protective fuse suitable for the expected current draw.
Are there any thermal or mechanical limitations for prolonged jobs or high-temperature materials?
The typical safe operating range of the MK3 is between 20 °C and 120 °C. For special materials requiring more than 110 °C on the bed, it is recommended to monitor with thermocouples and never exceed 130 °C to avoid electrical overload or damage to the hotbed insulation. Aluminium withstands thermal cycles well, but the connection wiring can degrade if it is not secured or ventilated properly.
What maintenance or calibration does the MK3 bed require to ensure stable long-term performance?
It is recommended to periodically check the soldered electrical connections for loosening or oxidation, clean the print surface with compatible products after each use, and recalibrate manual or assisted levelling whenever adhesion problems are detected. It does not require lubrication or moving parts.
Is this heated bed compatible with Prusa MK2B printers?
Yes, the MK3 200x200 heated bed is compatible with the MK2B mounting pattern, making it easy to install in Prusa MK2B printers.
Can I use this heated bed with 24V power?
Yes, this heated bed supports 24V power, but solder pads 2 and 3 must be connected according to the instructions to get the correct resistance.
Can I print directly on the aluminium bed?
Yes, it is possible to print directly on the aluminium surface, although for better adhesion it is recommended to place borosilicate glass on top.
What is the main difference between the MK2B and MK3 beds?
The main difference is the aluminium thickness (3 mm on the MK3), which improves heat distribution and compatibility with different mounting patterns.
What should I consider when installing it in a Reprap printer?
You should check that the mounting hole pattern matches MK1, MK2A or MK2B and follow the solder pad connection instructions for the correct voltage.
