🔥 MK2B PCB Heatbed Dual 12V 24V

♨️ Stable, Reliable & Uniform Heating for 3D Printers

The MK2B is one of the most widely used PCB heatbeds in the RepRap and Prusa ecosystem. Designed for PLA, ABS, PETG, and more, it ensures consistent thermal performance and reduces warping during printing.

With a heatbed installed, your ABS and PLA prints achieve optimal results because the heated surface prevents parts from cooling too quickly.

🛡️ Thermal & Electrical Performance

• 🔥 Prevents warping by keeping print surfaces warm
• 🧽 Must be degreased before use and ideally covered with Kapton tape
• 🔧 Includes a dedicated solder pad for 24V configurations

🌡️ Temperature & Heating Times

• At 12V: heats to 90°C in ~8 minutes
• At 24V: heats to 120°C in ~6 minutes

🔥 Recommended Printing Temperatures

• ABS: Best performance at 110°C bed temperature
• PLA: Optimal at 50°C–60°C

🔌 Electrical Characteristics

• Nominal resistance: 1.3Ω – 2Ω
• Power supply requirement: Ensure the printer PSU has at least 10A available

📏 Robust & Easy to Integrate

Made from FR4 PCB, the MK2B offers low thermal expansion and long-term durability. Mounting holes follow the Prusa i3 standard, while clear solder pads simplify wiring.
