3D Aluminum Dual Power Heat Bed (220x220x3mm, Black)

The bed typically consists of a fiberglass PCB with resistive traces on one side and a solid 3mm-thick aluminum plate laminated to the other side. 

Features

• Flexibility: You can use the same heat bed with different power supply configurations by wiring it correctly.
  
• Faster heating: A 24V system provides higher power (watts) for the same resistance, allowing the bed to reach the desired temperature more quickly.
