E3D VariPower Heated Bed with Modulated Power Zones

E3D developed a heated bed that has distributed heated zones so that the heat is distributed evenly to avoid potential warping due to temperature differences. It can reach up to 140 degrees Celsius on 200mm * 300mm print surface. It is very useful if you want to print larger series of multiple parts on entire surface.
It is priced at £45.00.
