Features Thermal insulation: the surface is covered with a layer of heat-insulating cotton, which makes the temperature rise faster and maintains the temperature balance at all times, without the need for tearing. Stable performance: the circuit board heating table is integrated into the aluminium plate, which leads to better heating stability and stable performance. BETTER PRINTING: You don't have to worry about deformation of the printing edges, because this aluminum hot bed can provide better printing results for 3D printers. Applicable models: with a size of 310 x 310 x 3 mm, this heated bed is suitable for CR 10 and other 3D printer models. Fine surface treatment: the hot bed has a full gold plating process, which has a longer service life than the tin spray plate. Specification: Item Type:3D Printer Hot Bed Material: aluminium plate.
