Features GOOD INSULATION EFFECT: The surface of the 3D printer aluminum substrate is covered with a layer of insulation cotton, which can heat up faster and maintain the temperature, and maintain the temperature balance every moment without tearing off. FINE SURFACE TREATMENT: The hot bed use the full plate gold plating process, the cost is much higher than the spray tin plate, more durable. STABLE STRUCTURE: Circuit board heating table and aluminum substrate combined into one, bring better heating stability, and stable power. WILL NOT WARP: Do not worry about the problem of printing warping, aluminum hot bed can provide better print quality for 3D printers. APPLICABLE MODEL: Aluminum hot bed is suitable for Anet E16 A8PLUS and other models or other brands of 3D printers.
