Features: Made of carbon silicon crystal glass build surface provides a strong adhesion in printing and easy to . Once hotbed cools down to room temperature adhesion will be reduced and models can be easily removed. Plate sized 220 * 220 * 3mm (8.7 * 8.7 * 0.1in) can be placed on of existing hotbed surface and be held in place with simple clips. Super flatness fast and uniform heating. As hotbed heats to higher temperatures it provides even more adhesion especially for PLA material. Fits for 220*220mm hotbed and more 3D printer hotbed which can match size of glass plate.
