Please note ：After ORDER,please extend 10days shipping time If you need customized size, please contact customer service and provide size drawings, thank you Glad that after more than a month of testing, we finally released the graphite heating plate. We conducted a lot of verification on the heating speed and flatness of the graphite plate, and finally obtained perfect data results. Compared with ordinary aluminum plates, the advantage of graphite build plates lies in their unique thermal expansion characteristics. Aluminum plates expand and deform when heated, but graphite has an extremely low thermal expansion coefficient. This feature allows it to maintain its shape even at high temperatures for a long time. And the graphite plate effectively reduces the thermal resistance between the silicone heater and the spring steel plate, thereby achieving a faster and more stable heating process.
