Specification Brand : POLISI3D BulletPoint1 : Material: Copper. The size is 20x18x10mm. BulletPoint2 : This copper-alloy is very temperature resilient, and will not start to soften or anneal until way beyond 500°C, making it perfect for the high-temperature printing. In addition to high temperature performance this Block have an advanced nickel based plating BulletPoint3 : Copper has more than 3x the thermal conductivity of brass, and the copper alloy we use has been hardened and treated to reduce the oxidation that occurs in copper at high temperatures. The higher thermal conductivity will also slightly increase your heat-up times, and can provide tighter temperature control.
