CADmix II is a second-generation, 2-in-1 device designed to automate the refreshing and mixing of SLS powders. It replaces multiple manual steps — such as sieving, hand mixing, and shaking — with a clean, fast, and fully enclosed process. Using an intuitive touchscreen interface, the operator can start the cycle in seconds. Inside, special buckets with integrated paddles ensure even blending of fresh and used powder, helping users prepare high-quality, homogeneous mixtures for their next print job. Variable rotation control and quiet operation further optimize efficiency and comfort.
