SLS Packing Density and Refresh Rate Explained - Formlabs Fuse Material Management

Maximizing Efficiency: Understanding Packing Density and Refresh Rates in SLS Printing
In this video, we dive into the crucial concepts of packing density and refresh rates for SLS (Selective Laser Sintering) printing. Learn how refresh rates impact the minimum ratio of fresh to used powder to maintain material properties. We focus on nylon 12, explaining the benefits of a 30% refresh rate and how the SIFT system automates powder mixing. Discover the importance of packing density-measured as the percentage of fused part relative to total powder used-and strategies to manage and optimize it to reduce costs per part. Practical examples and visualizations will help clarify best practices, as well as software tools to achieve high packing density with ease. Perfect for anyone looking to enhance their SLS printing efficiency.
