Learn to recreate the 3D printed Thallus sculpture using Grasshopper and Kangaroo Physics in this 25-minute tutorial. Explore the differential growth algorithm that creates an expanding curve, and discover how to modify its behavior to form structural connections suitable for 3D printing. Follow step-by-step instructions covering topics such as segment length, avoiding crossings, angle setting, tapering, and simulation. Gain insights into creating complex, self-supporting patterns for 3D printed sculptures through this hands-on Grasshopper tutorial.
