Introduction to Tree Supports in 3D Printing
Tree supports represent an advanced approach to handling overhangs in the 3D printing process. These innovative supports replicate natural tree structures by extending upward organically, reducing the number and size of contact points. This not only facilitates easier support removal but also significantly reduces surface imperfections, saves material, and enhances the overall print aesthetics.
