The “Impossible” Geometry: A Deep Dive into Soluble Supports
Every 3D printing enthusiast learns the “45-Degree Rule” on day one. It is the fundamental law of Fused Deposition Modeling (FDM): you cannot print in thin air. If a part of your model hangs over empty space without anything underneath it, gravity wins, and the plastic droops into spaghetti. To fight gravity, we use supports—scaffolding…
