I Built an AI That Slices Your 3D Printing Support Waste by 40%

The Moment I Knew Something Was Wrong Two weeks ago, I pulled a 12-hour print off my build plate. The model was beautiful. And 35% of the filament I paid for was sitting in the trash - twisted, snapped, and sanded-off structures that had done their job and become instant waste. I'd been printing for years. I knew s were "necessary evil." But then I started noticing something: every slicer on the market - Cura, PrusaSlicer, OrcaSlicer, Bambu Studio - uses the same algorithm to decide where s go. A simple angle threshold. If a face is steeper than 45°, slap s everywhere beneath it.
