About this paper
Yefan Zhi, Masoud Akbarzadeh
The authors present a toolpath method that trims unsupported portions of each layer and reconnects shell paths to preserve closed, non-intersecting curves. It enforces a chosen local overhang limit, measured between adjacent layers, rather than addressing global stability. In the Pipe example, area intersection-over-union falls from 0.920 at limit 1.5 to 0.674 at 0.7, showing shape change.
