Decision

What the current evidence supports

Human editorial judgment · 2026-06-28

Proceed with caution

Why
Open-source, commodity-FDM, support-free pipeline is genuinely useful and reproducible-by-design, but thermal/magnetic off-board actuation, sub-90% shape fixity, and single-lab small-n validation cap it at experimental adoption.
Next
Pilot the open-source Grasshopper/Python rotary slicer on an in-house FDM rig for a non-critical tubular part; assess whether support-free toolpaths, the ~70% material / ~50% time savings, and the 36% nodal-strain reduction reproduce before committing to any design.
