The ALF-SEM Method
ALF-SEM treats the artificial nail not as a decorative surface, but as a load-bearing architectural system. Developed over more than a decade of practice and published in 2025.
"Geometry is not decorative — it is biomechanical."
— Hanna Khalin, ALF-SEM
Modeling guided by defined geometric references rather than visual estimation.
Material allocated according to how the finished nail will actually be loaded.
Proximal control zone, apex zone, transition gradient, free-edge zone — each with defined parameters.
Apex position is a calibrated structural decision, not an aesthetic preference.
