Modern orthopedic shoemaking is moving from the workbench to the workstation. In this one-hour session, Martin Jaeger will show how he uses Rhino 8 and his own custom-built Grasshopper scripts to transform a 3D foot scan into a fully individualized shoe last with integrated orthopedic footbed correction.
Instead of relying on manual plaster casting and hand-finishing, this session demonstrates a parametric, repeatable pipeline that keeps every last precisely matched to the patient's anatomy while dramatically reducing production time.
What you'll see
- How a raw 3D foot scan is cleaned, aligned, and prepared as a usable base geometry.
- Building a parametric last-generation workflow with custom Grasshopper components.
- Applying orthopedic corrections directly onto the last geometry using Rhino 8's native modeling tools.
- Verifying and controlling dimensions and measurements with Rhino 8's tools throughout the process.
- Exporting production-ready geometry for milling or 3D printing.
Who this is for
This session is designed for shoemakers, shoe designers, orthopedic shoemakers (Orthopädieschuhmacher), and orthopedic technicians (Orthopädietechniker) who want to bring digital, parametric workflows into last-making—no prior Grasshopper experience required.
Speaker bio
Martin Jaeger is a master orthopedic shoemaker (Orthopädieschuhmachermeister) who learned the craft from the ground up.
