Orthopedic Insole Reverse engineering + Lattice Design + 3D Printing

Reverse Engineering an Orthopedic Insole | CAD Reconstruction + Lattice Design + 3D Printing (TPU)

Here is a a complete example of Reverse Engineering applied to an orthopedic insole; starting from a 3D scan that generated a poly mesh STL file, we use Geomagic Design X to reconstruct a highly accurate CAD model. This process demonstrates how scanned data can be transformed into a usable solid model, an essential workflow for anyone involved in digital orthotics or custom medical device design.

Once the CAD reconstruction is complete, the model is exported in STEP format and brought into Altair Inspire, where we add an advanced lattice structure with variable density. This technique not only reduces weight but also enhances the flexibility and cushioning properties of the insole (key factors for orthopedic comfort and performance).

The final design is then prepared for 3D printing and produced using HP Multi Jet Fusion technology with flexible TPU material. TPU (thermoplastic polyurethane) offers the perfect balance between strength and elasticity, making it ideal for wearable medical applications like insoles, braces, and other adaptive components.
