Take the controls.
Run a real engineering trade-off from this field. Move the sliders, watch the model react in real time and beat the challenge.
What you will be able to do
Analyse the anatomy and biomechanics of the residual limb.
Compare total contact and selective weight-bearing socket designs.
Capture the shape of the residual limb with 3D scanners.
Digitally modify the socket model with CAD software.
Manufacture sockets by milling or 3D printing.
Carry out static and dynamic alignment of the prosthesis.
Evaluate the socket through simulation and user trials.

How you'll learn
100% online training on the SEIUM campus, with downloadable material, recorded classes and an assigned technical tutor. There are no fixed timetables: you progress at your own pace within the intake, so it fits around your job.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is Rodin4D, Canfit (Vorum), Autodesk Fusion 360, Autodesk Meshmixer and Ansys Mechanical, in free, academic or evaluation versions. Testing is studied through real procedures for 3D scanning of residual limbs, manufacture of check sockets by milling and 3D printing, and dynamic alignment in a gait laboratory. Assessment is continuous by module, plus the final integrative project.
Standards covered: ISO 10328, ISO 22675, ISO 22523, Regulation (EU) 2017/745, ISO 13485, ISO 10993-1, ISO 8549-1.
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.
