Development of a 3D printed patient specific Ankle Foot Orthosis

Patients diagnosed with drop foot syndrome experience difficulties creating enough clearance during walking, resulting in stumbling over very small obstacles. An Ankle Foot Orthosis is an orthopaedic aid which limits the plantar flexion of the foot, providing a safe walking gait for the patient. Currently, these AFOs are vacuum formed over a...

Intent-Based Material Extrusion 3D Printing: Moving from process-driven to intent-driven 3D printing

The graduation project is carried out as a collaboration between the Delft University of Technology and Ultimaker. Ultimaker B.V. is a 3D printer company located in Geldermalsen, The Netherlands. Users of 3D printers are presented with a multitude of action possibilities. However, these action possibilities are not yet translated into easy to...

e-AD: enhanced attachment device: A new attachment for trans-humeral amputees between a myoelectric prosthesis and a bone anchored implant system

The goal of Integrum is to improve the life of amputees. They do so by providing the OPRA (Osseointegrated prosthesis for the Rehabilitation of Amputees), bone-anchored implant systems for prosthetic attachment: a prosthesis can be mounted on a percutaneous abutment (‘pin’) coming from the residual limb. One of the latest developments of...

Draw in the air: Redesign of 3D pen

3D pen functions similarly to 3D printers or glue gun. It quickly melts and cools coloured plastic to create rigid and freestanding structures, which is potential to be a perfect tool for architects, designers and all the creative experimenters. The project aimed to redesign the 3D pen that optimise the experience of creating three dimensional...

The development of a hybrid manufacturing system that combines multimaterial 3D-printing with silicone casting for the development of soft robotic parts

This master thesis discusses the development of a hybrid manufacturing system that combines multi-material 3D-printing with silicone casting. The parties involved in this project were soft robotics research group at the University of Technology Delft and Ultimaker. Ultimaker served an advisory role and helped in providing the needed hardware....
