PhD and Principal researcher: 3D printed prostheses for low- and middle-income countries

In 2018 Merel started a feasibility study on how a 3D printing could be of added value in a resource-limited healthcare setting and has been leading the project since. In 2020 she graduated doing researching into 3D printed lower leg prostheses. At the moment, she is doing further research into 3D-printing prosthetic aids as a PhD Student.



Trhoy is the resident physiotherapist at Masanga hospital. He helps people learn to use their prostheses again though walking exercises. Together with Idrissah, he also does follow-ups with the patients.



Idrissah is just like Throy a physiotherapist at Masanga Hospital but also focusses on research.

In memoriam of Wouter Nolet, Doctor International Healthcare and Tropical Medicine.


In autumn 2019, M. van der Stelt and L. Brouwers conducted a successful crowdfunding campaign in collaboration with the Dutch Albert Schweitzer Fund (NASF); collecting 15,000 Euros. With this amount, we financed an MPP Solar off-grid inverter combined with two batteries to prevent power changes and outages of the printer. We support local employees with a small salary contribution for their indispensable work, and we donated a car to the Masanga Medical Research Unit.


We obtained an internship allowance for students from the University of Twente and Delft to cover the cost of ethical approval and transport.

Ultimaker (Ultimaker BV, Geldermalsen, the Netherlands) gifted the 3D-printer as well as printing materials. Shining 3D (Einscanner Pro Plus, Shining 3D Technology, Hangzhou, China) gifted a 3D-scanner. To both companies, we express our gratitude.

We would like to thank all the participants and the Masanga staff who helped manufacture the prostheses!
