Investigating Metal 3D Printing of Spare Parts for Re-manufacturing Fuel Injection Pumps

The goal of this graduation project was to investigate if 3D printing could serve as a promising alternative for manufacturing spare parts needed for the re-manufacturing of diesel injection pumps. This project was conducted under the EU ReCiPSS project, along with the support of Robert Bosch GmbH. The proposition was investigated on three...

Enabling the recycling of 3D printed electronics in a circular economy

This thesis describes the research on design measures and new recycling methods to enable the recycling of 3D printed electronics. By looking into methods to release metals from polymer substrate and design interventions to enable predictable fracturing of 3D printed structures in a shredder, a step towards the recycling of valuable metals from...

Shining light on mussel shells: The development of a 3D printed and recyclable material

This master thesis is the result of a graduation project for the Master Integrated Product Design at the TU Delft. The project was formulated as a continuation on research done by Mariet Sauerwein and Zjenja Doubrovski, in which they proved the potential of mussel shells as a material for material extrusion 3D printing. This with the aim of...

Application of 3D printing in Repair

Repair was once a common act. With increased product diversity and complexity, a scarcity and obsolescence of spare parts is making repair increasingly difficult and economically unviable. The result is an accelerated turnover of manufactured goods, which are more often replaced than repaired. As products are discarded, embedded materials and...
