Recycling plastic accessories produced by 3D printing used in the context of radiation oncology
The project seeks to gain more basic knowledge of the recyclability of the plastic used in a medical context. By focusing on the particular context of 3D printed boluses for radiation therapy in cancer patients, the initiative will assess the influence of recycling processes and radiotherapy treatments on the structure and properties of the material (PLA, polylactic acid) before it is reused in treatment.
The project has three sub-objectives:
- Determine the extent to which repeated shredding-extrusion-3D printing shaping affects the properties of PLA.
- Determine the influence of radiation treatment (i.e., repeated application of high-energy photons or electrons) and the regular application of cleaning agents on the polymer’s properties.
- Evaluate the combined effect of shaping and radiotherapy treatment on the recyclability of PLA.

Development of a metal-infused recyclable raw material for low-cost 3D printing in the context of circular manufacturing
The project focuses on the development of a new recyclable 3D printing feedstock for low-cost printers.
It explores the unique reaction of nickel and iron with carbon monoxide, which form nickel and iron carbonyl, respectively, to provide an ideal mechanism to recycle the metals, as well as nickel- and iron-based products.
The research aims to develop metal-infused recyclable filaments with high concentrations of nickel and iron carbonyl powders to make functional and resistant metal parts using widespread, low-cost 3D printing processes such as fused filament fabrication.
