As part of BeSoGreat, the University of Applied Sciences Kufstein Tirol is working on the development of 100% biodegradable products. The focus is on the investigation of the innovative material BSG-BC (BeSoGreat-Biocomposite) and its optimisation for the binder jetting process.
What is binder jetting?
Binder jetting is an additive manufacturing process in which three-dimensional objects are built up layer by layer from powdered material. The process begins with the subdivision of a CAD model into individual layers. Powder is applied layer by layer and a binder is precisely introduced at the desired points to form the structure of the component. After the printing process is complete, the component is removed, cleaned and – depending on the material – further processed by post-processing such as sintering or infiltration.
Research with the ‘Tabletop’ experimental plant
At the University of Applied Sciences Kufstein Tirol, in cooperation with J. Zimmer Maschinenbau GmbH, binder jetting is being intensively researched using the ‘Tabletop’ experimental plant. In the course of the BeSoGreat project, the BSG-BC (BeSoGreat-Biocomposite) is being tested on this machine and parameters for processing are being developed.
What is special about the research is the use of a wide range of different binders, including gelatine and starch. The aim is to develop fully biodegradable products. Since these are novel materials, the printing parameters are tested and adjusted step by step to achieve optimal results.
Focus on sustainability
The results of this research not only contribute to the further development of the binder jetting process, but also open up new perspectives for sustainable and environmentally friendly production processes.
