Additive circular manufacturing meets disassembly and repair-friendly product design
In order to address the current hot topic of "circular value creation" and make it concretely demonstrable, the concept of additive circular manufacturing will be implemented as part of this project in order to provide prototypes for further knowledge transfer of principles of product design suitable for disassembly and repair. The project thus illustrates two key strands of circular value creation:
The aim of Additive Circle is to design a recycling production process using 3D printing as an example. Misprints or print objects that are no longer required are not thrown away, but are instead reprocessed into printing filament and reused for new 3D prints. In a further step, it will be investigated whether this process can be extended to other suitable plastic products that are at the end of their actual use phase or plastic waste. This circular production process will primarily be used to produce new components or demonstrators for product design suitable for disassembly and repair. Printing takes place on a special printer, which is essentially produced by 3D printing and whose spare parts can themselves be produced again by 3D printing using the circulating filament.
Objective: the Additive Circle
Additive Circle therefore promotes the sustainable and resource-efficient production of components and helps to communicate the principles of product design that is suitable for disassembly and repair. It also presents the concept of a circular economy in a tangible and easy-to-understand way and provides a basis for future projects on circular value creation and product design that is suitable for disassembly and repair.
