Filaments 3D printing

The Robert Bosch Stiftung's "Our Common Future - Pupils, teachers, and scientists research for tomorrow's world" funding program supports the joint research project of school students, teachers, and scientists in the field of sustainability.

In the project itself, the focus is on doing it yourself and researching it. In order to gain an understanding of additive manufacturing and component manufacturing using 3D printing, the students built their own 3D printers from kits and optimized them with the support of the students. In this way they get to know the devices up to the last limit switch.

In the next step, various plastics (e.g. waste from 3D printing, packaging materials) are shredded by type in a shredder and sieved to the appropriate grain size. The particles can then be melted in an extruder and extruded into new filament for 3D printing. In the further course of the project, the pupils reconstruct or scan spare parts in particular and print out the corresponding functional part using recycled filament.
