| + | **Results** | ||
| + | |||
| + | * Sorting and cleaning the waste are critical steps in order to reduce the difficulties and number of deffects at the end. | ||
| + | * Extruding a new filament from waste is particularly difficult, especially with PETG. The process is very sensitive. | ||
| + | * At the end, we are able to extrude good filament made 100% of waste (without adding virgin material) and with no loss of material properties! | ||
| + | * Because of all these factors, our spools still present some deffects (diameter change, presence of foreign objects) that can clog the 3D printers' | ||
| + | * Now we are working on quality control: detection and correction of the deffect. | ||
| + | |||
| + | The project is still in progress but hopefully we will be able to let students try our in-house filament before the end of 2025. | ||

| + | **How you can contribute** | ||
| + | * As a SPOT user, you already contribute by giving us some raw material. But PLEASE, throw your plastic parts carefully! **PURE PET-G ONLY!! NO GLUE; NO SCREWS, NO INSERTS!!** | ||
| + | * As a Master student, you can contribute by doing a semester project with us! Ask the coach for available projects. | ||
