  • Prototyping a standalone system that recycles used plastic bottles in order to use the material for 3D printing purposes

6 step process of how a plastic bottle is turned in to filament that is used in a 3D printer

We are focusing on creating a single standalone system while integrating the three main components for speed, accuracy and least amount of lead time. It will achieve delivery of product with cost and energy effectiveness as well as adaptability in handling wide range of recyclable plastic products. We also aim towards increasing flexibility in extruding multiple polymers materials and printing with them, and controlling multiple motors in sync and interfacing sensors for minimum human input and better operation. 

The system will have individual components like a shredder for cutting the plastic bottles, a filament extruder and a feed mechanism for the shredded material to be transported to the hopper of the extruder, filament collection and retrieval system and finally a 3D printing system.
