        abstract = {3D printing technology is widely used in educational institutions for making models and prototypes. However, the quality of 3D printing filament supplied to schools is sometimes poor, which causes the filament to become brittle after long storage. Brittle filament breaks easily and becomes unusable, resulting in material wastage and financial loss. In addition, during the 3D printing process, extra material used as support structures also becomes waste. At the same time, plastic bottle waste is increasing continuously in the environment due to its slow degradation rate.
To solve both problems, the Bottle-2-Build project proposes a system that converts waste plastic bottles and discarded filament into reusable 3D printing filament. The plastic bottles are cut into thin strips, melted, and passed through a specially designed mechanism to produce filament of 1.75 mm diameter suitable for standard 3D printers. The developed filament can be reused for printing new objects.
This project provides a low-cost, eco-friendly, and sustainable solution for filament production while reducing plastic pollution.},
