Our project aims to revolutionize 3D printing with an affordable and eco-friendly printer using post-consumer PET and PP flakes or granules. It addresses cost, filament management, and material sustainability challenges, enabling customized and sustainable product creation. The low-cost, sustainable 3D printer will impact education, industry, and sustainability efforts. It targets students, instructors, entrepreneurs, and sustainability enthusiasts, reducing 3D printing costs, promoting material recycling, and fostering innovation while minimizing plastic waste. Maker Faire Rome participation allows us to share our vision, connect with stakeholders, and demonstrate our commitment to innovation and sustainability. Our presence contributes to advancing accessibility and sustainability in 3D printing.
