From April 17–19, 2026, the “8th National Startup Day for Students (SV_STARTUP 2026)” was held at the Banking Academy. This year’s competition attracted 880 startup projects from students across educational institutions nationwide, with 135 outstanding projects selected for the final round.
After multiple evaluation rounds, the project “Refil 3D – Design and Manufacturing of a Recycling Machine for Failed 3D Printing Plastic and PET Bottle Waste into 3D Printing Filament” won Third Prize overall.
ReFil3D is a filament recycling machine integrated with a web-based management platform, allowing real-time monitoring of temperature, filament output, and energy consumption. The system is capable of converting failed 3D printing materials and PET plastic waste into standard-sized 3D printing filament through a closed-loop process. It is user-friendly and suitable for schools, laboratories, and small-scale 3D printing workshops.
The project aims to reuse plastic waste, reduce material costs for 3D printing, and contribute to environmental protection. It can reduce material costs by 40–60%, utilize readily available plastic waste, and support circular economy models. Beyond economic benefits, the product also supports STEM education, technical research, and the development of green startup initiatives.
