Bachelor's thesis This study aims to upcycle spent coffee grounds by designing a small-scale injection molding machine that produces coffee cups out of spent coffee grounds and polylactic acid. The machine aims to scale injection molding into a smaller form-factor that is portable and compact. The study aims to develop a machine that can produce a single 12 oz. cup in 15 minutes. The evaluation of the machine focused on its efficiency, the quality of the cups it produced, user-friendliness in terms of operation and maintenance, and its safety standards. An economic viability study was carried out to evaluate the machine's cost-effectiveness. The development process included interviews, surveys, literature reviews, calculations, simulations, and experimental trials. Findings indicate that the coffee cup molding machine effectively meets the required specifications, integrating key components such as heating elements, an injector, and a mold. It can produce 12 oz. cups within 15 minutes and operates within the target temperature range of 220 to 240°C for melting the mixture. Crucial parts like the heating system, injector, mold, and fans were successfully implemented. According to the economic viability analysis, the machine presents a cost-effective solution with a high return on investment and a short payback period of approximately.
