SustainaPrint: Making the Most of Eco-Friendly Filaments
summary
SustainaPrint combines finite element stress simulation with material-aware assignment to replace only low-stress regions with recycled or biodegradable filament while reinforcing high-stress zones with virgin PLA, outputting dual-extruder prints ready for an Ultimaker S5. A companion low-cost at-home mechanical testing toolkit measures filament strength (recycled PLA can lose ~50% tensile strength after cycles) and the pipeline is validated on five functional objects and five primitives with Instron tests, showing large load-capacity gains and near-virgin performance.
