Considering the high energy and material consumption, environmental impact of additive manufacturing through FDM has faced significant criticism. For a more sustainable production process, industries require efficient optimization process to lower while retaining efficiency. This study utilizes advanced multi-criteria decision-making (MCDM) methodologies, specifically fuzzy analytic hierarchy (AHP) technique for order preference by similarity ideal solution (TOPSIS), evaluate enhance performance FDM. Focusing on standard thermoplastic materials (e.g., PLA PETG) applications such as functional prototyping, we optimize key parameters layer height, print speed, infill density achieve reductions in usage (20%) waste (15%) compared baseline practices. These findings not only highlight pathway toward greener processes but also lay groundwork future research frameworks, applicable other methods materials.
