Fused Deposition Modelling (FDM) is a popular additive manufacturing technique that may be used for quick prototyping and manufacture. The current study was focused on assessing the process sustainability to ensure lightweight construction with low environmental impact and printing time, in light of the growing trend of sustainable manufacturing. Having extensive applications in electronics, aviation, automobile application, etc. Polyamide 6 reinforced with 30% glass fibre (PA6GF30) was used as the test material. A Design of Experiments (DoE) using the Taguchi method composed of L9 array tests was conducted by varying four different printing parameters namely wall thickness, fill density and feed rate. During the test, three critical metrics of sustainable manufacturing (energy, power, and carbon emissions) were measured. The DoE findings were subjected to analysis, which demonstrated that the printing parameters in question had a considerable impact on the specified sustainability metrics. Finally, optimal printing parameters for the FDM technique are recommended to assure long-term printing
