ABSTRACT

Three-dimensional (3D) printing is a novel product creation process. Although it is convenient for human life, it generates large amounts of greenhouse gases and air pollutants, which cause global warming and adversely affect human health. This study used fusion deposition molding technology as an example to investigate the multi-target optimization results of mechanical properties (dimensional accuracy and surface roughness), manufacturing costs, CO2 emissions (electricity consumption generation), and air pollution (PM2.5), which represent the quality of manufactured products to achieve a win-win situation for both economic and environmental aspects in the process of mechanical manufacturing. The multi-target optimization results obtained by desirable analysis are without heat bed and fan, 185°C of extrusion temperature, 10 mm/s of printing speed, 50% filled Tri-hexagon pattern, lying flat on the printing platform, two-layer shell with 0 mm height per layer, two outer shells with a layer height of 0.2 mm each, and blue filament.
