In 3D printers, suboptimal cooling and cure rates can negatively affect the manufactured parts and components. By optimizing a 3D printer’s design, we can ensure the quality of the printed objects. One research group used simulation to analyze the cooling process and the resulting glass-transition temperature of the polymer in a 3D printer. Let’s look at how they modeled the extrusion of acrylonitrile butadiene styrene (ABS) from a 3D printer that uses fused-deposition modeling (FDM®).
