Dimensional Accuracy of a Hole Diameter Produced by Material Extrusion

What is it about?

Three-dimensional printing technology has become one of the key areas of Industry 4.0, as it allows complex geometries to be produced on site without wasting material. However, there are still shortcomings in terms of product quality and cost. Because dimensional accuracy is one of the most important parameters for product quality, researchers are working to improve dimensional accuracy. However, most studies have focused on the dimensional accuracy of holes in the z-axis. Because additive manufacturing is a layer-by-layer manufacturing method, the dimensional accuracy of holes in the x- and y-axes will be very different from that of holes in the z-axis. In this study, the effect of printing parameters on the dimensional accuracy of holes of different diameters and axes produced by additive manufacturing from different materials was investigated.
