Abstract Material extrusion, also known as fused filament fabrication, is one of the most popular additive manufacturing techniques due to its lower cost and ease of handling. However, parts produced by material extrusion have relatively poor mechanical performance, dimensional accuracy and thermal performance as compared to parts produced by subtractive manufacturing due to high void content. Previous studies have suggested print path deviation as the cause of these voids, but no attempt has yet been made to characterise these deviations. In this study, we propose a method to assess print path deviation for material extrusion that may reduce the formation of voids in printed parts. Geometric features including straight paths, various angled corners and curves of varying radii are printed at different print speeds using an open-source printer and then imaged under a microscopic. The deviation in print path centroid and width is classified as being a combination of systematic and stochastic deviations. Systematic deviation is determined by the difference between the mean of the actual print path and the ideal print path sent to the printer by the user. Stochastic deviation represents the randomness across print samples and is given by the root mean square deviation. The relationship between stochastic deviation between any two points along the print path is determined by a correlation coefficient. The results show that both print speed and different geometric print features affect the amount of deviation in the print path. In the case of correlation of the stochastic deviation along print paths, geometric features are found to have a much greater effect than print speed. The proposed method provides a low cost and highly transferrable technique to characterise the print path deviation within material extrusion parts with respect to varying printing parameters. An accurate understanding of local print deviations within a part plays a major role in the analysis and topology optimisation of 3D printed parts and gives the ability to assess the print quality and identify the root cause of print deviations, thus reducing voids and improving mechanical performance, dimensional accuracy and thermal properties of the printed part.

Abstract This research work presents the investigation of H13 tool steel powder in the production of parts characterized by complex features via selective laser melting. The authors proposed a benchmark geometry with 40 mm nominal height, self-supported overhanging structure and internal channels. To investigate powder printability and process capabilities, an experimental campaign was designed as a function of laser power, scan speed and hatching distance. Full dense parts exhibiting 99.92% internal density have been achieved by imposing a laser power equal to 150 W, a scan speed equal to 500 mm/s and a hatching distance equal to 120 µm, while high geometrical accuracy in terms of no material drops along sample edges and low-dimensional deviations of the realized sloping surfaces (i.e., + 0.23° and − 0.90° for nominal 35° and 40° overhang, respectively) has been achieved for 150 W, 1000 mm/s, and 100 µm. Findings open the way to use SLM technology in the design of advanced cutting tool solutions.
