Extra-wide deposition in extrusion additive manufacturing: A new convention for improved interlayer mechanical performance. Additive Manufacturing, 61, Article 103334. https://doi.org/10.1016/j.addma.2022.103334

Recent studies have contested long-standing assumptions that mechanical anisotropy is caused by weak interlayer bonding and demonstrated that microscale geometry (the groove between extruded filaments) is the major cause of anisotropy in extrusion ad...

Investigation on corner precision at different corner angles in material extrusion additive manufacturing: An experimental and computational fluid dynamics analysis (2022)
Presentation / Conference Contribution
Mollah, M. T., Moetazedian, A., Gleadall, A., Yan, J., Alphonso, W. E., Comminal, R., Šeta, B., Lock, T., & Spangenberg, J. (2022, July). Investigation on corner precision at different corner angles in material extrusion additive manufacturing: An experimental and computational fluid dynamics analysis. Presented at 2022 International Solid Freeform Fabrication Symposium, University of Texas at Austin

This paper investigates the influence of different corner angles on microscale geometry in material extrusion additive manufacturing. Polylactic acid (PLA) was 3D-printed with corner angles of 15°, 30°, 45°, 60°, 75°, 90°, and 135° using Bowden and D...
