... insufficiently understood. This study aims to investigate the effect of print speed on the mechanical performance of polylactic acid components produced using a commercial pellet-based system (Tumaker NX Modular), with emphasis on identifying strength–ductility trade-offs. Design/methodology/approach Five...

.... The purpose of this study is to enhance the mechanical performance of material extrusion ( MEX ) structures by overcoming the limitations of conventional grid infill patterns. Design/methodology/approach A strain energy-based framework is developed to optimize the printing path by constructing U* value...

...Sermet Demir; Caner Yüksel Purpose This study aims to investigate the mechanical performance of bi-adhesive single-lap joints fabricated using fused deposition modeling ( FDM ) with polylactic acid adherends. By combining a brittle and a ductile epoxy adhesive in different sequences and area...

... have been used to determine the process parameters that provide the best results. In addition, the process’ impacts on the dimensional accuracy, quality, hardness and mechanical performance of the treated parts under static bending and fatigue testing have been quantified and compared to the untreated...

...Heena Noh; Kijung Park; Hyun Woo Jeon Purpose As newer high performance polymers in mechanical properties become available for material extrusion-based additive manufacturing, determining infill parameter settings becomes more important to achieve both operational and mechanical performance...

...Weiwei Wu; Zhouzhou Wang; Shuang Ding; Aiping Song; Dejia Zhu Purpose The effects of infiltrant-related factors during post-processing on mechanical performance are fully considered for three-dimensional printing (3DP) technology. The factors contain infiltrant type, infiltrating means...
