This study investigates the compression behaviors of body-centered cubic (BCC) lattice structures with three different constituent materials, i.e., polylactic acid (PLA), AlSi10Mg and polyamide 12 (PA12), fabricated by fused deposition modeling (FDM), selective laser melting (SLM) and multi-jet fusion (MJF) techniques, respectively. The numerical models of finite element analysis (FEA) with beam elements and isotropic hardening material constitutive law are built to simulate different BCC lattic...

Channel-type segregation is one of the defects in aluminum casting technology, particularly in the direct chill (DC) process, having a significant influence on the cast quality. Nevertheless, the formation mechanism of three-dimensional (3D) channel-type segregations remains poorly understood. In order to clarify the formation mechanism of defects of this type, we conducted a 3D numerical simulation of the DC casting process of an Al-Mg alloy billet considering the melt flow, heat and mass trans...

The goal of this article is to investigate the printability of ethyl cellulose, a biomass derived polymer, using a custom-modified direct ink writing (DIW) printer. Ethyl cellulose is widely used as a thin-film coating in controlled-release vitamins and medical pills as well as a thickener in the food, cosmetics, and other industries, making it an attractive candidate biopolymer for 3D printing. In this work, ethyl cellulose was dissolved in an alpha-terpineol solvent at different solid contents...

Scientific articles have long been the primary means of disseminating scientific discoveries. Over the centuries, valuable data and potentially groundbreaking insights have been collected and buried deep in the mountain of publications. In materials engineering, such data are spread across technical handbooks specification sheets, journal articles, and laboratory notebooks in myriad formats. Extracting information from papers on a large scale has been a tedious and time-consuming job to which fe...

Two alloys containing different Mg contents have been used to study the combined effect of stirring and oxidation on microstructure and ductility. The results show that intensive stirring can sufficiently disperse the α-Al particles and enable better liquid feeding during solidification and consequently reduce the porosity. The morphology of the oxides is determined by the amount of both Mg and stirring. With lower Mg content, the oxides present as oxide films, which can be broken up during stir...
