Laser powder bed fusion of Ti6Al4V using low-cost high efficiency 450 nm diode point melting by Alkim Aydin, Erhan Cetin, S. Can Erman, Kamran Mumtaz

“…The grain size of Ti6Al4V samples fabricated using DPM were significantly larger compared to those produced by LPBF (grain size area ∼ x30 larger). Young's modulus of the samples produced via DPM was found to be higher than LPBF manufactured Ti6Al4V, indicating increased stiffness. …”

Strengthening mechanism of particle gradation in 55 vol% SiCp/6061Al composites fabricated by semi-solid hot isostatic pressing by Kun Cheng, Yudong Cao, Yuhan Jiang, Xiangyun Gao, Guizhou Liu, Chunmao Tian, Chao Cai, Yusheng Shi

“…Results show that the SiC11/6061Al (with 40 μm:10 μm ratio of 1:1) sample achieves a high relative density (99.07 %) and demonstrates excellent mechanical performance (ultimate tensile strength of 373.09 MPa and Young’s modulus of 188.62 GPa). Compared to other engineering materials, this composite offers significantly higher specific stiffness and specific strength while maintaining favorable thermal conductivity and a low coefficient of thermal expansion. …”

Enhancing helmet pressure sensing with advanced 3D printed gyroid architectures by Chao Bao, Danielle Jaye Agron, Taeil Kim, Chris Vattathichirayi, Edwin L. Thomas, Woo Soo Kim

“…To address this, we introduce a representative elementary volume (RVE) simulation model to accurately represent the fused layers from the Fused Deposition Modeling (FDM) process. By establishing Young’s modulus of the fused layer at 48.7 % of pure matrix material, we enhance the model’s accuracy to align with experimental data. …”
