Before being utilized in advanced engineering applications, lattice structures produced by 3D printing require a detailed understanding of how various print parameters affect their mechanical performance. Kevano Danendra, S.T., conducted his final project at the Solid Mechanics Laboratory, examining the impact of 3D print parameters on the mechanical properties of strut-based lattice structures. His research offered crucial insights for optimizing 3D printing settings, enhancing structural efficiency, and contributing to more robust design possibilities. This study paves the way for future advancements in additive manufacturing and material engineering. 🔬🛠️ Kevano’s role as an ex-MBP Lead Laboratory Assistant at Institut Teknologi Sepuluh Nopember underlines the importance of meticulous experimentation and analysis in driving forward innovations within the field of mechanical engineering. #Engineering #LatticeStructure #Sandwichbased #ITSSurabaya #SolidMechanics #MechanicalEngineering

For my PhD, I am working on printing new walls using aluminum Wire Arc Additive Manufacturing (WAAM) and employing new techniques to mitigate the residual stresses. The image is for a wall that was recently printed. This could not have been achieved without the guidance of my mentor and supervisor Dr.Mohamed Abdelaziz, PhD. The work was done at Additive Manufacturing Centennial Lab (AMCL)-AUC. Feel free to share your valuable insights on the topic! #additivemanufacturing #WAAM #Aluminum #PhDResearch #3dprinting #sustainablemanufacturing #wirearcadditivemanufacturing #metal3dprinting #metals

I predict we will be 3D printing the hulls and superstructures of aluminum vessels in the not so distant future. The use of such innovative technologies as being pioneered by PhD Candidate Sara Soliman shall revolutionize shipbuilding and ultimately reduce construction costs. Keep in mind that a 3D printer doesn’t get tired, nor does it complain. With the right human (or AI) oversight it can print, print and print… 24 hours a day, 7 days a week. I wish Sara and her mentor Dr. Mohamed Abdelaziz, PhD fair winds and following seas as she seeks to advance aluminum 3D printing and additive manufacturing. #Innovation #3Dprinting #additivemanufacturing #shipbuilding #navalarchitecture #naval #maritime #offshoreenergy #oilandgas #offshorerenewables #offshorewind #offshoresolar

For those interested in 3D printing of metals, we have a nice paper out that deepens our understanding of how the printing strategy affects the microstructure and the resulting mechanical properties: https://lnkd.in/eNQkmbyK. This knowledge can be exploited to design metal parts with locally tailored microstructures and superior mechanical performance by, for example, combining different printing strategies and processing conditions.

Improving PCB fabrication is crucial as the demand for higher data and signal quality increases, driven by the advancements in 5G, 6G, and future wireless technologies. 5G technology, in particular, is poised to revolutionize the electronics industry by providing faster data speeds, reduced latency, and more reliable connections. These enhancements will support significant advancements in AI-driven electronics, IoT, and smart devices, boosting their performance and enabling new functionalities.

Two professors in mechanical engineering and Materials Science & Engineering, Texas A&M University recently joined forces as authors. Dr. Julie M. Schoenung, the Wofford Cain Chair III and Dr. Enrique J. Lavernia, the M. Katherine Banks Chair, have co-authored a reference guide, "Metallic Powders for Additive Manufacturing: Science and Applications." The recent explosive interest in 3D printing -- one of the most common example of additive manufacturing -- has fueled the need to understand and implement the atomization of metal powder. "Given our active involvement in the field, we saw the need for a book dedicated to the exploration of metal powders within the framework of additive manufacturing," Dr. Lavernia said.

Join James Rathburn Precision Circuit Technologies for a MEMBER ONLY Flexinar on July 31st! Flexible Hybrid Electronics and Additive Manufactured Electronics hold great promise and potential for leveraging the advantages of printed dielectrics and conductors. Several limitations in materials, deposition platforms, design and process methods have limited use to relatively simple demonstration vehicles and struggled to bridge the gap between the research lab science project and traditional printed circuit fabrication. Printed dielectrics have suffered from signal lossy materials that cannot withstand lead-free solder reflow, and particle-based inks remain poor conductors compared to bulk copper standards. Printing platforms are limited by the materials they can deposit, and most demonstrations are relatively low-layer count one-sided applications with fairly coarse geometries. Precision Circuit Technologies (PCT) will present an approach to additive manufacturing that leverages a Liquid Crystal Polymer AME-FHE base and the development of low-loss dielectric and particle fee metal inks along with printing platform refinements to achieve high layer count, double-sided circuit stacks that approach conventional laminated construction capabilities. Printing platform suppliers, ink formulators, and post-print processing equipment vendors have cooperated to further the goal of a "PCB Fab on a Desktop" to enable a user to print a complex, high-performance design quickly, test that design and refine performance to dramatically reduce the duration of iteration normally experienced with multiple design spins in a conventional PCB fabrication environment.
