Researchers develop novel topology optimization technology for large-scale 3D printing
A team of researchers from the University of Liege and the Delft University of Technology have developed two new methods of topology optimization designed specifically for large-scale 3D printed parts. Due to the wide nozzle diameters required to 3D print large structures, there are limitations in how parts can be […]
Rethinking Thermal Design: Utilizing Your Thermal Budget to Your Best Advantage
Temperature is a major design constraint for any system that generates heat, including automotive, aerospace, telecom, industrial, and lighting applications. Even a system that is 90% efficient still has to dissipate 10% of its power as heat. Excessive heat can substantially reduce the operating life of lithium batteries and LEDs, […]
Optimizing a wind turbine nacelle cover to meet LCOE demand
Glass fiber-infused nacelle cover drawing. Illustrated by Susan Kraus. Optimized three-part design reduces foam core usage with strategically placed foam core stiffeners. Four-millimeter-thick outer skin manufactured from glass fiber and custom epoxy/polyester resin. In-situ molded stiffeners decrease overall cycle times. Global wind energy installations surged in 2020, with 93 gigawatts […]
Using 3D Optical Profiling for Full-Field Hotspot Detection
Chemical mechanical polishing (CMP) – also known as planarization – has long been the most commonly employed technique for smoothing and flattening wafer surfaces during the fabrication of semiconductor integrated chips (IC). This approach has been common practice for decades. During this time, post-CMP evaluation has become the standard means […]
Material-structure-performance integrated laser-metal additive manufacturing
Cross-scale coordination Laser-based additive manufacturing has the potential to revolutionize how components are designed. Gu et al. suggest moving away from a strategy that designs and builds components in a serial manner for a more wholistic method of optimization for metal parts. The authors summarize several key developments in laser […]
