Simulating 20 Layers of Maraging Steel with LPBF Using AM PravaH In this video, we explore a detailed simulation of 20 layers in the Laser Powder Bed Fusion (LPBF) process for Maraging steel alloy, using AM PravaH software. Watch as we delve into the intricate layer-by-layer manufacturing of a thin metal wall, capturing every phase of the process. We also showcase how phase changes are tracked, Gaussian laser distribution with Fresnel reflections is calculated, and Marangoni convection and Discrete Element Method (DEM) are applied for precise powder bed preparation (with particles sized between 18-36 microns). This sophisticated simulation was executed on a powerful 20-core processor and completed in under a day, thanks to advanced preventive time step controls. #additivemanufacturing #3dprinting #3dmodeling #engineering #innovation

Precision in Motion Equals Throughput in Production Innovative technologies from artificial intelligence to low Earth orbit are pushing the boundaries of HDI and advanced substrate design. These new markets present new material challenges and demand greater precision, density and yield. To meet these demands, PCB manufacturers need a laser via drilling system that is in constant motion for maximum accuracy and throughput. The Geode™ PCB laser drilling platform delivers better, faster and more consistent vias by harnessing the power of light and sound with the coordinated motion of lasers, galvos and stages. For the ultimate victory, you must go beyond the traditional.

The coating materials employed in PVD applications are commonly referred to as "target materials." This designation accurately captures their function in the deposition process, where they undergo bombardment by electron beams or ions, resembling a target being hit by projectiles. A sputtering target represents a specific type of target material utilized for coating within the vacuum sputtering technique. While sputtering targets have a more limited scope, in real-world applications, the term "target material" generally encompasses sputtering targets. #PVD #CoatingMaterials #TargetMaterials

📢 #Nanomaterials Volume 14, Issue 5 is out! Cover Story: Two Structural Designs of #Broadband, Low-Loss, and Compact TM Magneto-Optical #Isolator Based on GaAs-on-#Insulator The team from Shandong University proposed two optical isolator designs on the GaAs-on-insulator platform, a less explored area compared to silicon-on-insulator (#SOI) platforms. These isolators, utilizing the TM basic mode, are assessed for non-reciprocal phase shift (#NRPS) via numerical simulation. They achieve 35 dB isolation bandwidths exceeding 53.5 nm and 70 nm at 1550 nm, with insertion losses of 2.59 dB and 2.25 dB respectively. The authors also introduced a multi-mode interferometric (#MMI) coupler tailored for these designs and discussed manufacturing processes considering simulated tolerances. 🔗 Check out all published papers here: https://lnkd.in/eggdgBes 📨 Sign up for our newsletter to get notified of a new issue release at: https://lnkd.in/eCtVPMmA #openaccess
