New Publication Highlight: Laser Enhanced Direct-Print Additive Manufacturing (LE-DPAM) of mm-Wave Antenna using LTCC Dielectric Paste for High Temperature Applications By: Seng Loong Yu , Christopher Curran, Anton Polotai, Eduardo Antonio Rojas-Nastrucci This paper, presented at IEEE's Wireless and Microwave Technology Conference (WAMICON), focuses on a new additive manufacturing approach for antennas. The laser-enhanced direct print additive manufacturing (LE-DPAM) process is used to fabricate and characterize low temperature co-fired ceramic (LTCC) paste for high temperature applications. Coplanar waveguides (CPW) were used to characterize the performance of the additive manufactured LTCC substrate and the permittivity is extracted using direct S-parameters measurements up to 40 GHz. The extracted permittivity is calculated to be an average of 21.3 over 1–40 GHz. A 4 dBi mm-wave antenna is designed and fabricated to demonstrate the capability to additive manufacture LTCC materials, with resonances in the 32–34 GHz range which endured at temperatures up to 980 °C. To the authors’ best knowledge, this is the first fully additive manufactured solution for LTCC technology, where both LTCC and conductive traces were printed using a microdispensing AM process. #GoERAU #ERAU_EECS_EXCELLENCE #AddativeManufacturing #Antenna #Laser https://lnkd.in/geVbrXv5

Few words about additive - EBM (Electron Beam Melting)

Electron Beam Melting (EBM) enables you to better print metal alloy parts that are suitable for high-temperature applications. EBM is also the only additive technology that allows you to avoid cracking of difficult-to-manufacture alloys during manufacturing. In this article we catch up with Markus Ramsperger, staff engineer at GE Additive, to discuss how EBM is being used to create components for high-temperature applications that can’t be produced using other additive methods.

Combining accuracy with productivity 📈 Fiber laser marking with indexing, where every detail finds its perfect place. Index marking, also known as indexing, is a technique used in laser marking systems to precisely position the laser beam in relation to the workpiece. This method involves moving the workpiece or the laser beam in a controlled manner to ensure accurate marking on specific areas of the material. Index marking allows for consistent and repeatable results, making it ideal for applications where precise alignment and placement of marks or patterns are crucial. By synchronizing the movement of the laser with the indexing mechanism, manufacturers can achieve high-speed, high-precision marking on various materials, including metals, plastics, and ceramics. This process is commonly utilized in industries such as automotive, aerospace, electronics, and medical devices, where quality and traceability are paramount. #lasermarking #indexmarking #fiberlaser

🚀 New Feature in THERCAST® NxT 3.0: Physical Model of Surface Tension! 🚀   We're excited to announce a major enhancement in THERCAST® NxT 3.0: the introduction of a physical model for surface tension. Surface tension significantly influences the flow of liquid metal, particularly in continuous casting and the filling phases of foundry processes. This is crucial for ensuring the surface quality of cast products and managing the behavior of the meniscus and liquid slag interaction.   Key Highlights: 🌟 Surface Tension Force (STF): Now incorporated into the Navier-Stokes equation for incompressible fluids using a semi-implicit formulation. 🌟 Wettability Effect: Implemented based on the wetting angle description from Bellet's work. 🌟 Marangoni Effects: The Marangoni force, related to surface tension gradients and temperature variability, can now be activated via the interface.   These advancements are particularly beneficial for sensitive alloys like aluminum, where oxidation can create an alumina layer that impacts flow. The ability to simulate these forces directly enhances the precision and quality of our modeling capabilities.   Join us in leveraging these new features to push the boundaries of simulation technology!   Arianna Gotti François FRASCATI #THERCAST #Simulation #SurfaceTension #ContinuousCasting #FoundryProcesses #MarangoniEffect #Innovation #Engineering #Manufacturing #transvalor   [3-6] Explore the details and benefits of these new capabilities!

In previous publications by the LLNL team, tailoring laser energy input spatially and temporally has been shown to control microstructure and residual stress in laser powder bed fusion (L-PBF) additive manufactured parts. In this latest work, led by Kaila Bertsch and first-authored by Connor Rietema, the use of large area surface annealing with a secondary diode laser is investigated as a method to control the microstructure of Ti6Al4V during L-PBF. To determine the effect of layer annealing on the microstructural development through the height of AM Ti6Al4V components, all cylinders were built with the same initial parameters but different in-situ diode annealing schedules. Temperature gradients that developed in the parts during annealing were determined by measuring the surface temperature with an infrared camera and the base plate temperature with a thermocouple, then applying a simple, conduction-only thermal simulation to model the temperature throughout the height of the build. With this framework, the microstructural evolution could then be tied to the temperature history. This information is critical to developing annealing strategies that localize heat treatments for complete 3D spatial control of the microstructure. The work was co-authored by John Roehling and William L. Smith. https://lnkd.in/d8e9h8wk
