The study used the rePowder ultrasonic atomiser from AMAZEMET to produce spherical and flowable powders with a crystalline microstructure, suitable for Laser Beam Powder Bed Fusion (PBF-LB) Additive Manufacturing. #additivemanufacturing #3dprinting #research #medical

Sharing some of the group's recent publications: ⚡ Experimental and computational studies on hot cracking in single laser tracks of aluminium alloy AA2024 and related implications for laser powder bed fusion, Nov 2024 In this paper, we investigate whether insights into crack susceptibility at the single-track level can provide guidance for manufacturing crack-free parts using Laser Powder Bed Fusion (L-PBF). ⚡ Additive manufacturing of functionalised atomic vapour cells for next-generation quantum technologies, Oct 2024 Using an additive manufacturing (AM) technique—vat polymerisation by digital light processing—we demonstrate, for the first time, a 3D-printed glass vapour cell. #additivemanufacturing #latestresearch #cfam #laserpowderbedfusion #quantumtechnologies #research

Check out our recent publication: "In Situ Analysis of the Effect of Ultrasonic Cavitation on Electrochemical Polishing of Additively Manufactured Metal Surfaces." This study explores the effects of combining ultrasonic cavitation and electrochemical polishing on additively manufactured 316L stainless steel. The research examines how ultrasonic amplitude and electrolyte temperature influence electrochemical behavior and polishing characteristics through in-situ potentiodynamic scans and electrochemical impedance spectroscopy (EIS). This work will be presented at the Manufacturing Science and Engineering Conference (MSEC) 2024 next week. https://lnkd.in/gRFTYQ64

Additive manufacturing (AM) using powder bed fusion (PBF) techniques, such as selective laser sintering (SLS) and multi-jet fusion (MJF) can be used to build complex geometries that are difficult or impossible to produce using traditional manufacturing methods. Although their mechanical properties have been extensively characterised, very few works have addressed their fracture behaviour, especially in relation to the anisotropy due to the build orientation. Research work at Bristol Composites Institute with my colleague Jagan Selvaraj investigated this anisotropy in the fracture behaviour of polyamide 12 polymer manufactured by SLS and MJF using a combination of experiments and numerical modelling of Mode I compact tension (CT) specimens. Experiments were monitored by digital image correlation (DIC) and infra-red thermography (IRT). https://lnkd.in/ecyTm9Zp

New publication in JMMP MDPI! 🌟 📜 Synchronized Multi-Laser Powder Bed Fusion (M-LPBF) Additive Manufacturing: A Technique for Controlling the Microstructure of Ti–6Al–4V This paper explores the use of a hexagonal array of synchronized lasers in additive manufacturing to modify the microstructure of Ti-6Al-4V and promote equiaxed grain formation, revealing that laser power, scanning speed, and laser spacing significantly affect grain structure, with optimal conditions yielding up to 55% equiaxed grains and reduced results at higher scanning speeds due to lower absorbed heat and thermal crosstalk. 🎓 Hamed Attariani, Shayna Petitjean, and Aaron Michael Niekamp 🏫 Wright State University Read the full article here: 🔗 https://lnkd.in/enA4frbq #technology #laser #powerbed #fusion #additivemanufacturing #microstructures

Congratulations to Adianne Alamban and Muneeza Ahmad for their publication in "Nanomaterials" entitled "2D Ruddlesden–Popper Perovskites with Polymer Additive as Stable and Transparent Optoelectronic Materials for Building-Integrated Applications"! This work benefitted from funding by the National Science Foundation (NSF) and shared facilities at ASU, specifically the Eyring Materials Center and the Advanced Electronics and Photonics Core Facility. In this article, they demonstrate how to design solution-processed light absorbers with semitransparency for integration into the built environment. The use of 2-dimensional (2D) perovskite materials combined with a polymeric additive enabled an improved combination of transparency, optoelectronic performance, and operational stability under accelerated stress testing!
