Laser Additive Manufacturing of Water Atomized Pure Iron
Alan Rogalsky, together with the academics from the University of Waterloo, conducted research into the processing of water atomised pure iron powders via two Additive Manufacturing (AM) methods. These include Laser Powder-Fed (LPF) AM and Laser Powder Bed (LPB) AM. Due to the lack of studies on pure iron powder, that is LPF- and LPB-AM processed, the academics decided to examine powder feedstock surface morphology, particle size distribution, flow properties, density and thermal behaviour, by applying Scanning Electron Microscopy, Camsizer XT, FT4-Powder Rheometer, Ultrapyc Pycnometer, and Simultaneous Thermal Analysis. Mechanical properties and microstructure of fabricated parts were also investigated, using an Instron universal material testing machine, a Nano-CT scanner, and Laser Scanning Confocal Microscopy. This presentation discusses the findings, their potential application, and outlines the future research work.
University of Waterloo, Post-Doctoral Fellow, Waterloo, Kanada
Allan Rogalsky, together in collaboration with RioTinto, is currently studying low cost iron and steel powders for additive manufacturing. Prior to this, Allan focused on researching the stiffness and processability of hybrid hydrogels for biomedical applications. He believes that his work, in this multidisciplinary area, gives him a unique skill set to address the varied challenges associated with metal powder printing in the world of additive manufacturing.
