LPW Technology Ltd, which makes metal powders for the additive manufacturing (AM) industry, has published a case study which examines the sources and impact of porosity in metal AM entitled: ‘Porosity – Powder or process derived?’.
‘When porosity causes issues in a built part, it’s important to understand the root cause,’ said Dr Rob Deffley, LPW’s research & development manager. ‘Porosity might originate from the metal powder or the AM process. This case study explores the different types of porosity, how they are identified, and follows LPW’s experienced applications engineers as they analyse an Inconel 718 AM component failure. ‘Porosity – Powder or process derived?’ can be found here.
