Abstract: In this talk, an introduction to the research activity in Dr. Yan’s group on 3D printing of the highly reflective materials (Cu and Cu alloys), hard­to­weld materials (7xxx Al alloys and IN738LC) and breathable mould steel will be firstly briefed. The focus is on developing cost­affordable, high­performance, 3D printed Ti and Ti alloys. Cost affordability is one of the most limiting factors to the scale­up of the 3D printing industry particularity regarding the very useful & valuable Ti materials. The approach developed by Dr Yan’s group is able to reduce the cost on feedstock powder from the normally ～US$300 per kg to ～US$30 per kg. Based on the low­cost Ti powder, typical Ti materials including CP­Ti, Ti­6Al­4V, Ti­10V­2Fe­3V and Ti­TiB2 composite have been developed by selective laser melting (SLM) in­situ alloying. A few issues in developing the cost­affordable Ti powders for 3D printing will be addressed.
