  报告题目:3D printing, and cost-affordable 3D printing of Ti and Ti alloys

  主讲嘉宾:严明 副教授(南方科技大学 材料科学与工程系)

  活动时间:9月26日(周四)10:00~11:20

  活动地点:李薰楼356会议室

  报告简介:

  3D Printing & Additive Manufacturing can find its root in the concept of ‘Industry 4.0’ that was initially proposed by Germany. It is booming in both R&D sector and a few industrial sectors including education, mould making, biomedical and aerospace engineering. 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), hard-to-weld materials (7xxx Al alloys and IN738LC) and breathable mould steel will be firstly briefed.

  But of course the focus is on developing cost-affordable, high-performance, 3D printed Ti and Ti alloys. Cost affordability is one of the most limiting factors to the scale-up 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 low-cost Ti powder, typical Ti materials including CP-Ti, Ti-6Al-4V, Ti-10V-2Fe-3V and Ti-TiB2 composite have been developed by selective laser melting (SLM) in-situ alloying. A few issues in developing the cost-affordable Ti powders for 3D printing will be addressed.
