Abstract Scope |
Titanium alloys are widely used in aerospace and medical industries for their high strength-to-weight ratios and good corrosion resistance. However, the high affinity for oxidation often leads to costly processing environments to maintain the purity of the finished product. The lifetime of a Ti-6Al-4V powder batch in an electron beam powder bed fusion (EB-PBF) additive manufacturing (AM) production environment is determined by an individual manufacturer’s process optimization. In practice, Ti-6Al-4V powder is recycled across many builds until oxygen pickup increases to a level that is no longer acceptable. Findings and observations from the literature with respect to Ti-6Al-4V powder recycling and subsequent effects on part performance will be discussed in this review presentation. Potential knowledge gaps and opportunities to optimize this process will be highlighted in this talk to increase powder batch lifetime and potentially reduce overall process cost. |
