DESCRIPTION:Dr. Christian Leinenbach\, Empa Dübendorf\nIn the last couple
  of years\, metal additive manufacturing (AM) has emerged from a mere prot
 otyping technology to a real manufacturing technology with applications in
  many industry sectors (e.g. aerospace\, biomedical engineering\, power ge
 neration). The layer-by-layer consolidation during laser powder bed fusion
  or laser direct metal deposition results in unique time-temperature profi
 les in the materials\, which can lead to out-of-equilibrium microstructure
 s\, meta-stable phases\, micro-segregation and cracking. Up until now\, on
 ly a small number of conventional alloys is currently used for AM. Many tr
 aditional wrought and cast alloys were not optimized for processing via AM
  and they might have to be optimized to make them printable. On the other 
 hand\, the special processing conditions during AM with the very rapid hea
 ting and cooling cycles and the short consolidation times can allow for th
 e fabrication of alloys and composites that are otherwise difficult or imp
 ossible to fabricate.\nIn this presentation\, I will talk about the materi
 al challenges in metal AM and our activities with regard to the design and
  optimization of structural alloys for laser-based AM technologies. In add
 ition\, I will talk about our approaches to use AM for fabricating parts w
 ith locally tailored microstructures and novel functionalities.
