DESCRIPTION:Dr. Wei Li\, Assistant Professor from Department of Mechanical 
 Engineering\, University of Texas at Dallas will give a seminar titled "St
 udying Additive Manufacturing with Multi-physics\, Multi-scales\, and Mult
 i-materials Modeling Framework & Low-temperature Metal AM" to the interest
 ed faculty and students at Discovery Park.\n\n \n\nAbstract\n\nAdditive Ma
 nufacturing (AM)\, also called 3D printing\, is being widely accepted in v
 arious applications\, such as aerospace\, automotive\, biomedical\, and de
 fense industries. Due to the complicated manufacturing characteristics\, o
 nly experimental approach is not sufficient to investigate all the key det
 ails in AM process and product. This seminar will showcase several additiv
 e manufacturing topics in Dr. Wei Li’s research lab which are emphasized
  on modeling approaches. In addition\, an unexplored metal AM process\, lo
 w-temperature directed energy deposition (low-temp DED)\, will be introduc
 ed in the seminar. The main topics include: (1) Multi-physics modeling stu
 dy of AM processes including powder bed fusion\, directed energy depositio
 n\, wire arc additive manufacturing\, bio 3D printing\, binder jetting. Th
 e multiple physics involve particle movement\, heat & mass transfer\, phas
 e change\, printed geometry\, and microgravity conditions in the internati
 onal space station\, Moon\, or Mars. (2) Multi-scale modeling study of res
 idual stress\, porosity\, and microstructure in metal AM process. This res
 earch area is focused on the grain evolution and porosity’s influence in
  local regions surrounding the pores. (3). Multi-material modeling study o
 f the printing of functionally gradient materials with directed energy dep
 osition process. A study case of Stainless Steel 316L/Inconel 718 function
 al gradient material is introduced in this topic. (4). Low-temperature DED
 . The presenter will introduce some unique benefits of the DED process con
 ducted in low temperature conditions (-20 °C for example)\, such as powde
 r saving\, high cooling rate\, and better mechanical strength.\n\n \n\nBio
 graphy\n\nDr. Wei Li specializes in the research of additive manufacturing
  and 3D printing. He is Assistant Professor in Mechanical Engineering Depa
 rtment in the University of Texas at Dallas. His research interests includ
 e metallic AM with multiple materials\, pore defect and influence\, wire a
 rc additive manufacturing\, fine machining of AM part\, repair with AM pro
 cess\, bio-3D printing\, in-space additive manufacturing\, low-temperature
  AM\, and modeling of AM process. Before joining UT Dallas\, Dr. Li was th
 e post-doctoral researcher in the Department of Mechanical and Aerospace E
 ngineering at University of California\, Davis. Dr. Li earned his Ph.D. de
 gree in Mechanical Engineering from Missouri University of Science and Tec
 hnology (former Missouri University-Rolla) in 2018. He has two M.S. degree
 s: one in Manufacturing Engineering from Missouri University of Science an
 d Technology in 2017\, the other in Aerospace Engineering from Tongji Univ
 ersity in 2012.
