IEEE NWF Section Meeting - 3-D Printing in Metal


Additive manufacturing (AM) is a growing technology that is looking to improve upon traditional machining capabilities.  Whereas traditional machining implements subtractive techniques to remove undesirable material, additive manufacturing is an iterative processes that builds geometry in a layer-by-layer style of production.  There are many styles of additive manufacturing of metals including, Laser Powder Bed Fusion (LPBF), Metal Binder Jetting, Direct Energy Deposition (DED), and hybrids of the above.  AM gives the opportunity to manipulate geometry and microstructure that is not available for traditional machining.  To take advantage of the increased ability to control geometry, topology optimization can be used to generate optimized geometry based on a set of constraints. In addition to macro-level manipulation, by adjusting laser power and speeds, microstructure can be controlled.

3-D Printing in Metal


Nicholas Hopkins is an Applied Research Engineer for Integrated Solutions for Systems (IS4S).  He graduated from Mississippi State Engineering in May 2019 with a B.S. in Mechanical Engineering.  He is a graduate student in a M.S. program for Mechanical Metallurgy with a concentration on additively manufactured materials, primarily high strength steels with intent to study for a PhD in Materials and Metallurgy at Alabama, Auburn or Texas A&M.

He has been working for IS4S (Integrated Solutions for Systems) for about a 3 years where he is currently an applied research engineer studying additively manufactured materials in quasi static and high strain rate applications.
