Abstract:

It has been more than two decades since stereolithography began to emerge in various forms of additive manufacturing and 3D printing. Today these technologies are proliferating world wide in various forms of advanced manufacturing. The largest segment of the 3D printing market today involves various forms of polymer component fabrication, particularly complex structures not attainable by other manufacturing methods. Conventional printer head systems have also been adapted to selectively print various speciated human cells in attempts to construct human organs, beginning with skin and various tissue patches. These efforts will be discussed along with metal and alloy fabrication of a variety of implant and bone replacement components by creating powder layers which are selectively melted into complex forms (such as foams and other open-cellular structures) using laser and electron beams directed by CAD software. Efforts to create a “living implant” by bone ingrowth and vascularization within these implants will be discussed briefly. Efforts to develop printer heads for direct metal droplet deposition as in other 3D printing systems will be briefly described since these concepts will allow for the eventual fabrication of very large and complex products, including automotive and aerospace structures and components.
Lawrence E. Murr is Emeritus Professor, Department of Metallurgical, Materials and Biomedical Engineering, at the University of Texas at El Paso. He holds a B.Sc. degree from Albright College, and B.S., M.S., and Ph.D. degrees from Penn State. Over a 50-plus year career, Professor Murr has published over 800 papers and 21 books (the latest: “Handbook of Materials Structures, Properties, Processing and Performance” (2 vols.), Springer, 2015). Recent honors include the TMS 2007 Educator Award, the 2007 John S. Rinehart Award (a TMS Symposium Award for global leadership in shock and high-strain-rate phenomena), and the 2008 Henry Clifton Sorby Award presented by the International Metallographic Society (IMS) for recognition of lifetime achievement in the field of metallography. In 2009, Professor Murr received the Albert Easton White Distinguished Teacher Award from ASM International. Professor Murr was chosen for a Piper Professor of 2010 Award for “Outstanding scholarly achievements and superior teaching at the college level”, a Texas higher education program of the Minnie Stevens Piper Foundation. In 2014, Professor Murr was named a Distinguished Life Member, of Alph Sigma Mu (Metallurgical & Materials Science and Engineering) Honor Society “for a long history of outstanding career accomplishments.”
