Data-driven characterization of computational models for powder-bed-fusion additive manufacturing

July 31, 2020
Author(s)
Yan Lu, Zhuo Yang, Paul W. Witherell, Wentao Yan, Kevontrez Jones, Gregory Wagner, Wing-Kam Liu, Jason C. Fox
Computational modeling for additive manufacturing has proven to be a powerful tool to understand the physical mechanisms, predict fabrication quality, and guide design and optimization. Varieties of models have been developed with different assumptions and

3D printed optical concentrators for LED arrays

July 19, 2020
Author(s)
Behrang H. Hamadani, Jonathan E. Seppala, Clarence J. Zarobila
Additive manufacturing methods based on photopolymerization offer a great potential for fabrication of high quality, highly transparent optical components. One appropriate use of these technologies is related to fabrication of parts that can be used in

Effects of laser-energy density and build orientation on the defect structure, microstructure and tensile properties of Inconel 718 parts manufactured with laser powder bed fusion

June 30, 2020
Author(s)
Dillon Watring, Jake Benzing, Nik Hrabe, Ashley Spear
This study investigates the processing-structure-property relationships of Inconel 718 manufactured by laser powder bed fusion. Three di erent build conditions were selected for the Inconel 718 specimens: 0 build orientation and 38 J/mm3, 0 build

Improving patient outcomes with regenerative medicine: How to move the needle forward in cell manufacturing, standards, 3D bioprinting, AI enabled automation, education and training

Carl Simon Jr., Josh Hunsberger, Claudia Zylberberg, Preveen Ramamoorthy, Thomas Tubon, Crystal Ruff, Ram Bedi, Kurt Gielen, Lynn Fisher, Jed Johnson, Priya Barankiak, Behzad Mahdavi, Michael Hadjisavas, Shannon Eaker, Cameron Miller
Regenerative Medicine Manufacturing Society (RMMS), is the first and only professional society dedicated specifically towards advancing manufacturing solutions for the field of regenerative medicine. RMMS' vision is to provide greater patient access to

Evaluation of Nondestructive Volumetric Testing Methods for Additively Manufactured Parts

June 4, 2020
Author(s)
Anne Francoise H. Obaton, Bryan Butsch, Stephen McDonough, Nans Laroche, Yves Gaillard, Jared B. Tarr, Patrick Bouvet, Rodolfo Cruz, Alkan Donmez
Additive manufacturing enables the production of customized and complex parts. These two aspects are very attractive for aerospace and medical sectors. However, in these critical sectors, governed by strict safety requirements, the quality of the parts is
