Chemistry from 3D-printed objects

April 26, 2019
Author(s)
Matthew R. Hartings, Zeeshan Ahmed
3D printing technology has started to take hold as an enabling tool for scientific advancement. Born from the marriage of computer-aided design and additive manufacturing, 3D printing was originally intended to generate prototypes for inspection before

Evaluation of a thermo-mechanical model for prediction of residual stress during laser powder bed fusion of Ti-6Al-4V

April 2, 2019
Author(s)
Rishi Ganeriwala, Maria Strantza, Wayne King, Bjorn Clausen, Thien Q. Phan, Lyle E. Levine, Donald W. Brown, Niel Hodge
The build-up of residual stress in a part during laser powder bed fusion provides a significant limitation to the adoption of this process. These residuals stresses may cause a part to fail during a build or fall outside the specified tolerances after

Simulation of TTT curves for additively manufactured Inconel 625

January 1, 2019
Author(s)
Carelyn E. Campbell, Greta Lindwall, Eric Lass, Fan Zhang, Mark R. Stoudt, Andrew J. Allen, Lyle E. Levine
The ability to use common computational thermodynamic and kinetic tools to study the microstructure evolution in Inconel 625 (IN625) manufactured using the additive manufacturing (AM) technique of laser powder-bed fusion is evaluated. Solidification

3D Printing in Cell Culture Systems and Medical Applications

December 18, 2018
Author(s)
Max J. Lerman, Josephine Lembong, John G. Gillen, John P. Fisher
3D printing serves an important role in various biomedical research applications, including but not limited to culture systems and implantable devices. In this review, we discuss recent development in the applications of 3D printing technologies for

A DESIGN FOR ADDITIVE MANUFACTURING ONTOLOGY TO SUPPORT MANUFACTURABILITY ANALYSIS

October 1, 2018
Author(s)
Samyeon Kim, David W. Rosen, Paul Witherell, Hyunwoong Ko
Design for additive manufacturing (DFAM) provides design freedom for creating complex geometries and guides designers to ensure manufacturability of parts fabricated using additive manufacturing (AM) processes. However, there is a lack of formalized DFAM

Flow-induced crystallization during materials extrusion additive manufacturing

September 10, 2018
Author(s)
Lily Northcutt, Sara Orski, Kalman D. Migler, Anthony Kotula
Material extrusion additive manufacturing processes force molten polymer through a printer nozzle at high (> 100 s-1) wall shear rates prior to cooling and crystallization. These high shear rates can lead to flow-induced crystallization in common polymer
