Increasing Process Speed in the Laser Melting Process of Ti6Al4V and the Reduction of Pores During Hot Isostatic Pressing
(University of Texas at Austin, 2017)
Additive manufacturing of titanium alloys has gained intensive attraction from industry and
academia. Moreover, for additively fabricated parts consisting of Ti6Al4V, hot isostatic pressing
(HIP), is widely used as a ...
Fracture Mechanism Analysis of Schoen Gyroid Cellular Structures Manufactured by Selective Laser Melting
(University of Texas at Austin, 2017)
Ti-6Al-4V triply periodic minimal surface (TPMS) structures with biomorphics
scaffold designs are expected to be the most promising candidates for many biological
applications such as bone implants. Fracture is the main ...
Development of an Experimental Test Setup for In Situ Strain Evaluation During Selective Laser Melting
(University of Texas at Austin, 2017)
Selective Laser Melting (SLM) is an Additive Manufacturing (AM) process which still
underlies a lack of profound process understanding. This becomes obvious when deformation and
crack formation can be observed in SLM ...
Additive Manufacturing of Metal Bandpass Filters for Future Radar Receivers
(University of Texas at Austin, 2018)
Selective laser melting (SLM) is a powder-bed fusion (PBF) process that bonds successive layers
of powder with a laser to create components directly from computer-aided design (CAD) files. The
additive nature of the SLM ...
Topology Optimized Heat Transfer Using the Example of an Electronic Housing
(University of Texas at Austin, 2018)
Function integration is a key issue for an efficient and economic usage of Additive
Manufacturing. An efficient heat transfer by topology optimized structures is a rarely considered
approach which will be outlined with ...
Model Development for Residual Stress Consideration in Design for Laser Metal 3D Printing of Maraging Steel 300
(University of Texas at Austin, 2018)
Design optimization of laser metal 3D printed structural components requires prediction of
build-process induced residual stresses that vary with part geometry and affect distortion and support requirements during the ...
Effects of Thermal Camera Resolution on Feature Extraction in Selective Laser Melting
(University of Texas at Austin, 2018)
Selective Laser Melting (SLM) is a common additive manufacturing process which uses a
laser energy source to fuse metal powder layer by layer. Engineering properties and
microstructure are related to the part’s thermal ...
Effect of Wall Thickness and Build Quality on the Compressive Properties of 304L Thin-Walled Structures Fabricated by SLM
(University of Texas at Austin, 2018)
The specific strength of lightweight lattice structures built with SLM is of interest to the
aerospace industry. Honeycombs were manufactured with increasing wall thicknesses (which
increases density) and tested under ...
Additive Manufacturing of Liners for Shaped Charges
(University of Texas at Austin, 2018)
A Shaped Charge (SC) is an explosive device used to focus a detonation in a desired
direction, and has applications in demolition and oil extraction. The focusing relies on a void in
the explosive mass, shaped by a metal ...
Examination of the Connection Between Selective Laser-Melted Components of 316L Steel Powder on Conventionally Fabricated Base Bodies
(University of Texas at Austin, 2018)
The advantages of selective laser melting lie in the production of complex, small
components in small batches. For large-volume components, the use of additive manufacturing
(AM) processes is limited by the available ...
