Defect Morphology in Ti-6Al-4V Parts Fabricated by Selective Laser Melting and Electron Beam Melting
(University of Texas at Austin, 2013-08-16)
In order to investigate the morphology of defects present in Selective Laser Melting (SLM)
and Electron Beam Melting (EBM) processes, Ti-6Al-4V specimens were fabricated with varying
porosity using non-optimum processing ...
Melt Pool Geometry Simulations for Powder-Based Electron Beam Additive Manufacturing
(University of Texas at Austin, 2013-08-16)
It is known that the melt pool geometry and dynamics strongly affect the build
part properties in metal-based additive manufacturing (AM) processes. Thus, process
temperature predictions may offer useful information of ...
Surface Morphology of Selective Laser-Melted Titanium
(University of Texas at Austin, 2013)
The surface morphology of biomaterials is one of the most important biocompatibility
factors. In this paper, the change in surface morphology of selective laser-melted titanium with
process parameters was investigated ...
Manufacture of Functionally Gradient Materials using Weld-Deposition
(University of Texas at Austin, 2013)
When the inherent inhomogeneity of Additive Manufacturing techniques is carefully
exploited, the anisotropy transforms into the desired distribution of the properties paving the way
for manufacture of Functionally Gradient ...
Modeling and Experimental Validation of Nickel-based Super Alloy (Inconel 625) Made Using Selective Laser Melting
(University of Texas at Austin, 2013)
The formation of constituent phases in Selective Laser Melting of Inconel 625 is a function of
local temperatures, hold times at those temperatures, local cooling rates and local compositions
in the melt pool. These ...
High Viscosity Jetting System for 3D Reactive Inkjet Printing
(University of Texas at Austin, 2013)
High viscosity ink is a potential solution for the improvement of current 3D ink jetting
technology. In this study, experiments are carried out to study a series of inks with differing
viscosities jetted with PicoDot™ ...
Design of an Empirical Process Model and Algorithm for the Tungsten Inert Gas Wire+Arc Additive Manufacture of Ti-6Al-4V Components
(University of Texas at Austin, 2013)
In the wire+arc additive manufacture process parameters can be varied to achieve a wide range
of deposit widths, as well as layer heights. Pulsed Tungsten Inert Gas was chosen as the deposition
process. A working envelope ...
