Improved Microstructure and Increased Mechanical Properties of Additive Manufacture Produced Ti-6Al-4V By Interpass Cold Rolling
(University of Texas at Austin, 2013)
Distortion, residual stress and mechanical property anisotropy are current challenges in additive manufacturing (AM) of Ti–6Al–4V. High-pressure, interpass rolling was applied to linear
AM parts and resulted in a change ...
Design and Assessment of an AM Vending Machine for Student Use
(University of Texas at Austin, 2013)
Due to prohibitive costs, access to Additive Manufacturing (AM) technologies at academic
institutions tends to be limited to upper-level courses that feature significant project-based
coursework, such as capstone design. ...
Utilizing Additive Manufacturing Techniques to Fabricate Weight Optimized Components Designed using Structural Optimization Methods
(University of Texas at Austin, 2013)
This paper describes a preliminary study of the application of structural optimization
techniques to the design of additively manufactured components, using load testing to failure
to establish true load carrying capacity. ...
Selective Laser Sintering of Negative Stiffness Mesostructures for Recoverable, Nearly-Ideal Shock Isolation
(University of Texas at Austin, 2013)
Honeycomb materials are well known for providing lightweight stiffness, strength, and
energy absorption capabilities. For most honeycomb materials, energy absorption occurs when
individual cells collapse progressively. ...
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 ...
Design of Auxetic Sandwich Panels for Structural Applications
(University of Texas at Austin, 2013)
Based on an analytical modeling analysis, a sandwich structure with a 3D re-entrant
auxetic core was designed. Auxetic samples were produced by electron beam melting (EBM) and
selective laser sintering (SLS), and compared ...
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 ...
Additive Manufacturing Laser Deposition of Ti-6Al-4V for Aerospace Repair Applications
(University of Texas at Austin, 2013-08-16)
Parts or products from high performance metal are very
expensive, partly due to the processing complexities during
manufacturing. The purpose of this project is to use additive
laser deposition and machining processes ...
Experimental Investigation of Different Cellular Lattice Structures Manufactured by Fused Deposition Modeling
(University of Texas at Austin, 2013)
Experimental tests were conducted to evaluate the compressive properties (yield strength and
compressive modulus) and build time for five different cellular lattice structures fabricated by the
Fused Deposition Modeling ...
Analysis of Ferroelectric Ceramic Fabricated by Binder Jetting Technology
(University of Texas at Austin, 2013-08-16)
The M-Lab system from ExOne was used to fabricate 3D structures of BaTiO3 ceramic
with applications that include dielectric capacitors, sensors, and integrated circuits. For this
project, layer thicknesses of 15 and 30 ...
