Innovative Education in Additive Manufacturing in China
(University of Texas at Austin, 2012)
Beginning in 1992, China began to conduct research on additive manufacturing (AM) (i.e.,
rapid prototyping manufacturing or solid freeform fabrication). These studies included three main
areas: processes, equipment, and ...
Conformal Lattice Structure Design and Fabrication
(University of Texas at Austin, 2012)
One application of additive manufacturing is for fabrication of customized, light-weight material
called Conformal Lattice Structures (CLS), a type of cellular structure with dimensions of 0.1 to 10
mm. In this paper, ...
GT ME TOR: A High School Education Program in Systems Engineering and Additive Manufacturing
(University of Texas at Austin, 2012)
The Defense Advanced Research Projects Agency (DARPA) is sponsoring the MENTOR
program as the outreach part of its Adaptive Vehicle Make suite of programs. Georgia Tech has
been awarded a contract to involve up to 1000 ...
Creating Complex Hollow Metal Geometries using Additive Manufacturing and Electroforming
(University of Texas at Austin, 2012-08-22)
Additive manufacturing introduces a new design paradigm that allows the fabrication of
geometrically complex parts that cannot be produced by traditional manufacturing and assembly
methods. In this paper, the authors ...
Analyzing Product Lifecycle Costs for a Better Understanding of Cost Drivers in Additive Manufacturing
(University of Texas at Austin, 2012-08-20)
The costs of additive manufactured parts often seem too high in comparison to those of
traditionally manufactured parts, as the information about major cost drivers, especially for
additive manufactured metal parts, is ...
Unit-Cell-Based Custom Thermal Management through Additive Manufacturing
(University of Texas at Austin, 2012)
Using previously-defined effective thermal conductivities for structural unit cells, a
custom thermal-management structure has been developed for a powered ankle-foot orthosis.
The structure provides the requisite personal ...
An Investigation of the Effects of Quantum Dot Nanoparticles on Photopolymer Resin for Use in PolyJet Direct 3D Printing
(University of Texas at Austin, 2012-08-15)
The addition of quantum dot (QD) nanoparticles to additive manufacturing (AM) media
provides the opportunity to create artifacts with complex geometry that also have unique optical
characteristics. However, the addition ...
Fast Recoating Methods for the Projection-based Stereolithography Process in Micro- and Macro-Scales
(University of Texas at Austin, 2012)
The purpose of this paper is to present a recoating method for the development of a direct digital
manufacturing (DDM) process that can be an order of magnitude faster than other currently available
DDM processes. In the ...
Proposal for a Standardized Test Artifact for Additive Manufacturing Machines and Processes
(University of Texas at Austin, 2012-08-15)
Historically, standardized test parts are used to quantitatively evaluate the performance of a
machine or process. While several different additive manufacturing (AM) test parts have been
developed in the past, there are ...
Ceramic-Polymer Additive Manufacturing System for Ultrasound Transducers
(University of Texas at Austin, 2012)
A modified multi-layer lithography process is used to additively manufacture highresolution netshape ceramic structures by photopolymerizing a ceramic-polymer slurry using
structured light patterns. This paper will discuss ...
