New Developments in Processing and Control of Selected Area Laser Deposition of Carbon
(1994)
Selected area laser deposition (SALD) has been used to deposit carbon from methane, hydrogen,
oxygen, and argon mixtures using a third generation deposition system. The effect of two laser
scanning hardware/software ...
Microstructures and Strengths of Metals and Ceramics made by Photopolymerbased Rapid Prototyping
(1996)
Metal and ceramic flexure specimens were fabricated using a photopolymer-based rapid
prototyping technique. Photosensitive resins (inks) were produced by dispersing 50 - 55 vol%
metal or ceramic powders in a photopolymer ...
Active - Z Printing: A New Approach to Increasing 3D Printed Part Strength
(University of Texas at Austin, 2017)
Research suggests that topology and build parameters in Fused Filament Fabrication (FFF)
play a vital role in determining mechanical properties of parts produced by this technique. In
particular, the use of 2D layers ...
Reducing Mechanical Anisotropy in Extrusion-Based Printed Parts
(University of Texas at Austin, 2017)
The mechanical performance of 3D printed components is highly dependent upon the
orientation of the part relative to the build plane. Specifically for extrusion-based printing systems,
the bond between successive layers ...
Magnetohydrodynamic Drop-on-Demand Liquid Metal 3D Printing
(University of Texas at Austin, 2017)
We present a novel method for liquid metal drop-on-demand (DOD) additive manufacturing
of three-dimensional (3D) solid metal structures. This method relies on magnetohydrodynamic
(MHD)-based droplet generation. Specifically, ...
Selective Separation Shaping of Polymeric Parts
(University of Texas at Austin, 2017)
Additive manufacturing (AM), or 3D printing has enjoyed a recent surge of attention over the past decade.
AM is a process in which digital 3D design data is used as input to build physical objects by combining
sequence ...
Fiber-Fed Laser-Heated Process for Printing Transparent Glass
(University of Texas at Austin, 2017)
This paper presents the Additive Manufacturing (AM) of glass using a fiber-fed process.
Glass fiber with a diameter of 100 μm is fed into a laser generated melt pool. A CO2 laser beam
is focused on the intersection between ...
Stereolithography-Based Manufacturing of Molds for Directionally Solidified Castings
(University of Texas at Austin, 2018)
Directionally solidified components, such as single crystal turbine blades, are
typically grown using shell molds prepared using a lost wax process that begins with injection-molded wax positives. These positives have ...
A Sustainable Additive Approach for the Achievement of Tunable Porosity
(University of Texas at Austin, 2018)
This study aims to design a green additive approach for the fabrication of controlled porosity on
hydrogels. Although hydrogels have been of common use in tissue engineering, the generation of
controllable porosity remains ...
Development of a Thermoplastic Biocomposite for 3D Printing
(University of Texas at Austin, 2018)
Organosolv lignin, a natural cross-linked phenolic wood polymer is a by-product of the
pulping process in the paper industry. It is a renewable organic natural product with potential
application in many areas. It has ...
