3D Printed Fastener-Free Connections for Non-Structural and Structural Applications – An Exploratory Investigation
(University of Texas at Austin, 2018)
The construction industry has shown increasing interest in AM technologies and has
successfully implemented various proof of concept projects using different AM processes. Much
of the research on AM in the construction ...
The Recycling of E-Waste ABS Plastics by Melt Extrusion and 3D Printing Using Solar Powered Devices as a Transformative Tool for Humanitarian Aid
(University of Texas at Austin, 2018)
This study demonstrates the EcoPrinting principal, which makes use of renewable energy to
realise a low carbon footprint means of recycling waste plastics into feedstock for Fused Filament
Fabrication (FFF) 3D printing. ...
Economies of Complexity of 3D Printed Sand Molds for Casting
(University of Texas at Austin, 2018)
Additive Manufacturing (more commonly referred to as 3D printing) is resulting in a
metamorphosis of the sand casting industry as 3D printed sand molds enable castings of
unmatched geometric complexity. The manifold ...
Additive Manufacturing of Energetic Materials
(University of Texas at Austin, 2018)
Over the last decade, additive manufacturing gained a lot of interest within the defense
industry. However, printing energetic materials such as explosives or solid propellants remains
a challenge. A research work with ...
The Effect of Shear-Induced Fiber Alignment on Viscosity for 3D Printing of Reinforced Polymers
(University of Texas at Austin, 2018)
Material printed with large scale additive manufacturing systems such as the Big Area
Additive Manufacturing (BAAM) system experience a wide range of shear rates during the
extrusion process. The shear rate can vary over ...
Mechanical Challenges of 3D Printing Ceramics Using Digital Light Processing
(University of Texas at Austin, 2018)
Digital light processing (DLP) 3D printing can be used for manufacturing complex
structures using a variety of materials, which would be nearly impossible using traditional
manufacturing methods. Recent work at Sandia ...
Design and Robotic Fabrication of 3D Printed Moulds for Composites
(University of Texas at Austin, 2018)
3D printing technologies have a direct impact on manufacturing the composite structures and in
particularly fabrication of molds. Molds produced through additive manufacturing methods would
greatly improve product features. ...
A Post-Processing Procedure for Level Set Based Topology Optimization
(University of Texas at Austin, 2017)
This paper addresses two issues: 1. Topology optimization yields designs that may require
support structures if additively manufactured, which increase material and clean-up costs. 2.
Topologically optimized designs ...
Additive Manufacturing Utilizing Stock Ultraviolet Curable Silicone
(University of Texas at Austin, 2017)
Extrude and Cure Additive Manufacturing (ECAM) is a method that enables 3D printing
(3DP) of common thermoset materials. Ultraviolet (UV)-curable silicone is an example of a
thermoset material with a large number of ...
Continuous Property Gradation for Multi-Material 3D-Printed Objects
(University of Texas at Austin, 2018)
Modern AM processes allow for printing multiple materials. The resulting objects can be
stiff/dense in some areas and soft/porous in others, resulting in distinct physical properties. However, modeling material gradients ...
