Modeling Thermal Expansion of a Large Area Extrusion Deposition Additively Manufactured Parts Using a Non-Homogenized Approach
(University of Texas at Austin, 2019)
Interest in the use of large area extrusion deposition additive manufacturing (LAEDAM) to
create tools for creation of composites is on the rise, due to its ability to create complex shapes
rapidly. To ensure the parts ...
Measurement and Analysis of Pressure Profile Within Big Area Additive Manufacturing Single Screw Extruder
(University of Texas at Austin, 2019)
Pressure distributions within a single screw extruder are dependent on several factors,
namely, processing parameters and flow geometry. The Big Area Additive Manufacturing
(BAAM) system involves a complex flow geometry ...
Increasing the Interlayer Bond of Fused Filament Fabrication Samples with Solid Cross-Sections using Z-Pinning
(University of Texas at Austin, 2019)
The mechanical properties of parts made by fused filament fabrication is highly anisotropic,
with the strength across layers (z-axis) typically measuring ~50% lower than the strength along
the direction of the extruded ...
Creating Toolpaths Without Starts and Stops for Extrusion-Based Systems
(University of Texas at Austin, 2019)
Toolpath generation for extrusion-based additive manufacturing systems, called slicing,
involves operations on polygonal contours that are derived from an STL file. Slicing generates
multiple paths per layer (both ...
