Solid Freeform Fabrication of Transparent Fused Quartz Using a Filament Fed Process

Luo, J.; Gilbert, L.J.; Qu, C.; Morrow, B.; Bristow, D.A.; Landers, R.G.; Goldstein, J.; Urbas, A.; Kinzel, E.C. (University of Texas at Austin, 2015)

Glass is a critical material for many scientific and engineering applications including optics, communications, electronics, and hermetic seals. Despite this technological relevance, there has been minimal research toward ...

Dynamic Resolution Control in a Laser Projection Based Stereolithography System

Pan, Yayue; Dagli, Chintan (University of Texas at Austin, 2015)

In a typical Additive Manufacturing system, it is critical to make a trade-off between the resolution and build area for applications in which varied dimensional sizes, feature sizes, and accuracies are desired. The lack ...

Toward Better Build Volume Packing in Additive Manufacturing: Classification of Existing Problems and Benchmarks

Araújo, L.J.P.; Özcan, E.; Atkin, J.A.D.; Baumers, M.; Tuck, C.; Hague, R. (University of Texas at Austin, 2015)

In many cases, the efficient operation of Additive Manufacturing (AM) technology relies on build volumes being packed effectively. Packing algorithms have been developed in response to this requirement. The configuration ...

Surface Roughness Optimized Alignment of Parts for Additive Manufacturing Processes

Delfs, P.; Töws, M.; Schmid, H.-J. (University of Texas at Austin, 2015)

The layered structure of Additive Manufacturing processes results in a stair-stepping effect of the surface topographies. In general the impact of this effect strongly depends on the build angle of a surface, whereas the ...

Improving Volumetric Accuracy of AM Part Using Adaptive Slicing of Octree Based Structure

Malyala, Santosh Kumar; Manmadhachary, A.; Kumar, Yennam Ravi (University of Texas at Austin, 2015)

In Additive Manufacturing (AM) processes, the layer-by-layer fabrication of complex geometries may lead to stair casing and thus error resulting in volumetric inaccuracies in the model. Using thinner slices reduces the ...

FE-Optimization and Data Handling for Additive Manufacturing of Structural Parts

Reiher, Thomas; Koch, Rainer (University of Texas at Austin, 2015)

Additive Manufacturing (AM) offers high potential due to its freedom of design for structural parts. Especially in combination with FE-based topology optimization an optimal use of material and thus significant weight ...
