μ-SLS of Metals: Design of the Powder Spreader, Powder Bed Actuators and Optics for the System
(University of Texas at Austin, 2015)
Nanopowders have a tendency to form agglomerates due to high surface energy and the
presence of attractive van der Waals forces. To overcome this problem, we present a powder
spreading mechanism design that can alleviate ...
An Experimental-Numerical Investigation of Heat Transfer During Selective Laser Melting
(University of Texas at Austin, 2015)
The heat transfer in and around a part being fabricated via Selective Laser Melting (SLM) is
numerically simulated while considering the surrounding powder bed modeled to have an
effective thermal conductivity. By ...
Investigation of the Scan Strategy and Property of 316L Stainless Steel-Inconel 718 Functionally Graded Materials Fabricated by Selective Laser Sintering
(University of Texas at Austin, 2015)
316L stainless steel and Inconel 718 alloy functionally graded materials were
fabricated by selective laser melting with a novel approach which combined powder-bed with powder-feed pattern. Two different scanning strategies ...
Low Temperature Selective Laser Melting of High Temperature Plastic Powder
(University of Texas at Austin, 2015)
In a typical plastic laser sintering or melting system, powder bed temperature is
maintained above the recrystallization temperature of the powder material to prevent
the parts under process from warping until the whole ...
Modeling of Powder Bed Processing – A Review
(University of Texas at Austin, 2015)
Many models have been developed to model powder beds and these methods can be
implemented to model a powder bed for Selective Laser Sintering, Selective Laser Melting and
any other technique of additive manufacturing ...
The Heterogeneous Compensation for the Infiltrative Error of the Binder Jetting Additive Manufacturing Processes
(University of Texas at Austin, 2015)
In binder jetting additive manufacturing, such as Three Dimensional Printing (3DP) and Patternless
Casting Manufacturing (PCM, a process similar as ExOne and VoxelJet), the building error is mainly
caused by the infiltration ...
