| dc.description.abstract | Micro-scale selective laser sintering(μ-SLS) requires the use of nanoparticles(NPs) since the particle size needs to be an order of magnitude smaller than the melt pool in order to accurately sinter particles together to form a part. Most NPs properties are dependent upon size and thus, an exhaustive study of the physical and thermal properties of these NPs is required in order to successfully model and simulate the sintering process. In this paper we will present particle size characterization using Scanning electron microscopy (SEM), density measurements using He pycnometry, and X-ray Energy Dispersive Spectroscopy that were carried out to characterize the copper(Cu) nanopowder samples. Furthermore, the samples were sintered with different powers to estimate optimum power and exposure times and the results have been discussed along with further scope of work for fully characterizing the particles. | en_US |
