The article reports on the research about the significance of fiber lasers for rapid prototyping conducted by SPI Lasers, a Southampton, England-based firm which specializes in power fiber lasers used in the industrial market. The researchers try to show that rapid prototyping can be further improved through better surface finish and increased fill density made possible by fiber lasers. Moreover, it was emphasized that the temporal and spatial stability of fiber lasers help in the improvement in layer uniformity.
Provides information on the application of laser-based prototyping techniques which transform a conceptual design into a solid prototype. Description of the stereolithography which was pioneered by 3D Systems; How the selective laser sintering from DTM Corp. works; Main applications for rapid-prototyping equipment.
