This book was released on 1990 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many variables are involved in the process of fabricating a dense dental casting which accurately duplicates the wax pattern. The type of sprue design that is utilized has been shown to play a important role in the casing process. The literature is filed with conflicting results and conclusions regarding proper sprue attachment design. The objective of this investigation was to evaluate the effects of four different sprue attachment designs (Gradual Constriction, Abrupt Constriction, Flared, and Straight) on the porosity and castability of three different dental casting alloys: Firmailay, a Type II gold alloy; Jel-5, a palladium-silver alloy; and Rexillium III, a base-metal alloy.

Available in PDF, EPUB and Kindle. Book excerpt: The aim of the present paper is to make a review of the properties of dental alloys, fabricated using Additive Technologies (AT). The microstructure and mechanical properties of Co-Cr alloys as well as the accuracy and surface roughness of dental constructions are discussed. In dentistry two different approaches can be applied for production of metal frameworks using AT. According to the first one the wax/polymeric cast patterns are fabricated by 3D printing, than the constructions are cast from dental alloy with as-printed patterns. Through the second one the metal framework is manufactured form powder alloy directly from 3D virtual model by Selective Electron Beam Melting (SEBM) or Selective Laser Melting (SLM). The microstructure and mechanical properties of Co-Cr dental alloys, cast using 3D printed patterns, are typical for cast alloys. Their dimensional and adjustment accuracy is higher comparing to constructions, produced by traditional lost-wax casting or by SLM. The surface roughness is higher than that of the samples, cast by conventional technology, but lower comparing to the SLM objects. The microstructure of SLM Co-Cr dental alloys is fine grained and more homogeneous comparing that of the cast alloys, which defines higher hardness and mechanical properties, higher wear and corrosion resistance.

Available in PDF, EPUB and Kindle. Book excerpt: Metal casting is an old but important manufacturing technology, with an estimated 90% of durable manufactured products containing a casting. While traditional metal casting has existed for thousands of years, it remains a complex process under controlled conditions that suffers from variable casting outcomes, where the same casting design can have on casting run be defect free, and another casting run that must be scrapped. This variability has long been considered unavoidable, and even acceptable by the metal casting community. However, this outlook is no longer feasible, as nations across the world try to improve sustainability and reduce energy consumption. This dissertation presents original research to improve the performance of sand casting, the most widely used metal casting process, so that the industry can improve its sustainability. Leveraging additive manufacturing (AM) via 3D sand-printing enables us to reimagine the design principles of 3D mold geometry to improve casting quality and reduce casting variation. In this research, 3D sprue geometries were systematically studied for the naval alloy nickel aluminum bronze (NAB). When compared to the straight sprue geometry traditionally used in industry, the optimized 3D sprue geometries increased the ultimate flexural strength by 28% with while also reducing the variation with statistical significance. In addition to 3D sprue geometries, this dissertation studied 3D runner geometries for both AM and traditional molds. The optimized 3D runner geometries improved casting consistency by reducing the variance of the ultimate flexural strength by a statistically significant 74%. To accelerate our understanding of melt filling in sand molds, this dissertation also investigated new process monitoring techniques that can be integrated with IoT sensors (internet-of-things) with the potential to rapidly identify defective castings. Computer vision tracked the melt head in the runner system of open molds to extract its velocity, while ultrasonic sensors provided a means to measure in-gate velocity that previously could not be measured. This novel process measured the liquid metal surface height as the mold filled and then calculated the in-gate velocity using the surface height data. Overall, the innovations presented in the dissertation have made original contributions to the science of 3D mold design via 3D sand-printing to improve casting performance and in-process monitoring capabilities.
