Abstract
This research analyzes the technical feasibility of manufacturing jewelry castings using the lost wax technique, substituting wax by the use of resins within the framework of 3D stereolithography printers. To achieve this goal, a pair of distinct 3D ring designs have been crafted: a robust signet ring and an intricate filigree ring. The purpose behind this decision is to determine whether the unique features of these two different designs have any noticeable effect on the result. Five different commercial resins have been utilized, with one of them explicitly formulated for casting purposes. Non-castable resins generate a unique, weathered appearance, due to the variability in ash residue within the mold after resin combustion, yielding unpredictable outcomes and diverse sample characteristics such as grainy texture, cracks, and a corroded effect. Examining the castable resin reveals its optimal performance for smaller elements like the filigree ring, showcasing remnants of supports or layers originating from the resin's printer curing process. On the contrary, larger resin-abundant objects like the signet ring result in notable flaws, attributed to gas accumulation within the mold, exerting internal pressure and causing mold rupture, leading to metal leakage.
期刊介绍:
The International Journal of Metalcasting is dedicated to leading the transfer of research and technology for the global metalcasting industry. The quarterly publication keeps the latest developments in metalcasting research and technology in front of the scientific leaders in our global industry throughout the year. All papers published in the the journal are approved after a rigorous peer review process. The editorial peer review board represents three international metalcasting groups: academia (metalcasting professors), science and research (personnel from national labs, research and scientific institutions), and industry (leading technical personnel from metalcasting facilities).
