Abstract Scope |
Through advancements in technology over the last several years, additive manufacturing has become increasingly mainstream in the manufacturing industry. A method that was observed in this study for improving additive manufacturing processes is the incorporation of magnets into the manufacturing process. Laser powder bed fusion experiments were conducted in order to evaluate the effects of the introduction of magnets on parts printed. Stainless steel 316L was printed onto Ti64 substrates using both spot welding and line scanning techniques. It was observed that magnets had a varying effect on the melt pool and the keyhole depth through x-ray image analysis. Additionally, the various magnets altered the melt-flow dynamics of tungsten particles in the melt pools generated through line scanning. There is strong evidence that magnetic fields could be a viable solution to increasing additive manufacturing’s precision, though future research is needed to visualize and quantify this effect on printed parts. |
