Saptarshee Mitra has recently published a doctoral thesis, ‘ Experimental and numerical characterization of functional properties of sand molds produced by additive manufacturing (3D printing by jet binding) in a fast foundry .’
.
Delving into hybrid casting and improved methods for creating metal molds, Mitra analyzes varied printing parameters and their effects on mechanical properties. Centered around improving production in foundries, the author investigates ways to create molds in a completely automated manner, taking advantage of some of the most classic benefits in 3D printing—from greater affordability and faster production time, to better quality in prototypes and parts.
.
“Besides, the absence of tooling costs makes this process particularly economical, and much complex geometry that cannot be manufactured using traditional sand casting can be reconsidered,” states Mitra. 3D printers are generally faster, easier to use and cheaper than other add-on technologies. It is also possible to make foundry sand molds […]
