Lighter weights, lower costs in additive manufacturing

“Critical instant analysis, a new process for improved structural optimization in additive manufacturing, unveils the possibility of designing products that are lighter in weight and cheaper to produce.”

“In their paper “Lightweight Structure Design Under Force Location Uncertainty,” presented at SIGGRAPH 2017 in Los Angeles, Mechanical Engineering professor Levent Burak Kara and his colleagues detail their research on improved structural optimization in additive manufacturing, research that unveils the possibility of designing products that are lighter in weight and cheaper to produce.”

“Structural optimization refers to a product being as strong as possible while remaining as light as possible. Traditionally, structural optimization is achieved by analyzing external forces however, because additive manufacturing creates products that can be stressed by a nearly infinite number of forces that are neither known nor fixed, a new way of integrity analysis is needed.”

 

“To address this, Kara and his team developed a process called critical instant analysis. Through digital mapping and simulation, they are able to determine the points on a design that are most vulnerable to critical force contact.”
