Speeding up Additive Manufacturing by Means of Forming for Sheet Components with Core Structures
Stephan Rosenthal,Marlon Hahn,A. Erman Tekkaya,Sebastian Platt,Stefan Kleszczynski,Gerd Witt 한국정밀공학회 2022 International Journal of Precision Engineering and Vol.9 No.4
A new process combination route consisting of additive manufacturing (AM) with a subsequent forming operation is proposed. The process route has the opportunity to increase the efficiency of the AM process route up to 360%. Stainless steel 316L sheets with different core structures (similar to sandwich sheets) are produced by AM, characterized, and formed in a die bending operation. The bending characteristics of this novel semi-finished product can be accurately predicted in a numerical simulation. The new process route is discussed in detail and compared to conventional AM parts in terms of the production efficiency.
