Presented by Jan Olek, Purdue University; Reza Moini, Purdue University; Pablo Zavattieri, Purdue University; and Jeffrey Youngblood, Purdue University The presentation will examine both, the challenges but also innovation opportunities, offered by the 3D printing technology in the field of structural concrete. The opportunities range from the ability to create complex and architecturally unique structures without the need for intricate formwork to the ability of creating an “internal architecture” of the elements that can results in novel mechanical responses. The challenges involve compliance with the existing building codes, integration of reinforcement, and durability. The current focus areas of the industry and the research communities will be critically examined and illustrated by examining the relationships between processing parameters, structure and performance characteristic of the 3D printed as a way to customize the response of the printed elements.
