In our most recent roundup of 3D printing webinars and events, we told you about the free “Let’s Talk Concrete 3D Printing: A Multidisciplinary Approach” webinar by Spanish company ACCIONA.

The webinar, held the morning of June 30, lasted about 100 minutes and focused on the use of 3D concrete printing (3DCP) technology in the value chain.
