To stimulate the discussion about large-scale 3D printing, I started 3dprintingarchitecture.net, which is a combination of a blog, Linkedin-discussion group, and a Facebook page:

3d printing architecture is an independent knowledge and inspiration platform for architects, designers, researchers, engineers, and fabricators with an interest in additive manufacturing for the building industry. The goal is to stimulate innovation by sharing knowledge and connecting people. The group focuses on big-scale 3D printing such as 1:1 prototypes, building elements, and complete buildings.

Join the discussion at Linkedin

In this group, the discussions will focus on both the technical aspects of large-scale 3d printing and the different goals to be achieved.
