Abstract
Large scale binder-jetting additive manufacturing has been available since almost a decade. While it offers great opportunities for the fabrication of complex ornate forms, so far, the potential of this printing method is not fully explored. Moreover, binder-jetted objects have never been tested for outdoor use and performance, because of the weak bond of the printed parts. This paper presents a design strategy that makes possible the fabrication of large, outdoor installations, with such a fragile material as printed sandstone. The presented process was developed for a full-scale installation of acoustic mirrors that was designed, manufactured and post processed in only a few steps. In the larger picture, this paper discusses how 3D printing can allow for design optimisation and reduction of material, while it proposes post-processing methods that strengthen and seal the printed objects for exterior use.
