Digital production of bionic structural parts

With his »Natural Column Project«, Daniel Büning has created the world's first architectural part with a complex internal microstructure, which was generated with a digital simulation process and turned into reality using an additive manufacturing process. This project would not have been possible without a layer-by-layer digital production process, since these complex structures, which are inspired by nature, cannot be produced using "traditional" CNC-based production methods. These types of parts can only be created with large-format 3D printing systems.

The Natural Column Project came together at voxeljet's service center on the VX4000 large-format printer, which can print sand molds with a volume of up to eight cubic meters. The structure was printed in four individual parts to facilitate the handling of the structural element with dimensions of 1720 x 921 x 1761 mm. The exhibit impresses with its outstanding richness of detail and high strength. It is another example of how 3D printing has become the enabler of trend-setting production Technologies.
