As part of a research cooperation with TU Delft in the Netherlands, the engineering company knippershelbig GmbH in Stuttgart, Germany, and MG Metalltechnik GmbH in Matrei, Austria, Jansen has investigated the options for using 3D printing technologies to manufacture steel nodes. This new technology offers architects previously unimaginable design freedom for steel system facades: 3D printed steel nodes combined with VISS profiles form the foundation for constructing concave and convex shapes. The nodes can be formed on a bespoke basis with multiple arms and different angles, allowing both acute and obtuse angles to be created within a single node. The VISS³ facade is self-supporting; load is transferred directly via the profiles and connecting nodes without the need for a substructure. In this way, Jansen VISS³ enables the construction of complex free-form facades and roof lights of any shape.
