Staircase G. is the first project to be realised using the Selective Paste Intrusion (SPI) method. As the central architectural element of a private house on Lake Garda, the staircase extends over two storeys and a total height of ten metres. The 3D-printed core of lost formworks allows the steps to cantilever from it, thus separating them from the surrounding interior walls and enabling a crucial separation for sound insulation.
The load-bearing element of the staircase consists of 18 SPI-printed boxes that act as lost formwork. Weight optimisation to reduce the material used and assembly aids in the form of recesses for inserting the steel steps were already included during the planning stage. On the construction site, the steps were simply placed in the inserts provided in the respective formwork element. The individual elements together with the steps were then placed on top of each other, reinforced and cast at the same time.
This modular construction method allows for staircases to be installed in a short amount of time and offers many aesthetic and technical options for the design of the staircase and its separation from the surrounding building for enhanced sound insulation.

"Bridge the Gap" is a research project of the AMC TRR 277 – a Collaborative Research Centre for Additive Manufacturing in Construction that is funded by the German Research Foundation – and demonstrates the applicability of the SPI process for load-bearing components. The 5.0 x 2.5 metre spanning prototype of a pedestrian bridge was designed, modelled and then structurally optimised using computational methods. The large printing space of our SPI printer of 4 x 2.5 x 1.6 metres allowed for all parts to be printed in a single print, within only six hours. The 21 load-bearing SPI-printed segments are designed to match the material properties of the SPI concrete and are connected to each other via optimised joint interfaces. An internal post-tensioning system, the channels of which were also printed, reinforces the bridge against asymmetrical loads.
