This week’s selection is Lamp Nr. 1 by studiooberhauser.
This item is a decorative sculpture for outdoor use. It is 3D printed in concrete and is designed to accommodate a light source inside. The exterior holes allow the light to escape and generate some interesting shadow effects.
The object was 3D printed using the Selective Cement Activation process (SCA), which seems to be developed by Germany-based Additive Tectonics. This process is quite different from typical 3DCP concrete extrusion methods and is more like binder jetting.
In SCA, a flat layer of cement powder and fine aggregate is laid down. Then a toolhead selectively deposits water where solid portions are to exist. Another dry layer is added, and the process repeats. At the end of the job, the object is buried in a dry mix, much like you’d see in an SLS or LPBF job.
The process does produce a rather coarse texture, which you can see in the images. While some applications might require a smooth surface, here the roughness adds to the character of the object. We’re looking for aesthetic value over geometric perfection in this application.
