This workshop is the occasion to tackle one of the most challenging and constraining feature in 3d
printing: gravity . The contradiction here is that we, architects, need overhang or cantilever features
in order to create space, while contour crafting demands the overlapping of layers of material to be
in equilibrium.
The overhang depends on material characteristics, which will not examine during this workshop, but
also on the geometry of the print, and the structural implications that it might have.
This workshop will be again the occasion to address the relationship between form and structure.
We will both print and simulate modelled geometries in order to understand their behaviour and
eventually derive conclusions as a tool kit, as in the first workshop.
Workshop objectives
1. to model simple lofted geometries. In Rhino and Grasshopper.
2. to simulate the structural performance of a structure.
3. to feed the result of this analysis into the design of a new surface.
4. to produce bottom-up design evolutive catalogues.
5. to 3d print cantilever structures with the extruder mounted on the large robotic arm.
6.In groups of 3/4, design and model catalogues of 12 geometries. Digitally test a chosen geometry,
and use the results of the test to reinforce the geometry. And repeat the process.
