Inspired by the Bean in Chicago, We intended to replicate it with a simple construction manner. Compare with the perfect curvature of the Bean with extremely high technology of CNC milling and sanding down , we tried to use 3D print nodes which allow us to have only the nodes that are the high technology part of the design while the rest of the parts can be easily fabricate with hand tools .
Step 1: Define Geometry in Rhino and Grasshopper
So the initial geometry is done in rhino and panelized in grasshopper. With the help of millipede that is a grasshopper plugin, the nodes are then topologically optimized to be as effective as possible , while the other fabrication details are extracted from the model .
Step 2: Topologically Optimized Joints
Here shows how the structure layerings are done and also how the joints are connected . With ABS 3D Print nodes , the rods are wooden rods that are cut at the front for the connection with 3D print node and pins are then used to lock them into place .
While the whole structure is then added a layer of acrylic with dichroic film to give it an elegant color ,then which is hold on the the wooden structure with the pins again.
Step 3: ABS 3D Print Nodes
Every nodes have their own number which will be corresponds to the rods and the panels. This information is printed on the the node with 3D printer too .
Step 4: Cutting the Rods
To simplify the work , paper strips are lasercut and scored with the numbers that they are further processed to cut the wood pieces and drill the holes for the pins.
Step 5: Dichroic Films
Dichroic Films are cutted in the form of the panels and carefully stick onto the surface
Step 6: Final Product
With the informations embedded onto the nodes, rods and panels, the structure is established on a lasercut landscape.
