This model explores a double curvature perforated facade, using the ribs and paneling technique.
Size: 2000 x 1600 mm
Scale: 1 : 5
Materials: 1.5mm Grey cardboard for ribs
0.7mm White cardboard for perforated panels
Designed as a facade, the size of perforations reduces towards the top to control the amount and quality of light allowed to pass through.
In this final exercise, we use the knowledge of the rib structure, paneling tool and joints-and-sticks structure. We combined them together to achieve a roof structure and sunshading system. The overall form was derived from the previous 3d printing assignment. The joint was modified to accomodate the addition of a paneling system.

Images of previous assignments
3D printing prototype:
Form derivation: inner surface of revolved solid
Materials: basswood sheet 1.6mm, acrylic flat panels
Geometry is made to resemble a free form structure but panels can be mass fabricated.
Rib structure stiffened with acrylic ‘box’ panel formed from vacuum form process.
10X Scale up of original geometry. Further exploration needed to increase stiffness of joints without increasing depth of ribs. Bracing plate incorporated into rib structure and acts as a panel support simultaneously.
image for final project:
model is designed through a modular system. each slice is formed by 3 layer of playwoods to enhance the strenght of the model.
also, an extra node is also added in the model to reinforce the strenght of material. this is the scale up version of previous assignment in P2
p1: sectioning model
P3: 3D printing
designed a movable joint in the structure to achieve a twisting effect in the model
as some of you have encountered, using the new 3D printing machine (PA2200 sintering) requires you to be more involved. Such as checking for shells (that means your model is not water-tight) and holes, and manifold edges etc..
Here is a program that might be useful to you. Its called netfabb basic and its free. http://www.netfabb.com/basic.php
The process of checking and repairing your model usually takes less than a minute. Have a look at the simple tutorial here.
Cheers and good luck!
