Week Three

Reading: Kolerevic B. 2003. Architecture in the Digital Age

Kolerevic described three fundamental type of fabrication techniques in the reading. Outline the three techniques and discuss the potential of Computer Numeric Controlled fabrication with parametric modelling. (150 words max)

The three fundamental types of fabrication techniques described by Kolerevic are CNC cutting (i.e. two dimensional fabrication), the CNC multi-axis milling and contour crafting. The first advantage of CNC fabrication with parametric modelling is that architects are more involed in the fabrication process because they with konwing the production capability and availability of digital driven fabrication equipment are able to design specifically for the capaility of the machine. Secondly, CNC fabrication with parametric modeling allow s architects to control over the budget by precisely controlling the designed geometry and building materials, and also rethink the structural design, for example, structure and building skin in monocoque. Finally, since buildings are mostly one-off, highly customized products, CNC fabrication with parametric modelling can introduce a different logic of seriality in architecture and produce relatively cheap and one-off mass-customized products.


Week Three

Surface Creation

When thinking about making the surfaces, the first thing I considered was the curve surfaces which is how curve could they be. Then, i combined surfaces with the waffle and dound out it would be easy to have the upper curves which are used to loft the surfaces horizontal, but surfaces seem a little boring, so i didn’t keep my final decision lofted ftom two horizontal lines, and this brought me some problem when making the waffle.


Week Four Panels & Waffle

My 3D paneling is basicly formed by two pyramids and there are holes

My waffle structure compared to the one taught in the Workshop section is that my waffle is twisted too much which caused problem with my 2D panels, because the waffle is twisted too much which makes my 2D panel became mostly like a double- curved surface and undevelopable.

created on the surfaces of the pyramids by using Weaverbird on Grasshopper. And my idea of 2D paneling is originated from the pattern of the tradinitional Chinese symbols on the bronze container.


Week Four

Laser Cutting

In the lasercutting process, the highlight i have learnt is to remember to mirror the elements in order to aviold the elemets being burnt. However, i also found if i put dash lines as the edges of the panels on the cut layer in the laser cut template, i can save my time from scoring the edges again for folding easily.


Week Five





- The design 3D boolean pattern

The four images on the sides is my process of building up my design. Firstly i waned to create some fllower like object, for example the dandelion, so i tried to use morph 3D in Grasshopper, but i failed because i cannot create a solid or closed polysurfaces in this method. So i Got my second way, which is to break the sphere surface into pieces and then extrude the surfaces to a point outside the surfaces . However, i gave up my second idea because the geometry is too complecated which will probably cause failures when 3D print. So, i finally worked out my third idea, and made its angles less shape to succeed in 3D print.


Week Five


The third iteration that i mention in the previous page is used as my final idea. The reason i used this iteration is the size of the part projecting outward of pattern is able to be altered. By controlling the projection i can increase the successful rate of 3D print which is decreasing the shape angles. In addition, I create the porosity by intesecting the 3D geometric patterns, then boolean union them toghther to to create larger cutting objects for trimming the cube with ‘boolean difference’ command on Rhino. Moreover, by moving the smaller or individual 3D pattern, intersecting them with the cube to show special or interesting carves from the cube.

Task 01 Matrix The first pair of surfaces in the first row of the matrix is used to be the basic surfaces. Because i am interested in the way they are curved and i want to create a spiral structure with two surfaces so these two surfaces are quite suitable.

Task 02 Matrix By trying the point attarction and curve attraction, these attractors will only change the grids of each cell in order to change the position of the inserted 3D pattern. So only can use the point attarctor which controls the scale of the patterns according to distance from the grids points. So after by manipulating the points attractors, i used four points to controls the scale and also play with the magnitude of the extent of the change.


Week Six

Final Isometric Views




The failure of the 2D paneling Because the basic surfaces were over- twisted, the surfaces mostly beame doubled curved surfaces which are not developable and also the surface domain number i used to panel the 2D custom panel were 5 by 5 which are too less. Or another way to solve this problem is to morph or panel 3D paneling onto the surface.


Appendix Process

The 3D pattern design

The process of designing this pattern is quite difficult. Firstly, i tried to use a sphere as a basic surface to create this pattern by adding surface domain numbers and paneling pyramids onto the sphere along the grids. However, it didn’t work, because the edges of the pyramids didn’t connect so that a solid pattern cannot be obtained. First 3D pattern

So, the second method came out, which is spliting the sphere into small surfaces, and then extrude the surface to point to gain pyramids.
