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)

In the reading Kolerevice desrcibed subtractive fabrication, formative frabraction and additive frabraction. Subractive frabcation involves cutting materials out from a solider materials by using machinery tools such as the CNC Milling, which the computer have a series of coding that control the machine to cut the specific part of the required material. This have been a contrast to additive frabcation, which involves incremental forming adding materials in layer by layer such as 3D printing that is also control by computer codings but instead 3D printing build up models by layers. Formative fabrication refer to reforming and reshaping the materials into the shape that have designed, for example heating up materials like glass, mental turn them into a soften stage and deforming its orgin shape turn to the the shape required.


Week Three

Surface Creation

Surface 1

Surface 2

Surface 3

Surface 4

The first surface is developed with larger curvey shape, the base edge of both surface is aline on the ground and one of the point was starting at 0,0,0 in the rhino interface, as well as the rest of the surfaces to make sure they are able to stand alone. However, for the first surface the curvatura was big that seems to be quite floating and the base is small, which it cannot made into physical models. The second explore the idea of high and low, which one surface is much higer compare to the other surface. For the third surfae it have a large curvatura at the base and the base of the left surface is reallity small contrast with the opposite surface that have a quite square look. For the forth surface, that is wider at the base bottoom and become smaller and smllaer each layer, which formed a trapezoid shape.


Week Four Panels & Waffle

2 paneled surface is created, one of the back is a 2D panel surface that is created by using grasshopper and lunchbox tool, while the 3D panel is first created by using rhino and set up a brep conponnent that refer into the grasshopper. Also for the 3D panel it have set an offset point which point attraction in the middle of the panel surface, to created a curved inward effect alone with larger panels are around the outsider and the middle panel models is much smaller. For the 2D to have more variations opening is created and arrange from intense to loose start from the left conern.

This is my second waffle structure that I made into a phycial model. The first surface I have selected is surface 3, however, surface 3 have little support from the ground and the surface is very extrude the waffle strcuture is very cravey and cannot stand alone. For solve that I adjusted the surface and formed surface 4 and created a much straight edge waffle structure, that can standalone nicely and being self supported. Particularly, because this structure is much straighter that in the physical model it is much easier to build out.


Week Four

Laser Cutting

For this project the laster cutting for the waffle structure is created using grasshopper and then baked the flatten structure into rhino, while the panel is refer to the grasshopper and baked into the rhino interface as meshes and use the rhino command mesh to Nurbs to create surface to unroll, and also use panelling tool ptTriangulateFaces to create triangle surface that is able to build, the also using panelling tools to unroll 2D surfaces and use unroll surface to unroll 3D panels. Lastly, using pttags to create 5mm tabs and label each panels. Then arragne them in the Fablab lastering tample and seperate lines into hatch layer in red line that laster cut will half cut through such as the labels and foldded panels. The put the cut object into the cut layer, such as the waffle strcuture in black colour. The Panels used 290gsm ivory card and the waffle strcuture used 1mm mountboard.


Week Five

Boolean 1

Boolean 2 Boolean 3

Boolean 4

Boolean 1 used point attraction and have a geometric shape of a sphere that have arrange from large to samller sphere shapes and have been cut in a 1/8, that is learn from the workshop. Developed on boolean 1, Boolean 2 used a more straight edege shape squares and octahedron shape that is provided in lunchbox. And for this structure I used random attraction to would create a disorder arragnement. For booldean 3, it is in much an order and for this I used platonic dodecahedron, also reference in lunchbox, but the overhand for this model is very large, which it maynot be able to 3d print. Boolean 4, I used a 3 series of data which different sized platonic icosahedron and set with random attraction to create this forms, on the edge of the thickness analysis, it was quite thin, when 3d printing will be a bit risky.


Week Five


From all the forms I have build this forms will be the most interesting to look at, so instead of the cutting it in 1/8, because the whole structure is quite thin espeically along the edge. I have cut diagonly and from the boolean, for the surface it creates a sharp top from by the edge of the icosahedron shapes, especially different icosahedron in different size range makeing the surface looks different for each section. To build up this strcuture I have used a mix of point attraction and random attraction to create a disorder arragne in grasshopper and then bake the cube along with the shape use boolean difference comand to cut the model. The overall shape of the structure would look a bit like a rocky mountains having high point, lower plane area and cave like hiddren spaces represented with dotted lines. By rotating the structure, when it is upside down, it can been seen as an overhang a part of the strcuture, especailly on the side of the structure it was flat. From that view shows the idea of porosity and permeability, from a top view there are two parts of the strcture have holes and openings allowing subject, such as air, sunlight, water, people go into the space, which having movement and interaction between people and the strcuture alone with other elements from the environment inside the strcutre, having circulation in the space.


Week Six Task 01

Task 01 Matrix I first start to explore the with the curve surface which have been as as 1.1 and 1.2, to see how the curve may change the panels both in 2D and 3D, which with this two sit of surface the panels have been created quite simple and used random attraction and curved attraction to explore on the attractions and offset. Developping from 1.1 and 1.2 I have further explore the idea of high and low surfaces shown in 1.3, which still maintain the idea of curvatura surface alone play with height of the surface, alone with a bit complex 2D panels that have opennings and used point attraction to create the inwards surface. Unforunally, when I tried to build this surface, it have been extuded too far, which the structure cannot support it self. This where the 1.4 comes from, which I adjust the curve to make more stable by pull one side of the surface inwards a bit. Then, build up the model by using surface 1.4 with complex panels. Also having the idea of flow of the dropping rainwater, I created a 3d panels that is curved inwards shown in 1.4, which collect the water and they would run off from the straight edges.


Week Six Task 02

Task 02 Matrix To start explore the 3D boolden, I first start to be have quite regular and ordered shapes like 1.1 and 1.2, which I used curved attraction and point attractions, which explore the difference between the different attraction method. This 2 methods create quite reular and order patterns. Compare these two, I have changing the size of my shape to tried how this may make them different when they boolden difference. In 1.3, I went a bit over and further used 3 random attraction tried to create a disordered effect that shapes are lines ups and have different sizes. However, for this one the shpes I create is a bit too small, which they cannot be boolden each other. From that I have an idea that combine the previous shapes with the new shapes useing point attraction and random attracvtion in different sections, which I create 1.4. Have a quite large different in its sizes and distrucbution of the shapes, which I have apply this method with my final task 2 structure.
