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)

Kolerevic expressed three fundamental type of fabrication techniques in the reading. Two-dimensional fabricatin where the cuting head moves on two axis, x and y, over a sheet of the material which can cut by using one of the following techinques , laser beam ,plsma-arch and water jet. The fundamental type of fabrication techiniques in the reading is the subtractive fabrication. It included the removal of a specified volumn of material from solids by using electro, chemically or mechanically-reductive process. Another techinique is additive fabrication which involves incremental forming by adding material in a layer-by-layer fashion, in a process which is the converse of milling. Futhermore, formative fabricationis also one of the fundamental types of fabrication techinique in the reading by Kolerevic. In formative fabrication, mechanial forces , restricting forms,heat or steam are applied to a material so as to form it into the desiredshape through reshaping or deformation, which can axially or surface constained. Computer Numeric Controlled fabrication has the potentialwith parametric modeling the data able to be imputed straight from thecomputer program into the machines computer in order to produce the end product . Removing any need for techinical drawing or manufacturing drawing.

Week Three

Surface Creation

With the use of Grasshopper surface script,( top iimage is to create edges of surfaces, bottom one is to make geometries in the surface ), four different type of surfaces iteraction has been created. This process is started by setting a 150 x 150 x 150mm bounding box to produce two surfaces. The edge of the bounding box is used as the parameter, then deconstruct BREP step is conducting in Grasshopper to get the edges . List item and divide curve are then adjusted to produce two surfaces with no intersecting. Using a script to create forms which allows it to be adjust easily, And many iterations can be create quickly and easily

Week Four Panels & Waffle

The panelled surfaces are made up of 3D panels. The left surface shows different height, use wavebird to create different size of perforrations for each solid panels, which create interest shadow when the light passing through. The small size of perforations and panels create a darker and more private space, bigger one allows more light pentrate in to provide a brighter and more open space.The right surface is flat than the left ,in order to make the volumn appears soften that create the balance for the whole volumn. 4

The waffle structure is like the skeleton of the whole model, which support the two surfaces and the panels .They are formed accoring to the shape of the surfaces, and appears distored. Smaller in the top of the structure makes the structure more private, and also increasing the space for the bottom. The waffle structure is hollow to give an opportunity for the creation of the interior volumn.


Week Four

Laser Cutting

Unrolles 2D and 3D panels for laser cutting after finishing the design in Rhino and Grasshopper. The image shows the unroll template for panels and waffle structure. laser cut file is prepare ed by separating the cutlines and etch lines into different layers by different colors. All the small pieces are labeled with number beside for easy model making.

The main concept used in this task is applied different geometries throughout the design to create more variations. It is started by subdividing a 150 x 150 x 150 mm bounding box into 9 cubes to get the subdivided cube as the primary parameter. Point attractors used to manipulate the grid and transform the shape in order to make different variables of shapes with different sizes. However, the grid centroid is applied for the shape distribution, in order to maintain the consistency of the shape arrangement . The boolean script in Grasshopper is shown above to provide evidence of the design process.

Week Five

Isometric

The boolean solid is about 1/6 of the volumn of cube to be 3D printed. The iteration process included trying out with the point attractor to get different shape distribution of the grid. Futhermore, the scale of the shape is adjusted as well in order to obtain differenr size for shapes as variation. The chosen iteration was primary design with Pentagonal pyramid shape together and scaling as the boolean effect. Next, the boolean structure was future boolean again like zigzag in different angles, to obtain the most intereting 1/6 volumn of the cube. Lastly, applied another iteration to boolean the solid to make it more attrative, Like pipes link two pentagonal pyramids to create a secret space, Squares to emphasize the threshold. The main design concept for the final boolean solid is to create a pavillion structure. The final 3D print solid boolean is like a recreational facilities. Pentagonal pyramids shapes interact each other to create the pathway for people to walk through, and multi surfaces of pentagonal pyramids also make more possibilities for circulation. Different size of pentagon in the top of structure allows light enter into the solid, and dinstinguish the private and public space, darker area more private, and brighter area more public. It also can create interesting shadows. Zigzag cap gives opportunities for hold activities in there. Futhermore, the top view of the structure looks like a “heart� shape, which recalled the notion of the design, provide people a place where full of love.

Design Matrix 1:5

Solid panels create a definitive boundary between exterior and interior. More flat panels makes the volumn appears soft,

Different size of perforations create variation for shadows.

Perforations allows light enter the volume, different size of perforrations for every solid panels create interest through light and shadow.

Task 01 Matrix

Matrix 1.4 is the group of surface chosen from interation. These surfaces combine both curve and flat surfaces which is interesting to be future developed. After i tries out with point and curve attractor, the final decision(matrix 2.4)was to stick to the regular grid as the surfaces which is originally curvy, and it will not be add more complexity to the panels forms. For the paneling surface( matrix 3.4), i use weaverbird’s picture frame to change the size of the perforations for each panels, and also adjust the height of every vertical row of panel.

Perforations on two panels allows the winds circulation through the volumn

The size of Perforations and Panels are smaller at the short side of the volumn, to create a darker and more private space.

8 A hollow waffle structure allows for the creation of an interior volume. The rotate surface makes the vol-

Perforations and Panels are bigger at the wide side of the volumn, allows

Task 02 Matrix Four interactions had been made as grid maniputation by using point attractor. 1.1was chosen to be main developed as it shows the best manipulatin and greaterpotential. By using point attractor, diffrent shape distribution was obtained. Matrix 2.1 was chooesn because it provide a more consistent distribution , that is suitable for the geometry used for booleam. And after booleam 3.1, i makes more different shapes(matrix 3.2/3.3/3.4) and use same methods to booleam.
