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

Kolerevic described three fundamental types 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 listed three types of frabircation: Subtractive fabrication, Addicitive fabricaiton and Formative Fabrication. Subtractive fabricatin is a mean to remove volum of material from solids by miling process. there are limitations on the object due to the axial movement of the milling machine. The addictive fabrication is to form a model by adding material in a layer by layer fashion. There are various materials such as a liquid polymer, and curing processes based on light, heat or chemicals. Formative Fabrication is applying heat or steam to material into the desired shape through stresses, such as compression, tension. Compared to Subtractive fabrication and addtive fabrication, the formative fabrication could be employed by large scale work with Computer Numeric controlled system. Computer Numeric Controlled fabrication ensures accuracy and efficiency when constructing a building designed with parametric modeling.

SURFACE AND WAFFLE STRUCTURE Surface Creation

The script of two surfaces starts with constructing a cube and selected edges by Debrep command. Then use List items to select the curves, divided into five points and points were exacted. Line command is used to draw the lines from these points. Then the surface is generated by Loft command. The different composition is made by testing various constant. Surface Domain Number is used to create a 5x5 grid on the surface. To verify the height and direction of the panel units, Offset Grid is adapted to lift the grid off the surface and Point Attraction command is to adjust the orientation of the surface. To make an opening on panel, i used weaverbird picture frame command which could adjust the size of the opening. Then insert the original grid, moved-grid, panel units into the Morph 3D. To apply two panels into one surface, I tried dispatch command for 2D panel side, the alternative could be Cull pattern command. It works on the value True or False you set. When input true, it keeps the pattern. When it is False, it culls the pattern. Then Entwine the output which group these 2 panels together.

SURFACE AND WAFFLE STRUCTURE Surface Creation

Given the suggestion from the workshop and tutorial, I did not make these two surfaces intersect with each other. They all preserved in an individual, boarder-clear order. Also, most of the surfaces touched the ground to make sure the stability. They all design on a curved surface but not too twisted. The in-between space is considered to avoid to be too narrow which prepared for the next waffle structure.

Isometric View

The waffle structure twists itself with an open top, allowed a large interior volumn.

Solid panels create a boundary between inside and outside. The open panel allowed more light into the space. Combine of solid panels and opend panel creat interesting experience through light and shadow.

The panel creats a geometric pattern which radiates from the middle as I set the point attarctor in the middle of the surface.

These two partterns designed in a chessboard feature and the echo with the waffle strcture.

SURFACE AND WAFFLE STRUCTURE Laser Cutting

The 2D panel with openings which is done in rhino while the 3D one is created by using weaverbird Picture frame in Grasshopper. It could control the size of the opening. The constraints would be it will create an opening at every face of the individual panel. The other 3D panel designed with two pyramids, then surfaces were overlapped when I unrolled them. I have to split them into individual pieces which increase the workload for making physical model.

Bacially, I varify the different way to construct two panels into a surface by Dispatch, CUll pattern. I also tried sift Pattern command when doing the matrics. It could select specific units based on the list you set for True and False.

SURFACE AND WAFFLE STRUCTURE Photography of Model

The triangulate panels that undulate along the curved waffle structure. Through the combination of closed and opening panels, the voids are generated. The sunlight could be able to flitered into the interior spaces, and the shadow would be differed by the surrounding angular structure.

Visual Scripting of Parametric Model

For scripting task 2 model, firstly Deconstruct Brep which make divide the 150x150x150 cube into nine cubes. I insert Point Attraction to manipulate the interior structure of the cube. Then I use volume to fine centroids. Then I use Rotate and XYPlan command which rotate the boolean units based on the attractor point and centroid. To verify the boolean units, I used LunchBox plug-in to test different design, such as Platonic Icosahedron, Platonic Octahedron. Sale NU command was used with remapped the distance between reference point and centroid.

SOLID AND VOID Surface Creation

I tried different boolyean unis, such as Platonic Icosahedron, Platonic Octahedron, sphere. I used clipping plan to find the interesting small units I want. I select one unit from sphere design and sent them to 3D printing as pricatice. Then I developed 3X3 grid into 5x5 gird because I found that it would create more dynamic interelationship between soilds and voids,

SOLID AND VOID Isometric view

I choose the Cube Boolean units as it creates a dynamic interior space for the whole cube. I rotate the boolean units in XY plane using the input of a point attraction and the centroids. Rotation of the base geometry based on the volume creates various intersections between spaces. Due to the feature of the cube and the direction of the rotation, the interior space creates dynamic spaces with the still flat ground at a different height which differs from other design made with rhombus or sphere. The variation of voids creates a rhythmic movement. The thresholds were defined by the intersection of the voids. The idea of porosity was an emphasis by the angular and harshed solids. The permeability addressed by the continuous of the voids. The section was made by Clipping plan, intend to show the interior volume which shaped by the voids. This isometric shows the full gird square whereas the 3D print was a smaller fragment while the angular and dynamic spatial feature could still be seen.

I tried 3X3 gird for the first matrics, Varify them in different attarction methods, different girds and different boolyean units. First Matrics is in 3X3 grid and second page was made by 5X5. Some of them are too large which did not Boolyean sucessfully Which need to be rescaled.

SOLID AND VOID

Photography of Model

As I stated before, after tring the pricatice printing I decided my later model on 5X5 grid which creates more intersting relationship between voids and solids. The one I ceate with Platonic Icosahedron is very similar to Platonic Octahedron,This may result due to I adjusted trucation value of the units. The one I create with Cube is more preferred than others. It creates intresting in-between space and set boundary naturally of private and semi-public space. I choose these pieces and sent them to 3D printing as they leave enough interior voids space for permeability idea.
