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)

The three fundamental types of fabrication techniques in the reading that Kolerevic described are additive, subtractive and formative. Additive fabrication is the process where the model is analyzed as two dimensional layers. The model is created by incrementally adding material layer by layer. Subtractive fabrication is the process in which the milling head removes mateiral from the volume along x-axis, y-axis, and z-axis. These two fabrications use â&#x20AC;&#x2DC;sliceâ&#x20AC;&#x2122; technique to process the information and transfer it to the information. On other hand, formative fabrication uses various mechincal functions to create the model from the material. Some of them are restricting the forms or reshaping the material with heat. Computer Numeric Controlled fabrication with parametric modelling is a method that connects the conception and the construction process. In return, it allows the designer to have direct control throughout the design process allowing and amplifying creativity process. To be definite, this results in a range of various design ideas and solutions.

SURFACE AND WAFFLE STRUCTURE Surface Creation

Surface structure is created by dividing 150 x 150 x 150 box in to 12 edges with 10 equally distant points on each. From the multiple possible configuration of the given circumstances in label 2, a combination of edge to point: (0,5), (5,2), (2,10), (9,5), (0,5), (5,8), (2,0), and (9,5) is selected. Shown in the label 3, surface on each side is divided in to two parts. Edge rows and most middle is one combined surfaced and two middle is the other combined surface. Waffle structure is divided between the rows and columns in the sections 2 and 3 using the shift i and shift j of morph 3D, and dispatch with gene pool. The fins of these rows and columns are created in the section 4 and 5. Section 6 trims the fins of the rows and columns combining them in to one structure.

SURFACE AND WAFFLE STRUCTURE Surface Creation

Image 3 Image one shows the first random testing of the parameters of the rhino with its given condition of choosing among 10 points of 12 edges. Since it is a experimentation, it is a mediorce layout with a rotating curved surface. Image two is a follow up of the idea of the curved surface from image one. To make the two surfaces connected as one, they are touched on at least a side. However, it is too wide apart and and impractical for my design. Image three is the final design that uses finding from image one and two. Keeping with the rotated curved surface and maintaing a flowing one surface by connecting two of them, the layout from the image 3 is established. It is both wide apart and closed to each other on their opposite position creating illusion of a triangular openings. Structurally, these openings provide sunlight for the structure and ventilation making this an efficient design.

Isometric View

The two surfaces are similar with the difference of the direction that the panels are attracted towards. In addition, the openings of the panels are alternated to provide light penetration or stack ventilation with each panel.

Waffle structure maintains a symmetrical layout with triangular inverted opening on each side. The purpose is to provide a smooth transition between the openings for movement, wind and light. For instance, the inverted opening is the balcony and other is glass facade with the entrance.

SURFACE AND WAFFLE STRUCTURE Laser Cutting

Laser cut for the model is extremely hard as the model has plenty of restrictions. First restriction is the tabs of the unrolled panels. To maintain the openings of the panels, the tabs have to be manually drawn. Second restriction is the small openings in the waffle grids. It is an issue when the most narrow part of the waffle flatsâ&#x20AC;&#x2122; openings try to accomondate the fins. The size of the opening has to be readjusted manually to allow the connection of the waffle structure. In general, it is a simple process.

Grid offset and attraction points are used to achieve a variance in the formation of the pyramids.

The inverted triangular opening from the waffle structure is opposite from the main opening. It creates an illusion of the shift in elevation with one side being narrow and other side being wide. While the front triangular opening acts as an entrance, the inverted triangular opening acts as a balcony.

It results in an illusion that these surfaces as moving organic structures.

The right square pyramids with openings are used on the surface of the waffle structure. The openings of the pyramids portray the structure as an organic strcture with its shifting pyramids.

A change in shift i, shift j, and combination of dispatch and gene pool allowed the alternating patterns of the pyramids. In return, it allows the pyramids to be seem as organic structural components. The openings of this pyramid is alternating from the previous rows of pyramids. As this patterns follows throughout the surface, it serves to create an illusion of the floor rotating. On this side, the opening is an isosceles triangle that acts as an entrance for the waffle structure. It serves as a foundation for the whole structure to be symmetrical. Moreover, it creates an expectation that the opposite side has the same triangular entrance.

Attractor / Control Points (X,Y,Z)

the parameter Attractor / Control Curves are attractor Grid Points points, shift-i and shift-j function of the morph 3D parameter, and gene pool of the dispatch.

The laser cut model shows the front and left side of the waffle structure with its surfaces. It shows the entrance with its triangular opening and the side panels with their openings. There is a variance of light penetration from the openings in to the structure from the structure as expected.

SURFACE AND WAFFLE STRUCTURE Photography of Model

This side of the model is the back and right side of the laser cut model. It shows the inverted triangular opening that takes in the light compared to the entrance as balconies do. More importantly, the openings are located everywhere that structually allow stack ventilation.

Visual Scripting of Parametric Model

Box 1 of the parametric model is modeling of the cube of 150 x 150 x 150. Box 2 of the parametric model follows up this cube with variance in attractor points and non-point attractors. Box 3 leads to the set up of the berps that is used for boolean difference with the cube.

SOLID AND VOID Surface Creation

The first image is the boolean difference and intersection of the original cube with two rectangular prisms that runs on x-axis and y-axis. It creates a simple cube with rectangular caves running on the x-axis and y-axis. The second is the boolean difference of the original cube with spheres. It creates a cube that has damages from numerous explosions at one side.

It is a simple iteration of the cube with the boolean interesction of the spherical volumes. Due to the simple boolean difference and intersection, the porosity and permeability of this structure is limited. It still maintains the original structure of the cube having only simple void fractions. Similar to the porosity, the permeability is present but static. It has similar dimensions throughout for the voids.

SOLID AND VOID Isometric view

It is dynamic iteration of the cube with a boolean difference and intersection of the volumes of a combination of sphere and rectangular prisms. The results are explosive void fractions throughout the cube. The porosity are infinite with different shapes of openings and different forms of openings. In return, the permeability is emphasized with various and different channels running throughout the cube.

It is a space where the points of the geometry that creates a gap. It produces an open space from the ceiling that bridges the space between inside and outside.

The booleaned geometry contained mostly within the original cube, but the cube is still highly visible with dotted lines.

The solids left behind by the boolean difference are space that is part of the structure. It represents as a negative space when compared to the intersected areas.

Intersection that are not part of surface envelopes produces private space. It is an enclosed space without openess to the outside.

The intersecting geometry produces a surface that engulfs the empty space. It creates a navigable open space.

The 3D model only the left shows a structure that does not define neither public and private space. It is an structure that gives shade to the people similar to the tree.

On the right is the model that tries to contrast the threshold of different levels. However, it is not successful because the floor is too high.

SOLID AND VOID

Photography of Model

The model on the left shows the success of dividing between the public and private space. Despite that, it is still ineffective in creative a threshold between levels.

On the right, the 3D model is successful with the division of space while mainting the connection to the outside. Also, it is a bit accomplished with threshold on different levels with its border of the foundation.

The laser cut of the surface patterns can be seen in the picture. However, this laser cut has a problem because the patterns contain tabs that are too small to glue to each other. It had to reprint again with bigger tabs.

Appendix

Process

The laser cut of the waffle grid is shown in this picture. As shown, it does not have any problem like the laser cut of patterns. The problem with small opening for intersection previously mentioned was not an issue.

Appendix Process

The 3D printings of the models are done in two trials to save time. It is effective as it does not create any conflicts with the models.

Appendix

Process

The 3D printed models are cleaned with sand paper and sand sponges to create a smooth models. Also, it is to make sure no filling is left.
