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 type of fabrication techniques are additive fabrication, subtractive fabrication and formative fabrication. The computer Numeric Controlled fabrication were able to build phisical models from digital information. Thus is a building constructable or not will potentially denpend on the computability and those complex geometries that being described as NURBS curves and surfaces. This means that the construction is attainble by mean of fabrication progresses. This will llead to a more easy and accurate outcomes since Architects are able to know what they can building and their design will being send to be fabricated directly. By being accurate and able to make modifications easily, it is able to provide mass customization since it is able to create diffrent iterations at a same costs.

Week Three

Surface Creation

I find scripting is very diffivult at first, but after doing different panels, I began feel comfortable with it. Foer examole which the panel shown in the very left, I did not know how to construct a hexgonal grid panel using grasshopper where comes to a custom surface. But after doing some reasearch Iâ&#x20AC;&#x2122;m able to building this panel through panel connections. As shown in the other panels, I have played with different paneling attractors after the workshop. I tried to combone 2D and 3D surfaces during the process and finally end up with the first and second one of the left as my final design idea. As shown in the grid, I have made 2D and 3D grid separetely and then combined them together.

Week Four Panels & Waffle

I made the hexgon shape grid like this becasue I thought the structure of the waffle is very similar to a tree trunk where it act as the support and. Thus I was to manipulate honeycomb as one side of the panel. I make the top part of the hexagon have more height and gradually decreasing as it going down because I wanrt to make it similar to a honeycomb hanging on the tree. Also to make the structure like it is climing up to meet the other side. While the other side, I used triagluar shape as I want ot represent leaves and used truncated priramid as the braches. I used point attractor to make most of the triangles goes up to represent tring to meet the other side .

I made my waffle in this shape is because Iâ&#x20AC;&#x2122;m tring to connect the two surfaces together and makes it like the two surfaces is about to merge together to become one object. Thus there is one end is very close ot each pther and the whole structure looks like going upwards .

Week Four

Laser Cutting

The process of laser cut have went faily well. This time I put edges with edges and took some time to lay the nesting out and the printing resut is good while time is saved. I also turned some cut edge to etch so I donâ&#x20AC;&#x2122;t need masking tape,which have chance to damage the paper. When I used masking tape for the waffle structure some bits of the mountbouald is being damagin while tearing the tape. Thus next it etch is a much better way to do it. Also for nesting this time, I think I have turned to much cut line ot etch, it takes a bit time ot get it out.

Week Five

During the process of scripting my boolean form. I want ot use custom brep tp create the shape but through experimenting, I discovered that some time simple shape will work even better. Thuse for my boolean form I sticked with one geometry at every trial. Through the precess, I want ot created some thing that are distorted in position. Thus I tried the ramdom atactor. However, this attractor still works inside the grid, it position still havenâ&#x20AC;&#x2122;t being changes. Thus in the studio, tech tutor helped to solve this by using the script on the next page.

Week Five

Eventhough it said the volume have experienced error, but in reality, the script did work.

7

Week Five

This is the 4 boolean iterations I have done. I come up with this geometry using the script on the previous page where random value is used. I want to used a shape that have many edges so it can create many intersections which lead to much more possiblility. I tried the platonic Icosahedron in lunchbox first. And this come to the first boolean form. Where as I have expected, this shape does create intesting holes and surfaced because the number of edges and faces it has. The I tried the same shape with a smaller scale and difrent attractor points and this is shown in the two images at bottom. Then I tring thr Dodecahedron, this time I found the edges are two flat, it didnt create as much clear details as the Icosahedron do. When cutting the boxes, I first tried used the same shape as the cutter and baked out a Icosahedron from grasshopper for cutting. This made the cut blend well with the section being left out. However, when I trying using a cube and turn it arounf everytime when cutting. I find it gives a much more clearer and clean surface. thus I used the third one as shown on the right as my final design.

Week Five

Isometric

AMMMMMMMMMMMMMMMMMMMMMI choose this boolean form becasue the shape created many interests in the end. During the process, Iâ&#x20AC;&#x2122;m tring to make something that can linked wirth the theme i had with paneling. Thus when iterated the design, Iâ&#x20AC;&#x2122;m trying to make somethign that is going upwards ans provide some roughlooking texture. This iteration is the most fitted design where the cut outs leadig the boolean like it is going up and it also provided a tree-trunk like texture though the different sized pentagon. This model also adreess porpsity where there is a big hole opend at the bottom form a cabe like shape. Also holes are created at the top where light is able to shien though to light up the top area. While by openin a big gape that is about 1/3 of the area, it make the whole sructure permeability, even it has volume, it does not look heavy.

Task 01 Matrix When Iâ&#x20AC;&#x2122;m iterating task1, I dicided to do both face with 3D panels and 2D panels at the end. Before that, I have tried diffrenent attractors and shapes and discovered that it will be better if the both panels are organised in same way. This will give them a connection and able to related two different surfaces wirh different pattern well. Thus at the end, I choosed 4th iteration as I want to make the two panel have connections somehow.

Inorder to achiece a sense of unity while still contain differences, the traagular shape was used in as it is climbing up the waffle.

panels to be helfd in position..

The triangle was made as a slope to proved a gradual change for the size of the hexgon.

Design Matrix 1:5

Light is allowed to shine trhough the hole at the tap to light up the cave which adds to the interest.

Task 02 Matrix While iterating task 2, I preferred someing that is extrend out of the box so it create holes at the surface. Also I want ot make sure that in the middle there is many space that havenâ&#x20AC;&#x2122;t being cut out, and hope thre will be some interesting pattern come out. Thus at the end, I choose version I to develope further becasue It looks like the intersction of the faces make it create some patternes inside. The first one seems most unique in design as it is come out from a radom attractor wiith random rotation . The cut out shape create textture and add interest to the surface.

12 An open concave space is create bu the booleaned geometry which sphape of the geometry can be identified.

Process

I tried to rotate the gepmetry to add interest but there is too many columne and rows which make the leftover shape doesnâ&#x20AC;&#x2122;t look goood.

I tried to inclued more geomtry so divided each column by 5 however, It left a big gap between each column thus failed.what I wanted.

14

Appendix Process

I tried to used morph 2D mean, how ever the shape it created cannot be made since there is gap between each shape.

As there is gap between panels, this trail failed because it is not makeable surface.
