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)

There are three fundamental fabrication techniques that were described in the reading: Subtractive, additive and formative fabrications. Subtractive fabrication is very much like sculpting, it works by removing a particular volume from a larger piece to create the desired shape. Typical additive fabrication like 3D printing is very common in the industry, it involves incremental forming by adding materials layer by layer to a base. Lastly, formative fabrication involves heating up specific materials to the melting points and reshape them by pouring them into a pre-fabricated mold. The Computer Numeric Controlled fabrication with parametric modelling has a great potential in which it is able to create mathematically accurate models in a very fast pace as it can be modified and used to create iterations with ease very quickly by simply tweaking the numeric inputs.

Week Three

Surface Creation

The lofting process was fairly strightforward, with the help of Grasshopper I was able to generate various lines very quickly. I copied the script above and labeled the second one as the second surface so I was able to visualise both surfaces at the same time to find their best interactions.

Week Four Panels & Waffle

Simplistic 2D + 3D panels allowing light to come into the internal space freely. Peek holes also allow viewers to see through the panels horizontally and depict the flow of the surface.

Waffle structure simulating the shape of a tent, provide a shelter-like space for the visitors.

Week Four

Laser Cutting

Images on the right depicting my laser cut file, where red represents the etch and black are equal to cut lines. To avoid being fully cut by the laser cutter, I did the etch in dashed lines to prevent that from happenning. I also send in the file with my friend together for saving money purpose. The biggest mistake I made was forgetting to mirror the lines, which forced me to fold the panels in a reverse direction.

Week Five

On the script above, orange components represents the variations that I used during the parametric modelling process (such as weight attraction, curve attraction and point attraction). I aimed to create more than one geometries and somehow manage to find a balance in the volumes they have. In order to achieve this, it was important for me to firstly pick the right geometry with a well-balanced form. I have also tried to explore different transformations apart from scaling, however, the end results look eith too condensed or lacking diversity, which led me back to the slight scaling again.

Week Five

Isometric

My aim when designing this 3D model was to create diversity yet with a balanced/symmetrical form. When picking which geometries to go, I tended to choose the ones with balanced forms such as spheres and icosahedrons. I was then really happy with the individual results they could produce, however, the final form was still not as impactful and interesting as I expected. At this point, the idea came to me: “Why not try using multiple geometries together?�. I tried it and the result then was very rewarding, I was able to find a well-balanced geometry but still with very interesting visual forms. The final 3D print addresses a strong sense of porosity, about over 50% of the volume were booleaned out, while the other 50% creates a strong visual impact while allowing light and air to permeate through. Overall, the model is simplistic looking while remaing its unique complexity with multiple geometries involved.

Task 01 Matrix In the task 1 I ended up using the surfaces from 1.2 as the other three options can either lack variety or create doubly curved surfaces that could potentially affect the unrolling process. For the final outcome I picked the 3.2 for it includes both a 2D and a 3D surface, which shows a much more diverse solution comparing to the others. 2D panels also allow more light to come into the structure.

Task 02 Matrix For task 2 I ended up using a point attractor to create both the grid and internal volume centroids. Point attractor although do not create dramatic effects like curve attractors, it is a great tool when it comes to creating balanced and evenly spread patterns. In this task I aimed to create a dynamic yet well-balanced result, therefore I picked 3 dynamic geometries and boolean them together to reach the final result.

3D Model Trials

My explorations on how differnt panels create diversity on a variety of different surfaces. Most of them failed due to doubly curves surfaces and some simply lack diversity.
