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 types of fabrication techniques which Kolerevic described are additive, subtractive and formative Fabrications. Addictive fabrication like its name suggests is where you add more material from the original piece of material using the CNC Router. Subtraction also like its name suggests is when you use the CNC router to carve out excess material to accomplish the desired shape. And finally the formative fabrication, formative fabrication uses steam or heat to assist in reforming the material with the CNC router. Although CNC router is vastly versatile but there are still many factors that held it back when compared to more advanced fabrication techniques such as 3D Printing and Robotic Arms. The CNC Router is limited to the processing power of the computer its controlled by, the size of the router and the amount of axis it has on the router. Though the precision of the CNC router enabled us to be able to model complexed parametric models and save enormous amount of time and man power.
When Grasshopper was first exposed to us it was a bit comfusing, but luckily that quickly shifted around with the help of IDDA tutorials and workshops. By using the code we have learnt from workshop in Grasshopper, I was able to create various different surfaces that I could potentially work on. The process was fairly simple, by using sliders created in the code i was able to adjust the 4 vertices of the surface along the edges of the 150x150x150 cube with set distances. I created multiple surfaces for further testing.
Week Four Panels & Waffle
My design inspiration in creating the pyramids was based on how the Egytian pyramids created complexed shadows as the sun moved above it. Also, because it is a closed pattern which would be interesting to see how it effects light and shadow in the waffle structure. The â€œVolcanosâ€? as I would like to call them was inspired by how it would allow light to pass through while also creating complexed shadows as light is reflected from its many surfaces.
The waffle structre has curves that is formed from the surfaces. The waffles structure ensures that the 2 surfaces connected are within the boundaries of 150x150x150. The waffle structure itself is sturdy and resembles the foundations of a building. The hollowness of the structure also allows light to pass through.
The Laser cutting preparations was created after the design of the entire structure and panels were finalised. I first trial and error to see which ones of the panels will unroll together. After both surfaces were unrolled I used Grasshopper code provided by LMS to create tabs for the panels so that they can be glued when printed. Then I used Grasshopper to create the slots for the Waffles interlocks and also laying out each layer flat when its numbered. Then I would import my work into FABLABs laser cutting template and ensure that all my folding lines are etched and all the cutting lines were set correct. I also Etched the numbers of the panels into the material so I wouldnâ€™t be lost while making models. In conclusion, it seems that Grasshopper is much faster and more accurate.
All the initial setup and code for Grasshopper was learnt from Workshop. After experimenting various part of the codes to create different Boolean structures I created multiple itterations of the structure I might use for the final design. I have used different shapes, played around with point attractors and also modifying the grid until I get a interesting enough model that I was satisfied with. The images above shows some of my design itterations.
I eventually settled on the 5x3 sphere design that was a perfect balance of interesting aspects and practicality. The final result appeared to look like a block that was panetrated by a rifle multiple times. The shape was achieved by cutting the cube into 8 right angled triangles. The way I cut the structure allowed me to show more uniqueness of the structure as it cut through the spheres in complete different angles. The finishing product was both aesthetically appealing and interesting. It conveyed complexed shadows and reflections from lighting, showing multiple shades and creates an illusion of multi-colour. My idea behind the design was to create something that explored the complexity of light and shadows and I believe it is safe to say that I achieved what I wanted. The structure also resembles a shelter of a like which I could even potentially see it being used as a sort of pavillion.
Week Six Task 01
Task 01 Matrix The matrix is basically my thinking process on how I eventually developed my structure to the final stages that it is. Each different itterations are basically prototypes of potential final designs. I eventually settled on the one that is more balanced in both interesting aspects, practicality in making the physical model and aesthetics.
Week Six Task 02
Task 02 Matrix The idea behind this matrix is identical to the previous one. It shows my design process on how I eventually settled on the final design that I have now. When I design structures like this I always look into the aesthetics of the structure, the complexity of the structure, and finally the possibility of the real product. In this case, I also chosed the structure that was well balanced, not too boring, not to hard to manufacture and not too complex.
Final Isometric Views
The Pyramids casts shadows on each other creating different shades of colour on itself
Experimented numerous ways on attaching the panels to the waffle structure. Superglue and UHU glue failed and I succeed with foam ducktape. Though the downside is that not you can’t see through the structure anymore.
The Waffle structure failed to lock tightly together had to glue it with super glue

3D printing of the Boolean structure did not come out perfect but was good enough to show every detail that was important.
