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.

Digital fabrication is a technique where the machine completing the fabrication, is under the instruction of a computer. This process is not limited to what an individual architect can physically draw and increases the opportunity of what can be constructed. This process allowed machines to have designs tailored to their functions and increased the capabilities of what these machines could produce due to this specific method. Two-dimensional fabrication relates to a cutting process to cause separations within a materials, examples of this would include laser beam and water jet. Subtractive fabrication is associated with the technique of removing material from a volume to form a specific physical object. This process introduces the concept of working in the z-axis and highlights the use of fabrication which is not limited by the X and Y-plane. In opposition to subtractive fabrication, additive fabrication relates to the addition of material to form a specific volume. The implementation of incremental layers to form a solid, often is used to developed models with curvilinear geometries, that otherwise would be difficult to fabricate using other methods.

Week Three

Surface Creation

Evidence of scripting to form surface panel, yet detail of the iterations are highlighted below.

Grasshopper scripting for surface 1.

Single panel iterations to find a surface suitable for the forms I intended to implement.

Grasshopper scripting for surface 2. The two main surface iteration differences is presented within the script. Surface 1 used morph3D actions to implement pyramids that pointed in two different directions. The surface 2 panel was formed using weaverbird picture frame, which increased the visability within the final form.

Week Four Panels & Waffle

The two surfaces present a pyramid motif. Surface 1 demonstrates how alterations to a surfaces texture affect how light and its shadows are distributed. Surface 2 highlights how controlled filtration of light can affect the pattern of the dappled light within a form.

The waffal structure highlights how the two interacting planes form a wing structure as the space is exposed on one side. As the two panels bend into eachother the space alludes to a shelted space and could be compared to walking within a canyon.

Week Four

Laser Cutting

During my initial stages of the urolling process I discovered that my meshs were not developable, yet I was able to resolve this issue and create these panels pictured left. I found that only some tabs faced the correct direction and therefore had to mirror the tabs in a different direction. In some situations I had to build the tabs myself, which I was able to achieve using the dup edge command.

The black lines highlight my cut lines and red symbolises the etch cut. After sending my lasercut file to the fablab I realised some minimal errors that I shall avoid in the future. My lables should be a smaller scale to reduce the time and therefore the cost of the lasercut. Another minor issue was leaving my tabs at 1mm thick, as it caused the actual construction of the surface to be challenging.

Week Five

Here is my script to form my final booleen form. I explored using cylinders, spheres, and altering the attrator point. Introducing a second attrator point assisted to create more variantion within the data.

Week Five

Isometric

The isometric shown highlights the three main differences in sphere size and therefore brings attention to the purpose of attrator point use. The model has a series of curved volumes removed from the original cube in a direction that extends from a set corner of the isometric. This forms a cave like approach that reduces the openess of the model and conveys a sense of low permeability. The sphere shape was favoured over the cylinder form as the outcome of the interecting forms was more dramatic with the curviture forms.

Week Six Task 01

Lofts Grid attractor Points Panelling Design Matrix 1:5

Task 01 Matrix During the iteration process, it was intended to highlight a space with openings and narrow spaces, throughout a single form. I realised that allowing parallel grid attractor points on one end of both surfaces to be close, the narrowing effect was created. This helped to emulate the concept of walking into a canyon-like space, which could be further translated into the next module to continue to explore this sense of adventure. The change in permeability within the surfaces highlight the reduced acces or lightin conjuction with the introduction of a dappled-light space which helps convey an intimate environment. This sense of privacy could also be evoked in the module three design.

Week Six Task 02

Task 02 Matrix The iteractions I explored included the alteration of attracter points to manipulate the grid and therefore affect the sphere distribution. I explored using two attractor points to create opposing sphere distribution yet I found that the use of a single attrator point was more dramatic. The sphere proved to create more intresting shapes when I reached the stage to form a booleen difference and therefore was favoured over the cylinder form.
