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)

Advancements in technologies and processes has allowed for the ability to produce faster and more accurate models and prototypes. to more clearly convey the key elements and overall design of a product. Three techniques that have had great influence include 3D Printing, CNC Routing and Laser cutting. Each technique serving extremely different functions provide architects and designers to clearly and effectively communicate through visual representation.


Week Three

Surface Creation

The development of the above surfaces was achieved through the use of Rhino and Grasshopper modelling software. Lofting surfaces through the generation of lines created by through grasshopper has allowed for the generation of 4 unique combinations of surfaces, each with their own strengths and interesting factors, to be later represented through 3D paneling.


Week Four Panels & Waffle

Paneling was achieved through the generation of paneling grids and selective breps. The use of grasshopper software enabled the 3D paneling to be easily achieved and modified throughout the design process.

The interior structure was designed as a functional aspect of the design in order to give the design strength and stability as well as sturdy anchor points for the 3D paneling to stick to.


Week Four

Laser Cutting

Two sets of laser cutting files were produced in the generation of task one, Minimal efforts involved in “nesting� were required as the minimum material size exceeded the required surface area for both the waffle and exterior 3D panels. Panels were achieved through unrolling surfaces to creating 2D nets that can be folded to produce 3D Panels. By making 2D lines and separating each onto cut and etch layers I was able to clearly and effectively send information to the laser cutter which intern was able to cut the Waffle structure and exterior panels.


Week Five

Scripting was used to develop the task two design, Through exploring scaling and location through the use of attractor points and lines a unique design proposal was developed that enabled the clear demonstration of skill and knowledge of rhino and grasshopper.


Week Five


The isometric as seen to the left was developed through a combination of software and function in order to produce and interesting and unique collaboration of structure and void, The method of boolean enabled the design to explore interesting shapes and internal structures. The lattice like internal support structure was developed through the generation of the structure as geometry before being Boolean from a simple sphere which was then manipulated through the grasshopper software to produce the design as seen. The spatial qualities in the interior and exterior spaces of the design creates interest and intrigue.


Week Six Task 01

Task 01 Matrix As seen above a range of interactions were developed in the process of producing the final design. each option provided the design with its own interests and challenges in physical modelling of the design. –

Task 02 Matrix As seen above, a range of design options were developed in order to produce the best design possible to clearly and effectively demonstrate the skills and knowledge associated with the development of the final 3D printed design. Clear emphasis was taken in the section at which the final cut would be taken from.
