PROTOTYPE #1FROM M2
-feedback from M2 presentation:
-MDF vs polypropylene
-MDF produces a sense of solidity and stiffness -polypropylene seems to be effective to generate lighting effect
-lack of contrast
-not delicate
-joints/binding material needs to be changed

READING RESPONSE WK 6 Architecture in the Digital Age - Design + Manufacturing/ Branko Kolarevic, Spon Press, London c2003 -3D scanning
-translation from physical to digital through a three-dimensional scanner and it involves not only physicals
but also site surrounding environment -digital fabrication: from digital to physical
-facilitate by programmed machine to produce a more accurate and higher quality outcome
- 2D FABRICATION
-CNC cutting that includes various fabricating technology such as laser cutters
-subtractive fabrication
-removal from solids with calculated volume of materials – 3D milling cutting
-additive fabrication
-the formation of adding material in a certain order progressively – the converse of milling
-formative fabrication
-formation into specified shape through reshaping and deformation with external forces such as mechani-
cal forces, restricting forms, heat or steam etc -assembly
6
-using 3D models to determine the movement and location of required component
READING APPLIED TO DESIGN
How does the fabrication process and strategy effect your second skin project?
-we use laser cut to fabricate our models -unroll the three-dimensional model into 2D surface for fabrication -break the complex form into small pieces -when assembling the model, we use digital model to help locate the position of each piece
7
PROTOTYPE #2
-LASER CUT -MATERIAL SELECTION -- CARDBOARD
8
-in order to test different skin effect, each prototype module is enormously enlarged in scale -three different types of skin/infill are planned to be tested -hollow
-hollow line pattern
-radial thread pattern
-color test -- BLACK vs WHITE
-same module but fabricate in different colours
-different effect
-BLACK is considered as the more successful and effective colour than white -white seems to be a bit plain on human skin -black provides stronger contrast with skin and hence is believed as a more effective colour -the contrast between black model and its shadow tends to create a sense of mysterious effective -black works better with shadow--lighting effect -thread patterning creates better complexity and seems to be more effective than hollow line patterning

READING RESPONSE WK 7 Digital Fabrications: architectural + material techniques/Lisa Iwamoto. New York: Princeton Architectural Press c2009
Describe one aspect of the recent shift in the use of digital technology from design to fabrication? Digital production is able to narrow the gap between design representation and the final outcome, building, affording a hypothetically seamless connection between design and making. But as with any design process, digital practice comes with its own restraints and possibilities. Digital fabrication streamlines production, blending upstream and downstream processes. 3D digital modelling and digital

fabrication are able to energise design thinking and expand the boundaries of architectural form and construction. Digital fabrication expands roles of architect to include oversight of building and construction management process.

-SINGLE TAB--POLYPROPYLENE

-EYELET-4mm

PROTOTYPE #4 -- MATERIALITY -- FABRIC INFILL
-the selection criteria of fabric materiality involves following consideration: -opaqueness -thickness -transparence -flexibility -elasticity -resilience
14
TEST EFFECT OF FABRIC -fabric can produce a sense of texture that pattern threads cannot compete -fabric can coporate with light effect well -however -fabric does not match with our poly bone frame -fabric decreases the sense of mysteriousness we tend to create -hence -fabric will not be used in final project
15
PROTOTYPE #5 -- DENSITY
-the four pieces are the same in scale while fabricated with different density of the holes -the density of holes indicates the variation of thread pattern -refering to our design intent, denser pattern will be used for depicting more intimate and sensitive personal space
