Materials
Modelling
-
-
-
Plasticine: used for children's play and as modelling medium for formal/permanent structures, non-drying properties -putty-like
Paper
-
-
-
Layout paper: -useful for designers to lay over top of existing drawing to trace -multiple layers on top of eachother appear as one -40/60gsm
-
Boards
Corrugated card: -one/two outer flat layers + corrugated layer
-used for packaging -lightweight/strong/smooth/easy to print on
Duplex board: -two layers + wax coating on exterior for moisture barrier -smooth/glossy -suitable for offset printing/cutting/folding -200/500gsm
Foil lined card: -stiff lined card with aluminium foil on one side
-waxy coating so resistant to oils/liquids -food safe
Inkjet card: -used w/ inkjet printers -ink sits on smooth surface w/ even coverage/absorbency -matt/gloss coating
Foam core board: -polystyrene foam in middle/rigid+lightweight
/cuts cleanly -used for backing material/architectural prototypes
Solid white board: -strong smooth surface -used for book covers+packaging -accepts printing/surface finishes -200/500gsm
Textiles
Cotton: -comes from 'boll'/mature seed splits open revealing fibres which then get spun into yarn -strong/soft/easily washable
Wool: -can be coarse or soft -absorbs vapour+keeps dry layer of air next to skin -easily spun/woven knitted/crease resistant/absorbs dyes
Silk: -raw sourced from cocoon from larvae of silkworm -triangle structure gives shimmering -soft/drapes/retains shape well
Modern
-
Polymorph + coolmorph: -polymorph fuses at 62°, coolmorph at 42° -can be coloured/reused/remoulded -hand mouldable
-
-
Fibre optics: -used for cable TV/broadband infrastructure -medical applications (endoscopes)/fun optoelectronics/novelty goods
-
LCD: -monochrome or full colour/needs backlight
-small/lightweight screens -bespoke monochrome layouts
can be achieved -low power consumption
Metal foams: -lightweight -air pockets made by injecting gas in liquid aluminium/titanium -100% recyclable
Smart
-
Photochromic particles: UV light reacts w/ photosensitive silver halide particles -prescription glasses that darken in light
Photochromic pigments: -present UV light stimulates particles in a special pigment -noveltygoods/paints
-
Quantum tunnelling composite: -polymer w/ billions of metal particles -insulator/semi-conductor -pressure applied allows electrical signal
Piezoelectrical material: -changes from movement/stress producing electricity -attach electrical signal to it
Piezo transducer: -thin layer of piezoelectrical material
-tranducers vibrate when electrical signal is sent -when spoken into/tapped produces electrical charge that can be amplified into a trigger
-
Moulding + Forming
Blow moulding: -plastic inserted in mould, air is injected, plastic expands -bottles/cotainers
-
Injection moulding: -molten material forced in close mould under pressure -plastic melted w/ built in heaters -buckets
Vacuum forming: -mould put onto vacuum bed, theroforming sheet damped above vacuum & heated until soft, vacuum bed lifts close to sheet, air sucked out under, air pressure forced plastic into mould
