7.1 Flashcards
what do models do
add to drawings
hwo do models add to draws
as they add to
communciating
visualising
testsing
what do models allow
testing ideas to optimise designs and help stakehodlers to udnerstand an evaluate
what are prototypes
a functioning or non fucntioning pre prodcution design evaluation modl
what can models mae from a rnage fo materiasl adn compoenets be made to use
block models
working prototypes
what can be doen by creating block models and working protypes
easier communciation
testing of ideas
structural intergint
what are teh 3 key thinsg mdodelling does
saves times
redices mistake
avoids expense
why are intial 2d and 3d sketches usseful in early stages
no need to consider finish
allow for checks on fucntion and size
easy to visualaise
udnerstandab,e to cclients
why may mroe detailed models be needed in the later designing process
exploration of aesthetics
development of techinacl eleements
consideration fo moulded parts
what are the ypes of mdoels
block
working
what are workign models
models that test mechansim and componenets
what ar block models
models that dont work btu show appearance and haev a high standard realsistic finis
what are the types of processes sue din mdoeling
additive
subtractive
how can model making process be made simpler
use of cad and cam programmes
how does cad and cam make shit simpler
easy to create high detail quickly
can eb sent to 3d pritners to make
tools to cut with
craft knife
scalpel
junior hacksaw
toosl for adhesives
glue guns
solvent cement
materials used in cuttign mdoelng
foam
card
corregated card
balsa
styrofoam
HIPS
what si handforming pliabel matrials
where you moudl with hands to get desired shape
materials used in hand formign
clay
plasticicne
polymorph
hard wax
speak abotu polymorph
can be machined
can be reformed
strong enoguh for mechancial parts
what would be used to test circuits
bread boards
electonic kits
whats used in circuit testing, specifclally
copper wire
clip togetehr kit compoeents
benefist fo compeoents and kt elements in cirucit testing
fit togetehr withotu soulder
what type fo modelling woudl metal wire be used for
wire cuttign bending and joinign
how may metal wire be joined
adhesive tape
epioxy resin
soldering
what does metal wire mdoelling allow
frame works of varying complexity
materials easily soudlered
copper and rbasss
wire easy to manipulate
aluminium
where woudl sheet polyemrs such as HIPS or acyrlci be used
thermofroming -
vaccum forming
blwo moulding
what does tehrmoformign facilotae
more compelx 3d forms
what materials used in CNC laser cutiting
card
plywood
mdf
polymer sheets
beenfist fo CNC cutting adn engravign
make complex shit pretty eaisly
what materials used in etxtile mdoellign
calcio
rip stop nylon
where woudl textile mdoellign be sued
fabric elements fo design
what si rapid prototypign
use fo machiens such as 3d pritners to proce realsitic 3d mdoels from cad data
adv of 3D printintg
innoavtive
compelx designs
quick
low costs
many cad programs linkied
range of aethtcis
con fo use fo 3d pritnign
may need hand finsihign ]
what do rapid prototypign technologies include
FDM
3D body scanning
SLA
MJM
SLS
what is FDM
fused deposition modelling
what does FDM do
builds up layers of polymer to create parts
what is SLA
stereolithography
what does SLA do
uses UV lasers to solidfy layers of light sensitve resin
when is SLA useful
applaictiosn such as pottery modelling
what is Mjm
multi jet mouldign
what does MFM allow
very high quality finish
what does SLS do
uses a laser to fuse pwodered material itno solid materials
geenral pros of 3d printing
cheap
effectiev
quick
complex desigsn
flexible
create lgihtweight parts
gerneal cons fo 3d pritning
limited materials
limited size of shit
finsihing needed
high cost per unit on mass production
can be weak strcutrue
soem can have low toelrances
copy right issues
adv of digital simulation
tiem and cost savings
easy to shwo to stakehodlers
easy to fully design 360 viiew
rapid modifcations can eb taken place
ways that digtial sim maeks shit easier to show stakehodlers
