What are the benefits of prototyping?
can be physically handled by designer + team
scaled prototype - work out the method of manufacture
determine the ‘flow’ of production on a production line
errors are detected w a prototype and then can be solved
display it at meetings - visual feedback
Why do we prototype before manufacturing a product?
to help determine whether your idea will work or needs to be modified
to test your solution quickly and cheaply
gives oppurtunity to get client feeback
What can we learn when prototyping?
whether proportions of the product are correct
the functionality
aesthetics and materials can be assessed
Why is prototyping important in the design process?
allows designer to make modifications to ur product before manufacturing - saves money and time
helps u to follow the iterative design process
What can be used to make a prototype?
cardboard/corrugated card
blue Styrofoam
MDF
CAD software
Why is cardboard suitable for prototyping?
cheap material
available in different thickness
easy to cut, score, bend and join
easy to make quick adjustments
can be laser cut from CAD drawing
recyclable
stiff structure
lightweight - easy transport
What does MDF stand for?
Medium Density Fibreboard
How is MDF made?
made from wood fibres glued under pressure and heat
Why is MDF suitable for prototyping?
rigid, smooth and has no grain
easily machined - cut, sanded and filed without damaging the surface
inexpensive
range of thickness
can be glued with wood
Why is Blue Styrofoam suitable for prototyping?
easily cut using a hot wire cutter
sanded into all shapes using common tools
easily joined with PVA glue or tape
shaped into complex forms (curves)
cheap and available in range of thickness
quick to work with
u can add imprint and detail
What is rapid prototyping?
fast fabrication of a physical part, model, or assembly using 3D CAD
what does CAD stand for?
Computer Aided Design
Why is rapid prototyping important?
companies need to develop and introduce new products faster to stay competitive
What are the advantages of rapid prototyping?
can manufacture complex designs quicker
quicker than modelling by hand
early stage design of form, ergonomics and function of the design
allows functionality testing
changes can be made quickly
give the use hand - on user experience for feedback
why is 3D printing often used for rapid prototyping?
allows designer to realise a physical idea quickly from a CAD drawing
Can be tested and modifications easily identified
What are the disadvantages of rapid prototyping?
very expensive to manufacture at a high quality
restrictions on build size
limited material range
What does CAD stand for?
Computer Aided Design
What is CAD?
the use of computers to aid in the creation, modification, and analysis of a design
What are the advantages of CAD?
__F__ixes errors quickly
__I__mproved versions of designs
__S__timulate how a product will look and preform
__C__ollaborative design - designers can collectively work on projects globally
__G__enerative design - use maths to create better designs
What are the disadvantages of CAD?
__L__oss of skilled workforce
__H__igh set up costs - equipment software, staff training, machine maintenance
__C__yber attacks - viruses can cause problems
What are examples of CAD programmes?
2D design
Autodesk fusion 360
What does CAM stand for?
Computer Aided Manufacture
What is CAM?
an automated way of manufacturing products, using computer-generated code to control the machinery
What are the advantages of CAM?
__R__epeated manufacture at high outcomes
__C__ontinuous working 24/7
__R__apid prototyping
__S__peeds up manufacturing process
__M__inimal supervision
__H__igh degrees of accuracy
What are the disadvantages of CAM?
Outdated - technology can be outdated as it moves forward
Loss of employment
Technology can fail - cause accidents
High cost - equipment, training and maintenance
What are some examples of CAM machinery?
CNC embroidery
Vinyl cutter
Laser cutter
3D printer
