- The six r's
- Refuse
- Issues relating to sustainable design
- Refuse to use some types of materials
- Reduce
- The life cycle of a product
- Built in obsolescence the product is built to break
- The amount of materials wasted
- Repair
- Some products can be repaired and then reused
- Some products cant be repared and have to be scraped
- Reuse
- The product can be reused for the same purpose or a new one.
- The product can be adapted for a new purpose
- Rethink
- Can you use diffrent materials and procceses to create your product
- Reuse old and broken products to make brand new products
- Recycle
- Materials that can recycled
- The materials can be reuses from disassebled products
- Can be used to make brand new products

- Processes
- Line bending
- It invlves heating a material along a heated line.
- The plastic softens as it is heated allowing to bend and as the plastic cools it will retain the shape.
- injection moulding
- Injection moulding involves heating a polymer until it is a liquid it is then forced into the mould under pressure.
- Use thermoplasitc or thermosetting polymers.
- Vacuum forming
- Steps for vaccum forming
- Step one the high impact polystyrine is heated.
- Step two the selected shape is raised into the plastic.
- Step three the air is then removed from the mould and is then left to set.
- The sheet of plastic is heated to make it flexable the formed over a mould and then left to cool for it to become hard.
- Moulds often made from wood
- Steps for vaccum forming
- CAD
- Computer aided design
- Pro desktop
- CAM
- Computer aided manufacture
- Laser cutter
- Continuous flow
- is a production where mant thousends of i dentical products are made non stop
- Batch production
- Is when a small quantity of identical products are made
- Mass production
- is when hundreds of identical products are made ussually on a production line.
- One-off production
- Is when only one product is made a time
- Soldering
- Soldering is a type of brazing which works at lower tempratures
- Soft soldering
- is used to make permanent joints between copper, brass, tin-plate or light steelwork, and is normally used to join components to electronic circuit boards
- Hard soldering
- is used for stronger joints
- Brazing
- It bonds two pieces of metal by melting a filler metal or alloy between the components
- Welding
- Two pieces of metal are melted along the selected joint which the fuse together as they cool
- Line bending
- Drawing techniques
- 3rd angle orthographic
- 2 point perspective
- 1 point perspective
- Isometric
- Joining wood
- Screws
- Nails
- Knock down joints
- these joints are commonly used in flat-pack furniture, which is assembled by the customer at home
- **** joint
- Box joint
- Coner halfing
- Housing joints
- Working properties
- Hardness
- is the ability of a material to resist wear,scatching and indentation
- Toughness
- is the ability of a material to withstand blows or sudden shockswithout breaking
- Conductivity
- is the ability of a material to conduct heat or electrical energy
- Strength
- is the ability of a material to withstand a forse without breaking of bending
