1. Manufacturing Systems

   • One off
     • When a product is made specifically for an event or a customer. The product will be expensive
       • Wedding cake/dress
       • Prototype
   • Batch
     • When a product is produced depending on its demand. Manufacturing is normally divided into a number of separate stages during batch production. Each stage is carried out using different machines.
       • A batch of 100 cars made when the stock runs out
   • High volume
     • when large numbers of identical products are produced on a production line. Its expensive to setup and requires a lot of the produced products to be sold for it to be profitable
       • Nuts and bolts

2. Legislation

   • Trade Description
     • It makes trading a product or service with false or misleading statements an offence

3. Impact of design & manufacturing on the environment

   • Sustainability
     • Sustainable products are those products that provide environmental, social and economic benefits while protecting health and environment over their whole life cycle, from the extraction of raw materials until the final disposal.
   • Carbon footprint
     • The amount of carbon dioxide released into the atmosphere as a result of the lifecycle of a product
   • Lifecycle
     • Lifecycle is the stages a product goes through from its design at first to its disposal.
   • Recycling
     • Recycling is the process of converting waste materials into new materials and objects. It is an alternative to "conventional" waste disposal that can save material and help lower greenhouse gas emissions

4. Smart & modern materials

   • Smart materials are designed materials that have one or more properties that can be significantly changed in a controlled fashion by external stimuli, such as stress, temperature, moisture, pH, electric or magnetic fields.
     • Shape-memory alloys
     • Electroluminescent materials
     • Colour-change materials
