Modelling & Prototyping

Modelling & Prototyping

1. Sketch modelling

   • Foam or similar material
   • Good for ergonomics
   • Constructing a number of different sizes
     • Help compare
       • Aesthetics
       • Determine which to develop

2. Rapid prototyping using CAD/CAM

   • Stereolithography
     • Most companies don't have this technology
       • Use specialist companies
         • Delivered 3-5 days
           • Saves time and development costs
     • Expensive-£10,000
   • Selective laser sintering (SNS)
   • Advantages
     • Fast entry to marketplace
     • Produces complex designs
     • Reduces development time-saves money
     • Accurate

3. Virtual modelling

   • Tested & evaluated without being manufactured
   • Video games
     • Movies
   • Photo-realistic models
     • Used by architects
