  2. 2. Rapid Prototyping Facilities3 different kinds of machines:1. A machine producing models in plaster (not for functional tests). This process is called ‘3D Printing’ or 3DP.2. A machine producing models from fluid acrylic type of plastics. The process is SLA-like, make very small details in thin layers to 25 microns but is rather slow.3. 2 machines producing models from a plastic thread. They are made from self-assembly kits and are very cheap. The process is called FDM (Fused Deposition Modeling) and is rather fast compared to the aforementioned processes.2 Original material by Thomas J. Howard for course 42629 – Innovation and Product Development 2012 Department of Mechanical Engineering, The Technical University of Denmark
  3. 3. Manufacture and Fabrication Facilities1. Produce and engineering drawings and 3d sketches of the parts2. Print them out on paper and go to discuss with Jan Frank Pedersen at the earliest opportunity.3. Provide Jan with the files/drawings he requests and arrange with him a schedule of work and your deadline.3 Original material by Thomas J. Howard for course 42629 – Innovation and Product Development 2012 Department of Mechanical Engineering, The Technical University of Denmark
  4. 4. 4 Original material by Thomas J. Howard for course 42629 – Innovation and Product Development 2012 Department of Mechanical Engineering, The Technical University of Denmark
  5. 5. Paper prototyping5 Original material by Thomas J. Howard for course 42629 – Innovation and Product Development 2012 Department of Mechanical Engineering, The Technical University of Denmark
  6. 6. Proof of principle prototypes Oversights revealed by the Prototypes Concept 1 Concept 2 Concept 3 – Awkward assembly – Awkward assembly – Lock insecurity revealed – Very small increments – Cannot work in all – More flimsy than for code orientations anticipated – Code revealed under – To release bars must – Supporting pin are too tube first be raised small – More flimsy – Awkward to adjust code – Awkward to adjust code – Lock insecurity – Lock insecurity + Simplicity realised revealed revealed + More discreet than + More sturdy + Dimensionally suited anticipated + An effective visual + Locks securely even deterrent when code is <2mm out6 Original material by Thomas J. Howard for course 42629 – Innovation and Product Development 2012 Department of Mechanical Engineering, The Technical University of Denmark
  7. 7. Prototype vs Production Model Prototype parts Extruded parts Instead of using a T cutter to form the extra lip T cutter would have been required Mill Square then fasten will screws. for this section7 Original material by Thomas J. Howard for course 42629 – Innovation and Product Development 2012 Department of Mechanical Engineering, The Technical University of Denmark
  8. 8. Proof of principle/form prototype8 Original material by Thomas J. Howard for course 42629 – Innovation and Product Development 2012 Department of Mechanical Engineering, The Technical University of Denmark
  9. 9. Mk. 99 Original material by Thomas J. Howard for course 42629 – Innovation and Product Development 2012 Department of Mechanical Engineering, The Technical University of Denmark

  12. 12. Prototype for assembly12 Original material by Thomas J. Howard for course 42629 – Innovation and Product Development 2012 Department of Mechanical Engineering, The Technical University of Denmark
  13. 13. Sun cream on demand What would a prototype be able to tell us about the product (excluding the market) ?13 Original material by Thomas J. Howard for course 42629 – Innovation and Product Development 2012 Department of Mechanical Engineering, The Technical University of Denmark
  14. 14. Protovate your product Taking your own project and your list of burning questions, design at least 1 prototype and test for the product’s function or the production feasibility. 10mins14 Original material by Thomas J. Howard for course 42629 – Innovation and Product Development 2012 Department of Mechanical Engineering, The Technical University of Denmark
  15. 15. Questions ?15 Original material by Thomas J. Howard for course 42629 – Innovation and Product Development 2012 Department of Mechanical Engineering, The Technical University of Denmark
