1. Classroom Rapid Prototyping Chris Connors  Pembroke High School  Make: Online Fabrication - Design and Manufacturing Learning about Rapid Prototyping Open Source Software and Approaches

2. Rapid Prototyping Computer Aided Design (CAD) Computer controlled tools Computer Aided Manufacturing (CAM) Designs are made and tested quickly Designers have control of the manufacturing

3. Learning Rapid Prototyping Fab Labs  Worldwide network of labs MIT SponsoredMIT Sponsored  Boston – South End Technology Center  Providence – AS220 MakerSpaces / HackerSpaces  Worldwide movement  Sprout – Thursday project night  Artisans' Asylum – Class structure

4. Design Process “Your first try will be wrong. Budget and time for it” Aza Raskin Aza Raskin Nothing comes out right the first time It may take several attempts until it comes out right This takes patience

5. Design Process Rapid Prototyping allows Design Spiraling  Cycle through the Engineering Design Process  Loop over and over  Refine the design through multiple iterations

6. Fabrication Tools Vinyl Cutter$ Laser Cutter$$ Makerbot – 3D Printer (additive process) $ CNC Mill$ CNC Lathe$ CNC Router $$ $ Relatively inexpensive $$ More expensive

7. Design Software 2D design  Open Office $0  Gimp (similar to Photoshop) $0  Inkscape (similar to Illustrator) $0

8. Design Software 3D modeling  Sketchup $0  Blender $0  123D $0 Parametric 3D  PTC ProEngineer Windows only, proprietary license  SolidWorks Windows only, proprietary license  OpenSCAD $0

9. Fabrication Services You don't have to own the machines fabrication services are available online  Ponoko.com  Shapeways.com  BigBlueSaw.com  100kGarages.com

10. Student Control of Manufacturing In classroom design In classroom manufacturing Custom design Designs are repeatable

11. Make and Refine a Design Design Manufacture Test Improve Repeat until the design is great

12. Production Run Design Develop one design Improve it Remove flaws Create working prototype Develop a plan for production run

13. Make a Production Run Carry out your Production PlanProduction Plan Use your prototype as a production model  Make 5 copies  Make 20 copies  Make 100 copies  Make 1000 copies What would you do with this many products?

14. Rapid Prototyping and Design Quick to get started Models are precise Models are repeatable Models are adjustable Models are refinable

15. Rapid Prototyping and Design Quick to get started  Make your design  Fabricate it  Test it  Improve it  Design for an audience of one is possible

16. Rapid Prototyping and Design Models are precise  Extremely accurate tools  1/1000 th of an inch  Materials can affect precision

17. Rapid Prototyping and Design Models are repeatable  Use the same design over and over  Make production runs  Do distributed manufacturing  Files are easily shared

18. Rapid Prototyping and Design Models are adjustable  Start with a basic design  Fabricate it  Test, revise, improve  Cycle through the Engineering Design Process  Design/Make until it works/assembles properly

19. Rapid Prototyping and Design Models are refinable  Designs can be developed in low cost material  Produce in more expensive material  Change color, durability, texture  Designs can be customized in production

20. Sharing and Collaboration Important 21 st Century Skills Students live in a world of shared information Sharing does not have to be cheating!

21. Sharing and Open Source Open Source enables sharing Info about designs are available to all Designers can get started quickly Legacy of information Results and designs must be shared

22. Who is using Open Source? Google - Chrome, Android Mozilla - Firefox Arduino microcontrollers Makerbot 3D printers You and your students use Open Source daily

23. Sharing and Documentation Thingiverse.com Share your design files worldwide Youtube for parts and designs MakeProjects.com Step by step directions Social community around making Sponsored by MAKE magazine Instructables.com Instructions for making Sharing through text, photos and video

24. Student Tools for Documentation Word processor Camera phone Video phone Printer Word documents can convert to web pages

25. Online tools Make your own instruction set with students or on your own  Accessible worldwide  Wiki  PBWorks.com
