STEMx 3D printing 9/20/2013

  1. 1. PAST Foundation provides teachers with a process to deliver meaningful STEM education. “Meaningful” differs for every learner and every teacher. The PAST designed toolkit and Knowledge Capture program enables entire communities to transform traditional classrooms and reach every learner. The results are engaged students, empowered teachers, and a community actively involved in student success.
  2. 2. My work at PAST focuses on COMMUNITY VOICE Knowledge Capture: Understanding You PAST ethnographers use a set of methods that identify issues, success, and constraints to help steer policy and drive successful transformation.
  3. 3. Elliot Mork STEM Coordinator and Logician of Learning B.S. Aerospace Engineering Engineer and Educator • FIRST Robotics, FRC and FLL Coach – Judge Advisor for FLL • Fabrication lab • Fabrication high school internship program • Curriculum development and implementation
  4. 4. What is 3D printing? • Adding material layer by layer to build a structure. • Different from subtractive manufacturing (mill, lathe, CNC routing) by adding material instead of taking it away. • Plastic, powder, metal and other polymers. • Classroom models include ABS (think McDonalds toys) and PLA plastic.
  5. 5. Printing with a 3D printer using ABS plastic Subtractive manufacturing using a CNC table router
  6. 6. Industry Applications Why 3D printing will change the world
  7. 7. Rapid Prototyping • Current injection molding requires costly and time consuming mold creation. • 3D printing allows for faster prototyping so a mold is only made once. Photo used with permission, Author Arne Huckelheim Photo in the public domain.
  8. 8. Internal Structure • 3D printing allows for a customized internal structure of parts. • This can be varied to save weight and conserve strength. Photo by Dr. Andrew Bruening
  9. 9. Personal Manufacturing • Individuals can manufacture custom parts in their home. • Examples include cell phone cases, camera mounts, jewelry, and whatever else you can think of! Photo by CodeCreations, Photo by Paul Hoover,
  10. 10. Educational Applications So how is this useful for me?
  11. 11. Application of Knowledge • 3D printing and CNC machines applies geometry, trigonometry, design thinking and more.
  12. 12. • School projects can take a lot of time, supplies and expertise to build. • 3D printing allows for faster design cycle iterations, therefore more modifications. • Students can try ideas out instead of teacher guiding toward “correct” answer and method. • Ideo shopping cart is great example of design work: Rapid Prototyping
  13. 13. Produce Products • Use the 3D printer to produce final products for student projects. Photo by drayde, :3784
  14. 14. Tools and Starting Points Where should I begin?
  15. 15. Machines 3D System’s Cube • $1,299 • ABS or PLA • 166 cubic inch build volume Makerbot’s Replicator 2 • $2,549 • 100 micron resolution • PLA Plastic, upgrade for ABS • 410 cubic inch build volume cator2.html
  16. 16. Build Process Design a thing Translate the thing into printer language Print the thing • Printcraft • TinkerCAD • 123D Sculpt • Any CAD program  .STL file format  Use someone else’s file ( • Makerware • Slic3r  This program usually comes with the 3D printer  Settings like fill ratio and fineness • 3D printer • ABS • PLA • Resin/Powder
  17. 17. • Site for sharing .STL files. • Other people have created many things you can just print!
  18. 18. Printcraft • An online minecraft server that allows you to export .STL files from objects you build while playing a video game.
  19. 19. TinkerCAD • Extremely simple CAD program suitable for younger students. • Drag and drop functionality to create .STL files.
  20. 20. Autodesk • Robust professional tool suitable for high school students. • More challenging to learn but prevalent in education.
