  1. Experimenting withRapid Prototyping and Something Called Custom Intersections Dr. Jim Flowers Technology Education Program Ball State University

  2. Rapid Prototyping Technology can • Help your students make professional-quality products without all those skills • Make a link between digital designs and physical objects • Allow students to make successive changes to designs, and then see the effects of those changes • Produce parts needed for larger assemblies

  3. Ball State’s Rapid Prototyping Lab Technologies Include

  4. 3D Laser Scanning

  5. Laser Cutting & Engraving

  6. CAD/CAM Milling

  7. Computer Numerical Control Turning(NC Lathe)

  8. Fused Deposition Modeling

  9. Color Solid Object Printing

  10. Other Technologies in the RP Lab • Tensile tester • Coordinate measuring machine • Plastics granulator, drier, and filament extruders • Manual fabrication tools • Vacuum formers

  11. But RP technologies can also support student experimentation. • They allow the user to control several variables and perform repeated builds changing only the levels of independent variables. • There is so much we really don’t know, and experimentation can help us find the answers.

  12. For example: Optimizing Laser Settings • Power • Speed • Focal Point • Pulses per inch • Lines per inch

  14. Determining the effect of FDM build orientation on tensile strength (T. Orr)

  15. Hey Jim, can you 3D print onto cloth? (Rene Church) • Kyle Samuels, a student in a graduate course on Inquiries into Rapid Prototyping, at Ball State found out. Samuels, K., & Flowers, J. (In Press). Can your students 3D print onto cloth? Technology and Engineering Teacher.

  32. Advertisement • New undergrad and grad class at Ball State: • Green Prototyping & Upcycling, where students • Design, prototype, and test products to promote environmental sustainability • Upcycle with laser cutters/engravers • Attempt to extrude their own 3D filament from post-consumer resins and 3D print with it • May be used as an elective in our Master of Arts in Technology Education

  33. Assisting others in their research:Kevin Barnes & Kamal Islam • Scanned warbler model • 3D printed 10 decoys • Decoys were painted and added to buckets playing songs to attract cerulean warblers to nest.
