Experimenting with Rapid Prototyping Dr. Jim Flowers Technology Education Program Ball State University and Something Called Custom Intersections
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
Ball State’s Rapid Prototyping Lab Technologies Include
Other Technologies in the RP Lab Tensile tester Coordinate measuring machine Plastics granulator, drier, and filament extruders Manual fabrication tools Vacuum formers
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.
For example: Optimizing Laser Settings Power Speed Focal Point Pulses per inch Lines per inch
An Experimental Approach to… Everything Orr, T., & Flowers, J. (2014). An experimental approach to… everything! Technology & Engineering Teacher, 73(8), 8-12.
Determining the effect of FDM build orientation on tensile strength (T. Orr)
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.
Successful build test at material’s surface Failed attempt on 100% cotton with a simple weave Post wash test Denim adhesion strength test
Can you make 3D printer filament? Orr, T., & Flowers, J. (In Press). Learning through plastic filament extrusion. Technology and Engineering Teacher.
