| 3D Bucks – Bob Krause |
Classroom 3D printing is expensive and time-consuming. There's always more demand than capacity. It's the slowest step in the innovation cycle. Yet all too often kids choose to print more versions of their designs than necessary rather than waiting to submit a job only once it's been sufficiently refined and a print is necessary in order to test and confirm their working assumptions.
Another common classroom challenge is how to motivate students to move beyond their comfort zones and how to reward them for doing so.
Forget Bitcoin. We’re 3D’ers! So we use 3DBucks to optimize printer demand and motivate students to maximize their progress through each lap of the cycle. 3DBucks are credits that students must spend in order to print something. The cost of each print job is based on the amount of filament it consumes. Available denominations are 1 gram, 5 grams, 10 grams, 25 grams, and the special Dual credit. The cost of a job that uses both extruders on the dual-headed printer is based both on the amount of filament it consumes as well as a Dual credit.
