We used two 3D printing technologies, Selective Laser Sintering (SLS) and Fused Deposition Modeling (FDM), and the most commonly used materials PA12 and PLA to print the same hyperbolic planetary gearset. After assembling the parts, we pushed them to their limits on our mechanical bench drill. Which part do you think will win this showdown?
