SpeedBoatRace

Basics

• The #SpeedBoatRace Challenge is a Challenge to Print a 3DBenchy as fast as possible (albeit with some mandatory settings/paramaters if doing the challenge properly )

Rules

Current Official

• You must use PLA, PLA+, PETG, ASA, ABS, or ABS+ (not filled, metallic, or silk filaments as these filaments typically hide defects).
• The maximum nozzle or line width size is 0.5 mm.
• The maximum layer height is 0.25 mm (you may combine infill every other layer).
• You must use 3 top and bottom layers.
• You must use 2 walls and 10% infill.
• The finished print must be dimensionally accurate (within reason) – bonus points if it looks good!
• The machine must be powered by stepper motors.
• You must record the whole print, and the print must finish. There must be a timer or clock shown in the video to verify it’s done in real-time. A phone is fine, or you can show the time before and after the print.
• You must post the video to YouTube, tagged with #SpeedBoatRace.
• You must share the print profile.

Potential Improvements

• No ban on Servo Motors (Maybe in a seperate "No Rules" Build Category)
• Seperate Category for Each Type of Filament (A SpeedBenchy in TPU or Polycarbonate would be impressive!)
• Seperate Categories for Bedslingers , Delta FDM 3D Printers , and CoreXY FDM 3D Printers
• More Quantitative Aspects to Scoring
  • Esentially how to determine what is a "proper benchy" and what is a "benchy like object"
    • Photograhps, or even Photogrammetry and other methods of 3D Scanning would be used, and presense of print artefacts, and to what degree they are present would be scored and calculated
  • Could also do Compressive Strength etc, although the Benchy isn't well suited to this, perhaps print Test Coupons with the same setup?
