Basics

The 3DBenchy, often reffered to as simply a "benchy" is a standard test print done for calibration purposes (Both of 3D Printers, and/or for a Material Used in One)
It combines many aspects of 3D Printing Challenges allowing for many potential issues to be spotted in one print
It also has the aesthetic of a Small Toy Tugboat
- This makes them less of a "Print, Look Over, then Throw Away", and more of a "Put on a Shelf" for some, however compared to more minimialistic Calibration Prints it uses more material and Machine Time

One can look for obvious errors like Stringing (FDM 3D Printing Artifact) , Layer Shifts, Underextrusion / Overextrusion , the charachteristic Bubbles/Degradedation from Wet FDM 3D Printing Filament etc
Also as detailed in A Section of The Project's Website , Various Dimentions/Angles can be checked
- Someone who's good at embedding this feel free to do so, would make for a quicker reference!

It is often used as a metric for not just how well a printer can print, but also at what speed it does so
A project around this was created called #SpeedBoatRace (Although "Speed Benchy" and similar terms are also used)
In the more Extreme Examples, something more akin to a "Benchy Like Object" is created due to various artifacts, but nonetheless most Speedbenchies by Fast 3D Printers are below 15 minutes, and some are below 5 minutes!
Really interesting example of Competitions as Technology Accelorators that has lead to some very interesting designs with Novel Cooling Mechanisms
