The 3D model is designed to print at 1:1 scale without support materials. It is challenging for most 3D printers but the small volume (15.55 cm3) typically prints in well under two hours and does not require much material.
The different surfaces of the #3DBenchy model reveal typical issues regarding surface finish, model accuracy, warping, etc.

The shape and size of this 3D model is designed to challenge 3D printers. Compare your #3DBenchy results with the dimensions illustrated in this link. These are easy to measure with a caliper.
Print and check your 3D-printer’s result for dimensional accuracy, tolerances, warping and deviations related to changes in printing parameters and material types.
