What causes Benchy Hull line?

We believe that the main culprit is the sudden transition from sparse infill into full top layers around the 8 mm height (may vary a bit depending on your layer height and number of top layers). At this point, there is an abrupt difference in the time a layer takes to print.

Why is Benchy hard to print?

The boat has lots of little features that can be hard to print: arch ways, cylinders, overhangs, smooth surfaces, tiny details, and horizontal holes. The tiny tugboat's small size also means you can print one fairly quick and it doesn't use a lot of material. Benchy takes about 13g of filament on my set up.

Is Benchy supposed to print without supports?

Features. #3DBenchy is designed to offer a large array of challenging geometrical features for 3D printers, and touch on different issues related to additive manufacturing. The 3D model is designed to print at 1:1 scale without support materials.

Does 3DBenchy need supports?

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.
