Extreme Overhang Test 75° / Overhang torture test

This overhang test was developed following extensive research and leveraging the expertise shared by Rudolf from Prusa Research.

It is a fixed test at 75°. The rationale for excluding other angles is that any printer with adequate layer cooling should successfully manage all angles from 0° to 75°.

For overhangs exceeding 75°, I recommend using supports (although some printers may handle them without support).

The principle is that the longer an overhang at this angle, the more challenging it becomes to achieve a flawless print. Therefore, it is crucial to AVOID SCALING THE MODEL.

I have meticulously optimized the design to minimize material consumption.

Crucially, DO NOT ALTER THE PART'S ORIENTATION and PRINT WITHOUT SUPPORTS

RECOMMENDED SETTINGS

• Layer height: 0.2 mm
• Speeds: The fastest your machine allows 😜
• Infill: Any infill type suffices. 15% grid infill is adequate.
• 2 perimeters
• Approximate material use: 54 g

This overhang test has been created after extensive research and thanks to the expertise shared by @rudolf.

It is a fixed test at 75°. The reason for not including other angles in this test is that any printer with decent layer cooling should handle all angles from 0 to 75° without issues.

For overhangs above 75°, I recommend using supports (although some machines might be able to handle them).

The idea is that the longer an overhang at this angle, the harder it is to achieve a clean result. That’s why it’s important NOT TO SCALE THE MODEL.

I’ve optimized it as much as possible to minimize material usage.

RECOMMENDED SETTINGS

• Layer height: 0.2 mm
• Speeds: The maximum your machine can handle 😜
• Infill: Any type works. A 15% grid infill is enough.
• 2 perimeters
• Approximate material usage: 54 g
