Can you print overhangs without support?
The general rule of thumb is: if an overhang tilts at an angle less than 45 degrees from the vertical, then you may be able to print that overhang without using 3D printing support structures. It turns out that 3D printers use a very small horizontal offset (barely noticeable) between consecutive layers.
What happens when you 3D print without supports?
You can 3D print without supports, eliminate additional structures, save filament and your time. And your result will look fantastic and professional even if a 3D print is crafted at home, on an affordable FDM, SLA and other types of 3D printers.
What does an overhang mean in 3D printing?
Overhangs are the bane of engineers and designers who work in 3D printing. A 3D printing overhang is any part of a print that extends outward, beyond the previous layer, without any direct support.
Can you print overhangs, bridges and exceeding the 45° rule?
Note: In order to print more complex objects, you will likely need to have to deal with overhangs, bridges and angles in excess of 45°. Getting that crisp, clean, 3D printing overhang or some sharp ABS bridges can be a bit of a dark art. Essentially 3D printing without support material.
How is support material printed for an overhang?
A break away support material is printed underneath the area where the overhang will be, just like a soluble material. However, unlike a soluble material, once printing has finished and the object has cooled, the breakaway material simply and cleanly snaps off the object, leaving the difficult overhang intact.

How do you make an overhang at a 45° angle?
Basically, in order to create an overhang at any angle less than vertical, your printer offsets each successive layer. The lower the angle gets to horizontal, or 90°, the more each successive layer is offset. So, for example, with a 45° angle, each successive layer is offset by 50%.
