In many cases, they also cannot be avoided. Overhangs can certainly be challenging, but they are not problems that cannot be solved. In any case, these features don’t look good and are structurally weak. In minor cases, the overhanging feature can end up sagging or merely delaminated. The feature does not need to completely collapse to be considered a failure. This is an overhang – a design feature that extends far beyond the layer underneath it, leaving it without any direct support.
However, large features without any support underneath them tend to collapse under their own weight. Small amounts of filament without any direct support are fine, as the filament starts to cool down and solidify the moment it exits the hot end nozzle. AT this point, the filament starts to cool down, solidifying the later while fusing with the layer directly below it at the same time.īased on this series of steps, FDM printing relies on each layer being printed on another layer directly below it. In this process, the melted filament material exits the extruder nozzle and is deposited on a surface. To better understand why an overhang is challenging, we need to go back to the basics of 3D printing using Fused Deposition Modelling (FDM) technology.

What is an overhand, and why is it so challenging? Is it something 3D printing professional should just avoid altogether? What are the best ways to succeed in printing a design with an overhang? What is an overhang? A fine example of this is printing a design with a prominent overhang. While this statement is technically true, some designs are inherently more challenging than others.
One of the often-cited reasons for the popularity of 3D printing is that it’s capable of printing any kind of object and design.
