Printing overhang geometries

Overhang areas are sloped faces that protrude beyond the base of our model. We actually already faced a similar concept, undercuts, when studying milling issues:

Figure 15.1: Undercuts for milling

As we may recall, undercuts are geometries that cannot be reached by the cutting tool, they are a huge limitation to milling processes even if we already found several possible solutions to fix undercuts in Chapter 7.

In this section, we will focus on additive manufacturing to find out whether undercuts are an issue that affects FDM printing as well, and if so, how.

Facing overhangs (undercuts) in 3D printing

Before jumping to the answer, let’s get back to basics – additive manufacturing, instead of removing material from a solid block, creates a shape by stacking multiple layers one on top of the other.

Fabrizio Cimò

Fabrizio Cimò is an Italian engineer who has always had a passion for the world of 3D graphics and design. During his first degree in industrial design, he started uploading video lessons covering 3D modeling tools such as Rhinoceros, Blender, and Fusion 360 on his YouTube channel. Sometime later, Autodesk noticed his work and asked him to keep promoting Fusion 360 as an official student ambassador. During this time, he also joined Dynamis PRC, a racing team from Milano PT competing in the Formula SAE championship; thanks to this experience and his avid curiosity, he improved his knowledge of the manufacturing world. Today, Fabrizio works as a machine designer for an important company in the laser-cutting sector.
