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. While this statement is technically true, some designs are inherently more challenging than others. A fine example of this is printing a design with a prominent overhang. 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? 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 . In this process, the melted filament material exits the extruder nozzle and is deposited on a surface. AT this point, the filament starts to cool down, solidifying the later while fusing with the layer directly […]
