How does Fused Deposition Modeling (FDM) work in 3D printing?

23 Eyl 04:45

I'm trying to grasp the basics of Fused Deposition Modeling, the most common 3D printing process. Could someone break down the principle behind FDM, including how the filament is melted, extruded, and solidifies layer by layer? Also, what are the typical material considerations and common challenges when using FDM? Any diagrams or simple analogies would be appreciated.
