What is the primary function of FDM?

The primary function of Fused Deposition Modelling (FDM) is to form 3D objects from Computer-Aided Design (CAD) generated models. This additive manufacturing process involves the layer-by-layer deposition of thermoplastic material, which is heated and extruded through a nozzle to create the desired shape.

FDM is a popular method in 3D printing because it allows for the production of complex geometries that are often difficult or impossible to achieve with traditional manufacturing techniques. By using a CAD model, designers can specify intricate details and dimensions, which FDM then accurately reproduces in physical form. This capability makes FDM particularly valuable in various fields, including prototyping, manufacturing, and even education, where rapid iteration and the ability to visualize designs are crucial.

Other options do not align with the fundamental purpose of FDM. For instance, creating two-dimensional designs from sketches is not a function associated with FDM, which focuses entirely on three-dimensional output. Likewise, while material strength can be a consideration in FDM due to the layering approach, it is not the primary function of the technology. Lastly, printing designs on paper is unrelated to the FDM process, which is dedicated to fabricating three-dimensional objects rather than producing print media
