Which additive manufacturing method is particularly suited for producing complex geometries?

Fused deposition modeling (FDM) is particularly suited for producing complex geometries due to its layer-by-layer additive process. In FDM, filament is extruded through a heated nozzle, allowing the material to be deposited precisely where it's needed to build up the object. This method enables the creation of intricate designs and features that would be challenging or impossible to achieve using traditional subtractive methods, such as milling or machining, which removes material from a solid block.

Moreover, FDM can easily accommodate complex internal structures, overhangs, and unique shapes thanks to its ability to print support materials that can be removed later, further enhancing design freedom. This capability makes it a popular choice for prototyping and production of complex parts in various industries, such as aerospace, automotive, and healthcare.

Other methods like subtractive machining, injection molding, and stamping are better suited for high-volume production of simpler shapes and require significant tooling or molds, making them less efficient and more expensive for designs with high complexity.
