Additive manufacturing, commonly known as 3D printing, is a process of creating three-dimensional objects by adding material layer by layer based on a digital design. Unlike traditional subtractive manufacturing, which removes material from a solid block, additive manufacturing builds objects from the ground up.

Processes and Materials : Additive manufacturing uses various technologies, including fused deposition modeling (FDM), stereolithography (SLA), and selective laser sintering (SLS). Materials can include plastics, metals, ceramics, and composite powders, chosen based on the desired properties of the final object.

Applications : This method is used in prototyping, tooling, and producing complex or customized parts in industries such as aerospace, automotive, medical, and research. It allows for rapid iteration of designs and the creation of geometries that are difficult to achieve with conventional methods.

Considerations : Factors such as material compatibility, print resolution, structural integrity, and post-processing requirements influence the effectiveness of additive manufacturing. Safety measures are necessary when handling powders, resins, or high-temperature equipment.

Conclusion : Additive manufacturing enables precise and flexible production of components directly from digital designs. Its use emphasizes efficiency, customization, and complexity management rather than mass production or commercial presentation.
