Understanding 3D Printing Technology

At its core, 3D printing, also known as additive manufacturing, involves creating three-dimensional objects from digital files. The process begins with a 3D model, which is sliced into layers by specialized software. Various technologies, such as Fused Deposition Modeling (FDM), Stereolithography (SLA), and Selective Laser Sintering (SLS), allow for different materials—ranging from plastics to metals and even biological substances—to be used in the printing process. Each technology has its strengths and applications, but the fundamental principle remains the same: layers of material are added one on top of the other until the final product is complete. This innovative approach not only enables rapid prototyping but also allows for customization and complex geometries that traditional manufacturing methods struggle to achieve.
