The world of FFF (Fused Filament Fabrication) or FDM (Fused Deposition Modeling) printing, is a type of 3D printing that allows us to create physical objects from a digital design file. Imagine a continuous filament of thermoplastic material, similar to a strand of spaghetti. Now imagine a small nozzle, heated to a precise temperature, that can extrude this material with incredible precision. As the nozzle moves over the build platform, it deposits the material layer by layer, building up the object according to the digital design file. As each layer cools and solidifies, it adheres to the previous layer, creating a three-dimensional object right before our eyes. FFF/FDM printing is a remarkable process that allows us to bring our digital creations to life in the physical world. This technology is widely used for prototyping, manufacturing, and educational purposes, and it is known for its relatively low cost and ease of use. Thanks to the widespread availability of materials, the possibilities are almost endless with FFF/FDM printing. We can create almost anything our minds can imagine.
