Delta 3D Printers
Like many other manufacturing methods there are subsets of 3D printing methods that work a differently to achieve different goals. The most common 3D printing method and the one you might picture when you hear "3D printing" utilizes FDM, or FFF, technology, which stands for "Fused Deposition Modeling" or "Fused Filament Fabrication" (these are two names that describe the exact same thing). FDM 3D printers work by taking a single, long strand of plastic called "filament" and with the use of stepper motors and a motherboard within the 3D printer, softening the plastic to a point where it can be reliably extruded out of a heated nozzle and laid down in precisely dictated toolpaths. Material sciences for plastics are well established and refined which makes this a reliable process to work with and keeps material costs low. You can vary the strength, rigidity, heat resistance, or UV resistance of your finished 3D print by choosing a material that has been designed to maximize the desired properties, offering much more freedom for your finished 3D print's use case than any other 3D printing method.
