what is the extruder in a 3d printer
Fused filament fabrication The 3D printer head or 3D printer extruder is a part in material extrusion-type printing responsible for raw material melting and forming it into a continuous profile. A wide variety of materials are extruded, including thermoplastics such as acrylonitrile butadiene styrene (ABS), polylactic acid (PLA), high-impact polystyrene (HIPS), thermoplastic polyurethane (TPU), aliphatic polyamides (nylon),[1] and recently also PEEK.[2] Paste-like materials such as ceramics and chocolate can be extruded using the fused filament process and a paste extruder.[3]
Fidget spinner As of 2017, the patent status of the various fidget spinners on the market was unclear.[8]
3D printing 1988 : The technology used by most 3D printers to date—especially hobbyist and consumer-oriented models—is fused deposition modeling, a special application of plastic extrusion, developed in 1988 by S. Scott Crump and commercialized by his company Stratasys, which marketed its first FDM machine in 1992.
