While planning an FDM 3D printing project, engineers have the option to choose from a wide range of thermoplastic materials. They fed the thermoplastic filament into the 3D printing machines in the shape of plastic threads through a nozzle. They melt the filament by heating the nozzle. The heated nozzle deposits the melted filament layer by layer over the build platform. The thermoplastic cools and solidifies gradually as the nozzle moves across the base. Also, they form a solid bond with the earlier layer. https://www.aurum3d.com/FDM-3d-printing-service/
