Additive manufacturing method in which a detail is created layer by layer by melting a plastic wire and applying it through a heated nozzle. Beskrivning The process The product is formed on a mobile building platform [1]. A plastic wire [2] is fed through rollers [3] pushing the thread through a heated nozzle [4] where the wire is heated and then ejected from the nozzle at constant speed to build a cross section of the CAD model. After each layer, the building platform is lowered and the next layer is added. If necessary, a supporting structure is also printed [5] to allow overhangs. Post-processing in the form of removal of these support structures is required. Grinding, waxing or heating of the surfaces may be required if higher surface finish is desired.
