Additive manufacturing method in which melted plastic granules are deposited on a bed layer by layer to bild the product. Beskrivning The process The product is formed on a movable platform construction . Plastic Granules supplied to a vertical screw extruder melts the granules down to a molten homogeneous plastic mass. The mass is pressed through an interchangeable nozzle  where the flow is controlled by the diameter and shape of the nozzle orifice. Larger throughput results in higher construction speed but lower surface roughness and vice versa. The mass deposited through the nozzle at constant speed and a cross section of a CAD model is built up. After each layer the building platform is lowered  and the next layer is added. If necessary a supportive structure is printed  to enable overhangs. Finishing in the form of removal of these support structures are required. Sanding, painting or working surfaces may be required if higher surface finish is desired.
