Device and apparatus for selective deposition of molten plastic material and method of manufacture by selective deposition. The device and the apparatus include a melting chamber communicated with a portion of a sonotrode of an ultrasonic transducer, a passage for feeding plastic material, and at least one outlet opening for supplying molten plastic material dropwise or continuously. A feeding of plastic material to the melting chamber is provided. The method includes feeding plastic material to the melting chamber configured in a device for selective deposition installed in a head of a piece of industrial manufacturing equipment, which is moved according to a strategy of its path defined by numerical control on a deposition area, and pouring plastic material melted by ultrasound through the outlet opening.
