摘要： A material melting device (10) for melting a work material, and discharge of the melted work material, is described. The material melting device (10) comprises a cold part (12) and a hot part (30), and a work material duct (22) for supplying said work material. The work material duct (22) extends at least partially through the cold part (12) to a melting chamber (33) arranged in the hot part (30). The hot part (30) comprises a nozzle duct (34) extending from the melting chamber (33) to a nozzle opening (35) such that melted work material can be flowed from the melting chamber (33) and discharged from the nozzle opening (35). The melting chamber (33) has a cross-sectional area which is larger than the cross-sectional area of the work material duct (22).
