Print head unit (2) for a 3D printer (1) for producing a three-dimensional object (6), comprising: at least one first droplet generator (21), designed to divide up a first melt (72) of a first starting material (71) into individual droplets (73) of a first type, wherein said droplets (73) of the first type can be permanently combined to give the object (6) by adding them in the liquid state of matter in the locations defining the shape of the object (6) and subsequent solidification; and at least one second droplet generator (22, 222, 322, 422, 522), designed to divide up a second melt (82, 282, 382, 482, 582) of a second starting material (81, 281, 381, 481, 581) into individual droplets (83, 283, 383, 483, 583) of a second type, the second droplet generator (22, 222, 322, 422, 522) being controllable independently of the first droplet generator (21). 3D printer (1) for producing a three-dimensional object (6) from a first starting material (71) and a second starting material (81, 281, 381, 481, 581), the 3D printer (1) comprising at least one print head unit (2) according to any one of claims 1 to 6, at least one positioning unit (3) for producing a relative movement between the print head unit (2) and the object (6), and at least one control unit (5) controlling the print head unit (2) and/or the positioning unit (3). Corresponding operating method. |
