Abstract: The invention relates to a print head (10) for a 3D printer (1), comprising a feed section (11) having a feeder (12) for a starting material (21) that is variable in the viscosity thereof; a plasticizing zone (14) having a heater (15) and an outlet opening (16) for the liquid phase (22) of the starting material (21); and a conveying device (30) for conveying the starting material (21) from the feed section (11) to the plasticizing zone (14), wherein the conveying device (30) comprises a piston (31) that can be inserted into the feed section (11). The invention is characterized in that the piston (31) has a first piston portion (5) facing the plasticizing zone (14) and having a guide surface (9), through which the piston (31) is guided in a bore (7) of the print head (10).

Abstract: The invention relates to a method (100) for establishing a connection between an inlay (1, 1?, 1?) and a polymer (3) at least partially surrounding the inlay, wherein a monomer (2) is brought into contact (110) with the inlay (1, 1?, 1?) and is subsequently polymerized (120) to form the polymer (3), wherein the temperature TE of the inlay (1, 1?, 1?) is increased (130) at least briefly at least to that temperature TM that the monomer (2) assumes at its maximum during its exothermic polymerization (120) to form the polymer (3), and/or that ensures that the heat flow always runs from the inlay (1, 1?, 1?) to the monomer (2). The invention also relates to a method (200), (300), (400) for the sealing integration of an inlay (1, 1?, 1?) in a component (5).

Abstract: The invention relates to a print head (10) for a 3D printer (1), comprising a feed zone (11) with a feed (12) for feedstock (20) with variable viscosity, a melting zone (14) comprising a heating element (15) and an outlet opening (16) for the liquid phase (22) of said feedstock (20), as well as a conveyor device (30) for conveying the feedstock (20) from the feed zone (11) into the melting zone (14), said conveyor device (30) comprising a plunger (31) that can be inserted into said feed zone (11).

Abstract: Printhead (10) for a 3D printer, comprising an operational volume (17) for holding feedstock (20), the viscosity of which can change, the operational volume (17) being variable by moving a plunger (31, 31a, 31b) and being provided with an outlet (16) through which the feedstock (20) can be extruded by moving the plunger (31, 31a, 31b), the plunger (31, 31a, 31b) being equipped with temperature control means (36).
