Zusammenfassung:	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). 本发明涉及一种用于3D打印机(1)的打印头(10)，所述打印头包括：进料区(11)，所述进料区具有用于粘度变化的初始材料(21)的供应部(12)；塑化区(14)，所述塑化区具有加热装置(15)和用于所述初始材料(21)的液相(22)的排出开口(16)；以及输送装置(30)，所述输送装置用于将所述初始材料(21)从所述进料区(11)输送到所述塑化区(14)中，其中，所述输送装置(30)包括能导入所述进料区(11)中的活塞(31)。本发明的特征在于，所述活塞(31)具有面向所述塑化
