Printhead for a 3d printer with a pressure measuring system

Abstract

The invention relates to a printhead (1) for a 3D printer (50) for producing an object (6), said printhead comprising a reservoir (2) for holding a liquid phase (32) of a starting material (3) of variable viscosity, means (4) being provided for varying the pressure in the reservoir (2) and the reservoir (2) having at least one outlet opening (5) from which the liquid phase (32) of the starting material (3) can be expelled by increasing the pressure in the reservoir (2) in order to produce the object (6), a pressure measuring system (100) for measuring the pressure of the liquid phase (32) being located in the region (5a) of the outlet opening (5), and the pressure measuring system (100) comprising an adapter device (110), a connecting element (120), a pressure sensor (130), and a liquid medium (140) for transmitting pressure within the pressure measuring system (100). The invention also relates to a 3D printer (50) comprising a printhead (1).
