Abstract

An extrusion printer including a print head module is described. The print head module is arranged for cooperating with at least one further print head module in a stackable arrangement to form an extrusion print head. The print head module includes a casing having a first outlet channel defining a first nozzle for printing a first material, and a first inlet for receiving the first material from a first supply line including a first material supply. The casing defines a first pump chamber connected to the first outlet channel and the first inlet. The module further includes a first gear pump having two meshing gears arranged within the first pump chamber. A first meshing gear of the two meshing gears of the first pump is arranged for being actuated by a first actuator axle that extends through the stackable arrangement.
