A device for printing a three dimensional cosmetic article from a build material comprising a cosmetic formula, the device comprising: an extruder including: a barrel having an inner wall defining a cylinder, the cylinder having a first end and a second end; a piston mounted in the first end of the cylinder such that the piston is able to advance and retract in the cylinder, the piston having a front wall and a rear wall connected by an outwardly directed sidewall, the sidewall shaped and dimensioned to fit closely in the cylinder, the front wall of the piston directed toward the second end of the cylinder; an extrusion nozzle secured to the second end of the cylinder; a reservoir for receiving a quantity of the build material in the form of a pre-formed stick, the reservoir defined by a portion of the cylinder between the front wall of the piston and the nozzle, the piston adapted to apply pressure to the build material to extrude the build material through the nozzle when the piston is advanced in the cylinder and to apply suction to the build material to withdraw the build material into the nozzle when the piston is retracted in the cylinder; and a motor connected to the piston to advance and retract the piston; a build plate located below the nozzle; a substrate for supporting the cosmetic article, the substrate removably secured on the build plate between the build plate and the nozzle to receive the build material from the nozzle; a positioning assembly that positions the nozzle relative to the build plate; and a controller coupled in a communicating relationship with the extruder and the positioning assembly, the controller programmed to position the nozzle relative to the build plate and to advance or retract the build material, such that build material is selectively advanced through the nozzle to be deposited onto the substrate to fabricate the cosmetic article in a three dimensional shape, characterised in that: the nozzle further comprises a hemispherical chamber for receiving build material, in the form of a pre-formed stick with one end in a hemispherical shape, from the reservoir prior to extrusion, wherein the hemispherical chamber is a melting chamber. an extruder including: a barrel having an inner wall defining a cylinder, the cylinder having a first end and a second end;
