Embodiment Construction

[0029] now refer to Figure 1 to Figure 15 , a device for printing a three-dimensional object from a build material comprising a cosmetic formulation is indicated generally at 2 . The printhead assembly 129 is supported on a base machine 130, such as a MakerBot Replicator2 or similar printer. The base machine has a positioning assembly (shown generally at 27 ) that includes a top frame rail 131 , an x-axis support platform 132 and a carriage rail 134 for supporting and positioning the printhead assembly 129 . Flexible wiring sheath 135 connects printhead assembly 129 to base machine 130 in electrical communication. Printhead assembly 129 includes extruder 4 having piston barrel 105 with inner wall 5 defining cylinder 6 . The cylinder 6 has a first end 7 and a second end 8 . The piston 104 is mounted in the first end 7 of the cylinder 6 such that the piston 104 can be advanced and retracted in the cylinder 6 . The piston 104 has a front wall 9 and a rear wall 10 connected b...

Abstract

A device printing a three dimensional cosmetic article from a build material including a cosmetic formula has an extruder, a build plate, a controller and a positioning system. The controller is programmed to instruct the positioning system to position the extruder relative to the build plate. The extruder includes a piston extrusion system. The build material is provided to the extruder as a pre-formed stick. The build material is extruded onto a substrate to form the article. The build plate includes a sizing system for receiving substrates of various sizes.

Description

technical field [0001] The invention relates to devices for three-dimensional printing. In particular, the present invention relates to a device for printing three-dimensional cosmetic articles by fused deposition from build materials comprising cosmetic formulations. Background technique [0002] Three-dimensional ("3D") printers for additive manufacturing are well known. An example of such a printer is disclosed in Mayer, US Patent No. 8,529,240. The device disclosed by Mayer uses a controller and other hardware, a positioning assembly with stepper motors, an extruder and a build plate to fabricate an article from a 3D computer model via additive deposition of plastic build material. The relatively rigid plastic filament build material is fed by a stepper motor from a spool into an extruder, where it is melted by heaters and extruded through a nozzle. Mayer does not disclose the piston used to advance the build material. [0003] US Patent Application No. 2015 / 0314141 ...
