Object StatementUser assembled 3D printer, 'Cupcake CNC', and accessories, wood / metal / circuitry / wiring, designed by MakerBot Industries, New York, United States of America, 2009, made and owned by Gavin Smith, Sydney, New South Wales, Australia, 2009, used by Gavin and Robots and Dinosaurs, Sydney, New South Wales, Australia, 2009-2012
Physical DescriptionThe printer is comprising a plywood frame that slots together and is held in place by screws. The power supply is located on the right hand side and the majority of the circuitry is affixed to the back. All circuit boards have been assembled and wired together by the donor. There is a metal print bed, on which the 3D print is formed and a heated extruder above through which plastic filament is pushed and melted. The extruder is housed in a plastic frame attached to four runners. The print bed can move from side to side and the extruder is moved up and down. There are a number of computer controlled pulley systems that control the movement of these parts. A number of levels can be seen internally as ensuring the extruder and build platform are flat increases the success rate of a print. At many locations across the printer are marks indicating directions for ease of assembly. On the circuit board a number of handwritten marks have been made to assist in replacing wiring when these need to be moved. The serial number has been handwritten on the replaced back panel after the original panel was damaged.
This 3D printer uses the fused filament fabrication process.
The 3D printer lays down melted plastic onto its build platform layer by layer to construct a 3D object. The shape of the object is determined by a design created in a CAD program, which is then converted in 'slicer' software into a format understood by the machine.
Included with the printer is an automated build platform, released with the second generation 3D printer from MakerBot (Thing-o-matic). The accompanying 3D printed shapes show clear print layers and include examples of printing rafts and issues with printer head alignment. A spare printer head has been included which comprises the stepper motor and cooling fan attached to a metal and plastic frame which is used to attach the heated print nozzle to the printing platform. The nozzle is wrapped in insulation and Kapton tape and all necessary wiring is attached.
