Abstract

Design of a Recycling System for the Cupcake 3D CNC Printer AbstractThis paper presents the design and development of a recycling system for the Cupcake 3D CNCprinter, a special class of machines designed for the automated construction of physical objectsusing additive layer manufacturing technology. The Cupcake 3D printer system is great forfabricating parts and designs that are not available on the open market. However, as with anyprototyping system waste product is produced regularly when designs are improved or discarded. In alearning engineering lab environment waste is even more likely to occur. The cost of the printerfilament and impact on the environment will increase as petroleum and other manufacturing costsincrease.The Cupcake 3D printer is used to quickly fabricate plastic parts for projects but generates waste thatcannot currently be reused by the printer. The existing system for the Cupcake printer lays down agrid of material as a base before it starts fabricating parts from the design files. The base aids instability while the printing process is occurring. After the parts are complete they are cut from thebase, and the base is discarded along with any misprints and support materials. The excess waste is aproblem for several reasons. The Cupcake prints with Acrylonitrile Butadiene Styrene (ABS), High-Density Polyethylene (HDPE) and Polylactic Acid (PLA) plastics which all degrade very slowly inlandfills.To print a design, the 3D CNC printer platform will moves in the X-Y plane and the extruderalong the Z-axis with precision stepper motors while the extruder continually places a smallstream of melted ABS. The recycler’s addition to the printing system provides a way to reducecost and make the system more environmentally friendly. Use of a screw type extruder for therecycling system for the rapid prototyping machine which receives the castoff ABS as well asABS bought in pellet form. A gravity fed hopper was used to feed particulate ABS into the screwgrooves. A rotating auger bit inside an enclosure barrel forces the particulate down the tube. Anelectric motor was used to turn the auger which grabs the material to move it down the barrel.Prototype of this design as well as the Cupcake 3D printer was fabricated and tested to determineproper functionality. Parts printed using the 3D printer, the advantages of the recycling system,the difficulties encountered during the design and development of the recycling system, andrecommendations for future recycling system design are presented and discussed.
