Circular economy in additive manufacturing: A study on the feasibility of building a 3d printer from repurposed electronic waste

Abstract

In order to provide creative, cost-effective, and environmentally friendly 3D printing solutions, this study investigated the viability of building a 3D printer using salvaged electrical waste parts. The project required adapting and integrating abandoned electronic parts, including power supply, microcontrollers, and motion control systems. The control system used the Arduino Mega 2560 and Ramps 1.4 board, and the printer was programmed using Marlin firmware. A 20x20 aluminum v-slot profile was used to construct the mechanical framework. Testing of the printer's X and Y axes was conducted to evaluate the performance of the salvaged components. Upon completion of the testing procedure, the X and Y axes exhibited smooth, precise, and controlled movement, with functional endstops effectively preventing over-travel. This demonstrated that the project was feasible, as the successful operation of these axes substantiated the idea that constructing a 3D printer from repurposed parts is viable. This study adds to the increasing body of information on sustainable 3D printing methods and circular economy principles. The findings of this study have significance for the broader area of managing electronic waste, showing the possibilities for upcycling electronic waste and minimizing the harm e-waste causes to the environment.
