3d Printing using Mine Tailings

Current mining processes produce millions of tons of mine tailings each year. Mine tailings are byproducts that can cause several environmental issues and community hazards. The team designed a 3D printer that can print concrete structures using mine tailings. The 3D printer operates by taking commands in the G-code programming language based on the design of the model being printed. The printer is equipped with ethernet connectivity, augmenting its functionality and accessibility.

Duet Web Control is an online user interface that provides operators with an intuitive and user-friendly way to control the 3D printer. Duet3D, an advanced high-power controller, is used to synchronize and configure the movements of the 3D printer’s five stepper motors. The 3D printer features three axes (X, Y, and Z), with a single motor to control the Y axis, two motors for the X axis, and two motors for the Z axis. The Y and Z axes use ball screws for linear motion, whereas the X axis uses racks and pinions. Each axis is capable of 4 feet of travel, which can yield a printed structure of 4 feet by 4 feet by 4 feet.
