Custom-built Direct Ink Write (DIW) 3D Printer
The student-built direct ink write (DIW) 3D printer designed for testing viscous additive manufacturing materials and studying the effects of process parameters on the additive manufacturability of these materials. The printer is equipped with several pressurized dispensing heads that allow it to print a variety of materials, including two-part (2K) mixtures, ranging in viscosity from 1cP to greater than 150,000 cP. Customizable print parameters include dispensing and slicing strategies, machine feeds and speeds, dispensing pressure, filament/nozzle diameter, and material curing methods. The machine also incorporates print monitoring equipment, including thermal and high-speed cameras. The build volume is 500 x 300 x 100 mm, with a minimum layer height of 0.040 mm.
