The Delta 3D Printer project is a 2014-2015 Cal Poly ME senior project sponsored by Dr. Jose Macedo, Professor and Department Chair of the Cal Poly IME Department; Yaskawa America, Inc., industry-leading producer of high-quality electronic drives and motors; and Bell-Everman, Inc., producer of high-precision embedded motion systems. The Delta 3D Printer project was conceived by Dr. Macedo as a collaboration between Cal Poly engineering and Yaskawa America. The majority of delta 3d printers on the market utilize stepper motors to control the print head motion. The 3D printer for this project was designed to use servo motors instead of stepper motors. Servo motors allowed us to increase both the accuracy and speed of the printer while providing a constant feedback loop to the control system. The printer uses a fuse deposition modeling extrusion method and prints with 3mm ABS plastic filament. The printer has a 1.5ft diameter by 1ft height build volume.
