Introduction: Week 7: Clay 3D Printer (Clay Cup)

In this instructable, I will guide you through the process of creating a functional 3D printed clay cup using Grasshopper for GCode generation and the Potter Bot for printing. I will share the steps I took, including the Grasshopper workflow provided in class.

Supplies

  • Computer with Grasshopper installed
  • 3D printer (Potter Bot)
  • Clay suitable for 3D printing
  • Clay extruder
  • Clay cutting tool
  • Water for clay conditioning

Step 1: Designing the Cup in Grasshopper

  1. I opened Grasshopper on my computer and loaded the workflow provided in class.
  2. The workflow already had a cup design component, which I used to generate the cup shape.
  3. I adjusted the parameters, such as height and diameter, to customize the cup's size to my preference.

Step 2: Generating GCode in Grasshopper

  1. With the cup design component in place, I connected it to the Grasshopper component for GCode generation.
  2. I ensured that the printing parameters, such as layer height and print speed, were set according to the specifications of the Potter Bot and the clay being used.
  3. After confirming the GCode preview, I saved the generated GCode file.

Step 3: Preparing the Potter Bot

  1. I prepared the Potter Bot for 3D printing by cleaning and assembling the clay extruder.
  2. Next, I loaded the clay into the extruder, ensuring it was properly conditioned for smooth extrusion during printing.

Step 4: Printing the Cup

  1. I transferred the GCode file to the Potter Bot's control system.
  2. I initiated the printing process and closely monitored the initial layers to ensure proper adhesion and extrusion.
  3. Throughout the printing process, I periodically checked the extrusion to ensure its consistency, making adjustments as needed.
  4. During the printing process, I encountered some challenges with inconsistent extrusion, but I was able to overcome them by modifying the Grasshopper workflow.
  5. Once the printing was complete, I allowed the Potter Bot to finish the entire cup.

Step 5: Post-Printing Finishing

  1. After removing the cup from the printing bed, I inspected it for any imperfections or support remnants.
  2. Using a clay cutting tool, I carefully removed any unwanted parts or support structures if necessary.
  3. Finally, I allowed it to air dry.
