For this assignment, I chose to work in Rhino\/Grasshopper with the Extruder Turtle library. This involved a lot more geometry than I expected which challenged my spatial reasoning. I went through quite a few iterations of objects I was interested in producing. The first iteration was a crown-like object generated by a cylinder with spikes along the top edge. After a few tries, I decided to go in a different direction. I experimented with different amounts of layers and expression for generating the curves. I was primarily interested in creating circular shapes with lots of motion in the z-axis, especially upwards. I eventually settled on sea-inspired shapes: a shell, sea anemone, and jellyfish. Each of the final forms use the forward_lift command which allows the turtle to move forward and upward at the same time. The anemone and jellyfish also use freeform filament, so they all cannot be generated by a traditional slicer.<\/p>\n\n\n\n

I went through many iterations for each of the forms. The shell required a couple tries due to printer errors. I also experimented with the speed of the extrusion and the temperature of the filament. Then, the sea anemone was the most influenced by the original crown shape, and it required some iteration in order to get the spikes to connect properly. I needed to increase the amount of lines on the top surface of the object and rework the shape of the spikes so that the printer was not crushing them as it printed. The jellyfish was the most frustrating form to print. I went through many iterations adjusting the length of the strings, angle of printing, and height of the cylinder. Similar to the sea anemone, some of the trial and error was due to the printer hardware interfering with the printing. <\/p>\n\n\n\n
