RaneemLarge Assignment 4 - GCODE

GCode- Raneem

Process

For all figures of the process, I wanted to implement the vessels project into this assignment and see how the code changes based on the changes I make to the twist of the object as well as the number of points for extruding the turtle nozzle. All my shapes used were hollow from within and had a twist in the angle. Thereby, the shapes could not be generated by a traditional slicer. Additionally, I purposely made Figures 1 and 2 without being filled in so it shows the extrusion from inside and outside on each layer. I attempted to print the object as a whole at first however it did not go as planned as it over-extruded the filament and curled up everywhere.

I used the previous vessels in Rhino project and made necessary changes to meet the complexity that I was aiming for and how exactly I wanted the extruder to cut through the form and create an opening. The double layers allows me to have that cut within the vessel which I found interesting.

Figure 3 Formation with Non-Planar Movement

I created a vessel model to allow the turtle extrusion to move on a path around the structure. The vessel is created as a support for the movement of the turtle. This also created a spike upward weave form.

Iterative Design

In Figure 3, I had to go back and forth with the printer. I wanted to make sure that the extrusion on the Z-axis did not fall apart. I originally wanted to do a star but it curled up and extruded a shape with no form. I played with different Z-axis using the pitch_up and pitch_down functions and noticed that they needed to be narrow enough on the horizontal plane for the extrusion to build on each other.

After adjusting the extrusion lift, I came to the conclusion that the object needed a narrow lift. I wanted the design to have an almost spherical center to maintain the movement of the nozzle in the Z axis. The form also bounces and, due to its center of gravity, it returns back to the flat, hollow, horizontal surface.

  1. Hello Raneem, I really enjoyed looking at your objects. I really liked the previous vessels and how it came out. The extra part from the objects that was really heavy compared to the rest of the object was really cool. Great Job!

    1. Hi Atah, thank you! It also surprised me how the heavy double layered one could stand on its own.

  2. Hi Raneem,
    Your project is really interesting, The vessels translated are fun too look at with the double layers and the cut in the side makes for cool objects! The little ball you made too is really nice especially including the non planar movements in it! Good work!
