The main inspiration for my vessel family was the triangular gears we designed in class. I wanted to use a similar shape, but with square gears rather than triangles. My motivation for the square gears is that it would allow me to have many different parameters that I could modify to get a good variety in my objects. This was relatively simple to implement using the radial function we went over in class with a few of my own modifications to get the square\/rectangular teeth. I also added the ability to twist the layers as I thought this would add a little more excitement to my models. The parameters I used to create the vessels were, for each of the three layers: inner radius, outer radius, number of teeth, tooth size, height, and twist angle. Many of the parameter values that I ended up choosing were geared towards limiting the need for supports to speed up print times and meet the size requirements for the project. Below are the rendered rhino models of the final forms I chose:<\/p>\n\n\n\n

I had no issues printing and all three vessels printed perfectly on the first try. Images of the printing process:<\/p>\n\n\n\n

I really enjoyed designing these vessels. Using python to manipulate the 3d models is so much more intuitive and easier for me than using rhino directly. It allows me to be more exact with my measurements, I can define exactly which functions I want to run where, and I don’t have to deal with any sort of issues that come from trying to click and drag objects and having them end up with behavior I didn’t intend and don’t know how to revert. Particularly for this project, where parameters had to be defined and modified, it allowed me to create and design these three vessels much faster and easier than I ever could have done with rhino alone. Also, being able to define shapes via math functions simplified the process even more.<\/p>\n\n\n\n

As I stated earlier the post, I went into the design process with a very clear goal in mind to create the vessels using circular curves with square gears. I started by designing the most simple version of this shape, which is the first print of my final models. I used this as a sort of base for the other two prints, which I created by playing around with the parameters I set until I found a design that both looked cool and would be easy to print. I wanted one simple base shape, a shape with just a few basic parameters changed from the first, and one with large parameter differences that showed how much of an effect the parameter changes could have. There were quite a few scrapped designs that I really liked the look of, but would require way too many supports that would not only take too long to print, but would also lower the overall visual quality due to the leftover markings that come from removing the supports. These designs implemented the curve twists to a much greater extent than the final models I made, meaning the gears would have an angle that required support on both the inside and outside of the model. As for differences in how I felt about this design process compared to the traditional, I really felt as if I had much more control over the models. I often find when using any 3d software that I click and drag and things happen that I don’t really understand or necessarily want. When designing these I knew exactly what was happening to them and was able to make sure when changing parameters that they reacted in the way I was expecting.
