When it came to creating this vessel I had a lot more ideas when it came to playing around with the basic modeling code that we made in class. I tried to create a vessel that was made up of two squares with a triangle topping it and being lofted upwards. However, my printer and Cura had other plans and instead created one of the worst models in Cura that I had ever seen. <\/p>\n\n\n\n

So I believed that I needed to dumb down the design and make it simple by just lofting three different hexagons forming the model that I have above. Despite making the model more simple I ran into some printing issues with the printer snapping off a piece of the print then making the infamous spaghetti. With the other failure 3\/4 of the way through it decided that it wanted to shift the entire print ruining a good print. Getting my printer and Cura to just make this was horrible and I heard noises coming from the belt and extruder as it would print from time to time. I adjusted the belt numerous times and leveled my bed almost ten times. It wasn’t until I saw a video showing how to tighten the x-axis belt even more by using the large allen wrench as a lever to pull the belt as tight as it should be. After fixing the belt I didn’t have anymore off-centered layers or prints and I had also gotten my bed level to create all my prints. All of my prints came out to 38.1×38.1×63.5 to meet the requirements for this assignment so my models are much more stretched than their original Rhino renderings. I also believe that the twist angle feature in GrassHopper caused a lot of rendering issues with both Rhino and Cura since the majority of my prints had missing pieces that weren’t evident from the Rhino file until I sliced it. <\/p>\n\n\n\n

This design was really fun to make, and I created it by altering the the triangle gear function that we made in class and replaced the two point gear with essentially a three-point one which made the geas created a lot more flat and more like a flower outline. Originally I made this shape very wide and bulbous and because of the the little gear design on the bottom it made it look like little feet and with the round shape it looked like Pear from Finding Nemo.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

It was really cute looking and had a very small opening at the top that was more of a hexagon shape, it was the very first failed print and due to my belt being off and Cura not rendering it properly the design was missing tons of pieces from the model and the first two starter prints that I made started printing way off-center and printing all shifted. Of course after fixing the belt I realized that it wasn’t moving as much as it should have so that was causing it to not properly move across the printing bed and print things in the wrong coordingates. <\/p>\n\n\n\n

This vessel was definitely an interesting one that I did not expect it to come out. I just wanted to do a simple sine wave to the polygons by making a new function to alter the points and having the polygons function use those points. I was expecting all the shapes that were created to be wavy, however that was no the case. I altered the amplitude and frequency that passed through the sine function and instead of wavy points it actually distorted all the polygons making them into other shapes and at one point if I turned the amplitude high enough it created a fish design that I really wanted to make but the edges seeemed to twisted and would have had tons of holes where the design couldn’t loft the shapes together. Overall it was a funky looking design that had a nice little wave to its body from the twist but also the alteration from the sine function. Printing it out I made the changes to its size to make it fit the requirements for the assignemnt so it looks a bit more elongated than the design. Despite all these issues all my prints only took about an hour or two to make, but thats if they made it past the first five layers or they messed up in the final layers. Despite the printing time being low for all my prints I would have rather had longer prints with no printer and Cura model issues. For my designs there are still random holes and artifacts that the model had I’m still not sure if it was Cura that did this or maybe I needed to make a higher quality STL mesh for it to render. Overall this was a great experience making the models and troubleshooting my printer longer than it took to model the vessels and print them. <\/p>\n\n\n\n

Reflection: <\/h2>\n\n\n\n

The parametric design process was very fun and exciting to use and explore. There is so much that you can do with the GrassHopper and Python functions to create intricate and interesting models. It definitely speeds up the process of having to manually create a 3D model and calling all the different functions and transformations within Rhino. It does take some time to set up GrassHopper with the type hints matching and the Python code to output what you actually want, but once you have that set up there are endless possibilites and tons of live models you can create and alter with ease rather than having to stress over making model after model by hand. By using code and and tools to formulate new designs it opens up a grand scheme of designs you can make using computation that otherwise you would have to put tons of time in to create and even replicate. It definitely shows you how we can use technology to increase our creative processes and bring more variety when it comes to modeling and designing. This skillset will definitely be one that I will be using going forward and combining with my computer skills. By 3D printing and programming it allows me to create things that I most likely could not have created simply from my own mind and drawn down on paper, I could but it would take a lot more time than it would if I had a 3D printer, GrassHopper, and Rhino to help me bring it to life. <\/p>\n\n\n\n

Overall, when I was creating my different vessels I didn’t have a true design for any of them in mind. I always tend to make things randomly and then it reminds me of another object or some sort of reference. The first vessel that I tried to make with the triangular top it reminded me of an abstract Youtube Play Button and of course my second experimental vessel that looked like Pearl from Nemo, but in the end I change them slightly due to printing issues or the Cura modeling issues. Had I had a perfect run with my printer and the models I believe I would have created some more unique and fun looking designs they just didn’t seem to work out this time around. I feel like I can really put the printer to use its just that some things don’t end up how you envisioned them. I still enjoyed the process creating the different vessels as well as troubleshooting my printer, but I would have surely not had to have used my time mostly to adjusting and fixing my 3D printer despite it working perfectly fine a few days prior. But it also shows me that not all prints are going to work with your basic setup and you are always going to have to tweak things as you go!<\/p>\n\n\n\n
