OBDF 210

 3D Print Tests     After creating 3 different prototypes in Rhino, two to test planned failures and one to test contour "drawing," I finalized one of the designs and proceeded to print it.   I decided on the cantilever design, due to time constraints I believed it would make for the most interesting visual "failure." slow mo.MOV test print.MOV Next Steps The cantilever test worked as I had hoped, so I will be proceeding with this design. The next step will be to create a more aesthetic "base" for the cantilevers, and then proceed to print. I'm still awaiting confirmation on if I can use all 5 printers at once, but if not then multiple prints on the same printer should still convey the desired message.  

3D Printing Design Concepts       This project proved difficult to decide on concepts for because I have no attachment or familiarity with 3D printing. Once we had a demonstration, I recalled one of the artists from my inspiration presentation, Elvira Dayel, describing 3D printing as a medium similar to drawing. Through the demo I could really connect with her describing it that way. Coupled with our discussion in class, I'm going forward with this project considering the process of 3D printing to be the focus of this piece rather than the resulting printed object.     After our 3D printing demo and discussion in class, I've got a couple working ideas for a 3D print project. The deciding factor on which direction to go in will be determined by the print tests I have scheduled this week.      The sketches above outline my two paths of thinking for this project. Below, I will outline the two ideas and as stated above, allow the tests to be the deciding factor for which one I'

 3D Printing Test I created four shapes using the loft, shell, and twist tools. They are of varying difficulty, so that I will have options for a final print. I'm suspecting the twisted four-sided pyramid will have too much of a cantilever, but the other three options would all be safe bets I believe.  When modelling these in Rhino, I found the twist tool to be giving me a lot of issues and positioning the axis between the four views seemed oddly impossible. I only got the twist to work on one of the shapes but twisting increases the cantilever so in terms of 3D printing, the non-twisted options will work better anyway.   Update:     This week I will test 3 objects that are each designed for a different result. One will be to test cantilevers failing, one will be to test a bridge fail, and one will test a contour drawing. Below is the Rhino file I'm planning to use. (Note: the contour shape was created using the CageEdit tool)    

 

 Reverse Engineered Object Presentation

Reverse Engineered Object Render     Our OBDF 210 class was tasked with choosing an object to reverse engineer and then design and render in Rhino. I chose a carabiner because it's an object I use multiple times a week, and it's an object that is a great example of physics and engineering. I t's used in a belay system to keep climbers secure, and it's made to be extremely light and extremely strong while also being ergonomic. When climbing, you are very much relying on the carabiners to keep you alive. This one in particular has a locking gate mechanism.      I thought the carabiner would make for an appropriate challenge for my level of skill. There are some precise measurements, as well as some interesting contours and textures. By reverse engineering this object I learned quite a bit of on-the-fly problem solving in Rhino. The final render is still not perfect, (I would like the texture on the locking part of the gate), however based on my capabilities when I began t
