Algorithmic Surface Model for SLA Printing

Revised Design in bounding box:

Some feedback I got from the class was to consider the direction that my design is going towards. In particular, which way the "arrow" part of my design faced. I decided that I liked it with the box shape facing up.

One critique was to improve the support for the corners, specifically the way some intersections hang with little support. Because I'm using a lattice structure, Bryan mentioned that I could deal with delicate parts by increasing the thickness of the print or else I could use an underlying form as a support structure. Since we will be using clear resin, I plan to use this feedback to create a low relief design for final print using an underlying form.

Along with the feedback regarding structure, it was mentioned that the way I set up my piece made it so that new iterations would be fast without changing the surface design. This came with the idea to explore more forms.

Overall, I made 14 shapes using the revolve tool in rhino, but since 5 of them were polysurfaces, I had 9 surfaces to choose from. I scrapped the polysurfaces because trying to work around it would be a hassle regarding the surface morph function in grasshopper. I went for a vase shape because I wanted my print to have a practical use.








Below is the one I ended up enjoying the most, but depending on feedback next week I might go with a different model.

Algorithmic Surface Modelling + Animation

Tile design: Test Shapes: To experiment with tiling, I initially tried using a cylinder and a shape similar to the class demo to make sure my algorithm works. For my animation, I tried to tesselate my design to a series of lofted polygons, but I found that when I tried to input the loft into the surface morph, it gave me an error saying "1 value inherited from 1 source... Null". It didn't matter whether or not the loft was connected to the rotate axis (between polygon and loft) and I couldn't manage to make it work even when using mesh brep or the brep parameter. Even baking this surface did not help.  I found that using this shape gave me two main errors: 1. Divide Domain: Data Conversion failed from Brep to Domain²  2. Surface morph: Data Conversion failed from Brep to Surface Putting mesh brep between brep and divide domain² helped, but it still had errors regarding the V domain values being 0. Oddly enough, this exact same algorithm worked when I replaced polygon

In class tutorial animation: My own spin: I found that it was a really straightforward process, especially since I've had experience already with making short animated gifs. What I found to be really nice was that instead of a choppy gif made up of 3 or 4 screenshots, I was able to create something really smooth. I also found that rhino's naming structure for saving the .png files made it so I didn't need to worry about organizing 180 or so individual images. The hardest part was thinking up a new object to create and when I did, I found that I had to make individual brep's and play around with positioning a lot.
