OBDF 311 Reading Week Update

Most of the work I did this week was setting up the CNC machine. Quite a few of the settings required quite a bit of tinkering.











Results:

I found that one of the kerfs broke upon bending. I also found that the bend was not that gradual, and this may be an issue of size (being such a small model/test piece)



Moving forward, something I want to try is switching to bending using a straight lattice hinge (sometimes also referred to as a "living hinge"):

I did briefly look at other types of lattice patterns, but I found that since I am only trying to bend in one direction, this may prove to be the most sturdy for what I am doing.

Typically, these are done using a laser cutter and I am thinking that with how my progress is currently going, I may want to switch to doing this project entirely with the laser cutter instead of going larger scale. It was a bit of an ambitious project in the first place, but I have also noticed that most of the items I wanted a place to store in the first place was mostly made up of small/light displayable items anyway. (Admittedly, these items are mostly Nendoroids, plushies, and other figures).


These are some of the websites I'm using to look into how to design the lattice hinge:

I'm hoping that by making one good lattice hinge design, I can apply this to all 9 of my curved pieces rather than attempting to design kurf cuts that will work to each individual curve.

Reverse Engineered Object: Progress II

Image
If there is anything I learned from this project, it is that rounded out corners make me want to perish. I haven't been able to find a way to smooth out a corner using the fillets, as it would fillet one direction okay, but then when filleting the other way it just creates another corner. Below is an example of what I mean by this. Please send help, I just want my corner to be perfectly smoothed out. I've tried to fill in this space with a section of a sphere but that also held no results. Besides that, I have to admit that my motivation to complete this has been lower than it should be, but I have the circuit board (mostly) completed after some trial and error. I found that if you want specific patterns on each side, you have to explode the object and set the scans (as I was not carving out every little detail) as one trimmed surface. Other progress includes the relative completion of small components. The additions needed for these are mostly decorative, such as the numbers o...

Project 2 - Mass Producible Object Proposal

Image
For project two, I want to expand on my current project, but I think that I should finish it up closer to the end of term.  I dramatically redesigned the edges to contain straight edges so that they are easily stackable and portable, like an Ikea shelf would be. In terms of naming it as a product, I would advertise it along the lines of "geometric dragon bookshelf" because I want to keep the name relatively literal. I ended up making a lot of progress on redesigning the bookshelf to be cut exclusively on the CNC machine. I was pretty torn over designing the curved shelves, so I approached it with the intent of using only straight boards with diagonal cuts. Until then, I'd like to work on a project that is relatively small scale but will still take up the rest of my semester.  When considering mass-production, the first thoughts that come to mind is something that can appeal to an audience. So for this project, instead of making an object designed for myself, I want to cre...

Parametric Structure & Animation

Image
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.
