About 2 weeks ago in RJ’s class, we were showed a few different design applications and had to learn how to navigate and create 3D models from scratch. I’ve personally always wanted to learn 3D modeling, so I eagerly dove into the assignment. Not long ago I was highly considering architecture because it’s always been a personal interest of mine, so I familiarized myself with an application for the Ipad called Shapr3D. Since I had a decent understanding of modeling homes and furniture in this application, I was able to catch on to things pretty quickly. I came up with the idea of creating a hydro flask with a detachable pill compartment built into the foot of the bottle.
The physical appearance of this bottle came out beautifully, but I never really though about the challenge of making it fully functional. I spent at least 5 hours going back and forth, remodeling nearly every aspect of my design. I had to restructure the top of the bottle and extend the bottle cap so that I could add threading to each component to make it air tight. The threading itself was quite difficult, but I was able to find a tutorial that gave specific instructions on how to construct it. For the pill compartment, I had to offset the edges and evenly align 8 pill models within the smaller circle that I offset from the original base. I then raised the middle circle and subtracted the pill models from that component to get the pill storage compartment that you see above. The next challenge was making the base detachable. I initially tried to replicated the threading component that I added to the bottle cap, but kept running into problems when I tried rescaling. Then I got the idea of adding 4 small notches that click into place, which worked beautifully.
When models like this are printed, there are a lot of things that can go wrong in terms of connection that you have to account for in your designs, like slightly offsetting edges and determining the best functioning feature for a certain product. The same goes for any product modeling. You cant just make the product look good, your design has to accomplish what you set out to create in a functional sense as well, which can be very difficult in certain cases.
Last week we started to work on parametric modeling. Parametric modeling is an approach to 3D CAD in which one captures design intent by using specific features and rules, and this allows users to automate repetitive changes.
For the assignment, I chose to submit 3 parametric wooden table designs. I designed these tables through Shapr3D but wanted to take it a step further in terms of looks and materials, so I exported them into a desktop application called Fusion 360 where I was able to add shadows and specific textures to smaller elements.
Though these parametric table designs came out great, I was simultaneously working on, and am still working on, a much more complicated project that I wanted to submit for the assignment. I’ve always wanted to create a company that creates affordable, customizable prosthetics for child and adult amputees, so I started doing research on some of the models currently out there and things like mediolateral balance control. When looking at some of the current products, I found a lot of variations of 3D printed exoskeleton coverings that had some crazy patterns and designs so I tried to recreate some of them. Sadly, I never even got to the exoskeleton coverings because designing a fully functioning prosthetic with every little part, piece, and screw was extremely difficult, especially with a product where motion is the most important factor.
As you can see, there are a lot of components to this design that require exact dimensions which I have yet to perfect, or have even come close to perfecting. Everyday Im learning more and more about 3D modeling and the different applications I can use and what I can use them for. I am confident that by the end of this semester I will be much closer to successfully creating a fully functioning prosthetic.
This week in class we’ve been focusing specifically on the visual aspect of 3D modeling in Adobe Dimensions. I am still currently putting the final touches on my assignment so unfortunately, I do not have a visual representation quite yet but, this application takes the appearance of your models above and beyond, which is very important when presenting your product to a client because although you may be able to see the final look clear in your head, most other people cannot. The application does a fantastic job of adding shadows, materials, lighting, etc. and even allows you to place a background setting behind your product and match certain visual features with the background image. I think this application is super cool and will definitely be using it in the near future to present my product design work.
