3D Print & Scan
3D Print
I designed two models for this week, the first is a cube with my last name in it, and the second is a bench that is balanced at different levels.
Lyu's Cube
Because Neil's assignment requirement is to make something not able to make subtractively, I put my last name "Lyu"'s Chinese character into the 1cm x 1cm cube.
Honestly, I was considering doing an interlocking structure like many others as well, but I realized that it's actually possible to do that subtractively: you cut all those materials in the middle and basically leave a frame untouched. That's why I think something encaptured is not possible to do it subtractively: to do that, you would have to break the outer walls.
But to see this result, I would have to use transparent print material. But unfortunately, we didn't have that left at the Harvard section when I printed it. Therefore I used a random color.
(un) balanced bench
Depending on how much weight you put on both sides, the bench balances on different levels. I want to build a bench at some point, so I need this little 3D model to guide my design process.
My first iteration was very simple, one surface and two sides:
My second iteration was more detailed, I put four legs on each side, also the horizontal bar at the top can be attached & detached. But I noticed since those gaps were two tiny, the top part ended up attached with the rest, which is fine as well.
Scan
Because I got COVID this week, I used the LiDAR sensor on my phone (iPhone 13 Pro) to scan the AirPods case. The result isn't very bad. But it's interesting to see that it deformed a bit, especially around the shadow. Was it because my case was black as well, so it confused the algorithm?
