Mold Positive Design

 










I think I still struggle with understanding how molds work in general, but I am trying to get there. I think part of the problem is that I picked the wrong shape for something new to me. I probably should have picked a more simple or familiar shape first so I could understand the process better before trying something more difficult. This shape was very mentally challenging for me.

At first, I was trying to make this a multi-part mold where the pieces would be put together, but I realized it just wasn’t working as one mold for the pot and didn’t really work at all. Because of that, I decided that the top piece of the pott would just sit on top of the bottom of the pott piece instead. I really try not to have any undercuts because I didn’t want any overhangs or areas that would get stuck in the mold. Because of this, some parts were broken apart with the idea that they could be reassembled later, but I now feel like it’s almost impossible to make this into two molds one for the ceramic pot and a second for the stand/ overflow for the water.


I ended up having to break it into the top of the pot, the bottom of the pot  and The stand on the side overflow. This change turned it into a candle holder, which I still think is cool. Right now, it is basically a bowl and a plate, with the bowl sitting upside down on top of the plate with a stand. 

 I would like it to be a pot like it was originally meant to be, but I couldn’t figure out how to make that work as a two-part  mold. 
The risks and challenges I anticipate are that it might not hold itself up very well, it could be wobbly, and it might be hard to assemble properly. Another challenge will be picking a colour. I’m hoping we can glaze it afterward.

not My First definition

I actually redid this tutorial at the beginning of the semester just to refresh my brain  It was fun. It’s how I designed our first project This project was inspired by an art piece that I did two years ago. It was two dream catchers that were going into each other. I always reimagined doing this art piece just because a I felt like It didn’t get justice because of the gallery where the show was. ghosted us and now they’re closed because of embezzlement lol. I reimagined it as humungous Installation because everyone kept laying underneath this piece During the gallery show open. So I wanted to redesign it and maybe use this design for this model for new proposals for my next art show. I found this pattern and a tutorial on how to map a sphere and make lines in between them, and then I built piping onto the lines, combined them all, added some texture, and rendered it.

CLAY FDM EXPERIMENT

  3-D renderings of printed design Redesigns on rhino redesigned for this assignment Original design from other assignment Original design for this assignment For this assignment originally I had another design, it was gonna be a baby swaddle that I made a long time ago out of fabric and put flowers into it. I thought it would be really great, but it took so long to design and I ran out of time with that one. And because my other assignment was failing, I realized I could still make a pot for the slip cast using the 3D printer instead.  My first attempt cracked at the bottom I believe this was because I touched it when it was still wet as well as as try to print the bottom instead of just clay at the bottom and then printing on top of the clay Second and third attempt came out way better   Then I experimented with the printer, seeing its capacity. I did this because I saw a video of someone turning ceramics into tubes and making them look like woven baskets, and I...
