Right. It wasn't something that jumped out to me at first until I started looking at adding some design elements to my shipping boxes (without getting them expensively printed in a bulk order). It opens up a lot of options for cool designs, especially with how easy it is not having to do negatives or mold boxes or anything, just drop some silicone in and good to go.
You're absolutely right. It takes just a little bit more effort to model the mold area as a single volume to use as a subtraction. Definitely a clean way to get exact numbers with the object volume then. I'd probably still add ~5%-10% extra to the number for something this small since not everything comes out of the cup, some gets stuck to the stirring stick, etc. Always lame to have to mix up a second batch really quick.
If you used a really soft TPU you could get a decent result. Nothing sticks to silicone rubber though, which helps give a very clean stamp result. With TPU you're likely going to see print lines in your resulting stamp (which could be a cool look if that's what you're aiming for)
With TPU or even flexible PLA, it's way too firm and it really doesn't want to hold ink. It'll work, but the silicone is much softer and way better for making perfect stamps. I just went through this a month ago, wish I'd thought to use cast silicone.
The one in the video is this 5 gallon one: ( amzn.to/4bqL4ne ) definitely could do a smaller one for stamps, but I have a number of other projects that I do that are bigger and it's nice to have the volume.
Wow. Definitely didn't use any AI to write the script, but I did use Adobe Premier's Dialogue AI Enhance stuff. I had really bad mic interference (not sure what caused it yet) but the tool fixed almost all of the issues, I didn't know it could merge/blend the words though!

you could put a key or notch in the moulid to help the alignment, silicone looked really good !
That does look spiffy, but if you were using them as a top I would just leave them in the container and glue it together directly
Great video, never thought about molds for a stamp

Not sure how but you were recommended to me. First video in the list and even in my notifications somehow. Nice!
Not sure how it happened either but I'm here for it!
There is a third way, fusion 360 calculate solid objects volumes. You can model your rubber part by subtraction and get the volume like that.

2:22 could also use isopropyl alcohol, so it evaporates quickly.
That's another really clever and cheap option!
Make another one, but using your CNC
I'm curious how the final print quality of the ironed v un-ironed molds compare.
There was a very small difference in the final stamp itself, but only just barely noticeable. Not worth the extra print time.
Here's a photo of the result, the top is the not ironed and the bottom one is ironed: photos.app.goo.gl/dBbqdL1eLdNFJ7QA7
Why silicone? Would TPU be bad?

What vacuum chamber do you use?

Don't use water use sand
Oh that's a great idea!
It's making me crazy hearing you say silicon over and over when you are referencing silicone.
Two very different things
Oh wow, I didn't even notice I was doing that. Yeah that's a very different material.
Very interesting video, thank you. One thing, get rid of those gross white glasses!!
"There are a lot of cad software they can use."
Is someone using AI to write there scripts and not double checking the wording before recording?

There is a certain irony in your remark.
