How to copy parts from car in resin using Agar-agar, YouTube.

[WorldOfCarModelsCraft]

Want to share  the method for replicating car wheels in resin using agar. This video tutorial provides a step-by-step guide.
"After a long hiatus, I've finally produced this video. I'm still learning new techniques in photography and videography, aiming to revive my channel that went dormant many years ago. Ultimately, I'll be focusing solely on creating model kits. This video is just a trial to reignite my skills and passion for photography, filming, and modeling. Any criticism is welcome as I strive to improve wherever necessary. I understand that AI reading out text might not be the best way to convey thoughts, but for now, it has to suffice as it is. Thank you in advance for everything."

That's a cool idea, never heard of Agar gel. Good luck on your videos!

Agar is primarily a consumable food additive in the US today.

https://en.wikipedia.org/wiki/Agar

https://study.com/academy/lesson/what-is-agar.html#:~:text=Agar is a gelatin-like,want to culture and identify.

We used a nutrient-enriched version called agar-agar to grow bacteria in high school science classes.

It's not a preferred material for mold-making that requires very fine detail-capture, and for molds that can be used repeatedly over time.

There are so many engineered materials that are made specifically for the purpose, like silicones and urethanes, I fail to understand the motivation to use oddball stuff for mold-making.

I agree with Bill. There's a ton of products to use for moldmaking that are made specifically for that. Very readily available, too. Most Hobby Lobby stores carry everything you need! Back in the '80s, it was a different story. Here, in Denver, we had to go to a plastics wholesaler, and walk up to the City Counter!

Hi, thank You for replay, I can't find it in USA sites but this is in general  used in dentistry for copying.

I think that is the older mold making material to make impressions of the mouth, to make plaster casts. Since Agar mix contains a lot of water, it will shrink and dry up if not used immediately.  I don't think dentists in USA use it anymore.  I had multiple crowns and implant done in the last 10 years, and the dentist uses some sort of 2-part RTV rubber for taking those impressions.

Using agar was an unusual approach but considering you're only making one duplicate, I thought cool why not. You’re going to toss the mold away when you’re done. I thought the video and technique was informative enough for the average modeler to understand. Regardless of material used.
