Print-Wave Metal Casting: A Different Approach to Metal melting

Here is a trick for knowing when the plaster is dry. After drying it, let it go to room temperature, then place your hand on the surface. If it feels cool, it's still moist. If it feels warm, its dry. (If it is dry it will feel warm even at room temperature). We use this trick all the time making ceramics.

no clickbait ,super informative and inspiring content -that is what YouTube used to be. Thank you!

This is the most underrated channel on you tube. This guy is awesome. Thanks for sharing the knowledge.

This is incredible! The mold process, the melting process, the information... What a great channel, thank you!

The "Brass" is most likely ZAMAC of some sort. It flowed very nicely which is charactaristic of ZAMAC.

What a truly inspirational video. Like all great ideas, they are so obvious once you are shown it. I have just started putting together the necessary items to build my own metal melting workshop. I have spent hundreds of hours watching videos and reading articles and no one comes close to how you do it.

Great video again! I hope I am not dead before I can reach this point of my Bucket List...

I"m just sitting here in my underpants saying "holy shit" repeatedly. Incredible. One of the most integral processes to modern humans industrialization has just been meaningfully iterated. so smart to recognize the application of the microwave.

Wow. Most underrated maker channel on Youtube!

Severely underrated channel and methods 👍🏻 great work.

That butter knife came out great. Maybe making a batch of tall "funnels" out of investment to make the pouring sprue longer, then stick them onto the moulds with bit of investment as glue? That silver metal the door handles were made from is probably Zamak, a pretty common zinc-based die-casting metal.

THE most significant use for 3D printers i have seen since 3D printers became an affordable thing.

Thank you for this video. Seriously. I've been considering how best to make a mold for some things I want to make, using many materials, but often using 3d printing to help create the mold itself, but I haven't been able to figure out which way to go about it for reliable and reusable results. This seems like the best method so far.

30 seconds in, based on what you said, I would have normally stopped watching the video figuring it was just hype. But since I've seen your other videos, instead, I continued watching, knowing that you do stuff I didn't think was possible. Not to mention things I don't think I would be willing to do. Like putting wet plaster right onto the build plate! WTF???? LOL Your videos are making me want to do things I am very nervous about doing. Though I'm still incredibly concerned about the danger aspects, and I don't have a microwave, so who knows. I would love a video on a deep dive on stainless steel casting. I heard you say that it can be done, but you aren't sure if you could melt enough for the butter knife. A whole video figuring that out would be of great interest to me. Thanks again for another great video!

The first 500 people to use my link in the description will receive a one month free trial of Skillshare! skl.sh/shakethefuture06241 Even though this method does not replace Lost PLA casting , it's amazing and has its own strengths and weaknesses. I can cast items that I could not before due to the size limitations of the kiln. Sure, there will be people who say that it's much easier to do sand casting. It might be. If you are into sand casting, all power to you. This is just another way. Some people might prefer to use plaster/investment molds over sand casting. It's great for people who just want to try out metal casting. This method has taken over a significant portion of my metal casting projects. It's great, and the future videos I'll be sharing will demonstrate that you can cast objects way more complicated than a butter knife. We are only getting started

I have been using this method for a few weeks know and it works wonders. You can add gating and a top feeder to the pattern to fill the mold from the bottom - minimize turbulence and porosity. Safety tip - don't leave the plaster for too long before casting - it will pick up moisture fast (anhydrous gypsum is used as a dessicant).

I think an accelerometer testing g-code would be great for popping bubbles of various sizes, as it passes through a huge range of frequencies.

This is a super cool technique. Great video.

Neat technique! I saw you patiently sanding with a Dremel. Bosch makes a cute 12V cordless die grinder that’s great for shaping and polishing metal parts. So satisfying.

Excellent work. 👍
