Easy lost PLA metal casting │ How to turn a 3d print into metal │ ASMR

Welcome to Robinson Foundry. In this video I will be using the lost PLA shell method to turn a 3d print into an awesome solid aluminum casting. I started by printing the model on my 3d printer and then coated it with joint compound. I then buried the shell in sand and sodium silicate and poured in the molten aluminum. This vaporized the PLA and leaving behind an awesome casting.

I used to do some lost foam castings. I would use joint compound thinned with water to about like milk. and spray on several coats letting them dry between coats. Then I would pour a base layer of sand into my bucket place my part in and pour plat sand around the part. After that I would tap the bucket with a mallet to pack the sand once it was packed down pour my metal. Worked great. I made tons of parts and no water glass.

I have tried a couple different types, but the powder that you mix with water that contains plaster of Paris is the best. A lot of the pre mixed varieties have polymers in the mix (usually some sort of vinyl) and they don't work as well. I'm not sure if it's the vinyl, or some other ingredient, but the pre mixed stuff had tiny pits and dimples in the surface finish.

If you do this same model again, I would suggest that you cast it upside down. The gate can be much smaller than the feeder/riser so you could have a much smaller defect on the top of the head.

@1495978707 3 жыл бұрын

In fact this is preferable. You want controlled gradual flow, not sloshing, and this is achieved by constricting the flow before it reaches the model

Yeah, the lost detail across the top of the head was pretty tragic.

A few years ago, Grant Thompson from TKOR made a video where he did this, but with styrofoam models. I've always juggled around the idea of doing that, but with 3D prints, and it looks like your did it first and perfected the idea with the layer of plaster to get all the intricate details. Excellent work! It looks great!!!!

Very impressive. Another version of this is being used with powdered steels. The print gets placed in a steel tube (cannister). The outside gets filled with 1085 and the inside with 15n20 or 1085 with 5% nickel. Its heated to forging temperature and compressed in a hydraulic press. The pla is organic and burns off as carbon. Some very detailed mosaic patterns for knife blades etc are being created. Its very new and likely the next big thing in mosaic pattern welded steel (damascus). Thought it might interest you.

Great work! I like this molding method, I will have to try it. One note: don't load your crucible cold like that. The aluminum expands as it heats and it's a great way to crack your crucible. Throw a little in the bottom and let the rest preheat on the furnace vent, add once you get a molten heel on the bottom.

For anyone who cares. "MOST" Cast aluminum is a high silicon based aluminum alloy, which lower the melting point and helps make it flow much easier. This is what makes it ideal for casting. You can buy silicon from eBay, crush it, and add to your molten aluminum to make your own allow that flows easy
