- In this video I will be showing you how you can easily turn 3d prints into metal by using the lost PLA shell method. This process uses materials that can be purchased at most hardware stores. These two way bolts were printed as a very thin shell, covered with Dap joint compound and then buried in sand and sodium silicate. Similar to the lost foam method, the thin PLA shells are vaporized as the metal flows into the mold leaving behind a nearly perfect casting.
Don't forget to check out my other videos for more casting projects!

Красавчик, Олега Певцова упомянул, молодец!
Would definitely appreciate seeing the ceramic cast version. Those always seem to work better.
Reference link?
Here it is! th-cam.com/video/v96LTfmtDPU/w-d-xo.html
@@robinson-foundry already watched it! The fiberglass was a neat idea and I'd like to see one with just fiberglass instead of the wire to see if it is a worthy replacement
the problem here was no burnout of the plastic before the pour
I watched first video of bust and decided to give it a go .. bought the 3D printer .. which is a art form all to its self .. got the forge and all supplies. This weekend making the tongs ,heat treat crucible , and give it a go .. thank you for inspiration to get off ass and try something wanted to do for a long time
That's great! Glad to hear it! You just have to stick with it and keep trying. I learned most of what I know through watching videos and joining forums.
this is the best PLA cast Video i have seen so far. No melt out required ;-). perfekt... i like to see more of this type of Casting
Thank you!
Those castings came out fine.
Thank you!
excellent. I appreciate the fact that you've got all the proper safety gear on as well with the leather and gas mask.
Really came out nicely. I'm interested in bronze.
I found it interesting how you used the joint compound and the sand mixture, very different from other casters who just use petrobond. Nice seeing other methods used.
You sir are treading on some thin ice, making me want to start metal casting again amidst moving to another city :D
Great work regardless, keep it up!
0:03 so satisfying to watch
LOL, "hollow tubes". Nice work!!
Thanks for sharing. I had tried a single wall pla part in sand. But your "bottom fill, vent thru top" method and using drywall mud looks promising. That encouraged me to explore that more. Your post is inspirational
You are a real master) 👍🏻👍🏻👍🏻
Thank you! You had a great idea. Please look at the new version. It’s much better. th-cam.com/video/v96LTfmtDPU/w-d-xo.html
Не знаешь чем обмазывает модели?
after coating the plastic parts with joint compound you need to sprinkle sand over the coating let dry than recoat again at least 3 to 4 times THAN when everything is dried and cured put the part into an oven to burn the PLA ( called a burn in ) till there only ash left ( you'll end up with an hard shell ) after your done doing so you need to take a air blow gun and blow the leftover ash inside the cavity till no more dust comes out of it, that will ensure that you have minimal shell contamination and your next pour should be looking almost perfect ! this process is called investment casting.
Impressive and highly watchable video. All good information without padding and unnecessary waffle. Well done
I’m blown away by the results of this method!!
Take the bolt heads off and make two and these would make superb dimpling rollers for sheet glass. There's actually a guy who made one of these on a lathe manually here on youtube you should check it out you would love it. Great work as always dude!
Great video. I've been thinking of getting into lost pla casting for a year or two, after watching people like VegOilGuy but you make it look much MUCH easier. Also much better job on the print this time, this really showed the greater detail your new process can achieve while still being easier than the slurry.
Amazing job again! Great to learn that you don’t actually first have to melt off the PLA!
Concrete sealer! You blow my mind!
As usual, amazing castings!
Do keep going my dude, your channel rocks.
Mate what can I say, you set the bar with every video you create. Well done and keep up the awesome work!
Im impressed with the jointing compound results, great work,
Well done, as usual. Your videos are well thought out, recorded wonderfully, and narrated beautifully. Keep up the good work!
Been loving the last set of videos. Would you think about doing a 3d printing and pewter kind of video? Most of us don't have access to furnaces, but melting pewter is something most people can do on a fire, on a stove, or in an oven.
That turned out awesome! Nice work! I'm always surprised at how well lost PLA turns out.
What a master of metal you make it look so easy would love try do this someday
Great video, I tried three times to make bronze sword and I failed. My sand casting what's not good enough, I mixed the sand with water and when I pour the liquid metal the water becomes steam and leave cracks and bubbles in the sword. I'm going to try your method of using sodium silicate with sand to make the mold.
You might have too much water in your mix. Are you mixing regular play sand with water?
Sodium silicate would work well for this. Make sure to use fine sand for the best detail possible.
Here's a video about DIY green sand. The mis works fairly well, but like Seth said, sodium silicate would get you better detail. th-cam.com/video/xFq9wpF0L8M/w-d-xo.html
@@KrakenCasting I used "river sand' that's how they call it in the store
@@robinson-foundry thank you
Love your videos dude, thanks for the great content!
next generation screw!
Great video and impressive job as always. And yes I’d like to see a bronze version of this project 😊
Very cool 👍 I have always wanted to try casting. Thanks for sharing!
What is the scale fidelity to the original part? Did you put a caliper on the printed part to compare the casting with? How much shrinkage did the aluminum suffer?
I want to know also. Aluminum is going to shrink anyway and then we have the plastic wall. Probably print the part at plus 2% and maybe print with a smaller nozzle like 0.3 but at a layer height still of 0.2? Just my thoughts. Let's hear from the author. Looks like a good method
I absolutely love your videos there amazing and I learn alot. Keep up the good work
Amazing video, as always very informative and something I will be trying shortly. Thanks. 👏👍
Brilliant as always! I think an aluminum or copper bolt with brass nuts would look even cooler.
Awesome video! You might be able to use a lapping compound on the threads to smooth out the engagements.
awesome and a easier technique. you are a master puddler
If you looking for more detail id recommend using paving sand (kiln dried sand) as it very fine and better for casting
And there it was stuff I didn’t know I wanted to know. Thanks TH-cam algorithm!
Great job, keep it up, waiting for more
Man what you do is really cool. But honestly I don't know how you have the patience and time to deal with such a time-consuming tasks and specially I'm sure not easy dealing with melted metal.... Good job
I have two suggestions for your next try (also I am curious to see if it improves the process):
a) add more small vents even to the pouring column because when you poured the first one a lot of metal got wasted due to the initial set of gas escaping. Add vents to the pouring channel at some degree so those initial air can escape. I would put two or three vents at different levels for each column.
b) I wonder if you achieve even better quality by heating up the mold first. Not sure if you would put it in another furnace or can just run a heat gun through it. But I know that currently because your mold is cold you can get some imperfection spots.
Good luck, I look forward to your next experiments!
amazing work.
I just said to my family that I rather have video games instead of a 3D printer for my birthday and Christmas. This is making me want one
Subbed for the potential ceramic cast version!
Yes yes yes. More Great content!
Wow turned out great as always. Would like to see the ceramic cast with bronze.
Great Video! That’s Cool!!
That's pretty cool. Would like to see the ceramic version
Great video
Awesome!
Really cool made!
I would love a (affiliated) amazon or similar shopping list of what you are using! Some of the products may be hard to find in europe tho, so i guess ill have to oversea it.
Impressive!
AWESOME!
You should try using plaster. As well as pre burning out the plastics. I’ve seen it used to a great extent. Just make sure you have places for the air to go
Thanks for sharing
Great experiment. I will see any video that improves on this one. 👍
Impressive
For finer details like the threads, how were you able to sand them at finishing?
hey can you try thinning out the compound with a little water and adding two coats or three of the compound I think you would get better castings
Awesome work! Would heating the aluminum beyond 1500°F help with the two halves joining at the top of the mold?
Can you reuse the sodium solicate and sand mixture for future projects, or does it become compromised?
My guess is not really. I think you can reclaim the sand by essential washing it in water removing the sodium silicate, but I imagine just reusing is not going to work well as the sand will be clumpy.
Yes to the bronze casting
Cool!
Ceramic would be intriguing 🤔 👍🏻
I’m still looking for sodium silicate but I’m stoked to try this. I’m shocked/impressed with your detail. Any chance you dabble with pure copper castings? I know they are difficult which is why I it would be cool to see how you tackle the issue.
+1 for good crucible-handling tools and protective gear
Hi Seth. Thanks for sharing this info. I too am getting ready for my first pour next week. Could you share how much sodium silicate you add to the sand? Looks something like a couple cups per 50 lbs but I'd hate to get this ratio wrong. Would you think that green sand could substitute for this method (no sodium silicate) or is the curing to hardness part of the reason this works? Am I wrong or was there less of the surface aluminum bubbling through the joint compound on this pour?
Definitely you should do it in bronze with the special ceramic :D
I think pre burning out the plastic in a furnace is ideal for lost wax/plastic casting but I'm not sure if that media would keep it's shape through firing?
I would like to see a recast of this project, yes. Thank you.
Would like to see the bronze casting. You do nice work.
Man, that is very cool. I have the plastic one but never thought you'd be able to cast it with that kind of granularity.
I wanted to ask you, Where do you get your furnace supplies, specifically, those vertical and horizontal tongs you use. I really like how you use them to move the crucible around. I'm new to foundry work and am still in Watch / learn mode while getting my list of things to get.
Interesting; I tried this before using a very similar process, but using zinc instead. I wasnt quite happy with the result since even the single wall print wouldnt really detoriate in a consistent manner; charring in some places and melting in others, leaving a very inconsistent surface and dimensional problems. It seems that with the higher temps of alu, the pla does degrade in a rather nice and consistent manner though; these castings indeed look great. You might want to try foamed PLA as well; might work even better since there is less plastic to move out of the way.
I wonder if the nuts would come out better if you had them tilted at 45 degrees, so just one spot on one edge was at the top?
Does this method work for hotter and denser metals like bronze or brass?
What would happen if you dip the 3D model into sodium silicate only? Would it form a hard shell on the plastic?
is rutland the same thing like in that red sand for casting
Did you notice any cooling shrinkage with the a356? Ingots of it don't seem horrible price wise. Or I could just recycle car rims I guess.
I wonder how well this would work with green sand. An other alternative might be dry silica sand with aluminum. I've done lost Styrofoam that way.
Brill video would be nice to see more usable items, or even equipment for camping in the wilderness
Great video and yes, please do it in bronze.
If you only made part of the bolt dual-threaded, it might be a good weight saving measure while still allowing it to work as a practical bolt.
Десятизаходная резьба, двухсторонняя. Первое видео на TH-cam from Oleg Pevtsov
You should print a velociraptor claw and cast it into metal, with individualized fingers and bones. It woul be really cool
I wonder if any other printable material would be better at this than pla?
The lw foaming filaments come to mind, but in general.... what burns the cleanest and easiest?
There is Wax PLA, pla mixed with wax designed for casting
Awesome video! Have you ever tried using high temp paint?
I need help with a ceramic coating. What do you use for that yellow stuff? Can you get it on Amazon?
as an avg. mind person, I just need to ask how to unbolt it as it is doing bolt from both clockwise and anticlockwise?
Fantastic job sir , I will subscribe and check out your other videos 👍
I think after 3d print, you should make the silicon mold to cast this model using the foam, foan easy to burn by the casting aloy
How would you recommend doing this method for a 25B32 chain sprocket? I've tried twice and failed. The first time I tried with no joint compound and I got the innermost part, but no sprocket teeth. The second time I used joint compound and got a beautiful spru and runner (like yours), but it stopped at the end of the runner. Didn't get to my sprocket shell before closing up. Aluminum was plenty hot enough. In a panic, I poured the rest into the riser. It didn't join, nor did it get the teeth. These are my first ever attempts at casting by the way. Starting to get discouraged. Any pointers?
But how well does it fasten? If at all?
Looks fantastic! Huge gob! It's an art, really, but nothing else.
What's the purpose of this hard work? Any practical use?
If metal is to cool, meaby hot sand wuld help?
хорошо что ссылку на оригинал оставил
How much aluminium did it take to cast them? (In kg please)
The two way bolts are cool and fun to look at and play with but are not very strong under torque and strip easy.
Génial for drone
