Making a Measuring Cube - EXTREME MEASURES - bronze metal casting at home - 3d Printing Lost PLA
I will be making a measuring cube out of bronze using the lost PLA method. I started this project by 3d printing a model in a plastic called PLA. Then I coated the model 10 times with a ceramic material called Suspendaslurry. After the ceramic shell was completely dry I placed it in my kiln and melted out the PLA plastic. At 1500 degrees Fahrenheit the ceramic shell becomes vitrified, turning into a ceramic that can withstand the heat of molten bronze. I melted the bronze in my homemade keg foundry furnace and then poured the liquid metal into the ceramic shell mold. This is similar to the lost wax casting process.

You should buy a rock tumbler/ polisher. That would work great.
Very good idea
But it takes so long to get polished rocks :(
Or build one!
@@maximeduchalet4662 ok but I'm expecting him to alloy gear metal forge it, then hob the gears.
a brass tumbler/clearer for reloading would probably work well too.
I did bronze casting in college - incredibly satisfying, but a lot of work. We used the lost-wax process (cire-perdue). This 3D printing method looks fascinating.
I went to college so long ago I think bronze hadn't been invented yet. :)
Ha, that camera magic with the gloves was great! Nice casting, too. I love functional projects.
You have created something that your descendants can still marvel at, with your name on it and a small inscription, they can still remember you many years later.
Man, I've never seen someone use a slurry like that. Definitely going to look into it when I get back into casting. I'm already stocking up on old radiators and such
While I don't think it would have worked with this project, I really like what BigstackD does with Petrobond. If you haven't seen his channel, check it out. It's awesome to me that for a channel where no one says a word, the dude is freaking hilarious! If you haven't seen the channel, check it out!😎🤙
@@TheRisskee he doesnt seem to like doing lost castings, Im not sure why. He does the odd styrofoam lost casting I guess. The petrabond seems really finicky and I feel like his castings never turn out quite this perfect. My theory being that the molds are inherently forced to be cold, so the metal doesnt cool evenly. Love that Aussie tho
Suspendaslurry is AMAZING. But it is expensive. I just bought some but I had to hide it and the price from my wife. Shipping was about $300.
The detail you capture in your castings is amazing. Thanks for sharing.
Was the measurement still accurate? I worked in a bronze foundry years ago and I would have been send home when wearing those shoes! We wore wooden shoes only as they can be kicked off and offer some seconds before burning through when your cast leaks and liquid metal spills out. Cool shape, thanks for sharing, stay safe.
Never heard of using wooden shoes.
What was your favorite part of working there? Sounds interesting :)
Which measurement would it be accurate to? Tablespoon to ml isn't accurate in the first place.
@@edwardssistershands Well one tablespoon is 14.786788602728 ml. I don't know any recipe in the kitchen that would be measured with such a device that is ruined by 0.2132114 ml of something that inaccuracy you have with pretty much any kitchen measure anyways. Especially by volume.
@@carpediem5232 Compounding errors :)
Whoa, this looks sooo cool 🥰 I got a 3D - printer for architecture model printing and that model itself had been on my list for a while as well . I didn't even know one could use it along with ceramic slurry to make metal castings, that's so cool to see!
As a cook, I love this so much. It's definitely functional art. I would definitely use this cube.
It measures well but is too easy to spill liquid.
I was thinking about how impractical and bulky this would be in the kitchen. Stacking measuring cups are far more practical but this looks really cool.
@@Been.Here.Since.2007 why do you need multiples of a measuring jar or cup? one is not enough?
@@jurekmc There's 2 types of measuring cup. Dry and wet.
@@Been.Here.Since.2007 with plates, a scale and a measuring jar(idk how to call it, sorry for bad english) its more than enough for me but i get where you are coming from.
Beautiful. The fact that it caught even the printed lines is amazing
I just loved this casting method! Thank you for sharing!!!
I love the pour the detail is so perfect you could see the over spill of glue where you joined the 2 parts
...as a Kitchen gadget groupie, I am thunderstruck!!! Thank you for this
Thanks for tuning in to another installment of, “words I didn’t know before!”: 1. Sprue: A channel or funnel through which metal or plastic is poured into a mold. 2. Vitrify: To convert (something) into glass or a glasslike substance, typically by exposure to heat. 3. Lost PLA Method: The model is placed in a plaster mold and the mold is heated until the wax liquefies and flows out of a hole in the bottom (hence the “lost-wax” part of lost-wax casting). Liquid metal is then poured into the mold, which flows into the imprint of the design left in the baked plaster. Tune in next week to find out precisely where my vocabulary was lacking (or REMEDIAL for the kids following along at home!)!
Nice I also never know this word
youll learn a lot more if you stay in these spaces.
I did know vitrify, not sure why, but the other 2 were new to me, as well.
ok
The detail preserved by the casting is nuts! If you had told me that was bronze color filament, I'd have believed it.
Another beautiful casting well done! Thank you for clearly explaining the process
This was a very satisfying video to watch, and I really like how the cube came out at the end. Kudos to you Mr. Robinson.
It's incredible to see how you made those. Somehow this kind of videos are very calming.
They are, aren't they.
Don't be so hard on your self, you did a great job on this. I have not seen anyone do it better so I think that is a great way of scaling how well you did. Thanks for the video, always fun to see what your going to work on next.
Wow, huge improvement to the typical lost pla castings I've seen.
I really enjoy that you talk through every step. I watch other similar channels, but they're always just gestures at most. This reminds me of this old tony, but with metal! (and less jawbreaker references)
That was absolutely totally awesome!
Every time I watch one of these lost PLA videos, my dumb ass hears "cake furnace" and then a few seconds later I see the furnace and remember it's a keg.
I heard that too, and I didn't question it. I don't know the jargon. Thanks for setting me straight.
There's just something about you that's so cool. I bet you're a really neat person
Great Job! It looks fantastic.
Literally great work .
Super cool design! Way to go!!!
A very professional finish!
Wow! This is amazing!
looks great, i printed and used some of these myself. for the finish, i really liked how smooth you got the bottom with the large disc sander. i would do the same with each of the sides. with their rims all the same smooth, shiny metal, it would contrast quite nicely to the rest. and you could even get a more elegant look if you sand the rims until the edges are pointy
drive.google.com/file/d/1_DNK01kUjizxYDQe_xFU9l_cgUkali9b/view
Also be an interesting contrast if the insides were highly polished, [vibratory medium polisher, perhaps ?] and the base and outer corners were left matt finish. That would be perhaps a little easier to clean if used for actual cooking measurements
I'm glad you tried too bc it's a pretty cool measuring device.
Great job on that!
That Sir is piece of art. Any top baker would be proud to have that working piece of art in their kitchen.
Turned out great. good job
Looks great. Makes me miss metal pouring and metal works I did in college.
That really came out freakin awesome
Love it! i guess lost pla could be done. but this is the first time I watch it being done.
Incredible work well done
Great video and loved the idea of using that slurry. Cube turned out pretty cool. In fact, am ordering one from Amazon to get rid of my crappy collection of measuring spoons and 1 cup to 1/4 cup measurements. Keeping my Pyrex 2, 4 and 8 cup sizes. Thank you.
As a cook, you get 2 thumbs up form me! Also, your lost PLA & Suspendaslurry videos are most awesome!
Beautiful work
Cool idea!
Fantastic job!!!
Great piece of work.
Thank you. You're a Master craftsman. Keep up the good work!
This is amazingly nice! Good job bro 👏
Truly exceptional work your PLA casting is becoming more exquisite every video you know what they say practice makes perfect 👍🏻👍🏻👍🏻👍🏻😊😊😊😊
Excellent job.
That is a superb piece.
What a beautiful final product. I was worried, too about the thinness of the walls. Bronze is so heavy and that spruce weighed a ton, I bet. I was happy for you when it came out so nice. I think the finish of the casting might have been improved by polishing the PLA. But when you focused on the texture from the model I thought it was really nice, too. Thank you for sharing your skills.
drive.google.com/file/d/1_DNK01kUjizxYDQe_xFU9l_cgUkali9b/view
What a lovely object.
That's a beautiful thing you did, regardless of the fact that for the task of measuring, the printed cube was already perfect as is.
No, there's definite improved utility from having it cast in bronze. PLA isn't food safe, so you shouldn't use it for utensils like this, and his bronze measuring cube can go in the dishwasher! Plus of course it looks way more stylish
i have no idea how safe PLA is, but i suppose there are other printable materials which are food safe. but you are absolutely right to love it. it's awesome. @@HaralHeisto
Ngl that transition of putting on the gloves was really smooth
that imperfect surface finish to me makes it look better
Really awesome man, great job
THAT was way cool!!
Cool device and idea. Thanks for sharing. Weekend Stuff
A great skillset!
Nice as always
What a great idea
Great video and well presented. Cheers man.
Wow!! That is an amazing device!!
Always had a fascination for casting
best chef paperweight ever!!
👍 like it. You have the skills, foundry and a place to do that.
the ceramic stuff when liquid seems delicious ngl
Great job.
That is bad ass! Would love one of them.
Amazing!
I am impressed. Great channel and content.
Once metal 3D printing becomes more publicly available people are gonna go crazy with their inventions and projects
I love it broh! It’s something that I didn’t know that I needed.
Loved it
Very nice!
I would purchase this and many more of your other projects awesome job
Well done.
love it !!!
That's a job for a rotary tumbler if ever I saw one, great job.
I'd think a vibratory tumbler would be better as the polishing media would be in contact with the entire part constantly, unlike a rotary tumbler. I don't think a rotary tumbler could even get media into the deep crevices to polish them at all.
@@supergiantbubbles If you used only large media you would be correct but rotary tumblers work with anything from pebble-sized media to talc sized and paste type media. Second, you can mix media size in a rotary but not a vib, the small particles just fall to the bottom in a vib, but not in a rotary. A mix of large and small media would have done the sandblasting and polishing steps in one process but only in a tumbler. 👍
what a great work....
"80 thousandths of an inch" sounds so complicated compared to 2 millimeters. It always gets me. Thinking if people can really imagine some tiny thousandths of something. Either way, super cool project. I saw this measuring cup being used by the "as seen on TV" guy. It didn't seem overly practical, at least in the way he used it. But making a bronze version is pretty awesome 👍 and the quality of your casting is superb.
or just 8% of an inch. Do basic conversions escape your capacity? Lol
@@THESLlCK Or maybe just 2 mm. Do basic units escape your capacity?
@@JuanCLeal complain more
I suppose thou(sandths of an inch) is a weird unit if you don't hang around US machinists, but there's a few intuits for it: a hair is a few thou, a playing card is about 10 or 12, the wire in a paper clip, something like 40 thou. While no one could feel a difference in width between 40 thou and 41, it's likely that you'd feel a burr 1 thou high on an otherwise smooth surface. Imagine a fine hair on a glass plate. 1 inch is not really long, but its long enough that 1 thousandth of an inch is tiny, but in some contexts, still very much perceptible. Just my 2c. Have a good one.
@@THESLlCK I prepared this bucket of ice cold water for you 🪣 That burn has to sting pretty bad.
Pretty cool
That's so perfect cast.👍👍👍
That was Excellent 👍👍💛💚
Wow, thank You for Sharing...
I really like this pattern.
You ever thought about an acid bath, it'll clean it up and may help get rid of some lay lines and tool marks before you polish the pieces up. I love these craftsmanship channels. Keep up the good work
you are no joke, the cast master
Cool product
Vato, eres un artista, uno bueno
2:52 forbidden tempura Maaaan that C U B E turned out beautifull
Whaaaaaaat...I need one of these!!!
Having the ceramic shell helps a lot. Not only in allowing the original PLA template to melt out and leave a perfect negative void, but also with the pouring of the cast as it's perfectly able to withstand the heat/pressure of the molten alloy at the temperature required for it to remain liquid long enough to fill every space. The results speak for themselves.
Really interesting, neat hobby.
That's impressive. Surprised how well the letters showed up
Seeing you use your 3D printer makes me want to play some Astroneer!!! Thanks!!! 😄
The glove trick was sweet.
Very unique idea mate 👍
That’s wild
Great video. Makes me want to build another furnace and start casting again! Just curious, did you print the measuring cup slightly oversized to compensate for shrinkage?
Forever cursed to make slightly fewer brownies!
@@NeonThoughtBox hahaha that’s hilarious! I was just curious, but going back and reading my comment now makes me feel like such a casting snob haha. Totally didn’t mean it that way. Sorry Seth! Good luck with your brownies…
What % of shrinkage is there when the metal cools off, and how come the ceramic shell doesn’t come off more easily if it’s actually a different size to the casting?
@@thechumpsbeendumped.7797 ceramic shell shrinks as well and even more during firing. It is basically sintering
@@thechumpsbeendumped.7797 Guess it depends on the specific alloy used.
great project, awesome model/piece, kick ass video! =D
