Making a Measuring Cube - EXTREME MEASURES - bronze metal casting at home - 3d Printing Lost PLA
HTML-код
- Опубликовано: 28 сен 2024
- 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. :)
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 :)
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.
@@ReglazeRX 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.
@@ReglazeRX 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.
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.
There's just something about you that's so cool. I bet you're a really neat person
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.
the ceramic stuff when liquid seems delicious ngl
I'm a 3D printing and metalworking mechanical engineer and I learned stuff in this video, thanks! Great work on your casting! Great to see some professional-level technique used in a RUclips casting vid.
Personally I might have smoothed the 3D print a little first... but that would have been a PITA and you did a great job anyway.
To remove the ceramic shells - I've actually re-furnaced my pieces after doing the initial cleanup. The shell can fall off in circumstances like that, due to differential expansion. Might have saved you some sandblasting time.
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
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
"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.
That's impressive. Surprised how well the letters showed up
that imperfect surface finish to me makes it look better
Wow, huge improvement to the typical lost pla castings I've seen.
best chef paperweight ever!!
A very professional finish!
Seeing you use your 3D printer makes me want to play some Astroneer!!! Thanks!!! 😄
Always had a fascination for casting
I'm glad you tried too bc it's a pretty cool measuring device.
Truly exceptional work your PLA casting is becoming more exquisite every video you know what they say practice makes perfect 👍🏻👍🏻👍🏻👍🏻😊😊😊😊

Maaaan that C U B E turned out beautifull
I just loved this casting method! Thank you for sharing!!!
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. 👍
You know you have to get this thing up on Ebay and make another one since it needed to be 2-3% bigger. Let me know when the auction starts! Cool project.
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.
The glove trick was sweet.
Looks great. Makes me miss metal pouring and metal works I did in college.
I really wish you had a webshop? I’m sure your puzzles etc could be a nice little business. I would certainly buy some of your work. I love it. Thanks for the videos.
That really came out freakin awesome
Actually this Cube it’s difficult design you do great job 👏🏽👏🏽👏🏽
This is amazingly nice! Good job bro 👏
Another beautiful casting well done! Thank you for clearly explaining the process
What a lovely object.
Cool device and idea. Thanks for sharing.

I like how the furnace is a repurposed keg
Wow!! That is an amazing device!!
That's so perfect cast.👍👍👍
I would purchase this and many more of your other projects awesome job
That was absolutely totally awesome!
Look into 3M radial bristle discs. Those on a flex shaft could be the ticket for the hard-to-reach areas.
Looks sick! Do you turn the mold to the sides after your pour in the molten metal? Or did it nicely go in by itself and covered all the corners and details? I'm surprised by the high definition of the models in this video and some of your previous ones as well. I always thought that keeping such fine details is incredibly difficult, but you make it look easy!
Thank you! No, I didn't turn the mold at all. The metal was fluid enough to completely fill it. Ceramic shell is amazing stuff!

Turned out great. good job
red liquid metal is just mesmerizing to look at
try adding phosphorus for less oxidation during casting and 1 - 1,5% lead for better castability (+ food safe clear coat finish)
let the casting cool on its own, it reduces stress and prevents cracking
and get some propper shoes :D
I don't know if it'd help in the future but if you are using cura for the 3d slicing, it has a mould mode and will produce an inverted print.
I am a plant supervisor for a investment casting fan as well as my father is the owner. This is exactly what we do, except we focus more of cost savings and cheaper materials.
Nice. Thanks.🤩👍 Thailand.
the perfect cube is the oddest shape. this dude
THAT was way cool!!
Great piece of work.
Neat project and great commitment.
But as far as making an artful product, a useful tool or efficient process...it really doesn't get very high marks.
A worthwhile trophy, but as a gift I would put it away into storage as soon as it's polite to do so.
Excellent job.
Beautiful work
Would be curious to know just how much plastic you melt out vs burn out, would be easy to calculate by weight. Glad you're conscious enough to do it this way.
Extraordinary job. A vibe finisher might be the answer to polishing it. I have one where we use little triangular stones in it about 1/4 inch in size. These were chosen to have sharp points and corners to get into inside corners. We use it for all sorts of polishing and deburring. All operations take a few hours. If you want to send me a sample I would be glad to try it for you no charge of course. I don't do casting but enjoy your excellent videos. JY
I was on and off about clicking on this video, but the pun really pulled me in.
Also could have used a puck of gold alloy or bronze and milled this cube shape for best surface finish.
Cool idea!
I could imagine myself measuring something with this, get a hand cramp or something and drop it on my nice bowl sending all the contents all over the place.
Love the keg forge! #innovation
Nice as always
I love it broh! It’s something that I didn’t know that I needed.
Now you need to divide the dimensions of the printed cube by the cast cube. Then enter that into your 3D printer scale setting to over size the print so the finish casting it’s more accurate in its measurements of volume.
For the pieces of casting inside a concave surface.
Pressure washer.
You aim at the lip of the casting and try to get the stream to go under the casting.
It will usually pop right out
Also, very cool measuring tool
how can something be ingenious and impractical at the same time?
Great job.
Cool measuring cube. I like😊 you need a loin slave. I hear they enjoy scraping dirt from around dinosaur skeletons. Just tell them they are digging out an ancient artefact and give them a plastic scraper. Keeps them busy for hours🤣🤣🤣
Very nice! But can you make a cake using it's measurements?
Really interesting, neat hobby.
Very nice!
Woah! It's like a 3D print, negative!
There is a wax filled pla that we print with. Burns out super clean.
Great. You could have done a acetone smoothing to get smooth surface on 3d prints. It will help to remove layer lines, also make easy to remove pattern from sand and also easier to remove ceramic debries from the casting .
That is a superb piece.
Amazing!
try using a jack hammer with a flat head for removing the shells, the vibrations should make it pop right off.
I just love your videos!!! i've been wondering, did you scale up your 3D print to prevent the retractation coefficient of the bronze and get the correct exact size from the CAD model?

This is a fascinating object on many levels. Thanks for sharing it.
Pretty cool
Great video and well presented. Cheers man.
Great Job! It looks fantastic.
Wow, that looks great! Pretty much way above than any other casting videos I've seen here.
I do wonder if there's a suitable SLA resin that could be used for this so you could try and do really fine detail castings, since we know your casting method is up to the task!
Thank you! Yes there is. I’ll be using it in upcoming videos. We’ll see how well it works.
If using a harder material, a needle gun works great for getting off all of the coating.
what a great work....
To get a better surface finish use an sls 3d printer cos there will be little to no layer lines in the final cast
Where you pour the casting would it be prudent to figure out a way to make that table or surface vibrate to help get the material to flow better in some circumstances
everyone: ooh this looks cool, i should 3d print it
robinson foundry: *hold my furnace*
By no means am I qualified to say anything because I've ever done anything like this but my first thought about that shell being difficult to remove was if perhaps you sanded down some of the 3D printing layers to reduce surface area and thus making it easier to remove from the metal. Just a thought, could be wrong though.
If you use steel wool between the layers of the suspendaslurry , it will minimize the cracks
Dude... you are dope!

This is really cool. Have you considered expanding your Etsy shop to include some of the various things you’ve made on this channel in addition to jewelry? Please let me know if you’re considering selling this or making more to sell, I would be super interested in buying one!
Incredible work well done
Your finish could have been improved at the pla model stage by some tricks to smooth the model out such as 3d print settings and things like heat gun or acetone (not sure, look into it) but you can smooth out your 3d prints with post production techniques.
If he only 3d prints that might help, but if in the end he's going to use it to cast metal he's going to sand it down anyway, so it's not all that useful to him.
Loved it
Very unique idea mate 👍
