Just fantastic. My cousin recently used this technology to cast an iron cylinder block for an old 1904 Renault. The cad file was created by scanning the old cylinder block. It came out a treat, to the point of actually including old casting marks and flash. The engine worked fine and the car went to the London rally last year. Without this tech the engine would have been a no go scrapper.
Im currently going to school for metallurgical engineering. We do this kind of thing in my courses. One difference is instead of 3d printing the molds, we use styrofoam sculptures. We pack the styrofoam sculptures in sand and pour in the molten metal. The metal vaporizes the styrofoam and the ash rises to the top. Its a little more crude, but proves the concept to us. We also make permanent molds to melt the styrofoam into the proper shape we want so we can have a short turnaround time.
brilliant. I was looking for complete rebuild of an engine block and here these guys made it so simple. Now I know what I need to look for. Big thank you.
The expense is relative to the complexity of the casting. Castings of lesser complexity are not necessarily best suited, but perhaps timing is key. Also with no tooling costs, subsequent design changes are more palatable because they can stay within a targeted budget.
I am very happy to see the vidoe after you give this This video explains the full process of rapid prototyping and casting technology offered by Prometal RCT.
I am so amazed by this. Wow lol 10 years ago and I'm just come across it. Such a clean and clever process. Good for them God bless hope you turn into a monster company.
in the printing the edges of each layer can have a second bonding chemical printed to create an impenetrable ceramic surface to the mold. It would be a little thicker than an eggshell so it would be easy to break away after casting. The ceramic printed surface would allow for the entire mold to be flushed out with water.
yes but in practical terms it is much more corrosion resistant because of the passivisation layer that forms. Except in salty water or when there is an electrolytic cell setup by contact with another metal (eg. iron) in an electrolyte (eg. dirty water).
someone is bound to give credit to god... but solutions are made by man. Only problems are given by nature. Her purpose is to consume life. And we, as living beings, keep looking for solutions that help us survive. And we got so good at the survival game, that we now are optimizing towards comfort and style :D
@J.C. Kohle uh. Yeah, I am showing my education. which is exactly zero in music. Education is a funny thing. It's almost as if you can be a master in one area and not another.
@michaelovitch : no, what they are saying is that 90% of the total product is within 1.5mm tolerance...a machined product can end up outside this range easily (estimating probably around 1cm or more). The 3D printing makes the molds for casting, it doesn't make the end-product directly.
Aluminum is actually very prone to corrosion (aluminum oxide). However, this corrosion actually protects the aluminum from further oxidation. Aluminum oxide corrosion also looks a lot more like aluminum (dull gray to powdery white in color), so it isn't as easy to notice as rusted iron, which turns into the familiar red oxidation.
But to directly answer your question, yes. There are 3D printing machines that can be built as a kit. The medium they generate in is a resin material. I am unsure on the resolution, other than it is within reason for the hobbyist.
@sabriath ok was talking from memory I was alittle wrong, the titanic was within 3 inches of spec . but not over 1000, like the newest big ship , from carnival cruise lies. though was not aware machining threw things off that mutch . thanks for the heads up. maybe machining with coolant allows for nill amounts of warping , never heard of that before though I"m open to learn more things. god bless.
It is older than you are giving credit for. In the last 10 years the cost for printing sand molds has come down drastically, as would any technology which has a solid mechanism.
I dont know about that last sentence, look at the speed in which technology is proceeding. A little while back people would say that invitro, kidney transplants, touchscreens. Heck, we even have some kind of working hologram projectors. At this speed id say that 3D printers will be common technology in manufacturing processes and casting plastic or whatever they do will be substituted by 3D printers
swtnlnly you know that there is no way that you can actually print your own 3d printer right? Its 80% electronics and the another 20% its high spec components or the machine wouldn't print even a pen...
I noticed fire coming out of the fill holes when the molten metal was being poured into on of the fill holes.. Is that from some part of the binding material of the sand blocks being burned off, or??
Imagine being able to recreate some of the greatest engines of all time. An 18 Cylinder engine from a stratofortress or a Bugatti race car or a cast iron engine from a 70 dodge challanger or a 12 or 10 cylinder PT boat engine from Packard........ Isnt humanity greater than that?!!!
Anybody knows what is used to bind the sand so hard here? Liquid glass? Bolts can even be used to tightly hold pieces together - I have seen other video - water or oil to be used in small quantity in the green sand but here the stuff they used is amazing,
There’s a chemical hardening agent that’s added to the sand that only takes about 5 minutes to properly set. At least in my foundry that’s what we use.
I am a mechanic and this is the wave for our future. If do not believe man can fly take a train, take a bus or whatever. Businesses magazines say the it is under rated it will be reach a trillion dollar buisnes in record time.
Quite impressive casting method, however is the sand used for the mold reusable? In the movie itself after the casting, its shown that the mold was broken down.
yup, there's a guy on soliforum that's printing a 1:1 scale DB7 one little square at a time and gluing it up to make a mold for a fiberglass body shell. downloaded classic sports car FTW!
@circusboy90210 : well you heard wrong, and I have no idea where you heard that the titanic was within 3 inches of specifications...plus it was 882 feet long, not "over 1000." Your invalid points are not holding much water. When parts are being machined, the machine (drill/dremmel) is spinning which causes warping in the metal from heat, plus the machines motions are done with gears....this measurement error cannot be avoided. Casting allows closer tolerances.
i think we're quickly moving toward a world where all information is shared freely. look at the explosion of open source software, and even many new musicians freely share their music with the option to donate. with the advent of 3d printers, you can even download the plans to create your own 3d printer, once you have one, it can replicate itself with the addition of a few non-plastic parts. no, i think the crime of the future will be information control.
Sand casting always infuses sand in the cast. Unless a porcelain spray is used. I which case the metal being cast would have a superior finish. With no sand infusion
@sabriath I always heard machined products having tolerances of 10 thousanths of an inch. the titanic was within 3 inches of it's plans and it was over 1000 ft long. that just sounds plain sloppy to me, amazing but still a little sloppy.
I'm not saying it doesn't, but *hard to believe it prints 2 MILLION droplets per second* then again I just noticed this video was uploaded in 2010 and nearly 10 years later I imagine that 2 million is now easily surpassed

What is the mold material
@@salmaemadudin9095 the mould was sand 3d printed. Not exactly sure the precise material, probably sand with sodium silicate.
Thanks🙏
Can I see cast iron block casting in digital printing process
Tu crees que se pueda fundir un motor tomando como copia un motor viejo???

Love that I’m able to learn how processes like this are actually done instead of just reading about it briefly in books. 👏👏👏

This was what we were dreaming about in the eighties 😊

This is probably the most amazing thing I've seen on youtube
Watch more TH-cam.
Amazing!
Damn straight. With the proliferation of the information age, information itself becomes the most valuable commodity.
If only we'd had this technology 40 years ago .......
This is beautiful! Can you talk about what kind of sand and binder you are using?
Thanks!
In Germany ist called Furan Harz Sand and its with 2 components. Acid and haze Mixed into Sand.
U guys made it look so simple ,i am really interested in ur stuff
I just appreciate that they poured molten aluminum with no gloves on.

That's beautiful, I almost cried, my eyes filled with water. How can man create these things! Who taught you?

Supposedly Prometheus gave humans the ability to smelt things.
this is great, but the music is like nails on a chalkboard. Why do we need bells constantly ringing when we are trying to watch the process?
It's your problem 😆

if i understood you can have a iron casted product with an excess of 1.5 mm material compared to a machined product ?

Amazing process ... beautiful
Art and engineering combined in making something beautiful.
7:08 umm, you're in my way man.
Right! So what if they're both carrying molten metal that would be very very nasty...
That is perfect, they 3D printed the reusable mold and then they cast iron to it and make industrial parts with the best strength.
i could watch this all day
@sabriath
ok
Thank you.
Aluminium doesn't rust and has a much better strength to weight ratio. It also looks good and doesn't need much finishing.
40 + year retired foundry man !amazing technology, and all those whiny people on every video go read a book or somithing! if you can read..

That's the wooden engineers out of a job.

Nope
All this awesome tech, and they force the guy to work on a 14" monitor.
Not everything in this world is measured in size, even your dick
Mike Miller don't cry sweetie
LOUD NOISES!!
I love observing comment rage. Please continue.
Woah calm the Tits down.
Its 4 years ago.
And today perhaps the guy working with no monitor.
It was there. You can just see it at 4:49 after it was shaken out. It is rather blocked from a good view though.

molten alloy always spoko
😯😯😯😯😯😒🤨
I kinda want to see them taken out of the sand, how hard was it to remove, finished pieces, etc.
FYI, you can now invest in this company. They are now known as ExOne (Symbol: XONE)
FYI - 3D printing company filed bankruptcy recently after begging it's customers to stop printing 3D printers. LoL Go ahead and lose your money.
swtnlnly
you know that there is no way that you can actually print your own 3d printer right? Its 80% electronics and the another 20% its high spec components or the machine wouldn't print even a pen...
What would something like that engine block cost to make a prototype? I've always dreamed of designing and building my own engine.
Maybe one day we can 3D print our own engines with metal which are already possible.
If I won the lotto, this gear would be in my new workshop, to hell with the Lambo.
I'm with ya! You could get the specs for any old engine block and re-create it!
I noticed fire coming out of the fill holes when the molten metal was being poured into on of the fill holes.. Is that from some part of the binding material of the sand blocks being burned off, or??

Typical cost for sand cores of a 4 cylinder 2 valve pushrod head? Quantity 50-100.
What would be the range of cost per cubic centimetre?
so amazing! but i have a question:why not add a sprue cup or a basin on the top of sprue?(I'm a casting steel engineer in china)

furan binder
There’s a chemical hardening agent that’s added to the sand that only takes about 5 minutes to properly set. At least in my foundry that’s what we use.
Did they make it into section only bcos the machine could print that big or for another important reason?
I just have one word..beautiful..
Hi, I stopped posting
I am a mechanic and this is the wave for our future. If do not believe man can fly take a train, take a bus or whatever.
Businesses magazines say the it is under rated it will be reach a trillion dollar buisnes in record time.
is prometal rct still at market? or gonig on as ExOne?
wow those are marvelous castings
Whats the sand bonded with in the printer? is it something like PVA glue? so it can be desolved easily?
It is silica sand with a furan binder.
Quite impressive casting method, however is the sand used for the mold reusable? In the movie itself after the casting, its shown that the mold was broken down.
Yes its getting crushed, Filterd and need to Cool down at least room Temperatur.
What's the material that the mould is built with?
I wonder what the cost is to print a full block and heads\s package? Withing this rapid prototype sand model/form?
After the cast, the engines require a LOT of machining. And nothing that can be done by hand, may i add.
3d printed sand molds. Awesome there goes my job hopefully they got room on the grind line for me
yup, there's a guy on soliforum that's printing a 1:1 scale DB7 one little square at a time and gluing it up to make a mold for a fiberglass body shell. downloaded classic sports car FTW!
Music was quite nice. What was the tune called?
stop it!
Do you use autocad for programming?
How much the bonder cost?,and were to buy?
Luarrr biasaaa...👍👍 Top👍👍
really woo ... i will buy all that equipment for my factory
Very impressive! :-)

Does any sand wash out of the mold and in to the metal?
There are some videos of that, look for Laser Sintering of stainless steel and titanium.
If the sand molds are 3d printed then why make them in separate peices? I'd think that a one price mold would offer more precision.
i think we're quickly moving toward a world where all information is shared freely. look at the explosion of open source software, and even many new musicians freely share their music with the option to donate. with the advent of 3d printers, you can even download the plans to create your own 3d printer, once you have one, it can replicate itself with the addition of a few non-plastic parts.
no, i think the crime of the future will be information control.
i would like to know if used your precise 3D machine, i can cut the foundry coating cost? Do i need a sealing paste for the mold?
the material used in the printer is plaster?
Excellent texture of casting, but very expensive for production
What is the name of that flash light using
for inspection
what kind of casting sand it is?
is there any tutorial to make this kind of molds?
Quel produits peux t'on utiliser pour monter un moule de moteur résistant à la température (
how much for the mold to cast that engine block ?
How many thousand do you need?

Were can I find you!!!!??
Sir, I want cast bronze statues so I need your advise cost of mchinary in India. Quotation/proforma invoice pl
Perhaps, but how would you make sure all loose sand is removed?
what about the engine desine ? how good
Sand casting always infuses sand in the cast. Unless a porcelain spray is used. I which case the metal being cast would have a superior finish. With no sand infusion
The decks have to be plained and the main bearing seals and the cylinders.
The process looks Expensive
I'm just a normal guy who wants to do a knife with a piece of scrap... this is too much... i need a mustache
Also it has better thermal conductivity.
would a quartz engine work.
How do you make this sand. Can you teach me
de la ptmdre.!!!! gooddd!!
love this music what is it?
This HAD to be invented. HATs off !
@sabriath I always heard machined products having tolerances of 10 thousanths of an inch. the titanic was within 3 inches of it's plans and it was over 1000 ft long. that just sounds plain sloppy to me, amazing but still a little sloppy.
