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.

What is the mold material

[@michaelclark2840]

@@salmaemadudin9095 the mould was sand 3d printed. Not exactly sure the precise material, probably sand with sodium silicate.

[@salmaemadudin9095]

Thanks🙏

[@zaidmaqbool2836]

Can I see cast iron block casting in digital printing process

[@jgreen9381]

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.

[@bobdhitman]

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

[@sanoo47]

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.

[@ToddAndelin]

Amazing process ... beautiful

[@y2ksw1]

This was what we were dreaming about in the eighties 😊

[@johanderuiter9842]

Very impressive, thanks for uploading.

[@praballama3310]

U guys made it look so simple ,i am really interested in ur stuff

[@dannysmith7656]

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.

[@imegatrone]

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.

[@amyasseektruth8246]

This is probably the most amazing thing I've seen on youtube

[@MrLgmurphysr]

Watch more KZbin.

[@PedroGomez-bd9ro]

Amazing!

[@ElizabethGreene]

This is beautiful! Can you talk about what kind of sand and binder you are using? Thanks!

[@gusatvgans9564]

In Germany ist called Furan Harz Sand and its with 2 components. Acid and haze Mixed into Sand.

[@patman0250]

i could watch this all day

[@Jayneflakes]

Art and engineering combined in making something beautiful.

[@huxleypig69]

Damn straight. With the proliferation of the information age, information itself becomes the most valuable commodity.

[@TaylanEkinci]

amazing product

[@ManiacalVDog]

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.

[@siliconvalleyengineer5875]

wow those are marvelous castings

[@m38calypso]

If only we'd had this technology 40 years ago .......

[@NekitaNet]

Very impressive! :-)

[@shajiaxi]

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)

[@RagingCaveman]

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.

[@jhendkap.2340]

3d printed sand molds. Awesome there goes my job hopefully they got room on the grind line for me

[@mikejoslin510]

Very cool process

[@rato004]

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

[@1337fraggzb00N]

Das Ilerminati! :o

[@TomasSab3D]

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

[@GoldenGrenadier]

Supposedly Prometheus gave humans the ability to smelt things.

[@michaelovitch]

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

[@dekonfrost7]

I just have one word..beautiful..

[@MyIvank]

Great video.

[@upcycle]

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??

[@circusboy90210]

@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.

[@stoptenlu3193]

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?

[@trumanhw]

I just appreciate that they poured molten aluminum with no gloves on.

[@Cerdo_asqueroso]

what kind of casting sand it is? is there any tutorial to make this kind of molds?

[@michaelovitch]

@sabriath ok Thank you.

[@NiteReepa]

It might just be me, but I think there is something very beautiful about metal being poured.

[@xNickBW]

ohh my wow!

[@azizhuthale]

really woo ... i will buy all that equipment for my factory

[@viniciusdmcicm]

the material used in the printer is plaster?

[@ManiacalVDog]

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.

[@AlehandrosArhangelos]

That is perfect, they 3D printed the reusable mold and then they cast iron to it and make industrial parts with the best strength.

[@priscilamaia5840]

Muito manero parabens

[@zzanzak]

love this music what is it?

[@Psychlist1972]

7:08 umm, you're in my way man.

[@blogobre]

Right! So what if they're both carrying molten metal that would be very very nasty...

[@ahmedlotfy8972]

What would be the range of cost per cubic centimetre?

[@hussein_iraqibagdal1898]

Thank you very much

[@privatedata665]

Way awesome ....

[@v12tommy]

What would something like that engine block cost to make a prototype? I've always dreamed of designing and building my own engine.

[@unclenickynvp5074]

Maybe one day we can 3D print our own engines with metal which are already possible.

[@BABarracus6]

Does any sand wash out of the mold and in to the metal?

[@ManiacalVDog]

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.

[@MrGoatflakes]

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).

[@AwesomeCreationOfficial]

Very nice

[@edgarpari2906]

de la ptmdre.!!!! gooddd!!

[@dekonfrost7]

I wonder what the cost is to print a full block and heads\s package? Withing this rapid prototype sand model/form?

[@MarceloPereira-vl3gh]

Lindo trabalho parabéns 😊

[@rx0788]

Did they make it into section only bcos the machine could print that big or for another important reason?

[@Budivedder]

Nice machine

[@CTimmerman]

Perhaps, but how would you make sure all loose sand is removed?

[@Gevehi]

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.

[@gusatvgans9564]

Yes its getting crushed, Filterd and need to Cool down at least room Temperatur.

[@sabriath]

@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.

[@Psychlist1972]

All this awesome tech, and they force the guy to work on a 14" monitor.

[@inbuckswetrust7357]

Not everything in this world is measured in size, even your dick

[@inbuckswetrust7357]

Mike Miller don't cry sweetie

[@JohnJones1987]

LOUD NOISES!!

[@MuffinMan0521]

I love observing comment rage. Please continue.

[@dwinhoval]

Woah calm the Tits down. Its 4 years ago. And today perhaps the guy working with no monitor.

[@camarobo9244]

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?

[@shivamkale6783]

It's your problem 😆

[@camarobo9244]

@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.

[@MD_Builds]

Whats the sand bonded with in the printer? is it something like PVA glue? so it can be desolved easily?

[@ManiacalVDog]

It is silica sand with a furan binder.

[@sujithsparrow9363]

What is the name of that flash light using for inspection

[@superman6032]

Where can i buy this machine

[@lvd2001]

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,

[@ManiacalVDog]

furan binder

[@Itsbigpitch]

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.

[@walterbunn280]

This pretty interesting.

[@ManiacalVDog]

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.

[@fakiirification]

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!

[@micropro3002]

vary nice...

[@dwightcheck]

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..

Typical cost for sand cores of a 4 cylinder 2 valve pushrod head? Quantity 50-100.

[@profesorchris]

molten alloy always spoko

[@user-pm7qo8vv4z]

😯😯😯😯😯😒🤨

[@williamryder9785]

I kinda want to see them taken out of the sand, how hard was it to remove, finished pieces, etc.

[@mastain8227]

Luarrr biasaaa...👍👍 Top👍👍

[@i_am_ironman3380]

Very interesting

[@jeffbrent]

The process looks Expensive

[@hambatuhan5751]

Do you use autocad for programming?

[@mustaphaben2921]

What's the material that the mould is built with?

[@kevkeelan5106]

Very very clever.

[@cronos1.2_sqrt5.2]

This HAD to be invented. HATs off !

[@user-ns6jq7xr7f]

Матрицу из какого материала распечатывают?

[@ManiacalVDog]

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.

[@MrGoatflakes]

Aluminium doesn't rust and has a much better strength to weight ratio. It also looks good and doesn't need much finishing.

[@jesuschil3491]

i liked the music

How do you make this sand. Can you teach me

[@sadlonelylad]

what about the engine desine ? how good
