Rapid Prototyping and Digital Sand Casting Services

[@michaelclark2840]

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.

[@salmaemadudin9095]

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

[@tacha9782]

Tu crees que se pueda fundir un motor tomando como copia un motor viejo???

[@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.

[@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.

[@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.

[@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.

[@y2ksw1]

This was what we were dreaming about in the eighties 😊

[@huxleypig69]

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

[@michaelovitch]

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

[@amyasseektruth8246]

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

[@MrLgmurphysr]

Watch more KZbin.

[@PedroGomez-bd9ro]

Amazing!

[@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.

[@trumanhw]

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

[@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.

[@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.

[@m38calypso]

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

[@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.

[@praballama3310]

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

[@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).

[@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.

[@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.

[@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.

[@michaelovitch]

@sabriath ok Thank you.

[@ahmedlotfy8972]

What would be the range of cost per cubic centimetre?

[@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.

[@williamryder9785]

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

[@patman0250]

i could watch this all day

[@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...

[@Jayneflakes]

Art and engineering combined in making something beautiful.

[@NoferTrunions]

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

[@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??

[@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.

[@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.

[@mustaphaben2921]

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

[@rx0788]

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

[@davidrabin7287]

How much the bonder cost?,and were to buy?

[@johanderuiter9842]

Very impressive, thanks for uploading.

[@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.

[@dekonfrost7]

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

[@MrGoatflakes]

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

[@sujithsparrow9363]

What is the name of that flash light using for inspection

[@siliconvalleyengineer5875]

wow those are marvelous castings

[@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)

[@profesorchris]

molten alloy always spoko

[@مبردواميت]

😯😯😯😯😯😒🤨

[@BABarracus6]

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

[@ToddAndelin]

Amazing process ... beautiful

[@morelkeunmoe394]

Quel produits peux t'on utiliser pour monter un moule de moteur résistant à la température (

[@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.

[@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.

[@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

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

[@Cerdo_asqueroso]

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

[@viniciusdmcicm]

the material used in the printer is plaster?

[@cemkimteknoloji5081]

is prometal rct still at market? or gonig on as ExOne?

[@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.

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?

[@gemsempire5341]

How do you make this sand. Can you teach me

[@automan1223]

how much for the mold to cast that engine block ?

[@dieselscience]

How many thousand do you need?

[@clearz3600]

Music was quite nice. What was the tune called?

[@michaelmorrison7569]

stop it!

[@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.

[@superman6032]

Where can i buy this machine

[@456Tris]

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

[@williamgreene4834]

Nope

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.

FYI - 3D printing company filed bankruptcy recently after begging it's customers to stop printing 3D printers. LoL Go ahead and lose your money.

[@TheGreatZobom]

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...

[@zaidmaqbool2836]

Excellent texture of casting, but very expensive for production

[@sabriath]

@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.

[@websuspect]

The decks have to be plained and the main bearing seals and the cylinders.

[@gdxd7956]

After the cast, the engines require a LOT of machining. And nothing that can be done by hand, may i add.

With what 3D scanner they scanned casted block? Who knows?
