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
@michaelclark28402 жыл бұрын
@@salmaemadudin9095 the mould was sand 3d printed. Not exactly sure the precise material, probably sand with sodium silicate.

@jgreen938110 жыл бұрын
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.

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.

@RagingCaveman10 жыл бұрын
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).

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.

@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.
