[QUOTE=Deathtrooper2;47431652]I think you fucked up on the link...[/QUOTE] wow cool no shit?
I was excited then saw it was just a model A "functioning" model but still, just a model powered by electricity. Pretty cool still!
This is really cool. I can see this being used for teaching people about how engines work and such.
[QUOTE=Tmaxx;47431657]wow cool no shit?[/QUOTE] just giving you shit
I dont think you could actually 3D print an engine just due to the sheer fact it would melt right?
[QUOTE=Bomber9900;47431895]I dont think you could actually 3D print an engine just due to the sheer fact it would melt right?[/QUOTE] You can 3D print with metal but the strength of 3D printed metal is always going to be subpar and the engine would have to be considerably heavier and undertuned to be any useable.
I'd could be possible to do a really low compression engine. It wouldn't be hard to do an air cooled one with thick cylinder walls. The only hard part would be cleaning oil passages, and grinding bearing surfaces smooth, and boring the cylinder and smoothing the piston.

[QUOTE=dai;47432319]so what you're saying is the 3D printing would be moot because you'd end up needing to mill it all anyways[/QUOTE] Well yeah, but it would be a step in the right direction of functional items being printed. It wouldn't be cheap or fast like cast or machining, but it would be using new tech in a new way. [editline]31st March 2015[/editline] Imagine being a future gearhead. Soon we'll be able to make and print whole, functional transmissions and engines. Just like when paper printers came out, it will take a while for the resolution and price to go down enough but once it does, it will be a thing. I feel we're already close.
Don't they already print aircraft parts and rocket-nozzles? I can see it being adapted to hobby-gearheads no problem.
[QUOTE=ewitwins;47433944]Don't they already print aircraft parts and rocket-nozzles? I can see it being adapted to hobby-gearheads no problem.[/QUOTE] As surprising it may seem, rocket nozzle requires far less structural strength than the critical engine or god forbid gearbox parts. Furthermore you want some serious mileage out of your internal combustion engine whereas the rocket nozzle is something that's under stress for maximally tens of minutes at a time and is often considered throw away anyway. And I can assure you that the printer they made that on is anything but affordable for hobby gearheads and that's not something that will change easily.
I can't wait until we can start printing metal parts.
[QUOTE=ultra_bright;47435198]I can't wait until we can start printing metal parts.[/QUOTE] You can wait for quite a while, really.
[QUOTE=dai;47432319]so what you're saying is the 3D printing would be moot because you'd end up needing to mill it all anyways[/QUOTE] well, to be honest, even if it's absolute shit, it's very much good research a 3d printed engine perfectly scale models a fully milled one without having to spend assloads of money
[QUOTE=Awesomecaek;47435297]You can wait for quite a while, really.[/QUOTE] Found the pessimist.
[QUOTE=ultra_bright;47435198]I can't wait until we can start printing metal parts.[/QUOTE] We can do that already (Known as laser sintering), but its reserved for corporations/research labs due to the cost. I.e. Oak Ridge Nat'l Lab in TN has a titanium laser sintering printer, using titanium oxide powder as a input.

[QUOTE=Awesomecaek;47431945]You can 3D print with metal but the strength of 3D printed metal is always going to be subpar and the engine would have to be considerably heavier and undertuned to be any useable.[/QUOTE] Or a steam engine. The hottest part of a steam engine is gonna be within ten degrees or so of the steam itself, and few model steam engines use superheated steam, so it's entirely possible to 3d print a perfectly functional steam engine.
I would totally take a 3D-printed engine-block, especially if they're modified versions of classic engines.
