No post processing with a huge asterisk. You need to take the part out of the cake and also remove the powder out of those tiny channels. That takes a comparable time relative to the removal of support. It does not come like that out of the printer.
@@Jokemeister1 Yea but surely flange faces will need to be machined so some machining is also required. Certainly not yuking the yum here but I agree with @lucianoag999, using limited post processing would be more accurate. It's frustrating when salse guys feel they need to over hype something when it not required. This is amazing tech let it stand on its own.
well the input and output ports clearly need post processing still, but regardless, extremely cool. I find it bit strange that the "no post processing" is such a big deal, i mean it already has geometry you could not do with conventional means, what adding few machine hours to do few threads and interfaces by milling after paying for 300+h of sintering + all the post stuff related to that ?
that will never happen. It is made from aluminum so it cannot work. It would just melt instantly. Also it was generated by Ai, another guarantee it wont work. It is just a nice model to show case
this one will never run as it is made out of aluminum, which means it would melt immediately. Also it was Ai generated which guarantees that it will not actually work. It is just a nice show case.
A lot of computer phobic "engineers?" here are suffering from the "that's not the way we've always done it" syndrome. Computer controlled and designed additive manufacturing is well on its way to revolutionizing and replacing the ways and speed things are built and how much they cost. They need to learn the new way or at least not get in the way.😉
He said 'uses liquid oxygen as a propellant'. That is exactly accurate. It uses liquid oxygen as an oxidizer and an unspecified fuel, but both are indeed propellants.
@@TroyRubert Most of the mass flow rate of chemical rockets comes from the oxidizer. Again, there is both fuel and oxidizer but since both contribute to the mass flow rate and therefore thrust of the engine, they are both are considered propellant. Look up propellant mass for any rocket. It is ALWAYS fuel mass plus oxidizer mass. The SpaceX Super Heavy booster holds 6,000,000 lbs of liquid oxygen and 1,500,000 lbs of liquid methane. Total propellant mass is 7,500,000 lbs.
Yes, this is clearly a finished part. Do you think we're stupid and not aerospace engineers? Okay never mind the missing goesinta and goesoutta holes, tell us about the number of hours this or an identical engine ran, and at what performance levels - ie; chamber pressure, throat size or thrust, throat temperature, chamber wall temperature, that kind of thing. THAT is how you impress your actual market and not just advertisers. If it hasn't run, it isn't a rocket engine, it's modern art. And if you don't respond, we'll know, won't we?

Pretty sure they're referring to machining after the additive process is complete.

Impresive.
what a stunning piece of engineering and manufacturing... would LOVE to see it do a full burn
that will never happen. It is made from aluminum so it cannot work. It would just melt instantly. Also it was generated by Ai, another guarantee it wont work. It is just a nice model to show case
They already are 3D printing certain elements of their raptor engines! Pretty dang awesome!!
@@ikew3150 yep, using printed inconel
this one will never run as it is made out of aluminum, which means it would melt immediately. Also it was Ai generated which guarantees that it will not actually work. It is just a nice show case.
@@johgude5045Look at NASA aluminium RAMFIRE nozzle. Same as here, the internal coolant keeps it from melting.
Damn i love your content so much. I am in this mode to know 3D metal prints for rockets. Thank you for make it.

But LOX is an oxidizer
They make rocket oxidiser tanks out of aluminum.
@ and steel. Saying lox was the propellant when its the oxidizer is what I'm pointing out.
He said 'uses liquid oxygen as a propellant'. That is exactly accurate. It uses liquid oxygen as an oxidizer and an unspecified fuel, but both are indeed propellants.
@ not accurate. RP-1 or Ch4 or LH2 would be the fuel. Again LOX would be the oxidizer for the propellant.

Cameo from Stephanie at 0:50, thought we wouldn't notice
hmmm I wonder... what's the melting temperature of aluminum? And how hot does LOX + methane, hydrogen, kerosene? burn at?
Let see if SpaceX starts using this or not.
SpaceX prints its engines on Velo3D
Have you seen the iteration in the raptor engine? V3 is very much like this
Liquid oxygen as the propellant......??
If anyone watching this and hiring for meral additive manufacturing engineer. Please contact .

He meant finished like it's all done and dusted and ready for the display case finished, not for in use finished lmao
