When I get my printer, I’m going to print a whole new earth.
Just in case...

That biomimetic architecture is a hallmark of generative designVery cool!

a printed copper thrust chamber successfully completed a series of hotfire tests... That info leads to more questions. I believe copper melts well below rocket exhaust temperatures. The thrust chamber, whatever they are made of now, gets red hot. Perhaps the copper is not the exposed-to-exhaust layer.

I’d be happy printing a capstone for one little patch of earth in DC...

Gets even more bizarre, at least to me.
Met a guy last week who works for a company that are using a patients cells to 3-D print lungs for transplant!!!
I can’t conceptualize this!
I need to read “3-D printing for Dummies.”

Yup, Chapter 1 - Printing Organs. Wait’ll they start printing brains. I think I need a new one of those!

Couldn’t get the info to download from your post.
Could you please repost an another internet page or format??
I would like a new brain too and a body that doesn’t ache and can stay up to midnight and get up at 5.
Don’t think “Super Beets” is gonna get me there. LOL.
I find this stuff fascinating.

No. I was too shocked.
Google 3-D organs.
Lordy, This seems impossible. Need to read.

One can create the engine such that the cold fuel or oxidizer cools the engine on it’s way to the thrust chamber.

I'll need one off a Saturn V to get my import up to speed.
To the Moon!

Therefore, temperatures used in rockets are very often far higher than the melting point of the nozzle and combustion chamber materials (~1,200 K for copper). Two exceptions are graphite and tungsten, although both are subject to oxidation if not protected. Indeed, many construction materials can make perfectly acceptable propellants in their own right. It is important that these materials be prevented from combusting, melting or vaporising to the point of failure.
This is sometimes somewhat facetiously termed an "engine-rich exhaust". Materials technology could potentially place an upper limit on the exhaust temperature of chemical rockets.
Many fun details here:

Copy and paste. If that doesn’t work, just search Google for ‘Printing Organs’, which from your post #12, looks like you’ve already essentially done that search. Yeah, the future looks like it’s going to be mind-blowingly awesome!
To: DannyTN
Cool. What are you going to call it?
