Looks like there was an article about it on ServeTheHome last year too:

Re: Next gen 3D metal printing
#22Good to see! This looks like something I toyed with in 2016, but (as you may expect from my lack of relevant experience and qualifications) all I found were what Edison called "ways to not make a lightbulb". The: > microelectrode array printhead in particular is what I wanted to experiment with, because something like this clearly allows parallelisation of the build process in much the same way photopolymerisation is…
I tried out the multi electrode approach about 15 years ago.
My work was based on the original work of John D. Madden

I can find my paper and post it but keep in mind it was a "undergraduate thesis" and something I spent only a very finite amount of time on.

I mean, we 3d print aerospace engine parts, is this "common sense" logic really true?
The 3D printing they do for aerospace engine parts is certainly very much different from how most metal 3d printing is done. Because the requirements are completely different, and the budgets that aerospace have available to them are insanely much bigger.
I was recently brought in by a friend as a consultant for a traditional machining shop buying a 3d printer, the machine looked like this: https://i.all3dp.com/workers/images/fit=scale-down,w=1200,gr...
Right now you can print aerospace quality parts on hardware that's designed for marine grade parts, which we did by testing them to failure.
The only reason why the price is higher for aerospace is that you need to certify the machines and the environment in which they work and that costs an arm and a leg.

#24I saw a video doing something like awhile ago [1], and I thought the idea of using electroplating made sense, but I know absolutely nothing about chemical engineering or material science. It's interesting to see this idea in action, though with my limited experience with electroplating it seems like it'd be absurdly slow. [1] https://youtu.be/W1d36wbx_yg
This is brilliant. So many problems solved. This person is awesome!

I managed 1μm/minute when electroplating PCBs at home.
Faster and it grows a sponge of copper (entrapped gas I assume).
I would like to know how they did it.

Are you able to recommend any particular low end machines to have a look at in this space?

#27Roselle St (where Fabric8 Labs has their office) is the most innovative street in San Diego. I don't know what it is about that particular street, but a ton of great companies have come out of there.

#28Looks amazing!
Random extremely minor typo spotted, “worforce” instead of “workforce” in the 2nd entry of the “in the press” section.

Low end here starts at $100k, the machines I was looking at were between 500k and 1m with service contracts.

Powder feed:
metal and or ceramic slurry:
Service for the SLS process:
Or wait a bit longer for a good community design release...
Have fun =3
