Max assumed: I'm assuming you have a copy on your bookshelf LOL

My Multiwire boards are way too big for my bookshelves.  They're in "long-term storage".

Oh, were you talking about Bebop?  My bad.  Gee, if I can get a used copy for $0.01 I should check it out!  Is Multiwire in the 2nd edition as well (used copies available for $4)?  What's the difference between editions, seeing as how Boolean logic itself hasn't changed much in our lifetimes?

Ok, I'll bite.  How come it couldn't be 2 layers?   Traces on both sides with via holes drilled. Or if no drill capabilities then just via pads and you drill the vias, no problem.  Then all you have to do is put buss wire through the via holes and solder both sides.  OTOH the web site looks shady or better yet to be wishful thinking hoping for investors. Personally I like the type of machine that mills off the copper you don't want just leaving the traces.

@betajet: Who remembers Multiwire?

I do! I do! (said Max, excitedly :-)

We used it for prototyping boards backin the mid 1980s. It was actually a really good technology (for the edge-rates and clocjk frequencies of the time).

I had a section on this in the my book Bebop to the Boolean Boogie (Edition 1) -- checking on Amazon I see you can get used copies for $0.01 LOL -- but as far as I know no one is really using it anymore, so that topic was dropped in the current Bebop to the Boolean Boogie (Edition 3).

I'm assuming you have a copy on your bookshelf LOL

Maybe they're working on patents and don't want to divulge anything they might want to patent.  When they do their search, they'll find a bunch of expired Ariel Electronics patents :-)

From the photos, the ink looks a lot like Chemtronics CircuitWorks conductive ink: https://www.chemtronics.com/p-693-circuitworks-conductive-pen.aspx

Maybe they "print" blobs of insulation to allow cross-overs.  That's what Ariel Electronics did (see below).  This gets unwieldy with more than two layers, hence the limit.  If your lines are narrow enough you can get a heck of a lot onto a single layer with crossovers.  Who remembers Multiwire?

If you've never heard of Ariel Electronics, here's a repeat of my EE Times comment from Oct 2013:
Around 1990 there was a promising attempt to do this by Ariel Electronics (California), which created a gadget called the Circuit Writer which extruded conductive plastic wires onto a substrate.  I actually visited Ariel and saw a Circuit Writer working.  I don't think the technology got anywhere, but maybe it was just ahead of its time and with newer 3D extrusions this could be done practically.  For more info, Google "ariel electronics circuit writer".

@dt_heyden: I'll bet they mean double sided and have not addressed vias, meaning it is really a device for printing single sided boards.

It's a bit sad when they can't convey exactly what it is that they are doing/offering in a form the rest of us can understand.

This is a cool technology.

I wonder thought whether when alll is said and done it(or something) will end at the distributor , which will let you rapidly order circuits, with a wide selection of components ,with lead times of 24 hours ?  sure it would cost a bit more, but just the wide variety of components would justify this for many proefssional engineers , no ?

I'll bet they mean double sided and have not addressed vias, meaning it is really a device for printing single sided boards.  The detailed photo under Pads and Traces indicate a layout which avoids traces crossing over (facilitated by multiple layers on one side).  This would still be useful for limted applications.

The resistivity quoted indicate it is more on par with performance of carbon inks than metal.

A few days ago there was a comment thread associated with a blog about forgetting things (unfortunately, I can't recall which blog it was LOL).

The thing is that I don't remember seeing the Voltera website before, but when I tried to submit my email to be apprised of future developments, the system told me I was already registered.

So either I registered only last week and my memory is way worse than I thought it was -- or I registered yonks and yonks ago (sufficient for me to forget) and nothing has happened to thsi desktop PCB printer since that time. Either way is problamatic LOL
