[@fitzgeraldmistral97]

Been waiting for that technology for quite some time..

[@DrEnginerd1]

We'll start seeing plastic substrate boards that can be printed on by this ink, then custom pcb printers. This is exactly what I've been waiting for! So excited for this to come to market

[@ScottLahteine]

The next thing to include is a conductive glue similar to superglue or modeling cement, which would work just as well for attaching surface mount components as it would for through-hole components, because it can form blobs. I'd be curious to know how the surface mounts were placed on the prototype board that was shown if there is no such glue, or whether they were cemented and baked....

[@semphony100]

This is simply huge !!!!!! as he said I instantly think of tons upon tons of applications. circuit design on paper for kids learning board design for starter. Touch customized flexible notebooks with circuit designs of all sorts making cool stuff, throw in a OLED flex screen and the sky is the limit. even add this in some way to a 3D printer and you get a 3D printed circuit board with multiple layer design. Tron suits with real circuits printed on cloth and led lights. electronic light switch buttons drawn on the walls this is just crazy !!!!!

[@aimless3827]

Its been 6 years and you still can't find that ink.

[@elrickking9293]

you can do this with silver paste, glossy paper a laser printer and a hot air station.

[@TechnomancerTheWise]

Not for consumers

[@JonathanKayne]

so they took the conductive ink and put it in a printer cartridge... I thought of doing that design a while back, but im happy to see someone acually do something with it! I sooo want some!

[@Geeksmithing]

So glad he clarified it was Tokyo, JAPAN.

[@EpicAwesomeWin87]

I thought he meant Tokyo, France

Excellent Idea...

[@fss1704]

a origami antenna

[@fss1704]

with solar cells printed

[@TheFrozenMister]

Awesome! Can't wait to see this happen since it's surely way easier than etching.

[@graphicsgod]

How could anyone dislike this you monster!!

[@yishujia186]

This is a piece of good news to hobbyists. Please integrate it to a 3d printer so that we can print the circuit on the inner walls of 3d printed parts. This will save a lot of effort and make things compact.

[@ukpoetry]

Really exiting! We just need printable ICs

[@oliverjunge8671]

A question I would have liked to hear would have been how the resistance compares to etched PCBs and compared to silver based conductive paint which is available for decades. High resistance is what usually makes these paints impractical for most circuits.

[@charlesmarseille123]

this is the question

[@Neueregel]

Very cool ! I hope it gets implemented in clothes in the future !!

[@JoeGP]

something similar is being used in cheap keyboards for years (printed circuits i mean) 3 layers actually the only new thing is the conductive paint cartridge, still cool though

[@JeffConnelly]

Weighted components with large contact areas would be best for quick prototyping with this. Like a heavy, blown up version of SMD components.

[@omsingharjit]

I think its low temp metal alloy like indium gallium or Ag compound

[@landlockedviking]

how about spray paintable house wiring!

[@ElectronFunCom]

You would pay a fortune for such wiring.

[@Audivision4U]

The waste of copper is terrible

[@TylrVncnt]

Vintage e Independente - ok then what else could support the current needed for house wiring..? Do you know how *wasteful* you’d need to be (in terms of the massssive amount of this stuff you’d need to use) to get the same results as pure copper...??

[@gavincurtis]

Awesome. About time.... or at least make a drop in conductive ink cartridge to convert any printer. But the other alternative where you laser print your pattern on gloss paper/film and then apply conductive silver ink which bonds to the carbon toner works quite well in the meantime. Be neat if you could take your gerber file to Kinko's.....

[@toddmckenney4511]

What I want to know is could you electroplate this to produce traces for multilayer circuit board combined with a resist that could really open up custom electronics.

[@omsingharjit]

You did not talked about its ink and its material

[@RobPaige]

I'm curious how they ensure good contact between the pads and the devices placed upon them. Yes, I saw the taped LED but the other circuit board didn't look taped.

[@josephKEOarthur]

awesome! wearable art! print fabric circuit boards.. (just increase the viscosity of the ink on a semi permeable fabric). OMG My TRON suit will be a reality!!!

[@adriandeveraaa]

Yikes. I was going to buy an ink kit but $270 for 50ml? Wow. I buy it for $50-80 but 270. Market isnt there.

[@kevinz4396]

Buy & sell circuits on ebay/facebook

Appreciate very nice congrats

[@codebeat4192]

What is the resistance of a track?

[@gasoke]

Is that silver base ink? & What is suitable material for printing.

[@sanketbandal8915]

Hello sir, I am a student currently working on conductive ink project basically silver. Can u please help me with it. Actually on what point i can work on. I went through internet still didn't find much of information. Can u please help me with the problems currently persists for silver and also the ingredients used...

[@imir8ati]

Wow real cool, thank you for your work

[@rakka1dude184]

orange leds are the brightest!!! :D

[@jamesholton1291]

In the words of the internet "Shut up and take my money!!!!"

[@jarrodhroberson]

so how do you more permanently connect parts to the printed circuits? the tape example isn't cutting for me at this point. This is one important piece of information that should not have been left out of this video!

[@adecker720]

Search for "conductive glue." There are many kinds which are more or less permanent.

[@Dancopymus]

Very interesting! How are the components fixed on the paper and how much amperage do the tracks support? Thank you

[@MLGRecognize]

Can you solder on it?

[@kylek29]

The article says yes, but not reliably.

[@octapc]

You can look at alternative solder including silver solder for low temp soldering.

[@billweinberg5831]

are you interested in a solution to do so?

[@jayfulf]

What amperage can you put through this? I didn't watch the full video so maybe this was already answered.

[@buzzwerd8093]

How much is the printer? And print cartridge, and pages printed from it? Will the head clog if not used in days or weeks? Is the pen also the 'solder gun'?

[@miguelfernandosilvacastron3279]

Do you already know your question? If so, please tell me

[@lancehuttsell3878]

i wonder if this can be layered to conduct higher amperage or voltage...

[@ma4music]

where I can buy this .. any link plz ...

[@johnhopkins6260]

would be nice to know brands/names to search for electrical specs (i.e. Ampacity, or equivalent wire gauge)

[@sincerelyyours7538]

Looks promising, but I'm afraid I don't fully understanding the technology. You say it works with an inkjet printer? My guess is that it will require not just any inkjet printer but one with special print heads containing special conductive inks and a straight-line paper path. Can you print onto FR4 boards directly or can it only print onto flexible sheets like thick photo paper or acetate? Would you then paste the printed sheet onto a rigid board? What about the soldering and heat-sinking of ICs and transistors? Can the Arduino circuit shown in the video be populated and shown in action? How durable would the finished product be? In my admittedly low-volume production case, my 20 year old HP Deskjet printer probably won't handle the electro-ink printing chores so that will require my purchasing a new printer - something I have been trying to avoid. I keep my old HP because it prints regular ink onto translucent sheets just fine and I can then expose the images using UV light onto photo-sensitive boards, a simple and well-proven process. The UV/Inkjet method also avoids my having to buy a laser printer and laminator just to do toner transfers. However, this new approach appears to eliminate the Ferric Chloride etching steps, always a bonus for me (the fewer chemicals in my house the better), so perhaps it is worth considering for that quality alone.

[@miguelfernandosilvacastron3279]

Can anyone point the place where I could buy the printer and the ink?

[@layakaaproductions5956]

What type of paper and ink is being used here .Pls tell me the name .So that I can but it.

[@John_Smith__]

Totally Awsome !!!

[@AudioTherapy0]

This technology is used in keyboards

[@Raketbaever]

This....

[@EuanTodd]

its abit more/less technical than that they treat the plastic with a special coating of tiny specs of metal where the circuit is going and then they can electroplate it

[@fss1704]

+euan todd fuck that, why can't we use the different colors in the printer to reduce the copper? i was thinking about making a magnesium battery on the paper to reduce copper, you just have to create a battery for the displacement of copper from copper sulfate, so you can invert the color and change it to the color your print uses and print with magnesium in blank areas to reduce the copper. you can let it dry and print the sheet again a few times if needed, the copper will reduce electrochemicaly, oxidizing the magnesium, and the paper will form a copper circuit. You can even print these circuits and overcharge them with magnesium then slowly submerge or spray the circuit with copper sulfate. As an end product we have magnesium sulfate and copper, that's known as chemical reduction

[@chetniksrb333]

[@Mentorcase]

Conductive pens have been around for years for circuit repair work. google it.

[@EuanTodd]

if you can get the ink cheap and you get one of those empty refillable cartridges can you fill the black ink side with the ink and print it like that??????? just a thought

[@mitropoulosilias]

i thought the same...

wait if the makey makey can use a regular pencil, cant we just make a simple circuit using a regular graphite pencil and regular pencil?

[@charlesmarseille123]

Yes you certainly can, the electrical caracteristics of graphite are different tho than this ink. But it sure works!

[@therestorationofdrwho1865]

Give me one of those pens right now.

how much power supply can that printed circuit can take?? reply ASAP please

[@jakehughes604]

This is actually not that technicaly advanced. It may be simple and easy , but has already been done, it just hasn't been put up for public sale and was still being improoved

[@skynet1537]

Printable WiFi Antenna FTW!!!!!!!

[@VenkateshksDr]

Check out Robert Murray-Smith. He gives a few methods of making conductive inks at home.

[@piglet2548]

It's just liquid metal.

[@artbyrobot1]

No it is silver powder mixed with glue. You can make your own

[@NoorquackerInd]

I highly protest to this! Why inkjet? I have one that always jams and a black and white old laser printer! Why would you use inkjet if you *ever* want to make PCBs?

[@elecelec4982]

its nothing new, its been used on the dashboard of cars for many years. and can be used only for single layer boards may be fun for the hobbyist but definitely at this time not for the industrial market

[@KTFist]

even thinner phones and laptops

[@veluvelusamy3517]

t want this ink

[@ElectronFunCom]

It's a great idea, but the inks are going to be quite expensive. This invention is definitely not for hobbyists.

[@springplus300]

Isn't that kind of debatable? The hobbyist is, in a sense, likely to fork out a little extra for the chance to make a unique result, whereas expensive processes make less sense in mass production. Of course, on the other hand, mass production would eventually lead to lower prices, simply as a result of demand. It's kind of a double edge.

[@NathanFrith]

Agree with Jonas on this one. 3D printing is a perfect example of this.

[@springplus300]

***** Was about to mention that myself. Furthermore, the mere fact that it's designed for regular, completely common inkjet printers should make it pretty obvious that it's aimed at the DIY community. It's not a coincidence that Make takes an interest in this stuff. Flexible electronics haven't been a problem in the industry, but if you are a maker or hobbyist, stuff like this has been pretty hard to do. And even conventional etching still leaves you with the problem of having to be sure you got the circuit right the first time around, unless you want to spend a LONG time on trial and error. What this allows you to do is, much like 3D printing, to prototype, or make a custom project very quickly - with lots of room for trial and error.

[@DustinRogersinMO]

You can make conductive ink by mixing in graphite powder. I've also seen conductive glues made the same way. The trick is getting it into the inkjet cartridge. LOL

[@springplus300]

Refillable cartridges are easy to come by for basically all common brands of printer. I'd be more concerned about clogging!

[@art1muz13]

SOOOOOOOO, SOMEONE COULD WALK AROUND WITH A PIECE OF PAPER......FOLD IT AND BOOM!!???

[@ricardoamendoeira3800]

How is that any more dangerous than someone with a switch, button, or something like that?

[@art1muz13]

'CUZ WITH THIS NEW TECH IT'S ONLY PAPER AND A BUTTON CELL BATTERY .THE PAPER COULD HAVE THAT SCHEMATIC WRITTEN TO MAKE A "CLOSED - CIRCUIT FOR A REMOTE CONTROL DEVICE. SO WHAT 'S ON THE OTHER END, WHAT COULD POSSIBLY BE REMOTELY CONTROLLED? AND WHOM OF THE TWO PEOPLE WOULD RAISE MORE SUSPICION? THE GUY WITH THE SWITCH AND BATTERY OR THE GUY WITH JUST A "PIECE OF PAPER? LET'S SAY AT AN AIRPORT. REMEMBER IF YOU ABOUT CIRCUITS ALL YOU NEED IS SOME TYPE OF TECHNOLOGY TO CLOSE A CIRCUIT TO DO DAMAGE, JUST SAYIN.

[@adecker720]

Artemus Rodricq STOP SHOUTING. There are any number of devices we use every day (and carry around at airports, etc.) that have circuits, switches, batteries, radios, etc. But mostly STOP SHOUTING.

[@ricardoamendoeira3800]

Artemus Rodricq I think the guy trying to awkwardly fold a piece of paper inside his pocket looks more suspicious than the guy that flips a small switch inside his pocket but that's just me I guess.

[@art1muz13]
