i made a METAL 3D-Printer at home! 

How has no one commented on the cat yet? It's the best part

Please don't be afraid to upload longer videos. You are doing great work!

From a fellow engineer, I can tell you how hard it is just to get one of those ideas to work! This is Tony Stark level genius. Absolutely crazy how much innovation there is in this one video.

I’m winning the Ion Thrust War ! Prepare yourselves!

Don't get me wrong the metal printing is extremely cool, but the way you solved the tool swithing problem at 4:10 was honestly so cool to me. True out of the box problem solving!

This idea is going to bring home manufacturing to another level.

Excellent work. One idea for electrical conduction on the build surface. Print with a raft made out of the conductive filament.

I'm an engineer and design everything from phones to car antenna. I use 3d printers a lot and all I can say is wow...well bloody done!

Good job! As a retired jeweler, I'd suggest ending your copper tube with a felt or maybe closed cell foam rubber tip like we use in pen plating. It would require less solution at the point of contact, give you finer control and you wouldn't have to raise the copper pipe higher than your regular print tip, but you would have to replace it more often. Also, you could make a similar output fluid pump using an aquarium air pump, tubing and valves if you wanted to used ready made off the shelf components. I understand your goal of making it yourself though.

For the pump you should look into printing polypropylene, it is semi flexible and is very good for things like living hinges. It is also resistant to most chemicals.

One thing I think you should keep in mind is that not everything has to be 3D printed. As long as you can print the machine that can make the non-printed parts, as well as print the whatever is needed for assembly (such as a robotic arm) then you'll be able to complete your goal. After all, your goal isn't just to create a self-replicating 3D printer, but rather a printer that can be used to to start from scratch. There's nothing saying that you can't 3D print non-3D printing machines to help your 3D printing machines.

you could use shot peening or sandblasting to make the plate rougher. You'll get a nice and even surface and different roughnesses depending on what you shoot at it

In the industry this is done with a pcb of grids of exposed contacts, and acts like an lcd in a resin printer, the contacts only go on for a short amount of time but you can more or less control where the metal gets deposited

Amazing work! This is so so cool. For the conductive build surface issue, why not print a conductive raft/skirt that links all the parts to a single connection? That way you can still print on the PEI surface

I was SO excited watching this video. So many innovative ideas. “Keep up the great work” is not nearly as enthusiastic as I am to see what you'll show for the next developments. Love it!

You are an actual goddamn space wizard. Your combination of talent and sheer unbridled passion is something I wish I had even a tenth of. Keep going, what you're doing is legitimately amazing

Original content is so rare in the 3d printing world! This is awesome. Great work. Really really really great work! We are actually several steps closer to download a car :D

Nobody: SunShine in 10 years: How to make industrial revolution with 1000$

You just got a new follower and discord member. This is the first video I watched from you and I loved the tech and your enthusiasm, it just got a big smile on my face watching this. Please continue gifting us with this creativity, you're brilliant!

This is honestly brilliant in so many ways!!! The timing of this video is also insane, I was just recently trying to design a compliant push latch mechanism and wasn't able to do it. I've searched a LOT and could not find one, you might just be one of the first ones to do it!!! This mechanism could be extremely useful for doing even cheaper versions of the BL touch or the servo probe. You would only require a norma limit switch and the probe would deploy using the printer itself! No need for a servo or solenoid. Genius!!! I love this channel!

I think the easiest solution would be to use a conductive adhesive on the build plate prior to printing. Printing on a metal screen might give good results, but then the screen would be consumable and likely more of a pain to setup and remove after. It's hard to balance good adhesion / conduction with easy removal haha. An easy idea to try would be printing your first layer with small pilot holes, then plate the holes directly to the build plate, that should ensure good conductivity with the part, and if the holes are sized right shouldnt be too hard to pull off either.

THIS IS SO COOL! One of the most innovative things Ive seen in 3d printing in a while. Congrats Sunshine. Happy I found your channel a few months ago. One of my few "bell clicked" channels

so, I have a similar idea, although it was for etching metal, but it works for this as well. If you combine your deposition tube with a suction tube, you can "close the loop" and pull used excess fluid back into a reservoir that can then "refresh" the solution with buffer tanks, stock copper metal, deionized water and electrolytes. This would allow it all to be contained in a single machine. In addition, you could do the reverse and use an EDM power supply and probe to etch/blast away the metal where you don't want it, and now you have an additive and subtractive 3D printer. Just watch out, or you'll have the Knights of the Holy Grail, knocking down your door, looking for a cup.

You and your ideas blow my mind. You make amazing solutions targeted at the masses with fleshed out projects and you do it if your free time. I'm so glad you got sponsored, you deserve it and I'm glad it's not a mobile game.

I love your excitement for the subject matter. I'm dubious about most claims of practical DIY metal -printing and self replicating equipment, but you bring me hope

Incredible. I am excited for the future of 3D printing. If you want to have peristaltic flow without back flow or a second peristaltic stage, you can also put more rollers into a single stage. I normally put 8 rollers into my 3D printed peristaltic pumps.

This is just, wow. Absolutely amazing, such a simple and intuitive concept, yet the smartest thing ive seen in ages. I have no clue how i wasnt subscribed before, but i definitely am now. Excited to try this on my ender 5 plus, ive been wanting to make PCBs at home for a bit now and this will finally make that possible!

Those are truly amazing photons you're sending our way, SunShine! Thank you so much!

super cool. I love the motivation behind what you're doing. I do manual machining and empathize with where you're coming from, it's the whole reason I converted my garage into a machine shop haha. I struggle with the electronics and computer side of CNC though. That's the biggest hurdle that keeps me from jumping more enthusiastically into this whole "self replicating" movement. Awesome vid.

Make the machine create a raft that is normal plastic, conductive on top, and then part printed on that. You'll get bed adhesion, full conductive contact, and it's separable after with ease.

Subbed! Way to think outside the box! Home metal 3D printing is the holy grail of the DIY hobbyist. I've been tracking different attempts at solutions, fusing metal powder and/or sintering seemed to be the only solutions (albeit super expensive/impractical for home use). If this can prove to make useable metal parts, with low difficulty/cost of entry on the setup, then this may be THE home solution for metal printing.

This is an idea I had for a long time and wondered why it hasn't been done before. It seemed like a very simple idea that should have been not *too* difficult to implement. You got there before I got the money and motivation to try it myself.

I've been working on the same thing for two years, except working fully in-liquid, and using copper powder in the liquid to "dope"/speed up deposition. Really cool project, motivating me a lot to get my own moving forward...

That print in place pump is amazing! Such an elegant solution, love it

I LOVE how all the 3d printing people are uniting behind the most outlandish ideas just because we are excited for what might be possible in our hobby! This is what I wish for on youtube: genious ideas, people having fun and coming together. And what you create is batshit crazy in the best way possible, I am all here for it!

You're a madman and a true pioneer of disruptive manufacturing! This will shake up the world soon, keep going!

Genius. If you do a step by step build, the whole community will watch

Wow... This opens up a world of homemade 3D-prints with built-in electronics - without having to add wires/pcb's.

Glad to see you back, what a cool idea it has so many aplications

Really really genius level stuff here, and we can see it in your face and eyes, you really enjoy this! Engineers rock!

Another common electroplating method is to use a metal brush and electrolyte and that way you can essentially brush on the electroplating where you want it, it is similar to this method but the brush probably has a greater surface area. Maybe switching out your large rod for thinner wires would have some benefit.

This is incredible, you've easily earned a subscriber. I cannot wait to see what you do next with these designs

Just found your channel through this video. Just wow, I am so pumped to watch more of your content! I dont have space for a 3D printer at the moment, you can bet I’ll be in the first round of buyers if you make a consumer version of this!

Absolutely impressed with your problem solving skills and ingenuity! Nice!

Super impressive work! Keep it up!

Hey Sunshine , I think I can help with the build plate adhesion. Sandblast the bare metal side. I’m a powder coater and that is the process we use to promote mechanical adhesion on our parts. The powder is plastic and flows in to the profiled surface. Use around 100 grit media at lower psi (probably 40-50 to prevent warping)for a smooth profile you might have to slow down the first layer to promote flow out but maybe not. See if you can find a powder coating shop around you they will do it cheaply. I also cerakote and there is a conductive coating that you maybe able to use to promote longevity of the plate. Keep it up brother.

The compliant switch was a stroke of genius

Amazing work man, keep it up! The fully 3d printed peristaltic pump blowed my mind... Super ingenious! For the adesion problem I would try to take a pei coated plate and then laser etch away the plastic in a pattern of some sort, like a matrix of 1mm circle. The problem with this method could be that the plastic won't flow through the pattern and make contact with the metal plate, so it may be wise to try different pattern to see what works best while also using the thinnest pei coating possible. Hope this helps👍

This was amazing! Thank you for all you do, and thank you for condensing it into bite-size videos for those of us who live busy lives and can't swallow a 30 minute video.

You are genius

Very cool! I've dabbled with dilute PVA glue (old school mirror print surface, the water part evaporates) for bed adhesion for ABS , works pretty well. Maybe it could be doped with graphite or something similar to provide conduction as well.

recently started watching you. wish i had your skill. so many awesome concepts man, love it!

This is incredible, I wish I had a printer I could do this to.

Damn it, why didn't I think of that! Nice video man!

This is genius and has ton of potential for quick prototyping in its current state. Great work super impressive. My mind is flowing with ideas using this to build off of.

I have build one similar to that about a year ago. But really like your solution as well. Though, my problems were the dendrite growth and current densities. I mean, the problems which were not allowing to start printing any large details. Idea of printers being able to print themselves is indeed cool. I've been thinking of this for a while. Btw, I think I found a solution for both of these problems, currently working on it

You dropped an Edison-level bomb of innovation on humanity. As a fellow engineer, absolutely mindblown!! The possibilities are endless, so excited!!

This seems like the first step in creating hobbyist assesable, fully meatal 3d prints.

Congrats, I was experimenting with this in uni, but you got it out first. Mine uses electroplating to create solid metal parts, so it's a bit different to what yours does. It uses ions suspended in an electrolyte jet.

Omg I was thinking about ionic fans on a printer just yesterday. Amazing work, this is really inspriing.

Skynet realised 😮

I can finally print my homemade guns 😍😍

Mr. you are gold. I’m happy to have found you before the other millions of people do. Gives me that special feeling inside. Kind of like this video. Well done sir, thank you for sharing this, million dollar genius of yours for the price of a click!

Man you're kind of underselling yourself and your skills. I opened this video expecting to get my mind blown, but the damn printed pump alone left me speechless. I'd have loved a full video about it alone! You're a genius and a fantastic builder, and I hope the best for you!

Few years ago, I also thought about concept to use galvanising in order to print metal parts. This involved to fill the whole layer with insulation where you don't want metal to build up, and leave the parts where you want metal exposed. This would in theory allow to make a fully metal part, with few limitations and very slowly. And also needed an idea to easily remove all the insulation somehow. And actually your approach is genius. Of course with right materials you can print both conductor and insulator, and also a limiting cup to hold the electrolyte only where needed. The process itself needs some thoughts and adjustments of course, but the concept is very promising, best of luck! By the way, with similar process you can deposit not only copper, but also nickel, iron, zinc, chrome, silver, gold, titanium and a lot more. Each metal requires a special blend of electrolyte and a specific parameters of current, voltage and time. And in galvanisation you are not dissolving the anode, but rather use a solution where needed metal is already dissolved in a good concentration. I suggest you research about galvanisation and try to deposit other metals, should be a great step forward. Also that way you can even create a system where you have an non-reactive anode and just different blends of electrolyte, and you can choose which metal to deposit depending on what you fill the cup with. Also, about problem with print sticking to metal. If the plastic is gripping okay on the surfaces that you electroplated, why not to try electroplate the bed itself on where you are planning to print? Also a better idea right away. Try to tape the buildplate with either copper or aluminium tape, and then galvanise it's surface a bit. You can even lay something under the edges of the tape to create a bowl shape that will hold electrolyte easier. You can even print the bowl perimeter on a pei sheet, and than tape it over and clamp the tape with alligator clip or something. And after printing just remove the tape from the bed and cut away accessives from the print

Its not 3D printing metal. Its electroplating. I would not be wrong if i say cheap tricks to get views...

Why is this the first time I stumble upon this channel youtube?!? Thanks for the video man, subbed & waiting for more.

That's way too brilliant! I knew that it was worth keeping an eye on your channel but I wasn't prepared for THAT

Let's be honest here. Your ideas of grandeur are the farthest thing from what anyone with a 3d printer shares. The process you've created here is amazing. Your videos are overdone with explanations and opinions.

So you're not actually printing metal, you're metal coating prints?

I recently came upon your channel. Some of the things and ideas you show are absolutely amazing. No doubt that you will run into problem after problem. When that happens, grab a beer or go for a walk. The break from your work will really help. Just have the perseverance to keep on going. Please post more ! Thank you for sharing.

Wow you are easily one of my top favorite creators. Your ideas always blow me away and your passion is so inspiring and uplifting. This project is so crazy awesome and i cant wait to see your next iterations! This truly is the start. There have been so many people combining the power of 3D printing and other sciences/fields in the last few years whuch has really started a new manufacturing revolution where we can make things even smaller, lighter, more complex, smarter, simpler, stronger, more convenient, etc. Its truly amazing and i cant wait to see where things go from here!

NOT A METAL 3D-Printer AT ALL! Not particularly useful or well made either. Frankly everything this guy says is idiotic.

Holy shit. You are one of the most innovative and genius people I have ever had the pleasure of watching. Subscribed for sure.

Absolutely brilliant! The pump is amazing, especially the idea of stacking two modules. As you want to avoid non-printable parts, how about a printed extrusion module which could make (endless) lines, belts, tubes, hoses etc.?

These ideas are so genius and I love your concept about “Robots building Robots” to fully make ourselves free to be creative as we so please. Keep this work up, they are an inspiration to myself and many in the IEEE club at Uni.

Awesome work! I can't wait to see where this project goes in the future 😁

Wow! That is great!! Great edit! Gold information! Just wow! No word

Thanks for sharing with us,Slick ! Quite innovative and impressive.Bravo Sir!🌞

love this series, for a possible bed adhesion work-around could you add a "wire" coming from each print using the conductive filament to a specified location then have a secondary probe complete the circuit.

This is amazing. Some genuinely revolutionary aspects to this video. Bravo.

Amazing! You should definitely post more/longer videos! You’re doing super interesting and impressive work and I know people would love to see more, and unfortunately you need to be a good little cog and feed the algorithm if you want to gain subs and views. I genuinely wish you the best and I hope your channel blows up so you can continue to make awesome stuff like this!

This is phenomenal work, great job, so many brilliant ideas, I honestly don't know how you do it.

this is literally the coolest thing i've seen. great work man.

As soon as you went into how it works I knew this was some genius level engineering. Well done.

I LOVE the enthusiasm. You rock. Keep going.

Awesome, amazing, keep up the great work. Finishing up my voron 2.4 now, love to see something that might one day become a mod.

Thanks! Had been considering making an electrochemical deposition printer for a while.

Cool machine man! I'm sure something like that took at least a year to build a model that worked. It took me like 6 months to build a custom wire bender, and still have some fine tuning I need to work on, and that is a pretty well understood process. Your hard work paid off. I'm definitely subscribing, nice work!.

You are brilliant. Your solutions to problems are truly inspiring and great. Really underrated channel. Subscribed and shared \

I used to print on a garolite sheet with copper coating, born for pcb manufacturing. I saw the tip from another channel and it worked fine with proper bed heating, it should offer both adhesion and plenty of conductivity.

Man this is insanely awesome!!!

I am so amazed and impressed by this project!

This is so cool! Good luck!

This is world-changing R&D you're doing! Having done some daydreaming on this problem myself, I can say that with a combination of printed ferrite toroids for mag amps and controlled oxidation of copper layers for rectifiers, you would have all you need for functional (albeit low performance) printed processor cores! There's also ionic rectifiers for somewhat simpler manufacturing (no oxides) at the cost of being bulky and having a liquid component.

this is amazing, to see how electroplating get combined with 3d Printer :D i am inspired even more to do some cool things in the future. Thank You

I love your enthusiasm. Subscribed

From an engineering student interested in additive manufacturing and electroplating, this video really blew my mind. I worked on a 3d printed peristolic pump before and I never even thought to print the whole thing. That alone is truly incredible. I can't wait to see future videos especially with funny tomato man. +1 subscriber for you!!

This is honestly really good improvement

Amazing work! Thank you for your efforts and sharing
