DIY Metal 3D Printer Using A TIG Welder

Dude , take it further . This is super impressive on how far you got without even modifying the original ender 3 by much . I want to see more metal 3d prints like this . Crazy how much work and effort you put into it .

[@klausnielsen1537]

You understate every thing you do. This was a great success to my eyes. The improvements made in the end product are hige considering how this is made with the Bones of an ender 3 and the prior knowledge of automated tig welding of perhaps 3%. You do interesting work in areas normally done only by multi million dollar companies. And excuse to us that it took days!! We love your Work and respect the efforts immensely. Keep it up. Please 🙏

[@gokiburi-chan4255]

[@PhysiczDr]

I would also agree that was better than you think relative to the components and such used. I really believe that with some brain storming, other comments contributing and time that you could get this working with really good results! Great job, keep working on this project! Awesome!

[@TwilightBinder]

the fact you managed to get it to work at all is impressive, the fact that you did a smooth metal print on an Ender 3 is Insane. Please continue looking into this, you are at the doorstep of home Metal printing.

[@robchard19]

Please keep going with this, by no means do i imagine what you are doing is cheap but it seems far more in the reach of the average enthusiast compared to the other metal printing solutions available

[@holon75]

I tig weld, this would be extremely difficult to do. However kinda possible to make it a little neater if pulse welding is possible to do here. Pulse welding lets it cool down a bit so it doesn't just melt away so easily and could potentially hold its shape more.

[@fynnlampe9599]

As someone pursuing a mechanical engineering degree, i can only say that your work is marvellous. I am currently working on my bachelor thesis regarding automating a welding device capable of MIG and TIG for WAAM. Your project has helped me more than 90% of the papers i have read so far. The setup works very well, you could even do research with it. Im thankfull for the aid it gives me and hope you might make a comeback with the project. It is awesome!

[@jacoblind9569]

I think the layer shifting on the x axis is due to the timing belt heating up, expanding, and missing steps. If you replaced it for a lead screw I bet it would help. It might be worth while to rebuild the entire x axis. Replacing the extrusion with mild steel would significantly mitigate the potential for thermal expansion of the aluminum which also might be part of issue. Keep it going, this is getting interesting.

[@nefariousyawn]

Ditto. This machine really seems like it's only missing basic infrastructure to improve rigidity and repeatability, like lead screws. All the hard work is mostly done, it just needs some tidying up and tuning.

[@pstewart5443]

Dude, being an IT Pro I can certainly see your genius. There's like 9 professions involved in this one video. Not to even mention your agility in handling catastrophic issues that come up. I don't know if anyone's told you, but this is the kind of stuff that screams genius-level IQ. I admire and respect your patience and attitude towards issues that crop up. Realistic with just a touch of optimism, and your wiring is phenomenal, worthy of IT Pro praise. I don't know if any IT Pro does cabling properly at their home. I definitely never have, and I've run multi-server labs out of a bedroom/office.

[@RegularOldDan]

Incredibly impressive what you've done! I would definitely be happy to see more. Every non-powder metal 3d printer I've seen before does a very rough shape first and mills it down to the desired shape afterwards. The fact you are getting this much detail without post processing (beyond a wire brushing or the like) is incredible.

[@TheStigma]

Wow! Those results are actually quite stunning. Having the knowhow of all the different fields involved is damn impressive. It seems like the fundamentals work surprisingly well here, so getting nicer looking results is probably mostly a long arduous process of refining the tools and tons of tweaking. I'm definitely subbing for more of this :D

[@Sychius]

I seem to be getting really lucky with seeing your vids right as they go up! Awesome vid, and I love the concept of the metal printer, so I hope you keep it going! That kind of layer shifting is often caused on 3d printers when the head gets caught on something or is moving too much mass and the steppers skip steps. The Ender 3 afaik doesn't have closed-loop steppers so it can't tell when it misses steps and just keeps printing blindly. Idk if you've done anything to counter that, but having closed-loop steppers should solve the problem if that is the issue. Good luck man.

[@Mrstrikerace]

That's just really crazy dude. I'm an engineer and I would have never tried that. To actually use an Ender 3 and bolt a tig gun to it! BIG kuddos dude.

[@sirmiro2]

Wow! This looks promising! The "big" problem seems to be to coarse tooling for too small things. And I guess it's hard to come around. The best would be to get a way smaller welding wire, with everything that follows. The other option sadly is too supersize the printer and do the vase five times larger, as that would give around the wall size expected. It's really fun someone spends energy on this, as I never seems to find time (but had the thougth for years). So please keep this going!

[@artbyrobot1]

[@VerilyRude]

If money is ever an object and you don't already have a Patreon, your work is worthy of being funded by the community. This is great. A couple things that came to mind... 1. A vacuum or at least a purged volume can maybe eliminate or at least reduce your need for argon in the chamber. 2. My hands look like yours and I just had half of a finger removed and nearly died from an infection.

[@D3rron08]

Yay! First comment! Bro I think you are onto something big. Do you think a cooling fan might help it won't blow away argon since u filled d chamber of it? It seems like the print sags from being molten to long. Remember the first circle it was the best, maybe because the plate was cold?

Good improvement! Suggestions: change the motion system to ball screws. Should not be affected (as much) as the belts. Have you coded in some retractions of the wire? Have you tried random z seams? 👌 Keep it up! 👍👍👍👍

[@TopDedCenter]

He mentioned coding in a delay for the wire to stop feeding right before the arc extinguished. But it might not be a good idea to retract the wire since it will likely end up with a ball/bead on the end of the wire that would immediately get stuck or ruin the teflon lining in the wire feed cable.

[@tobiasstaermose]

@@TopDedCenter i guess it will greatly depending on the wire stick out, and how much retraction per pull. It definitely would require testing :)

This looks really promising. How difficult would it be to get the layers smaller? I figure lower amperage, and as small gauge wire as you can manage. Do your tungstens stay good?

[@Spirit532]

I love the attitude of "I think it's shitty, but I'm going to try to make it less shitty", especially when there's steady incremental improvements. It's a refreshing approach, done properly, without the filler crap huge channels tend to do. A few tips: 1 - You're pushing the resolution way too far, and that's why you might not like what you see. Something like this can't print super tiny details, so if it looks wonky, it may be in part because it simply can't not look wonky, even if it was done by hand by a professional TIG "dime stacker". Try scaling the prints up to get a better perspective. 2 - Wire shielding must happen on one end only(i.e. printer -> cable -> box -> outlet), and there should only be one common earth point, not multiple outlets.

[@graealex]

Regarding 1) - the commercially available metal spray printers (i.e, DMG LASERTEC) all add more material than needed and then mill it to dimensions afterwards. So expecting anything more from just a DIY project is an illusion. Only metal powder with selective melting can produce somewhat good results out of the box without any milling. And btw. they're mainly used to repair injection molding tools. If you have a defect, the metal spray can add material where it is missing, and then you can mill and laser it back to spec. For actual "printing", cast metal and milling is the way to go, which can be replicated with a 3D printer as shown by many DIY channels.

[@Ferraday]

[@abushsemahegn2124]

[@educationalpurposesmostly]

keep doing this. These videos are the reason I subscribed. Having a metal printer available is the next step in 3d printing and you could be the one leading it.

[@brainfarth]

I dig the project. I've repurposed a CR-10 for several projects, not limited to extruding peanut butter benchies. On another note, I run a Weldlogic orbital welding lathe at work and rather than have a raw wire liner, it has a mig welding tip to more accurately aim the wire. I hold it back at least 1" from the tip and the gap from tungsten to wire is around .070", where as the wire is below the tungsten. If you have any questions, I program them as well, so hit me up.

[@TheMadManPlace]

"SOMEONE" has probably suggested this before but IF you use a TIG torch you will only have one thing to control and that is the wire feed. Taking the tungsten electrode out of the equation would mean one less moving part and we all know that moving parts tend to have a mind of their own and move where you DO NOT WANT THEM TO GO... BUT whatever you decide to do, PLEASE KEEP DOING IT !!!

SWEET project. As a metalworking tinkerer with a 3D printer, this is awesome content to watch. I think you are doing great work, keep it up.

[@reddtekk]

Awesome work! From my background in welding automation I must say that I know your pain. Getting the wire feed right is a real PITA, and even using ABB robots which are very hardened against noise, I HAVE had noise issues. Here are a couple recommendations that come directly from my experience in making a robot TIG weld in tight spaces with wire feed. If you want to dream, look at Fronius CMT and imagine how nice one of those would be for metal FDM printing. If I had the time to spare and it was MY robot and $30,000 welder, I would have been 3D printing parts using the CMT welder and robot. Just the same, I think that TIG could yield very good results and you have already proven that you are on the right path. First and foremost, it would be very beneficial for you to have the ability to reverse the wire feed rather than letting it ball up. Enabling pulse welding may be of benefit. It will keep the pool tighter and may enable you to build the weld up a bit more without having it sag over. I used a tube for the wire feeder with a hard steel nozzle on it. This allowed me to mount it further from the heat while having good control of wire location and makes it easier to make adjustments. Made the nozzle from drill rod, torched it red and dunked it in water. Hardening it reduces friction, just make sure you smooth your transitions so it doesn't cut into the wire. Use an oversize drill most of the way through and then make an orifice a few thou over wire diameter for the last 30-50 thou. Sand blast inside with fine sand to smooth everything then harden. Regarding noise, you may consider putting your steppers on the outside of the steel case and use drive shafts with insulated couplings. Consider actuating rods and doing the same with limit switches, or perhaps using optical isolators for them. This way you keep your wiring outside and reduce the amount of EMF that you induce on the signal and driving wires. This may be difficult to accomplish using the Ender design, so consider using CoreXY as it will allow external motor mounting and also may make it easier to keep enclosure size as close to envelope size as possible (not a bed slinger) so that you don't need to use any more shield gas than necessary. If sticking to the Ender design you may be able to run a long belt and pulley system to actuate X from a stationary motor, but you will need to re-home X on each layer change or make compensating steps with each Z move. Adding ferrite beads on the entry into the control cabinet can provide additional filtering. Keeping the welding cables on the opposite side of the enclosure from the steppers would provide further noise suppression, and assuring that you keep welding cables perpendicular to control system wires and grounding wires wherever they cross, if this is unavoidable, is also beneficial. Ground your shields to the control cabinet and let them float on the other end. There should be no contact between shields and the welding enclosure. A really cool thing to do would be to have a little spring in the torch in Z, and use scratch starting. This would require a bit of fiddling around with the coding, but could very likely be accomplished. One additional thought would be to use a copper build plate but I'm not sure if the initial bead will adhere sufficiently to the build surface. Perhaps have a steel plug in one or two spots and have your first layer include them. If you build in an enclosed environment, you may be able to use a cooling fan to accelerate weld cooling without oxide problems. OctoPi might simplify your camera issues. It dripfeeds the control and has a built in feature to take a snapshot on every Z move, so you can get rid of the extra limit switch, but I like your idea of moving the torch out of the way before making a Z move so you have a clear view. (Did you do that with your slicer or your firmware?) OctoPi also has a control interface that I really like for running and monitoring the printer remotely. I love your project and it is entails many of the details of a similar project that I would really like to build, once I have a long list of necessary things crossed off. Great work and I am DEFINITELY awaiting the sequel. Liked and subscribed!!

[@Doc_89]
