FIRST EVER 3D Printed COPPER Electrode CUTS Into A286 Stainless | EDM

[@BrainsofFrank]

My mind is completely blown by this process

[@bluustreak6578]

I would never have bet money on the possibility on using a filament printer to make an EDM electrode. This is genuinely surprising.

[@AlexanderNassian]

It's called physics.

[@bluustreak6578]

@@AlexanderNassian Yup. And a fair bit of chemestry

[@AlexanderNassian]

@@bluustreak6578 Not really, it‘s just eroded by the electrical current. But even if it would be, chemistry is also just physics 😉

[@bluustreak6578]

​@@AlexanderNassian Hm, well, to be a little more specific then and explain what my original intention was; The surprising thing was not that EDM works, since it's just physics like you say, and a known procedure. It was more that you can make the electrode with the use of a hobby 3D printer. Surprising also how much copper there was in such a filament. I've never considered the possibility of doing this, alltho it makes perfect sense now that I've seen it of course :) The electrode doesn't care where its metal comes from, as long as it conducts well enough.

This could actually be a big thing in injection molding, especially for industries that do low volume production work or prototyping, or companies that do not want to invest huge amounts of money into expensive copper electrodes for their products.

You can also use the cheaper alternative, graphite, for EDM, we use it at work (injection molding) and it works great.

[@barakobamadubai]

You already in the future, hod bless you guys.

[@allangriffiths8473]

A great idea for roughing electrodes, might need to ensure the main surface face has enough of a layer for wear, as it looked like the electrode broke down and the bulk structure (honeycomb) was visible. What was the overall time from start to finish of the electrode manufacturing?

[@redem.greece]

I only wish to live 50 more years to see where the tech will be!!

[@bobshams7231]

Incredible technology!! I knew you could cut and do basics with wire edm. But a straight plunge like this, first I've seen. Great video!!

[@Grognarthebarb]

This is an old technique pretty sure its older than wire edm. People can still do this in their own home sort of. Lesser results and more development is required but basically they print out of plastic ( you could carve out of wood if you didn't have access to a printer) then paint on a conductive material and after that they copper plate it. (Which can be done for pennies with the battery on your car) Then you have to go much slower at a much lower voltage but do the same thing ( also with a car battery) Look up zurad

[@bobshams7231]

That's awesome, thanks!

[@Grognarthebarb]

[@stevieg2755]

Totally Cool,used to use a Ona sinker but the printed electrode is badass

[@TheTechAdmin]

0:23 This camera angle of you is gorgeous.

[@Shocklingg]

How do you locate the electrode on the holder? The whole point of the holders is to ensure the geometry of the electrode being cut is perfectly related between the CNC and the sinker. That's a lot of bench work for one electrode that could be broken into smaller electrodes and cut on a CNC.

[@mattcyr3342]

In sure they draw the holder in CAD and draw them as an assembly.

[@demovicc]

I think this is just proof of a concept, not real application, for now at least

[@jaredjared8347]

Did you measure the parts to see how close they match the intended size and form? Charles

[@sleepy_143]

That's frickin nuts!

[@runforitman]

thats incredibly cool

[@rasmus1600]

I'd like to know how the dimensions change during washing and sintering. You're removing some material with the washing and i guess shrink the material a bit during sintering. How accurate is the dimensions from from the .STL file to the finished electrode. Isn't there also some loss while using the electrode? As always you're pushing the boundaries of machining.

[@Stasiek_Zabojca]

I bet that Markforged software for 3D printing is taking into a count how much the part is gonna shrink after sintering so it calculates how much larger it has to be and pritns it bigger, so it is exactly on point after sintering. But I'm not sure about accuracy of this, what tolerances are achieveable.

[@rasmus1600]

@@Stasiek_Zabojca Yeah, there might be some software compensation of shrinkage, but that must be hard to control some tolerances. When casting with a 3d printed shape, like a lost wax cast, you usually increase the size of the print by some degree with earlier cast shrinkage measurements.

[@nocare]

@@rasmus1600 its the same way. The part does shrink and warping when shrinking can be an issue just like with casting. Cracking can also be a problem. Shrinkage ranges from like 8%-12% with ceramics up to I think it was 18%-20% for some metals.

[@yakuptopcu3053]

How long is the Overall process time that would be interesting is it faster than cnc milling

[@jvs2926]

Great printer from Markforged.

[@burville100]

Great video guys.. Just a quick question. Which would be cheaper... Mill electrode from solid or 3D print?

[@wildin13]

Depends on electrode.... for example, small "engraving" or logos might be far easier to print and less wasted material but bigger form electrodes used in mould and die manufacturing (which is what sinker EDM is used for mostly) would probably be cheaper and maybe faster to machine. This is not taking into account the cost of raw materials and the fact you can machine graphite electrodes far cheaper and quicker than copper ones.

[@burville100]

@@wildin13 yeah get what you are saying. Been working with making electrodes since around 96 onwards. Always milled. Was wondering on costs involved if they were outsourced for 3d printing. Thanks for the reply 😃

[@wildin13]

Can you 3d print a finishing electrode? What tolerances can it hold? How many runs can it go through?

[@aminehamidouche6118]

what a beauty love it.

[@tashkiira7838]

I'm curious as to how many times that electrode could be reused. The idea of running (for example) 50 or 100 operations with the same electrode would be very useful in cases where the injection mold is subject to corrosion during the injection process, off the top of my head.

[@KWSTASK9]

50 to 100 with the same electrode i don't think its possible and if it is possible it would be a very very very slow operation which i don't think that is something worth showing

[@ferenckraszk4783]

As an EDM technician. You simply cannot. The operation modifies each of the 2 pieces ( the copper and the steel part ) just the copper is a better conductor and it erodes less. We have materials that erodes less like tungsten copper but it's expensive and even with that 50-100 is out of the question. For most of the work I have 1 rough electrode and 1 cleaner electrode. This mostly makes great inside edges. But this is for 1 steel part.

[@davidelias13]

Good video, thanks.

[@danbrit9848]

Did the electrode grow with the cut....it looks like everything that was removed was then added to the copper....

[@wallydeleon2]

WOW!!

[@nofunallowed3382]

Cool that it is possible to print EDM electrodes now. Would it also be possible to print graphite electrodes?

[@Unknown-1407]

I wonder what the tolerance's on the electrode are because i think it must be maschined a little bit smaler to get the tolerances on the part right🤔. Or does it only "burn" on the face and not on the sites of the electrode. I hope you understand what I mean bc I'm not a native englisch speaker (I'm from germany and in my second year of apprenticeship).

[@kraa281]

Do I have to be a CNC magician or a highly trained engineer to understand what you are doing. From my standpoint as an average viewer I am truly amazed at the technical ability that you put forth in not only this video but all of your videos.

[@camerons6028]

Do you guys use any lasers in your shop? My shop uses a 6kw CO2 and a 8KW fiber to do 95% of the profiling (we have a plasma table for the realy big stuff, 40+ feet long) and we are getting a "tube" laser in September to cut and process HSS, round stalk, angle and square stock. If you do any laser work, would be cool to see how you use them.

[@mlab3051]

Thank, this really made it clear.

[@YanivBenAsher]

I wouldn't find it suitable for injection molds since it seems to create rough surfaces that might create undercuts. I wonder what applications it can actually cover?

[@demovicc]

I agree, it does not look accurate enought, but still prety cool

[@MrJzplastic]

I’m curious how you would apply the spark gap in solidworks AND how you center the electrode in the tool holder. I’ve only seen electrodes machined after centered in their erowa holders.

[@wildin13]

We also machine our electrodes set from the reference points of the holders but really EDMers will set electrode offsets at the machine. Meaning it doesn't really matter where the electrode is in relation to the holder. Also the spark gap, a simple push/pull function should work perfectly. We model ours size on size and apply negative stock when machining.

awsome i wuld like to see a hig detail wax resin print coppermoldet and then use as a electrode titans can you do that ?!? :P

[@ROBOROBOROBOROBO]

Newbie question, why do we need copper EDM, we traditionally we machine the copper and why not directly machine the steel? Because it’s more expensive to machine? That the tool dies faster? And can’t this 3d printer make the piece with the cavity directly from steel? So EDM would be eliminated?

[@sumitrustagi6492]

Wow

[@hama3254]

That seems really interesting but the 3D printing makes the progess more complicated for the desing of the electrode. You most likely have some kind of shrinking while sintering the copper after printing, probably some uneven one and you need to account for the spark gap during the EDM itself.

[@Hydrazine1000]

The shrink during sintering is predictable and is taken into account by software that predicts and compensates for it. Same for the spark gap, it's a few mouse clicks away from being compensated for.

[@matteomagni2084]

hi, i use copper electrodes for resistance welding where i work, problem is i have to machine them manually and it's quite boring. how much does a machine like this cost? can be convenient instead of millng them?

For the whole system (3d printer, furnace and wire edm, it would be arouund $500,000USD. The 3d printer and furnace are around $150k and the sink edm is around $350k, plus all your fluids, powdered metals, etc. "boring" isnt expensive.
