[@FoX_Corp]

What kind of electrolyte do you use? What is its composition?

[@enriquemoreno8836]

Does this enhance the mechanical properties at all, more specifically wear on the parts, I’m wondering because I want to do this to some 3D printed gears but I don’t wanna go through the whole process without increasing the wear resistance.

[@perspectivex]

The copper spray adds a layer of conductive copper. Then you coat the copper with copper. Why not skip the 2nd copper coating and coat directly with the palladium?

[@hen3drik]

The copper spray just creates the conductive base layer for the „real“ copper to be plated on. It‘s like a soft paint you can rub off, but contains so much copper that it‘s pretty conductive. When I plate the copper in the bath, I add a heavy 240microns layer that doesn‘t rub off. The palladium is a very very thin few microns thick plating on the copper.

[@adrianli7559]

A few questions: 1) If I want the surface to be completely reflective (i.e. as few grains as possible), how would I go about it? 2) How much does the equipment + solutions cost? 3) Why the palladium? Is there a cheaper alternative? 4) How do I strip electroplating?

[@hen3drik]

Hi, long story short: have a look at my newer tutorial, they‘ll answer this. Palladium is optional, you can do nickel it you want, but palladium is actually not that expensive.

[@adrianli7559]

@@hen3drik Another question: how would you go about plating with an alloy (e.g. a brass finish)?

[@hen3drik]

@@adrianli7559 brass is easy: create a thick copper layer. Then on top electroplate a thin zinc layer. After that put it in the oven or treat with a heat gun for Brass.

It looks so good! At 3:10 you mentioned a brightener is added in the solution. What is that brightener?

[@hen3drik]

Thank you, a brightner is a substance that closes small spots on the metal layers, so that it develops a strong shine. It's in most of the commercial solutions. As it wears off by the time you can re-add it to have that effect.

[@TitansRevenge3D]

Found this on Twitter. I really like this idea. I have never done anything like that before, but I would love to start small by making "pirate treasure coins". Ironically I made that same Indiana Jones Staff of Ra file a couple of months ago and used dimes on the inside to weigh it down, then sprayed it with a metallic gold automotive paint. It looks great but needless to say it doesn't have the feel of metal to it.

[@hen3drik]

Same here, first made was of PLA the spray painted it. Second approach was gold leaf (still PLA), which was more convincing. 100% infill resin with plating is by far the most accurate thing I ever hold in hands.

[@R67K]

does it improve stability too? or is it just a cosmetic thing?

[@Voxrar]

Having trouble finding a good price for a conductive spray. Anyone got a link or suggestion?

[@MrGTAmodsgerman]

Does it make sense to electroplate a 3D print just for painting it after all the process? Just to have that cold feel.

[@hen3drik]

Depends. I do this for tactile parts (knobs, switches etc.). It also adds strength and weight.

[@MrGTAmodsgerman]

@@hen3drik What kind of strength does it add? You are the second source i found that says it adds strength, while when i google about that topic, there is nearly no mentioning of strength improvement. Only really mentioned is less wear and tear. Which could be considered as stregth, but only if you electroplate parts like gearings or something simular.

[@hen3drik]

@@MrGTAmodsgerman basically it adds stiffness. There is no bending on small parts: imagine printed parts, that bend, these become stiff as you put 25 micrometers of metal around it. Therefore it feels much more metal like. It also sounds different 😃

[@MrGTAmodsgerman]

@@hen3drik Interesting. Thanks for telling me. Weird that i can't find any video about the actual stiffness improvements for electroplated FDM or Resin parts. Like you would expect from CNC Kitchen or other channels.

[@QuixoticChaotic]

This is really cool. How much loss of detail is there for finer parts? Could I, for instance, plate a finely detailed mini or statue without losing too much?

This depends on the thickness of the coating. From my experience there is very few loss, because the paint is very thinned. Look at my video of the neuralyzer (latest). I am using graphite there, too. It’s really thin.

I get most my stuff from tifoo. Copper and nick elelectrolyte recover from the dissolved cu and ni anodes. Once in a while you should check ph and refill brightener. Keep it clean and it‘ll last very long. I recommend buying 5l. Make sure to get „acidic“ copper electrolyte, as it makes the conductive paint conductive at all.

I use a commercial acidic copper sulphate solution (incl. brightner). When the brightner (commercial) wears off from time to time, I add more. But it lasts very long. But Brightner is not the only thing that it takes; it‘s overall „cleanliness“, the right voltage, movement, temp. But yes, no brightner and you’ll need elbow grease.

Well, it‘s like any other plated metal. In total it‘s 200micrometer thick. That won‘t come off :-). The top gold layer is way thinner, this could wear slowly off if you would touch and rub it every day (sometimes this can be seen on cheap „gold“ chains, for example). So, image metal and you have a feeling.

Hello, Is there a reason you have to plate copper in between the paint and the nickel? Can you just go straight to nickel or paladium?

You could. But nickel isn’t depositing as fast as copper (what I recognized) and it‘s not as soft and polishable. Palladium would be way to expensive. I deposit thick layers of copper. Around 0.1mm-0.3mm.

[@hen3drik]

Yes, rumor has it that it does strengthen the parts a lot. Can you give me a link to the STL, so I‘ll try it for you. The copper layer itself is some 10’s microns thick.

[@Mr30friends]

@@hen3drik Unfortunately I haven't actually designed/printed any plastic gears yet, so I don't have any related STL files. But I am sure that there are free files on thingyverse and similar sites. The 10's micron thickness seems kind of negligable, at least for any structural strength, but who knows... But with enough wall thickness, structrural strength probably isnt the issue with 3d printed gears anyway. And the surface protection the plating offers, might actually matter in the durability and longevity of the gear since it will protect the contacting surfaces. If thats the case, what would the best metal for the plating? It certainly is a very very interesting topic, that would need a lot of experements. I mean, making homemade cheap and strong custom shaped gears is kind of a game changer. I also wonder how flat the teeth surfaces will remain after getting a very thick plating on them. After a while of electroplating, do things become a blobby mess in your experience, or are the features retained pretty well?

[@TheVideoGuardian]

That's pretty cool! Do you ever have problems with the metal flaking off? I would imagine durability is mostly up to how thick of a plating you put on, but the base coat might make a difference too.

[@hen3drik]

Funny, right now I am facing issues with copper deposition on a resin print (black mud on the copper spray). Flaking off was never an issue. Yes, the longer the dry time of the base coat, the better the durability (48hrs is fine); however, I usually begin plating after 30mins. Copper plating for 2hrs is giving me a good thick layer.

[@ProtonOne11]

Dont underestimate thermal expansion forces. Plastics and metals have very different thermal expansion, so you should try to keep the temperature stable from the coating with spraypaint until you have a thick enough layer of metal put down with electroplating. If you don't take care of that, the forces that build up between the plastic surface and the metal are strong enough to break the bond of the spraycoat, especially if you have parts with sharp corners where forces tend to concentrate into. Once the electroplating is thick enough, i guess the metal, especially the soft copper, can take up the force even when the bond between plastic and paint fails.
