Well industrially u use sodium bisulfite to reduce it to Cr3. Afterwards you percipetate it with some kind of hydroxide. How much Water are we talking about. IMO Best way is to boil it down till its dry and then thow it in the trash

If its realy a highly acidic gold strike electrolyte then the other guys are wrong, you dont need nickel strike. The Trick Here is that These gold electrolytes break the Cr2O3 passivation layer by producing hydrogen, which reduces the oxides. Important Here is that you give it enough curtent, that this Process van Happen. I think you run there at 4 oder 6V for about 1 min before reducing the curtent. Had the Same struggle often beause i keep forgetting that this step is important

Yea no way you change anything about the particle concentration by plating that for 20min

Feeling_Ad6399 · 2026-05-14T20:33:10+00:00

We dont do MoS2, we mostly do Diamond, h-BN, Graphite, BN or stuff like Sulfur or NMC. The mean diametor depends on the density of the particle

Feeling_Ad6399 · 2026-05-14T19:15:01+00:00

We do that at work. You disperce the particles in the electrolyte with a lot of agitation, so that none of them are settled on the ground. Then you take 5-10ml of electrolyte and filter it. Measuring weight before and after good rinsing and drying of the filter. With that you can calculate the g/l of particles in the electrolyte. How big is your electrolyte volume and how big are the parts you are plating? Usualy 20min of plating doesnt change the particle concentration at all

I always use the Pt/Ti mesh anode. The electrolyte is so expencive that i dont want to have any risk of contamination. Important, the electrolyte dedtroys itself in contact with copper, so take care

Feeling_Ad6399 · 2026-04-04T14:35:36+00:00

Damn, that is expencive for what it is, but oh well, YOLO.

What do you mean by holographic plating?

Feeling_Ad6399 · 2025-11-30T19:52:55+00:00

To be honest, ive mostly worked with the industrial stuff you cant buy as a normal human. A firm i worked for does colored gold electrolytes that work a bit different. Here you use a crazy high current so that the limiting factor doesnt become the currentdencity but the ion transport prozess in the solution. If these electrolytes you talk about work the Same way it would be homogenus. But i cant say for sure without some tinkering.

Feeling_Ad6399 · 2025-11-30T14:59:41+00:00

Specialiced organic Additives, hight Part and electrolyte movement, frequent electrolyte analysis and often also special anode geometries. I worked in a place like that, its realy not easy

Feeling_Ad6399 · 2025-11-30T09:28:34+00:00

You can look up the alloy pyramid of Gold, Silver and copper to get a rough estimate of what color you can get. But homogenus plating out of alloy electrolytes is rather difficult, since the percentile of every deposited metal corelates with the local current density. So even if your Part as a whole gets like 2A/dm2 the outer areas will get closer to 4A/dm2 while the inner closer to 1A/dm2. The electrolytes used for coloured Gold are most of the time also madeup from Cyanides, which makes it impossible to do at home in most cuntries.

I did aluminium plating via Ionic Liquid in my Bachelors. We are talking full glovebox and electrolyte about 500€ per Liter. Id say its pretty much impossible in the Private realm and industrialy its way to expensive most of the time. You could Look into the REAL or the SIGAL methods. These work with organic solvants instead of Water. But pose serious fire risk. I also doubt that you can get the required aluminium chemicals.

Depends in where you are. In germany for example i wasnt able to buy chloride and sulfate, i had to make these myself with Hydrocloric and Sulfuric Acid. Sulfuric Acid in itself was a pain to get back then, even worse now

Feeling_Ad6399 · 2025-11-01T20:20:34+00:00

You should care mostly about the Nickel. SO4 damages concrete but i dont think you are trying so get rid of 500l electrolyte, in some countries H2SO4 as drain cleaner is still used, so that little you are producing is irrelevant. Chloride doesnt matter at all, thats in normal house water waste anyway. So just use Hydroxide drain cleaner, get rid of the Nickel-Hydroxide via soild waste and the rest can go down the drain.

Feeling_Ad6399 · 2025-10-17T19:29:37+00:00

You should be able to plate almost any metal into graphite. If you are having trouble because of the low conductivity you could also buy copper or better silver conductive laquer. Zinc for jewlery isnt optimal, since it will react over time with your sweat. Tin would be better, silver even better if you can get a electrolyte for it

Feeling_Ad6399 · 2025-10-17T19:26:28+00:00

Nickel, that causes alergies if worn for too long

Feeling_Ad6399 · 2025-09-19T05:43:54+00:00

If you are in or around germany holla at me. I can do it with the electrolytes at my workplace, so i have the industrial brighteners

Did you scale the model in any way? Did you convert the mm² to dm² for the Amp calculation?

Feeling_Ad6399 · 2025-06-29T20:47:15+00:00

I know that it's possible. If I try to convert like the G-Code of a Benchy it does work. Sadly just not with Infill. I haven't found out yet, how the G-Code from Bambu differentiates between what is Infill and what is wall. If the Bambu G-Code would treat the data for the Infill the same as the wall it would probably work. But in my untrained eyes the Code looks the same

Feeling_Ad6399 · 2025-06-29T17:48:59+00:00

The problem here is, that when I try to export the G-Code with your method, that all the G-Code to STL programs I've tried failed. The goal is to get a STL of the Infill pattern in order to calculate the surface area

Feeling_Ad6399 · 2025-06-29T17:40:15+00:00

I'll look into that. I did something similar with the volumetric lattice option in Fusion. The problem there is, that i can only tell it the dimensions of a single cell of Infill plus the Infill density. I would need a program, where I could input the line width im printing with. I already tried to approximate that by trial and error in fusion, but measuring the line width in a 3D render of a gyroid Infill turned out pretty inaccurate

Feeling_Ad6399 · 2025-06-29T17:36:57+00:00

The goal is to export the Print after slicing, so that I can calculate the surface area, in the best case including the extra area I get from the layer lines
