3D Printed and Copper Plated Jewelry ~ DIY Copper Necklace Pendant

Enjoy the evolution of this amazing project from concept to finished product. The wife loves it and I loved making it! She received this for Valentines day and I received a boat load of brownie points! I’m happy to answer any questions just let me know in the comments.

Get the Conductive paint I used in this video here:

3D printing opens up limitless options in so many areas, the particular printer I use is a DLP/SLA 3D Printer. Meaning it uses a high definition projector to cure liquid resin layer by layer until a final part is created. The 3D printer I own is a 3Dfacture Draken which I received after backing their kickstarter campaign. The resin I used in this video was Autodesk Ember Clear resin.

Multiple guides exist (including my own) on how to setup a copper plating bath. You’ll notice the pendant in this video came out of my plating bath with nodules all over the surface. This was due to having a relatively high pH. As a part copper plates hydrogen gas is generated, this slowly raises the pH. Since I had been doing quite a bit of plating before this video I should have done a test plate prior to plating this pendant. The results though weren’t terrible and as you can see in the video I was able to still make this into a beautiful piece of fine jewelry.

The electroplating process I used in this video is more complicated than say the one used in the video titled “Electroplating – Easy DIY Nickel, Copper, Zinc Plating” ( but it’s not so complicated the average person can’t get it to work. Comment if you have any questions please!!!

    Is the 3d printed piece plastic? How did you make it conductive? Thanks for the awesome video!

    The copper will make you "green around the gills" try a nickel / silver or gold plating after.

    you can use a cheap timer relay switch like this: to make a true forward/reverse plating setup. The 2 relays can be individually triggered/programmed and you need 2 leads from both cathode and anode, one pair cross connected over the relays. Set on infinite loop (function 5 or 6)you can for example set it to 10sec forward plating followed by 2-3sec reverse (deplating) since the current likes to travel the shortest way current density is highest on the high spots, that means in reverse mode material is removed predominantly from the "mountains" and less from the "valleys" this will cut down on the nodules . It doesnt completely prevent those but it helps if you set the cycle time right. Ideally the reverse plating cycle is done with a higher current density than the forward cycle - but thats not easily done with this simple timer switch. Also very short cycles(less than a second) will wear out those cheap relays much quicker - these are nor ment to operate continuously for a long time on microcycles. overall a cheap and readily made solution to add true forward/reverse capability to the plating bath.
