Proto-pasta CDP11701 Electrically Conductive Carbon Loose Coil, PLA Composite 1.75 mm, 125g, Black

I picked this filament up to see how it would do in terms of electroplating. It works, but works much better with small pieces. A 1cm cube plated nicely in just a few minutes. On the other hand, a complex figurine (3.5 x 3.5 x 7.5 cm) with lots of branches and a lot more surface area takes hours. You will have to "mask" off fully plated areas with shellac or some other insulator to insure that the rest of the figure coats evenly.The filament is brittle, leading to broken feeds - keep a close eye on it while printing in case it breaks and you have to pause printing to re-load filament. Printed objects are also fairly brittle, but this actually helps with sanding and post-printing treatment.It's an acceptable solution for very small, low surface area objects that you'd like to plate. For non-tiny objects with more surface area, the conduction isn't high enough to make plating easy. Graphite paint will be a better alternative for many people, as you can use lower cost PLA. That said, $15 for a sample roll will let you try out your project at a low cost and see if this material does what you need.

I purchased this conductive PLA to prototype an electronics device case that will eventually be fabricated in aluminum. 3D printing gives me a jump on modeling parts: it is faster and cheaper to use FDM at home than contract someone to make these parts using CNC. What I needed for this project was a grounded case for ADC noise reduction. I was expecting conductivity in the meg-ohm range at best. But when I printed the part (it's about 4" x 2") it measured under 10k resistance from end-to-end! Excellent!And the measured ADC noise of the product was astoundingly good. This PLA has fantastic conductive properties and was just as easy to use as any PLA filament I've tried. I'll be buying more; probably a LOT more.One caution I want to mention: since this product has metal in it your hot end should be stainless or have an abrasive resistant coating. Brass nozzles may get worn down which will lead to all sorts of printing problems.

This stuff is pure genius. My applications are mostly high voltage for this stuff (plasma engines and what not) so the resistive properties work out just fine. On that note, I printed out a potentiometer. It didn't turn out the value I wanted but that's just because my math was off. It's tricky to print with but I turned it up to 230C and reduced my printing speed to 90 mm/s and it prints flawless. Too cold and it will clog, it happened once. Update: Got my math right this time and sucessfully printed a 10k Potentiometer. I need to buy more of this wonderful stuff.

So I have been using this stuff for a while now and it always works great, I had a small project I was working on and saw that this was just a small amount at a much lower price, so I figured why not since this was just for a small personal project. I got the filament and it was in a vacuum packed bag. As soon as I opened the bag the filament rolled immediately unwrapped itself and got tangled, there was a rubber band to keep the material spooled but it was broken. I spent a little over an hour untangling this filament mess. If you buy this make sure you have a spare spool to wrap the material on and be careful about it. Overall I highly recommend spending the extra money and just get this this stuff already spooled.

Works as advertised, it prints easily and conducts -- but not nearly as efficiently as anything metallic. For the right application this can certainly work.One thing to know: the graphene fouled up my hotend like nothing I've ever experienced, and I've printed with a pretty wide range of composites (wood, carbon fiber nylon, carbon fiber polypropylene, weird colors, etc.I had to run maybe 2-3 meters of cleaning filament, multiple cold pulls, etc before the graphene stopped visibly tainting the extrusion. This isn't a huge deal, but this isn't a "swap in, swap out" filament.

I was looking for filament that I could use to construct a capacitive stylus for individuals with disabilities (you can find it on Thingiverse - thing 2749954) and this worked really well. I wish it wasn't so expensive. Also, being a loose coil is a real pain when it comes to loading this on your printer. I scrambled to find something on Thingiverse that I could use as a spool. The filament printed nicely on my Prusa i3 MK3 with no special adhesive needs.

Changing my review to five stars because, when I reached out to their support, they asked a lot of questions about what I was trying to do and we confirmed it wasn't the right material for my job. The prints were beautiful but had more resistance than would work for me. I have to say, after dealing with them, I would not hesitate to purchase one of their products!

A bit hard to work with. The filament easily breaks when handled, and also tends to strip out in the extruded. Seems to want A LOT of tension.However at the end of the day I did get this to work and I was able to make a custom touchscreen stylus for a physical disabled person and it worked well. I do sort of wish there was a conductive ABS though so that the final product would have a little heat resistance and could be left in a vehicle during the summer months.
