Prints like PLA and is Awesome 🤘🤘
Phenomenal filament and all interactions with Protopasta have been great! For this project I used both the Copper and Iron Filled PLA for birthday Maker Chips and then came out better than expected!!!

Great Filament
This filament is pretty cool. Printing with it was a breeze, I printed with regular pla settings and got no clogs or stringing and layer adhesion was wonderful. Sanding it gave it a rustic color that looked smooth and polishing it with a glass file made it shine wonderfully. The price is a bit much but you are definately getting what you pay for. Very solid material. I do wish it would patina a little more but it does patina quite well and enough to be satisfied. If you're looking for a real copper filament, this is it.

Heavier than pla! So neat to print with!
So cool. Takes time to patina, but is so cool!

Copper Filled PLA
Product printed as designed, with no visible defects. Product however did not shine/polish as identified by the manufacture.

Good filament
Used the filament to print some house numbers, worked great

Awesome but don't be fooled by the weight vs distance of normal PLA
This stuff is great and oxidizes but beware it's sold by weight not length so it's maybe a 1/3 of your standard 1k roll.

It looks nice, but my printer gets clogged with it
I like the quality of the filament but the filament itself even after opening the package was very brittle and clogs my printer. No idea if my printer can't handle it or the filament is poor.

Great, polishes nice but it's not conductive like I thought it might be
I guess 15% copper by mass isn't enough to make this material conductive. I checked the print and the material on the spool. Both are not conductive so while it didn't work for my application it "IS" very nice stuff and prints very nice.
