Protopasta 3D Printer Filament | PLA Filament 1.75mm | Copper Filled PLA | 500g Spool

I printed this using slower PLA settings at 205c on an Ender 3 with no issues. When polished the filament looks like copper as advertised. Parts come out looking like terracotta at first and have a similar feel and density to them. Printed parts have a very nice feel. The filament is substantially weaker than regular PLA and should not be used for structural parts. Because the filament is fairly brittle you should use a filament guide or keep the filament from having to take any sharp turns.

Love the look, love the weight of this filament. It comes at a price, i'm ok with it. But IDK if its all rolls or just bad luck on mine. But this roll came with way too many tangles. I got this today and printing a larger print where I've had to stop the print 3 times and counting because of how the roll is tangled.

Disregard the shaving issue I had on the bottom layers. That has since been cured. But look at the finish I got on my first attempt here. Using suggested settings from Proto-Pasta on my CR-10 V3, this wall hook I printed out came out very strong. It looks more like terracotta when printed. Next one out I'm going to sand and patina it. My goal was to print some custom bases for my desktop sculptures.

Surprisingly easy to print with. Layer adhesion isn't great might be me. All of my prints look great with small to unnoticeable layer lines, but any drop or stress pulls them apart.Really the shine looks cool. People like the weight. Getting them to patina isn't great. And there isn't much out there for instruction besides sand and vinegar/salt.Steel nozzle is a must

I ran this on an Ender 5 Pro, at 205°C nozzle, 60°C bed, with a .6mm hardened steel nozzle; all suggested settings for this stuff. The filament fed for all of 3 seconds, and then stopped for some reason. I thought maybe it needed to be re-fed, so I attempted to un-feed the filament and it required such force to try to get out that it broke off inside of my bowden tube. I now have to unclog that mess, as something clearly went wrong near the hotend. Don't buy this. For $45/500g spool, you should expect better, more durable packaging, and filament that prints consistently, and doesn't break your printer.

I love the way it prints. Almost no post processing is required. I buffed the print to bring out the copper sheen, but otherwise left it alone.

Bottom line: $50 for 90m is steeepDefinitely adjust the material weight for this filament so you don't run out of the spool: 2.3 g/cc is heavy which means that 500g only gets you around 90m of filament in a spool.With some sanding and post processing, this really does shine like copper which is super cool for a 3D printed object like a pot or figurine.At 50% more $ per g than Colorfabb, think I probably won't buy this regularly.

material is very soft and brittle. the end of the filament was not secured properly and my filament broke off at the dual gear extruder due to tangling on the spool. I wasted more than i would like getting that fixed along with dialing in proper temps for adhesion.
