## Description

desertcart.com: Protopasta Brass Filled PLA 3D Printer Filament | ProtoPlant Metal-Filled PLA Plastic Printer Filament with 60% Brass | Polish and Patina Friendly Metal Composite Filament | 500g Metallic Spool : Industrial & Scientific

Review: Great filament! Works exactly as described - Very cool filament, prints easily and functions as described, magnets stick to it and it's easy to get that rusted look with a light sanding and spraying a mixture of hydrogen peroxide, vinegar, and salt.
Review: One of my new favorite filaments! - I know that some people are reporting issues with using this filament, and to be honest, it is important to not use a brass nozzle. I use a .4mm steel nozzle on my Anycubic Mega Pro without any issues. The filament is wound nicely on the reel, and the prints are beautiful. They have a heavy feel to them, and have some slight magnetic qualities. The only downside that I have found is that the amount of material on the reel is significantly less and the cost is just a little high. But if you want a nice looking, and feeling print then you might want to give this a go. Just don't forget to upgrade that nozzle!

### ⭐⭐⭐⭐⭐ Like metal, but also a bit like like pottery or stoneware.
*by A***R on November 9, 2025*

I love how this stuff looks feels and sounds. This looks like metal once polished, weighs about right amount, works with my ender 3, has the heat conduction of metal, sounds and pottery or stone, but a bit tougher.
