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

Highest quality pasta, prints are consistently reproduced with standard settings. I am going to be trying the other types of filament this brand offers.

This is really cool but only for specific uses. It prints great and looks great but it isn't very strong, it’s expensive and it’s extremely abrasive. That said I am really happy with this stuff I just wish it wasn’t so expensive. You’ll want to use a steel nozzle. I had the best results at 235c.

So far this material is very well made, you can get a good finish on parts made and I have gotten the rusting solution to work on it, which I do plan to layer a clear coat over it for protection and to keep staining anything else to a minimum, but this is a fair warning to everyone using this material about it's weight,It's stated to be 40% brass powder in mass, which means you have less PLA by weight. From my back of the napkin math about a peice of filament from normal pla at 4ft is about 4 grams, but this metal mixed filament is 7grams at the same length of filament. That means the length of the full spool of material is roughly half of what you would have otherwise, so when I made my parts in the slicer showing the total weight I underestimated the amount of material I needed, and had to keep restocking spools as a result.So after my 3rd purchased I can finally finish my parts I wanted even though I thought I would only need about 1kg to print, my first part i made was about 50%heavier then I expected. But after I thought about that issue and it made sense as to why.But other then that I have had absolutely no clogging, the print quality is about perfect!(exceptions to the spots where I had to stop the print and wait for more material to arrive, that was user error at best and will be covered by the sanding anyway), the color is a bit underwhelming fresh off the bed but comes out well after sanding, and the InstaRust solution does work, but it needs time for the parts to corrode unlike a fresh peice of iron, feels heavy and strong so it's functionally the same as having a part made of metal, the price is just a bit high for the product.But it does work as intended so that's not a downside worth worrying about, unless your like me with 1 color printers only, but I would highly recommend using a printer with multicolor print options, as you can save greatly on the cost and just do a over coat of metal filament to get more bang for your buck, and use a cheaper material for the infill.(Side note) You can use a brass nozzle to print this material, I was worried about clogging or eroding the tip but after my first spool came in it was left running for almost a week straight with no issues, the fancy new hardened steel tips I got for this specifically clogged immediately, but that may be due to the tip not getting heated enough, which was odd considering it worked for about 20 seconds into the first layer then stopped, but the cheap brass tips worked out the gate and haven't failed as of yet after 6 days of continuous use. I worried about this before purchasing so I hope this will help the next person who has the same question.I will try to add pictures after the print is completed!

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.

Prints really well, print comes out heavy feeling almost like some metal although it will not stick to a magnet. Feels sturdy! EXPENSIVE THOUGH<

first time using this on a large print it clogged my nozzle hard at about hour 14 of 16. I can't get that nozzle unclogged with a butane torch! It did not have any issues up til then. First layer was good, and it came right off the plate no problem. The supports pretty much fell off of it. The hotend was so jammed up that the filament cutter was stuck in it. I was hoping to review this after printing a larger piece and testing it.

I have to admit I wasn't sure this stuff would really work. I like to 3d print a wide range of products from simple art pieces to complex motor drives. I usually end up 3d printing a mold blank, making a sand mold of it, and pouring it up in metal or making a compressed carbon fiber mold instead. I bought this to experiment on a brushless motor design i was working on and found it to be superior to the iron powder and epoxy technique i was using and didn't require 1/2 the work. I also 3d printed a couple test statues 1 to rust and 1 to electroplate found the rusting quality for aging worked very well however i had to use a special paint to get it to electroplate evenly. was able to print using base pla settings and it printed all parts with fewer then expected blemishes then expected. All in all its a great product.

The media could not be loaded. So this stuff is pricy but fun. Layer adhesion, as expected, is terrible and I am unimpressed with the materials mechanical properties. None of this is super surprising though, this filament exists to be fun and to print cool trinkets.Prints initially look dull with a weird and matte finish but polish very nicely. Attached is a, completely safe, prop of a brass cylinder that has been polished after printing. Very happy with this material.
