Gizmo Dorks 1.75mm Metal Copper Fill Filament, 1 kg for 3D Printers

I am very disappointed as I bought this filament under the assumption it was 25% copper. After printing a 3 cm x 3 cm 3 cm cube I discovered the cube weighed only 30 g (meaning it is nearly all PLA). If this filament was 25% copper and 75% PLA it would have a density closer to .25(8.94 g/cm^3) + .75(1.24 g/cm^3) = 3.17 g/cm^3.For comparison, Colorfabb has the density of their copperfill filament listed as 3.9 g/cm^3 (this filament is much more expensive however). If this filament was 25% my 3x3x3 cm cube would weigh about 80 g, not 30 g. This filament does print nicely however and the dark copper color is great for busts.

It's just enough copper to color it and nothing more. Was wondering how they could sell it for about $30 a kilo when Colorfabb's is more like $100 and that explains it. Doesn't have the increased weight/heft of a metallic object such as what Colorfabb's provide. You also can't age it with aging solutions to add a patina like you can with competitors. It basically is just pigmentation.

This is, so far, one of the lowest quality filaments I have tried and I would never buy it again or recommend it to others. Unlike many filaments, this one has a very narrow range of printable temperature. Be very careful about printing temperature calibration for your setup before using this. For me, 185 was the only really decent temperature. And even then, there was a lot of stringing. It is easily the stringiest PLA I have ever used.This is advertised at a "bronze metal" filament. Is this color bronze? I would say no. It's kind of a greenish beige, or khaki. Granted, there is a lot of variation to bronze coloration, but usually it is a bit deeper and brownish/reddish. As this is not a silk PLA, there is nothing particularly metallic about it. It is less shiny than many other solid color PLAs I have used.Looking for something nice to say about this filament, I can attest that it will print under perfect conditions. If you really take the time to print off calibration tests to make sure you have the right settings for this filament, you can get a good print. This filament not being a silk/metallic has the benefit of not being brittle like those types of filaments are, so if you need something to look sort of bronze without becoming brittle, this might be an added benefit.But for me, the effort versus the reward on this one means I would pass on it every time. This is neither good filament nor does it look like bronze in any stretch of the imagination.

I have seen some bad reviews on this product, but I think they are due to people not reading the description and specs. I love it! The small amount of copper in this product gives it a very nice color and a sheen/glitter when you turn the prints toward a light. The best way to describe it would be the finish of an old penny maybe. You cannot, in my experience, bring it to a shiny, gloss finish. With some steel wool, you can bring out more of the copper flecks in the PLA, but it will always have a matte finish since it is 95% plastic. If you are looking for a copper color, this is it. If you are looking for a copper finish, you are going to have to pay for much more copper than this.

I liked the look of the prints from this filament. However, I intended to use this to patina the copper print. It has so little material that will oxide, it doesn’t work. A photo in the description shows a patina. I used vinegar, salt & ammonia on a roughed print surface. Left it for a week & nothing notable at the end. Overall the filament is ok, it just didn’t produce a patina.

This is a love/hate filament for me. I've gone through about 30 spools of it, and about 5 spools were rubbish. I'll see stringing, inconsistent extrusions line by line..... but then I dry it out and it's fine for a day at 20-30% RH. When it's bad, it's really bad. Stringing, impossible to remove supports, just rubbish. I live in a desert, so humidity normally isn't a problem for me but with this filament I've had to use my dryer more than ever. In the end, I've tossed 5 spools of unused to go with another supplier. I'll only use this stuff if my new supplier cannot meet my demand of 10 spools a month, and even then it's going from the sealed bag to the dryer before printing.

Layer adhesion is fine, the filament itself is somewhat brittle but I haven't had to many issues with it so far.It looks nice and bronze-y and if you look very closely you can see very tiny sparkles which I would assume it's the bronze particles.That said it probably has hardly any bronze to be significant as I printed two Benchy's with the same gcode, with one being regular PLA and the other being this "bronze-fill" PLA, and both of them weighted the same on a kitchen scale.Overall, shame that it doesn't claim to be what it is but it does at least have a nice color, prints sufficient.

I bought this after reading the "answered questions" where the seller confirmed it is 25% copper powderThis product contains very little to no copper at all. My best guess is there is a copper colored mica powder in the PLA, to give it the color.If you want a true metal filled PLA, go somewhere else.

Doesn’t contain metal whatsoever. Better spend more and get what you want
