Stronghero3D 3D Printing PLA Filament 1.75mm Bronze Rainbow Multicolors Net Weight 1KG Accuracy +/-0.05mm

The price is low and the quality is decent. The shiny and changing colors made for some really beautiful parts. I printed at 210c with a 0.4mm nozzle and 0.2mm layer height for functional parts on a cheap Tronxy X5. Aluminum bed with a layer of Elmer's Purple Glue Stick and it stuck down to the bed very nicely. It's strong, made some jigs to cut and drill aluminum parts and they held together with considerable forces.There were two issues. The filament is unusually brittle and the diameter runs wider than advertised. That made filament changing a pain. Very difficult because had to use pliers to force it through extruder and hotend since it's larger than holes made for 1.75mm filament, but it would break during most attempts because it's also a brittle filament. Maybe this is a moisture absorbtion issue? That's not common or expected for PLA, so that's an issue too. Because the filament was wider it would produce shavings as part of it is stripped off feeding through MK8 extruder hole to hot end. The shavings will fall onto the bed if you're not clearing them out. The shavings didn't cause me any actual problems, but definitely could have ruined a print or two under certain conditions.

I purchased this on sale not expecting the best filament. But it was a pleasant surprise. This is a standard PLA on a 1 kg roll. I printed 4 items and tuned it in about 205 degrees on the nozzle and 40 degrees on the bed. I used glue stick on the bed, with a cooling fan after the first 4 layers. The color gradiations went from a copper to bronze to almost olive and then back. The color changes a very subtle. You would need a large print job to get all three tones.The adhesion was good. The layers layed very nicely with minimal layer lines. There was a little fine stringing that showed on all prints. Overall for an inexpensive filament, I was very surprised an ordered a second roll. I see now that the prices has now risen to $15.99, which is still not bad for the way this prints

Great product all around and never arrives wet unlike almost every other available filament. And even alot higher priced versions to boot. This product is a really great value, ships and arrives fast, and prints better than you could ask for the price you pay. You wint find a better roll of filament for cheaper. Hell, You'd most likely be fairly hard pressed to find really anyting better than this all around.

So far the two things that I have made with this filament do not look bronze or any other color that the description describes. It looks like the color of peanut butter. I'm using it with a 3d pen. Perhaps the color would be more accurate on a 3d printer? The quality of the material seems very good.

It was pretty good overall just had to turn the temperature up a little but no issues and quality was good gives a cool look to what you make

Using a CR10 printer resulted in excellent prints with very good adhesion (glass bed/hairspray).I have used many varieties of filament with various issues including moisture, clogged nozzles, breakage due to bubble defects, etc. I wasn't expecting as good of prints as I got so decided to leave a good review out of pleasant surprise.

Dont know if this is clearance, or overstock, or just lesser appealing colors, but this is great filament. rainbow is just a get what you get setup, and that's fine with me!! 3rd spool of Stronghero3d and they have all been great.

Good smooth extruding.
