HZST3D Gun Metal Grey PLA 1.75mm 3D Printer 1kg (2.2lbs) PLA MAX Color

This is my favorite filament. Never had any issues no matter what I print. Filament is plain, looks normal, nothing special, which is exactly what I wanted.

This filament is fairly generic in performance. Layer adhesion rates about 7/10, which is decent but not exceptional. Overhangs tend to warp, which can be frustrating, though stringing is minimal, so cleanup isn’t too bad. Bed adhesion is generally reliable with proper surface preparation. The advertised metallic appearance is hard to achieve unless you’re working on larger prints and running the heat at the upper limit of the recommended range. For smaller prints, it doesn’t really capture the gunmetal gray look I was hoping for. Overall, it’s nice to have as a backup filament, but I’ll stick to higher-quality options for projects where finish and appearance are critical. (Left benchy)

That picture is a spot on the print (which had been spray painted) where I slammed the claw end of a claw hammer onto the piece. It was printed at 210 C, with 3 walls, 10% infill, and 0.2mm layer height, and didn't fit where it was supposed to go because I miscalculated something. So I tried to break it. Even standing on it did nothing. I hit it with a hammer with enough force to drive a nail, and nothing. Finally, I hit it with the claw side of the hammer, and got the tiny marks you can see above. This material is simply amazing.

I picked this up needing a gunmetal color and on sale. I have been printing since the reprap days and this is the first pla filament that I have throw in the trash. I did increase the temperature to 235 and was able to get some prints out of it but anytime I had a large job it would at some point clog the nozzle. After the 3rd clog, it went into the trash. Whatever additive they are using in it really is messing with my nozzle.

I love this filament color, print quality, and overall strength for doing new prints. For the price, I like having a standard printing filament to use. Often times it's a cheap white or black basic PLA/PETG. I've since decided to use this. I love the gunmetal color. It feels like a nice offset from a gray or silver and it's more exciting than a white/black. Features printed with this really stand out. I run it around 220C and have not had any issues with adhesion at 60C (but I used glass and adhesive 100% of the time). Highly recommend this to anyone experienced or beginner!

This stuff likes to be extruded a little hotter if you are using a ender but besides that prints fairly well and consistent. And it actually survived a accidental print at 260c and 90c bed temp and didn't fail at all or have bubbling

For the price, I can't complain. It has printed everything I have put it on and with a little adjustments here and there, more on the machines part, it turns out pretty darn good.

It works, only complaint is it looks as it was possibly rewraped? The filiment goes all over and sometimes get stuck becuase the dowel is not rolled correctly, but after rewrapping on my own it looks much better and functions.
