ReFil 3D PLA Black 1.75 mm 1KG Spool 3D Printer Filament (.05 +/- Accuracy)

Out of the box this filament *will not print* (for long). It's too brittle: It'll break on its way to your extruder which is *crazy* and kind of impressive (impressively bad)! Why did I still give it 3 stars?!? Read on... Skip to the part about "HOW TO FIX IT" if you don't care about the rest.The bag is "sealed" but not "vacuum sealed" (if you catch my meaning). Also, the included bag of desiccant is garbage. I opened it up and it doesn't even appear to be *real desiccant*! Normal desiccant comes in a variety of colors and "really dark grey" isn't one of them (haha). So that probably explains what caused the problem with this filament: It absorbed waaaaaay too much moisture while sitting in a warehouse somewhere and during shipping.HOW TO FIX IT: Get a quart or two of some silica gel desiccant (I like the amber/green "color indicating" kind), put it in an old pillowcase (so it doesn't stick to the filament) and put both the desiccant and the pillowcase in a sealed plastic bag or container of some sort then SHOVE IT IN YOUR TRUNK FOR A DAY. Park your car in the sun for max moisture minimizing power (unless you live somewhere like Arizona--don't let the temp in your car go over ~60°C/140°F). IMPORTANT: Do not remove while hot! When the desiccant heats up it too will relieve itself of any moisture it contains so the key is to let the filament spool and the desiccant cool (slowly) at the same time. The desiccant will absorb moisture like nine bazillion times faster than the filament so after a day in the sun it should remove enough moisture from the filament to make it usable.After moisture removal the filament prints fine but it's not really the best looking black filament. Is it worth the $9.60/kg I paid? I think so! Great for quick prototypes and stuff where looks don't matter. Layer adhesion is actually great and the parts I've printed so far have been as strong as normal PLA.For reference, the 3D Benchy (the boat) which was printed at 215°C but after several prints I've decided that 210°C is better since there's a bit of stringing at 215°C. Using an Original Prusa i3 MK2 with an E3D V6 hot end and a brass nozzle.

I gave this an extra star because it was so cheap. First prints failed because of bed adhesion loss, which is a problem I never have. Printed with a 2mm brim and that solved that. The print temperature range on the packaging is listed as 180°C to 240°C. I started at 210°C and it was the hairiest print I ever saw! Increased retraction and dropped to 205° and it was better, but still bad. I went higher on the temperature and it got worse and the print took on a brownish color. Started dropping the temperature down and ended the stringing at 187°C. The color was also now better than it was at the original 210°C. Now I'm wondering if bed adhesion may have been a factor of the print temp being too high. Since I prefer to not print with brims, I'll try from the beginning at 187°C and no brim and I'll report back on that. Under 200°C is unusual for PLA on my machine. Update: Adhesion appears to have improved with the lower temperature, stringing still occurs but it is very fine and not near as bad.

I purchased 10 rolls of this at work and for my home 3D printers. I used this on 4 different types of printers with different extruders. It printed fine for some and breaks off on most models and as soon as the printers are done and the filament sat for a few hours it will turn brittle and breaks off, requiring me to re-install/feed the extruders happens every time. This filament must be old batches and hence the reason why I was able to purchase for less than $10.I'd rather spend more money which I had to do around $15-$17 and get better quality filaments. I guess this seller doesn't care about selling quality products! I'm not at all pleased that I wasted money on the extra rolls.

This isn't the best filament I have used but for the price it's still pretty good stuff. I had a little problem with adhesion in spots, dime to quarter sized areas in the middle of the print but more cosmetic than anythingAlso the plastic bad could be slightly larger so it can be better sealed when put away and the desiccant pack wasn't nearly large enopugh especially since the bag can't be sealed so I docked it one star

it was ok the filament is a little brittle which broke here and there but its not too bad but I won't buy it again unless it was really cheap and I mean cheap

Prints very well, and is available for a great price. We like that it is a deep black and not greyish or blueish.

Filament breaks at the feedpoint due to excessive brittleness even though I'm using it fresh out of the package in a low humidity environment. Crap filament not worth buying again.

Got it to run fairly well until the last 3rd of the spool. Then it became very inconsistent.
