Prusament Prusa Galaxy Black, PLA Filament 1.75mm 1kg Spool (2.2 lbs), Diameter Tolerance +/- 0.02mm

This is BY FAR my favorite filament I've purchased thus far (Galaxy Black). I've already gone through two spools of this stuff and I've only been 3D printing for a few months. This stuff just prints with absolutely no issues at all. Love it!I am using this on my Prusa i3 MK3S, with the default Prusament PLA filament profile (215C nozzle, 60C bed). Most of my stuff was printed at 0.2mm layer height with the default PrusaSlicer settings.Pros:*This stuff HIDES LAYER LINES! Did I mention it hides layer lines? I mean, even at 0.20mm layer height, the tiny glitter particles masks the layer lines incredibly well.*I've had very good success with this filament. Never had issues with jamming, or problems with the PLA containing too much moisture right out of the bag. I've had issues with other brands!*Prusa goes to every extent to make their products extremely precise. You can measure the filament diameter for yourself and you will see that not a lot of other filaments are as precise as this stuff. They even have a report of the diameter of your exact filament as it was being wound onto the spool. Simply scan the QR code on the side of the spool and it will give you the report! What other filament brand does that?*I have never seen a more beautifully wound spool of filament than the Prusament brand. When you open the vacuum sealed bag (which is reusable by the way!), you will notice how perfect the filament is wound up. If you've ever had a print get ruined because the filament spool getting tangled, then you know how frustrating this can be. Not something you have to worry about with the Prusament brand. For people with OCD like me, you will love the winding of this filament! It's perfect!Cons:*This stuff is expensive! At $30 bucks a spool, this is more expensive than most other PLA you can purchase on Amazon.*At times (when sold out) this stuff can be very difficult to get your hands on. I usually order 2 spools at a time since when they are sold out, it can take up to a month or more before Amazon receives another shipment of Prusament brand filaments directly from Prusa himself. They have a pretty small filament production line, so when it's out, it takes a little while for them to ship more pallets to Amazon from the Czech Republic.Overall:I love this stuff. It's a huge upgrade from the silver stuff that came with my printer and I think what makes it stand above all of the other filaments I've used is how well it can hide layer lines. I love this stuff and would highly recommend it. Only bad thing about it is how quickly I run out of this stuff!

I am new to 3D printing, and this is the third spool I have used so far, if I can count the generic 250gr spool that came with my Creality Cr-20 Pro. And honestly, that generic white filament was not bad. Then I bought Proto Pasta, which is good, but comes at a quite steep price considering it cost the same as the Prusament Azure blue but weighed half as much. The Prusament is fantastic. Prints extremely well, it is exquisitely spooled, and, believing Prusa, it has much better tolerances than filaments that cost the same or more. For half the price of Proto Pasta (weight considered), if anything, it is better. The perfect spooling is not decisive on the quality or print you are going to get, but along with the very nice packaging, included zip bag, and information on your very own spool, it screams attention to detail that might very well translate into a very high quality product. And so far, that's what it appears to be. I would say that if you can find it even at $40, go for it! For $29, the price at which I got it, it's a steal!

I suppose I shouldn't be surprised though. I have a Prusa MK3S and am very pleased with the reliability and quality that it routinely prints. I decided to try Prusament Galaxy Black to see how well the filament works, even though it is expensive compared to other PLA filaments.First, I didn't expect the embedded silver flecks, but honestly it is a very attractive effect,Second, I expected the filament to print well and I wasn't disappointed. I cranked the fineness/thinness to the minimum allowed by the printer (0.05mm) and printed a set of very fine-toothed gears. The filament performed spectacularly.One minor concession I needed when I wanted very fine prints is that I needed to print a little slower, but that can be expected for cooling and less smearing on very fine prints.In summary, the filament is as good as it claims, at least in my opinion. It is a little pricey and depending upon what you intend to use it for, the higher quality may be wasted. I would buy it again though.

Printed a couple things with this now. When used as a first layer (with an alternate layer after that), it can be translucent. However, when it is on top, it is a nice, opaque finish with glitter to finish. When I used as a first layer, it didn't stick as well when I used default PLA temp settings (210 C), but when I upped the temp to 220, it stuck very well.One thing I noticed was that it really doesn't string - it's quite nice in comparison to many other options. It seemed to have quite good layer adhesion (I even swapped filaments between brands in a print and this stuck really well). It also "hid" layer lines with the little glitter it has. All in all, it is a solid, high-end filament. I don't know that it's a great value, given how good the "cheap" filaments have gotten, but this will remain something I keep around for those more important or more difficult prints. Just be sure to print a little hot... :)

This filament prints very well. It is an off-white and very attractive. Like another reviewer, I was using this for a lighting project. I found this to be in the middle ground of transparency/diffusion. I tested this filament along with with 3D Solutech Real White and CC3D Silk White, I found the silk to be the most transparent / least diffuse - which for me meant it had hot spots where you could see the LED behind it. The silk also didn't print very well and left a lot of visible artifacts. I wanted to like it better. The Prusament printed well and was in the middle. I could still see some hot spotting. The white printed nearly as well as the Prusament, and diffused very well (trade off being the lowest in light transmittance).
