3D Printer Filament PLA Filament PETG 1.75mm Filament Dimensional Accuracy +/- 0.02mm 1kg Spool 1.75 mm Pack of 1 (PLA(Polylactic Acid), 01pla Rainbow)

Good quality PLA for 3D printing. It has good adhesion, easy to print and handle like other good PLAs.The spool came in vacuum sealed with a desiccant pack inside, and the whole thing was boxed to protect it from the adventures of mailing. The spool was not nicely wound up like some high end filaments out there, but I never had any issues with tangling and it unwinds pretty easy.On my own Artillery Sidewinder X1 (glass bed) I used the following settings: E - 205C, Bed - 70C (I think you can easily go to 60C after the first few layers, but I did not try it).The layers adhesion is pretty good at these settings and feels strong enough for my likings.The only downside of this filament is the color change is too "slow". For example, I printed some test models to play with adhesion and those came up the same color. The models were small enough for the color change to notice, they used about 5 meters of the filament only.Tips to make the color change happen faster: print multiple items in parallel on the same bed or use more infill. I would probably stick with the former option as increasing infill will be probably a waste of material.Larger objects should come up better. My own rough calculations show it should use at least 15-20 meters of the filament (this parameter is normally visible in your slicer next to the estimated printer time).Anyway, even for general printing this PLA spool is pretty good for the price. The only suggestion for the manufacturer is to add another version of the same filament with faster color change to support smaller models.

I held off on buying this for a long time; Seeing "My prints don't have any color change in them!" in so many reviews. I noticed some folks pointed out if you have a large printer and print a big object it'll work great, so I bought a spool to try it for myself.Look at the photos, they speak for themselves. My JGAurora A5S has a build volume of 300 x 300 x320 mm, and I'm running a 1 mm nozzle on it. I got the triceratops model off of Thingiverse and upscaled it. The printed model from head to tail is give or take 12-14 inches long. The model has four perimeter walls, and if you look at some of the photos you'll see it has a 20% grid infill and needed a LOT of support material. The print took nearly 800 grams of filament. Consider that a full spool of this filament weighs 1 kilogram (1,000 grams), so I used up just over three quarters of the filament on the spool.So, if your 3D printer has a small build volume, this filament is going to disappoint you. The filament changes colors every few yards or so, and a small print just isn't going to push enough filament to introduce a color change on your print.But if you have a 3D printer with even a decent build volume, pick an intricate model that requires support material and/or make the print more solid by adding additional perimeter walls and increasing infill percentage. Choose good settings for your print, and it'll turn out as good or better than the Triceratops I printed!The triceratops took about 40 hours to print. I had zero issues from this filament. It extruded nicely, stuck well to my printer's glass build plate (smeared with glue) and I had no flow issues (though it's really tough to clog a 1 mm nozzle!). Should I want to print another giant model with unique colors, I'll be back to buy another spool of this filament.

*Update*I have printed off 3 different projects ranging from 6-16 hours each and have only gone through one color change and only just barely with an infill of 30%. If you're looking for a filament that'll give you color changes in one project then this is not the filament for you. The picture they use is extremely misleading and you will not achieve those results. Besides the color change issue, however, the filament does have a great quality and I consistently put out good prints with it. I won't be buying their rainbow filament again unless they shorten the distance between color changes drastically but I will buy their single colored filaments as I am very satisfied with the overall detail and quality of the prints.So far so good on this filament, had to bump my temps up to 215 to keep it flowing properly but it has so far been a smooth print job. Colors are nice and bright as well, though there seems to a massive length of each color so you'd have to print large items to really get the rainbow effect. I'm sure if I'd have done more than 15% infill I would have seen better results, but I cannot complain.Will buy again, highly recommend.

Great quality, worked perfect for my makerbot sketch. I had literally no print problems. The only thing is that the color change is so slow each print rarely saw any rainbow, and it if did it didn’t fully catch both colors. Unless you have a HUGE print, I wouldn’t use this for the rainbow effect. I SINCERELY doubt the bear pictured was printed using this filament, as the filament is not shiny and that color change is probably 6-10 times faster than reality unless you’re using like near 100 percent infill.

Not the worst filament I have of the variety I bought for my first prints on my new ender 3 pro's, but not the best either.Temp: Needs to be on the high end of the range, otherwise, it doesn't print or adhere at all and as a newbie it took a bit to figure out what was going wrong because it was the first "fickle" filament I had.The temp I have to run at ends up with stringing, I can clean that up, but if I lower it even 1 degree to limit that, it has massive adhesion issues. I'd rather clean off the stringing issues, then have a print halfway through just stop sticking and end up ruing the whole print.Color change: does not match the photos, it does match the text of every 15 meters or so, but that's almost a whole print at 12+ hours at 20% infill. If you want more then 1-2 colors if you're lucky and it's a big print) you're going to have to have a heck of a lot of supports, infill, and a long (1+ days print) to hope. You'd have to use roughly 1/2 he spool in one print to get the "rainbow" in the example.Just teaches me to look at the text of how many meters it color changes, rather than look at the photos.
