YOYI YOYI3D Printer Filament,PETG Filament 1.75mm 2.2lbs(1kg) Spool, Dimensional Accuracy +/- 0.03 mm,100% New Raw Material(Blue)

Bought this per my wife's request and she really likes it, great color and strength. If I had a complaint it would be about the packaging that's why the 4 stars and not 5, they ship this in a typical Amazon plastic bag ours didn't fair to well when it was shipped, we just got lucky there was no damage the bag was shredded, so you have been warned what to expect.

I've always used Prusa filament and have never had any problems. Especially with their new in-house Prusament product. The rolls are perfectly wound. The filament NEVER jams. And their colors are great. So why change? They've been seriously hit with over orders and are devoting a lot of their production to PPE for their local market. They will not keep a backorder list for filament the way they do for their machines. I needed over 35 rolls of three different colors for one job that I am doing. I managed to get 10 rolls of the Ultramarine PETG when it was available. Their stock lasted 6 hours.I freaked out over not being able to get a confirmed supply or even answers about when I could get product. Their CSRs are no help at all.Enter this Yoyi filament. I tried it out and found that it worked as well as the Prusa. There are some less good issues: the spools are not perfectly wound like the Prusa; the bags are not re-sealable; the boxes are flimsy if you plan on storing them stacked on a shelf. And the PRICE! Prusa is $26.99 after my discount but before shipping. Shipping is about $5 a roll when I buy 10 rolls or more. Amazon is selling this Yoyi at $35.99!!!!!! Of course that includes free shipping but it is still $4 a roll more expensive than the Prusa.There are cheaper PETG filaments out there but I haven't had good luck with them. The Yoyi has performed flawlessly with maybe a tad more stringing than the Prusa does. The colors for the transparent filaments have been wonderful. I think the red and green are actually nicer than the Prusa. But that is a matter of taste. What is a matter of fact is that the Yoyi is VERY expensive but it is available when the Prusa was not. If you have a project that needs to get done then this may be a solution for you.

They shipped the filament in it's original box which is flimsy. So it arrived busted up and the seal was either broken or just poorly done. I knew it was going to have a lot of moisture so dried it for 8 hours first. Didn't quite get all the moisture out but it doesn't have a nice finish compared to other translucent brands I've used. However, the adhesion with the filament is super. You'll need to use a glue stick or something otherwise your build plate will just become a base for whatever it is you just printed on it. I gave it 3 stars because I'm sure if I give it a few more drying treatments it will improve, but that's not what I paid for.

I've been 3D printing for about three years and currently own and operate three 3D printers and I have extensive experience printing with PLA, PETG, and moderate experience printing with TPU.That being said, I've printed with PETG mostly from eSun, and while their PETG filaments do print well, it takes some moderate experimentation to dial in the proper settings.Not the case with this YOYI filament. Whether it's running through the 0.4 mm nozzles of my BIBO Touch 2 or Flashforge Creator Pro, or the 1 mm nozzle I installed on my JGAurora A5S, this filament has been really stable with minimal dial-in required (though I likely worked out a solid profile in my slicers thanks to dealing with eSun filament)This filament looks awesome when printed. It has a nice balance of translucency, not too clear but this red PETG definitely isn't solid colored like a couple of other spools I have.Normally, I favor 3D Solutech as my supplier of filament, but I'm so impressed with this red PETG I might try some of YOYI's other filaments, in the hopes they're as good as this PETG is.UPDATE: Since the initial posting of this review I've purchased and run through several spools of YOYI's solid white PETG filament. I recently bought six spools for the guitar speaker cabinet that you can see in the photos and to my dismay, five of them had REALLY sloppy filament windings.Much to my great relief, four of the five spools have been run through, and I had ZERO filament feeding issues. While I'm glad there was no trouble caused by the sloppy windings, I hope YOYI sees this and steps up their quality control; This filament is really good stuff and I'd like to continue purchasing it as needed.

No stringing, no discoloration, no smell. Great product. will buy again.

Quick summary: this stuff is great.First off, I do a ton of printing and have tried many different brands and type of filaments. PLA is one of those filaments where even the worst filaments you can still usually make work for rough prints, prototypes, or stuff where looks aren't important, but PETG... not so much. I have tried lots of different PETG's and the bad stuff is essentially unusable, with most of the brands I have tried tending toward the mid-range, which means you can use them but you have to get everything perfect and then watch the prints like a hawk.The Yoyi PETG filaments I have used however have been AMAZING (both the green and the clear). I did essentially zero tweaking on the settings, set it to a good rough guess for PETG, and both printed perfectly. The prints are super strong, I have had zero issues with bed adhesion, and the colors and results look beautiful.Honestly, this stuff prints better than any of the other PETG I have used -- including supposedly better brands that cost half again as much (or more).The only downside on this stuff is stringiness... if you have lots of details on the inside of a part, expect a lot of strings. Reducing the print temp a bit and running the part cooling fan on 50% or less does help, but also reduces layer adhesion somewhat. This is pretty much normal for PETG though (i.e. it still isn't PLA), but PETG is so much better if your part needs a little higher temperature performance and a needs to be less brittle than PLA.

Been using PLA up until now but i thought i would take a crack at this stuff instead. Ive had lots of great results so far and i love the colour and adhesion to the plate and to the other layers. One thing they don't tell you is that the clear green also fluoresces under UV light. Anyway good value and good product

|Awesome filament, After trying this companies PLA and finding that it prints excellent. I said to myself I would try their PETG. I have never had much luck printing PETG and I’ve tried 4 or 5 different brands.This PETG filament arrived today and straight off, first print, excellent. All I done was increase print temperature from 200 to 225, increase be bed temperature from 60 to 70 and change the speed down from 50mm/sec to 40mm/sec.If I can get this good of a print without changing retraction etc, I know I will be able to fine tune it to produce superb prints.Straight out you can see very little stringing, overhangs printed excellent. This model was printed without supports.First thing I will change is the bed temperature for the next print, will set that to 75 as the print was fairly loose to take off at the end.

Never had such bad filament not worth the cost

Great PETG prints great!

Love the colour, prints great
