ATARAXIA ART Flexible PLA Filament 1.75mm, 3D Printer Premium 1Kg/2.2lb Winded Spool 5X Longer Stretch,Easy Than TPU Extruder,89A Shore Hardness,Patent Formula, with Filament Storage Bags, FPLA Brown

I print exclusively in PETG, this goes down somewhere between what I have come to expect of PETG, and how I remember PLA going down. (Added Images to Review. Model is the Satsana Duct for the MicroSwiss hotend setup) Support was from buildplate only, model took very little cleanup as I have come to expect from any decent PETG once dialed in.I print this at between 230c and 235c depending on the part and with 30mm/s wall speeds on a lightly modified Ender 3 V2 and it goes down smoothly. 20mm/s first layer gives great results for me. Stringing is slightly less of a problem than other PETG filaments I have printed with although can still be a problem. I use 25mm/s retraction speed along with linear advance dialed in for my setup.80c on the bed with hairspray both adheres well and releases as I expect with a light sharp tap from a nylon face jewelers' hammer when the bed hits ~60c cooling off. Warping does not seem to be an issue any more than any other PETG I have used. If you get warping, drop your bed temp and use a very light mist of hairspray to help bed adhesion and release.This filament was somewhat picky with retraction settings. I ended up at 4.6mm@25mm/s along with a K-value of 2.2 with the tighter Capricorn tubing although this will vary from setup to setup. .2mm in either direction made a huge difference in stringing, as did attempting to go faster with the retractions.I got this purely because of the color. Options for purple PETG are pretty much non-existent. The color is really close to Pantone 2685C but just a little less saturated. Overall a very nice purple but not quite as deep as I originally expected. Notable, the color does not change over the entire print temp range suggested on the spool as I have seen with another purple filament I tried before.The only thing I wish they would change would be the spool design. Some other spools I have around have cutouts on the side with approximate markers to gauge how much filament is left on the spool. (I now realize this seems to be a master spool, but with no bundled filament options available to refill it with.) This cutout in other spools is immensely helpful in quickly judging whether I can safely start a large print with a spool without having to remove it from the printer to weigh. Not a negative, other spool designs are simply nicer. The vacuum bag is a pretty nice bonus and can easily contain 2x 1KG spools of PETG and holds a seal really well.As long as this stays under $20 a spool I will probably keep buying it. If it goes any higher, I will stick with my go to filaments I stay stocked up on. Pricing has already gone up $1 on here since I bought my single spool 2 weeks ago however I am sure I got it at introductory pricing. I wish this color was available directly from Ataraxia Art, however I can only find it on here with the markup that comes from this platform.TL;DRSettings I can share25mm/s retraction speed (tune distance to your printer)230-235c nozzle30mm/s speed for walls20mm/s first layer~60% part cooling after first few layers to combat stringingIF <$20USD/kg: 5/5 starsIF $20-23USD/kg: 4/5 stars (where I'd consider it too pricey to justify regularly)IF >$23USD/kg: 2/5 stars (this would be too pricey given the filament has no special properties compared to any decent consistent PETG I keep in my personal stock)April 7, 2021 Pricing was $17.49 USD per kg, April 25, 2021 Pricing is now $18.49 USD per KG.

My wife needed some dark brown filament for the outdoor garden-scale railroad trestles she was printing. PETG seems to be the best filament type for outdoor use, so I went looking. It turns out almost nobody produces dark brown PETG filament. I found this filament from Ataraxia Art for $16.99 for a 1 kg spool. At that price, I was quite skeptical, but on the bright side I wasn't out much if it fell flat.Well... I was VERY pleasantly surprised by this filament! The label boldly says bubble-free, tangle-free, clog-free - and that is exactly the experience I had with this filament! It was exquisitely wound, and is a beautifully-uniform looking material, as seen in the photos above. It comes vacuum sealed, and they even provided a separate 2-roll vacuum bag to store it in (designed for use with a vacuum hose).The label says the print range is 200-240 degC. The temperature tower I printed (see photos - tower and bottom) went from 250 to 200 degC. I was able to easily delaminate the tower at 200 and 205 degC, and 210 deg with a fair amount of pressure. At higher temperatures, it was quite solid, no delamination with quite a bit of force. It even printed well at 245-250 degC, which is above Ataraxia's spec'd printing range. Stringing was for the most part very minimal, and might even be improved with a slightly different retraction settings (I used 6mm, 25mm/sec). All of the overhangs printed well, and huge bridges printed well at 235 degC and above. I printed on a glass bed with three layers of hairspray to avoid over-bonding to the glass, which worked beautifully (I did use a brim as this is a TALL tower).If there is a drawback, it's that the dark brown color doesn't sand well, i.e., sanded areas are definitely lighter in color than non-sanded areas. I would guess that's true of most dark-colored filaments, and probably not a fault of this filament.I can't speak to the strength of this PETG compared to other brands as this is my first PETG roll, but I can say it is the STRONGEST (being the only) brown PETG I could find ;-). Seriously, this filament from Ataraxia seems to be a top quality product -- hugely more than I was expecting for the price. I strongly recommend you give Ataraxia PETG filament a try!
