PRILINE PETG-1KG 1.75 3D Printer Filament, Dimensional Accuracy +/- 0.03 mm, 1kg Spool, 1.75 mm, Black

I have a Prusa Mk3 which I have pretty well dialed in for PLA. I bought this PETG as my first foray into PETG and I was looking for a plastic that is a bit more flexible without being flimsy like TPU. Using this black Priline PETG my first set of prints didn't go so well. It didn't adhere well and left little globs of plastic on the build plate. I tried the "Generic PET" setting in Prusa's Slic3r Mk3 app and then tried the "Prusa PET" setting and they both looked pretty terrible - there was a weird texture to the printed plastic and it was really globby. I did some reading and I played with a lot of settings, but didn't start to have success with this filament until I noticed that the base layer using the Prusa presets is set to 230C. I raised that to 240C and the print looked much better. Then I went to 245C and things started to look perfect. I tried to 250C and that still looked fine, so I backed it down to 245C and 80C bed temp and it's been great ever since. As other reviewers noted the plastic has a bit of a rough texture, and when printed in thin layers the actual color is a very very dark green - something darker than olive-color. But once I raised the temperature by 15C over the base preset it's printed beautifully and looks as good as PLA with excellent adhesion on the bed, no warping at all (when not using a brim at all), no noticeable odor and prints look very good.

This was very easy to print. I quite literally succeeded on the first try (first time using PETG). I have an anet a8 with a few upgrades (including an enclosure). I experienced no warping on the corners at all. I set the bed temp to 80, extruder at 240, and 25% fan, 0.28mm layer height, 60mm/s speed, 1.2mm wall thickness, 20% fill, and 10 line brim. For bed adhesion I use the metal bed, coated with hairspray. I have seen many different tactics, but to be honest if you want reliable printing, go to your nearest dollar store and buy the cheap, extra strong no scent spray. Its basically just a can of PVA. Being cheap it does not care about your hair and thus works well for printing. I experienced some stringing near small holes, this could be remedied with a slower speed and/or a little more cooling. I will update if I find better settings. Aside from being easy to print, the filament appears to be very strong. Despite the expensive price compared to ABS, its probably worth it. It warps less and smells less bad. As far as tolerances go, it did surprisingly well (given the large layer thickness and high speed), the prints were able to hold a +/- .001 tolerance for a .5in thick piece and a +/-.004 tolerance for a 2 inch thick piece on the XY plane. My Z axis tolerance tends to be worse (usually +0/-.006) and this was in line with that. With this being said, I am an ME student and was very meticulous while building my printer, your mileage will certainly vary.I have received no compensation for this review

This is my first spool of Priline PETG. The filament printed perfectly with my standard PETG setting, that I use for almost all PETGs. Had great bed adhesion, strong layer adhesion and gave me no issues. It was slight stringy, but I was printing hotter then I should, but I was to much in a rush to fine tune anything.The packaging shipped in a typical amazon bubble lined bag. The box had no damage. Inside was a properly vacuumed packed bag with a descant packet inside.I printed at 250ºc hot-end and a bed temp of 75ºC, using a 4.00mm retraction @40mm/sec. My hot end has a 0.3mm nozzle and it worked great at 0.87 multiplier.The prints were perfect, Strong, smooth and functional. The slight stringiness was resolved with a hot air gun on low.

I tried and tried to like this filament, but finally sent it back. It was my first experience with PETG, and it almost was my last. When I first loaded the filament, it *seemed* to print well, but subsequent prints always tended to jam or stutter. If I ran some ABS or PLA through to clear out the nozzle, then again the first print with this filament would work, and again subsequent prints would jam or stutter.Even when the prints seemed to work well, on closer inspection they were not so great - despite trying a variety of combinations for hot end temp, bed temp, print speed, etc., I could not find settings that produced consistent / reliable layer adhesion, and the prints often seemed overly brittle. To be sure it was not a problem with moisture, I baked the filament for 2 hours at 170°F (75°C), but it made no difference.Since I could get beautiful prints using H***b** PLA and ABS filaments, I did not feel the problem was in the machine. I almost gave up on PETG, but decided to try the H***b** version -- and what a difference! Now PETG is a joy to work with, rather than a continual frustration. It may be that I just happened to get a bad roll of the Priline ... YMMV ... but I don't plan to try another.

I've only printer a half-dozen or so items with this filament, but so far it performs very nicely.I'm using a Prusa i3-MK2s using basically the stock Slic3r Prusa Edition setting for PETG.This is the first translucent filament I've used and I'm thinking of making some LED-lit sculptures with it.

This filament started out ok, although it was a bit brittle and has a surface texture that looks like teeth marks from an extruder. It was poorly wound however, and I was afraid it was going to jam but it would always pop free. I printed one object without issue, but started having adhesion issues. I had converted my firmware to UBL with a bed sensor about a week prior and suspected errors from the sensor. I finally regressed the firmware back to the earlier manual method and checked and rechecked, but it would fail shortly into the print with poor adhesion and stringing. After 2 days of working on this I decided to try another brand of filament. A perfect print right off the bat, same gcode file. I have had one other roll of bad filament (another brand) but it at least had the decency to fail right away instead of producing one print and then failing. I'm putting this on my banned list.
