The free shipping option was really fast which was awesome. It also came well packaged in an Amazon box with padding, then in it's own box with details about the temperatures this should be printed at and also vacuum sealed which is awesome because PETG is quite sensitive to moisture.

First off, the orange was a little darker than expecting but is still a nice colour. I used Cura 3.2.1 to slice all my prints and then printed out quite a few benchmarks, tweaked my settings then printed them out again (the pictures are of the tweaked prints), also i'm using a cheap Tevo Tarantula so if you have a more expensive printer expect better quality. The settings I ended up with were:

- Hotend - 235 degrees Celsius
- Bed - 70 degrees Celsius
- Retraction - 4.25 mm and 40 mm/s
- Speeds:
Print 45 mm/s
Infill 35 mm/s
Wall 22 mm/s
- Cooling 85 % (however I think I may have done something weird with my fans so this may actually be 42.5% not too sure)
- Infill 10%

I think this is an interesting material because it is relatively new to the 3D printing market and has a lot of potential as it combines the easy printability of PLA with the toughness and strength of ABS. So overall I think the print quality was pretty good, but it doesn't print as easily as PLA because it can warp without a heated bed and I have found it strings more. It is definitely less brittle than PLA though and it much more heat resistant.

You are going to want to lower all the print speeds especially infill if you want it to be sturdy. Also some people say that having the nozzle further for PETG is good, but I've found when printing on glass you'll want it as close as you would with PLA to get a nice bottom surface finish (reducing the temperature of the nozzle slightly may prevent it from sticking to the nozzle). Bridging also wasn't as good as PLA in my experience, however this may just be down to my print settings.

Whilst I could not directly compare the strength to that of PLA, it defiantly felt sturdy and tough. Overall I think it is a good material, easy enough to print with a few tweaks and can be used for a huge range of applications which PLA isn't suitable for (like mechanical parts, electronic housings, printer upgrades ( due to sturdiness and heat resistance) etc....

I bought three different types of filament made by Sunlu. PLA, TPU and this PETG. So far I've tried the PLA, and it was stringy and gloopy and I had to run it between 170 and 180c which is well under their advised temps, and low for most PLA. It's the same story for this PETG. At 240c it was horrific. It just made a nest of strings, blobs, and couldn't complete an overhang as low as 40 degrees. I had to turn down my hotend to 210c (10c below their stated minimum) just to make the Petsfang Bullseye cooling mod pictured. It took a whole day of calibrating and 200g of filament wasted just to get this result, which as you can see isn't great. At this temp I had to run it suuuuuper slooooow or the extruder would slip because the hotend had to be so cold. As a result it took a whole day and night to pint the two parts of the Bullseye mod, when it should've taken 6 hours tops.

Oh and as you can see, it's not actually black, but a dark redish, and looks greenish on thin layers.

I have Sunlu's TPU left to try and I really don't expect to get much better results. I've had way better results from a much cheaper competitor sold here with Prime delivery.

I wont be buying this again.

I've never used Sunlu PETG before and was surprised how good it was for the price.

I use a Prusa Mk3 with Simplify3D and this White Sunlu PETG dialled in nicely although you need at least 5 solid layers to get some opacity. Dimensional accuracy is good and prints are strong and reasonably clean.

The only negatives I've found are:
1. Its quite a stringy/hairy filament, so you need a bit more retraction.
2. Large prints require monitoring as hairy filament build up on the nozzle can cause tiny burnt black blobs to drip on to your print...not good when using white.

I've since used a couple of reels and will probably buy some more so would recommend.

Used sunlu petg (black) to print 3d printer parts as well as a single big cubic part (~20x20x20cm).
- reel winding: not the tidiest wound filament, but the whole roll unrolled fine.
- stringing/blobbing: average-to-high for a PETG. Printing at 235-240C seemed to produce the cleanest results. Can turn messy really quickly though as it oozes easily (but then again, which PETG doesn't)
- layer adhesion: no issues there, sticks nicely to itself
- bed adhesion: no issues either, printed directly on PEI with bed at 80-85C, held well and separates reasonably easily once cooled down.
- surface finish: nice black gloss, can be dulled a bit by tweaking the temperature/extrusion speed
- does it jam: with a 0.4mm nozzle not a single jam
- is it suitable for accuracy-critical work: I'd say yes for smaller stuff (the 3d printer parts came out just fine)
HOWEVER, when printing big flat parts (>10cm) I observed some lifting/warping. Way better than I'd get with ABS on my setup, but I wouldn't recommend this for bigger precision parts. Maybe if I printed with an enclosure on...?
- smell when printing: no smell noticed

After trying another brand of PETG and failing miserably I decided to try the SUNLU stuff seeing as their PLA+ is my goto filament. So impressed! I'd pretty much decided that PETG wasn't for me but this changed my mind 100%. The box in the picture was pretty much my first print with SUNLU PETG and it came out spot on! Lovely finish to it, no blobbing, even extrusion and good bed ahesion. I used 245 extruder / 85 bed and no cooling on parts in picture. Since then I've printed out other things that had overhangs and required bridging - used same heat settings and part fan @25% - turned out very nicely.

Prints well at first layer 245 and then 240 with bed set to 60, first 3rd of the reel was fine but found after that it was stuck together and kept jamming up on the spool, not been left to get damp, may be just a Friday afternoon reel, have bought another one and if that's the same it's going back, watch this space, but prints really well apart from that
