eSUN PETG 3D Printing Filament 1.75mm, 1KG Spool(2.2 LBS), Solid Black

I've used this filament for quite a while now, the bulk of it I have used to print parts to upgrade my printer. I've had no specific issues with the filament, it seems to print very well on my Prusa MK3S+ and the colour is pretty nice. The only minus point is because the winding on the spool is terrible, it's atrocious, to the point that I've never seen spools from other manufacturers like this. This seems to be a common thing with eSUN filament, every spool I have and have opened has been badly wound...but... Yes, there's a but! The winding, although poor, has thus far just been cosmetic, bad winding is only really an issue if the winding has not gone onto the spool properly, a long as the filament is wound on without coming loose, then it will come off the same way. Generally speaking, when people moan or complain about badly wound spools, it's because of something they've done and not the manufacturer, it's pretty much impossible for the manufacturer to spool filament onto a reel in a manner than it will tangle on the way off the real.

I always buy this brand of filament and never have any issues. Never tangles, prints well, great value and makes nice prints. Highly recommended. I print this on my Creality K1

I purchased the eSUN PETG Filament 1.75mm in Solid Grey as an upgrade from PLA, and while it delivers strong and durable prints, I initially struggled with bed adhesion. Adjusting the Z-axis height helped resolve the issue, and now it prints reliably. ✔️ What I Liked: ✅ Strong and Tough Prints – PETG is far more durable than PLA while still being easy to print with. Ideal for functional parts and mechanical prints. ✅ Consistent Solid Grey Color – The filament has a clean, uniform grey tone that gives prints a sleek, professional look. The surface finish is smooth with a slight sheen. ✅ Good Layer Adhesion – Once the first layer sticks, the prints are strong with no delamination even on larger or taller objects. ✅ Minimal Stringing with Proper Tuning – PETG is known for stringing, but after tweaking retraction and temperature settings, I managed to reduce it significantly. ❌ What Could Be Better: ⚠️ Bed Adhesion Needs Some Work – Compared to PLA, this PETG required extra adjustments to get a good first layer. I had to lower my Z-offset slightly to improve adhesion. Using a glue stick or PEI sheet also helps. ⚠️ Hygroscopic – Needs Dry Storage – Like all PETG, it absorbs moisture quickly. Keeping it in a dry box or using a filament dryer will ensure optimal prints. ⚠️ Higher Print Temps Required – Nozzle needs 230-250°C and the heated bed should be at 70-90°C, which might be tricky for beginners switching from PLA. 💡 Final Verdict: The eSUN PETG Solid Grey filament is an excellent choice for functional, strong prints, but bed adhesion needs tuning. If you're coming from PLA, be ready to adjust your Z-offset or use bed adhesives to prevent prints from lifting. Once dialed in, the results are fantastic! ✔ Best For: Strong, durable prints with a sleek solid grey finish. ❌ Not Ideal For: Beginners expecting PLA-like adhesion without adjustments. 👉 Overall: 4/5 – Reliable PETG filament once tuned, with a great solid grey color!

This was my first ever PETG filament, but as I have been getting amazing results with their PLA+ filament I thought I would try eSuns PETG. I have to say that 1st impressions were not good, I was really struggling to get good results at first, with problems with bad adhesion, blobbing, stringing, layer adhesion etc, however I now know this was all down to my configuration and not the filament. I am using and Ender 3D V2, and Cura as my slicer. After many different attempts I found that downloading eSuns material profile for PETG helped, but after some trial and error I find the optimum print temperature for my printer is 138 (profile default is 145) I guess there is some tolerance in the temperature calibration of different printers. I also found you have to print fine and slow. I have made the following adjustments to the default Cura Dynamic Profile 0.16 layer height 0.2 for 1st layer Build Plate 70 Print Speed 30 Wall, Top/Bottom Speed 15 Initial Layer Speed 15 Number of slower layers 5 Cooling 20 Ironing I also had to get me e steps and bed level spot on, any under extrusion really showed on large flat areas. I use the smooth side of a textured glass build plate, and cote with basic watered down PVA glue, for perfect adhesion when printing, but once cooled the print just falls off with no prizing required. So it took a fair bit of trial and error, but the results are now amazing, with very shiny and smooth top and bottom layers.

A+

I've been using this 1.75mm PETG filament for a few projects lately, and I have to say, it's been a solid performer. The print quality is really impressive; the details come out crisp, and there's a nice shine to the finished products that adds a professional touch.

A couple of tests and the magic numbers became apparent. (Not that they are any secret they are pretty much what is recommended on the box), but just so it can be said to have been done, printer is just an Anet A8, no particular mods, bed is blue painters tape. Bed temp 80c throughout (this was to overcome warping but I feel I will be able to modify this with geometry changes to the items). Extruder temp 240c. Nothing fancy or special but I do find with this type of filament, especially if you are manually levelling the bed is to set that base layer layer very very small, almost having the nozzle scraping the blue tape, but much lower than I would for PLA or ABS. It seems to want to be hard "piped" onto the surface. That being said I'm not needing any stick glues or proprietary adhesion helpers. PETG always (to me) seems somewhat prone to stringing but those settings will be something you fine tune for your own set up. So tl:dr Bed 80c. Extruder 240c. Tight bottom later. Will buy again, consistent, quality product from a manufacturer I have found to be so in the past.

First off in contradiction to some other reviews I am happy to receive cardboard spools for environmental reasons . Yes the cardboard spool was bent by the shrink wrap and other manufacturers manage to provide non bent cardboard spools but it hardly matters to me as did not cause any issues. Printing. I managed to print with this filament fine although I had some stinginess and oozing out the nozzle from first use which likely indicates moisture although this was not excessive. Now colours. See photo of eSun gold chess piece with eSun red and neutral rings and some other red yellow things and a remnant of some other gold filament. Neutral is like bubble wrap which I guess is probably about right. Red yes it’s red but some how it’s just not popping bright red as it could be. A little light in the corners maybe not having enough pigment or maybe I am too , it’s good enough just not impressive. Gold. YeahGold. I would hardly call this gold. At best I would say it’s a better yellow or a ripe lemon colour. Pictured with a remnant of other gold filament and a piece of sweet corn it’s in a clear third place in looking golden. Value for money? How can I rate that when the price is always changing showing discount from a very premium price? I won’t be buying this brand again I was taken in by the supposed discount and the fourth spool I bought but didn’t open will probably be returned.

Prawie nie rozni sie kolorem od zoltego, jest delikatnie ciemniejszy. Pierwszy raz widze jak przy druku filament sie kruszy, caly plate i na okolo drukarki jest w okruchach. Nie trzyma sie stolu, nawet po 40 min druku odkleil sie od stolu.

Pour le prix, c'est correct, avec les bons réglages.
