SUNLU PETG 3D Printer Filament, Strong PETG 3D Printer Filament 1.75mm, Neatly Wound 3D Printing Filament Suit for Most FDM 3D Printers, Dimensional Accuracy ±0.02mm, 1KG Spool(2.2LB), Blue

Sticks to the bed, prints well. Only issue is that when I ran out there was no stock on amazon! Otherwise this would be my go-to petg

REALLY struggling with this filament. My ender 3v2 prints as fast as my ratrig vcore 3.1. My rat rig has a rapido hot end with a bondtech CHT volcano nozzle. My normal brand didn't have any black so I went with sunlu. My normal maximum flow rate in super slicer is 33mm3. With this filament at 260c, it is 16mm3 before my orbiter 2 skips. I thought it was a nozzle so I fitted a brand new nozzle. Nope. Same issue. Cannot extrude this at all. Printing slowly, parts look good. But for rapid prototyping, this filament is no good.

Fantastic filament, works no flawes in my p1p

Prints as well as any other PETG filament as long as your settings are ok - for a very attractive price.If I was nit-picking I'd say it's a bit more translucent than some others when printing thin walls/layers, but no big deal really. Will certainly be buying more of this.

Perfect

Firstly, I bought this filament with my own money and did NOT use the offer of free filament for 5* reviews.This was my first time using Sunlu as a brand and also first time using PETG.Once I'd set the correct layer height on my printer I chose the codes I needed for the parts to build a Lack enclosure and it's been printing ever since. 4 days non stop and I've not had a single issue. The orange is a bit dull compared to the orange on my printer, but that's just picking flies.Make sure to clean your build plate with good quality IPA (isopropyl alcohol) to get good adhesion and you'll be fine.The pictures show the various bits I've printed for the Lack enclosure for a Prusa mk3S.Quick update. I've since used the black PETG which I was told can be a right pain to print with. I can honestly say I've not had a single issue. I just heat the nozzle and bed, select the code and press print. If you can't get it to print, check your printer settings and maybe try a PID tune. Search YouTube for Dr Vax PID tune and sort out the settings on your printer. Makes a huge difference.

Good quality produces good prints. In Cura I use the eSun material profile and it works well but be warned it really sticks to the print bed, I have a magnetic PEI bed and have to carefully scrape off the skirt which is no mean feat

Slicer settings, when you get them right this PETG filament prints ok. Get them wrong, say like normal PLA and it wont stick to the bed, will string and blob. I suggest 240C and a heated print bed of 70C, slow down the print speed, turn off the cooling fan, the travel speed should be max however and turn off retractions but experiment with this. PETG is as strong as PLA but the clear one wont be totally transparent, more cloudy like a net curtain and you can see the layer lines. In theory the filament is food safe so you can make interesting mugs (for cold drinks) and vases for plants, just be careful to not have any unintentional holes.
