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 fea
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.
After a few stringy, difficult to use PETGs, I’ve been very impressed with this material.
Adheres great with an 85c bed, and prints without excessive stringing at 230c.
You have to print it slow (below 40mms), but if you can be patient, it can give great results.
It has a nice shiny finish at 250 to 260c and layers adhere great. It’s really strong, has a good amount of flex and never comes brittle.
I’ve gone through about 20 rolls of the stuff as I use it for my business, and it’s never let me down. Get some stringing on my ender 3 v2 probably due to retraction settings and the fact it has a Bowden extruder, but none on my Prusa whatsoever.
I open my filament rolls for a week or two sometimes so that it’s ready to be printed, and I’ve never experienced stringing or moisture issues.
Highly recommend! If you aren’t using this PETG, what are you doing!
Edit: not sure how so many of you are having adhesion issues! How about clean your print surface? Prints perfectly on my Prusa with the textured bed.
Of the many PET-G filament I have tried, This has been the most consistent good filament. Have yet to have a bad roll, jams or clogs. As it is PET-G, expect it to be stringy and sticky. It will start to coat your nozzle and heat block over time. So I primarily used the color black to hide imperfections as white PET-G discolors from the heat as it coats the nozzle and releases as a zit. Recommend printing slower than your would with PLA.
Printed successfully with a Hemera extruder assembly and plated copper nozzle in an open air coreXY printer.
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.
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.
As with the white, I’m thoroughly impressed. It has a great sheen to it, prints out very smooth and looks great.
As always, I started with a temp tower and has similar results to the white, so I stuck with the same settings. 240 nozzle first layer, drop down to 230. 80 bed first layer and drop to 70. Print speed 30. Retraction 6.5 and retraction speed 45mm/s. 0% fan first 4 layers and 50% thereafter.
It seemed to string slightly less than the white but again, just brushes away with the finger. The print looks glossy and smooth with all layer adhered together. Printed the grappling hook with no brim, just a skirt to clean the nozzle and with no supports and it came out clean. No sagging and no deformities. The circle centre is solid, with no warping. I think I’m going to be sticking with PETG.
I’m using an Ender 3 Pro with a glass bed and no adhesion.
Prints well on Prusa Mk3s using generic petg settings in Prusa slicer.
Would have been 5* but white was very translucent when I wanted a good solid white and no window in spool to see remaining filament.
After some tuning and finding that this blend prints at a lower temperature than PETG, I settled on 215 Deg C with the fan running as low as it can without stalling on a Prusa Mk3.
This gives me strong prints with just the slightest amount of stringing, I can eliminate this by increasing the cooling, but I want the parts as strong as possible, retraction is also only 0.8 mm.
This filament prints very nicely and consistent, the winding on the spool is perfect all the way to the end and the filament arrived well sealed and dry (Additional drying did not make any difference).
You want to print at a speed that gives a glossy to satin gloss finish, if you get a matt finish, you going too fast or cool.
I bought black and find that this black is nice and opaque which a lot of PETG filaments are not.
Already bought another 2 reels.
I used to try other types of PLA and PETG but since I have started using SUNLU I have found it to be impeccable. No matter what I throw at this filament it just works. Don’t hesitate, because for the price a better filament doesn’t exist and if you do have issues it’s your profile, calibration, bed leveling or whatever, it is most certainly NOT the product. I replaced my hot end setup on my E3 and all of the parts where made with this PETG and not only does it look good it’s like concrete, brilliant stuff.
Never have any issues with SUNLU filaments, and this is no exception
Print quality is top notch as I expected
Colour is slightly lighter than I was expecting. (Bit more Coffee with Cream, than Coffee granules)
Print settings
Bed : 75
Hot end : 220
Z offset : 0.03 (positive number to raise nozzle)
I normally print PETG at 230, but this had an issue with the first layer not sticking to build plate (getting dragged)
packaging states 220 as the high end of the heat range.
With the Z offset I don’t have to worry about the PETG binding to build plate, once bed is cooled to room temp the print just lifts off
This has been a good purchase will defiantly buy more in future. The reason I have given it 4 stars is because I had a little bit of noting/tangle on the first layer, but after getting that undone it has been fine since so probably just a one off.
I bought this filament to print a few items for outdoor use and bits and bobs for my new 3D printer. I got top results and that’s given that I never printed PET before! Excellent filament! Adheres to self perfectly, excellent dimensional accuracy = even extrusion. What more can one want for the price! Excellent! Would certainly buy again.
Printed on a Sidewinder X1, direct extrusion, 5mm retracts.
Bed: 90 degrees (it does like a hotter bed, I tried 80 but it wasn’t perfect)
Nozzle: 250 first layer, 240 thereafte
