eSUN 3D 1.75mm PETG Blue Filament 1kg (2.2lb), PETG 3D Printer Filament, 1.75mm Semi-Transparent Blue

Many reviews on here are stating that the filament is very hard to deal with, and they blame the filament for not having adhesion and awful prints.After 3 days of troubleshooting I finally was able to get this filament to stick, however it was not the filaments fault (Though I was ready to return because everything I tried was not working.)Things to troubleshoot1. What slicer program are you using?I had a terrible time with Simplify3D. I recently purchased the program, thinking it would make my prints look beautiful. It did the opposite. After many hours of tweaking, I found the the slicer was spotting the filament and not producing any good results with this filament. I changed to Cura, and Eureka! Was beautiful. However on the 2nd layer the adhesion was awful, ultimately failing the print.2. WATCH YOUR TEMPERATUREThis is huge, I cannot stress this enough that this filament is extremely vulnerable to temperature. A 20 degrees drop in temp, with result in failure, even when the filament says it is ok at that temp. Case and example, I was running 245 - 250 degrees and getting beautiful results. However due to settings in both slicer programs I was using, the temp would drop dramatically to 225-230 degrees. Normally with PLA this would be not a huge deal, however with petg and this filament, it will result is awful adhesion and a print failing. After adjusting the programs to have a stable 250 during prints, a stable adhesive print.3. Research good adhesionDo not try to simply use the buildplate! Your print will not stick, and it will fail. I order a printinz.com buildplate, and it works wonderfully. However I researched many other options including glass, buildtak, painters tape, etc all will work. Find what is best for you!4. STRINGYThis filament is extremely stringy. In most PLA, you can adjust settings and almost eliminate stringing. With this filament, you will have some stringing. However the trade off, is you have a print that is much more flexible, and durable. I can attest to this, as I not only was rough with the print, I drilled through aggressively. There was very little give, and it took time to drill that hole, this is wonderful! PLA would easily cracked, and broke, but this filament holds up! Make your mod parts with this filament, especially if you have an Anet A8 like myself.5. CoolingI ultimately fixed my issue. What had happened for me, is that the nozzle was being cooled drastically. Both slicer programs, were running my nozzle fan at 100% after the first layer. Because I had awesome cooling (due to a mod air duct) the nozzle would drop 20 degrees, destroying adhesion. This threw me off, because after I had fixed the printer to have a stable 245 - 250 degrees, it was still dropping. Please watch your cooling.6. Bed LevelThis is pretty much a given, but you want to make sure your bed is level. Glass, or a buildplate designed to be level, will help extremely. PLA can be ok with out a level bed for the most part, this filament however is a little bit more picky.7. Heated BedI recommend a bed temperature of 80 - 87 degrees. Having an Anet A8, I encountered immediately a wire melting on my heated bed. Because the printer came with a poorly insulated wire, and a loose connector, the bed lost its power. If you have an Anet A8, I recommend buying 14 AWG silicone wires, and soldering them to your heated bed directly. Replace the wires it came with. The temp control wires should be just fine, however soldering them will also help. If you do not have an Anet A8, please just watch your heated plate temp. Again research is your best friend.I love this filament! Once I finally troubleshooted it and figured out how to get it to work. It was beautiful, better than PLA by far. I ordered a second roll, and also a magenta color.Be sure to troubleshoot everything before chalking it up, that the filament is bad. Yes it is very picky to temp, and how it is put down. However the trade off is a much stronger and flexible plastic.

Absolutely love this filament! eSun has been a go to for me many times. First let's get to my settings since I know that is the thing everyone wants to know if they get a new filament, then I'll give my review:Nozzle Temp: 238CBed Temp: 65CSpeed: 40mm/secRetraction: 1.5mm (DirectDrive and All Metal)Surface/Prep: Carbon Borosilicate glass w/Glue StickSo I love printing PETG. It is actually my favorite material and I know many have issues with it but the more you practice the better you get. My PETG work nowadays comes out as nice as my PLA if not better but it is MUCH more durable and heat resistant. I use PETG for anything structural or functional. I would use it for figurines too if I could but small details are just much more restricted due to PETG "stickiness".This filament is for a filament storage system I am making. I had purchased a roll of Inland white PETG because I live local to a MC and could get it fast. However I have not been able to find more in well ovr a month and needed to finish this project so wanted something that would match. I had seen before eSun was the manufacturer that made Inland and I had used eSun before so I assumed it would be the same so I bought Solid Opaque White. I WAS NOT DISAPPOINTED!! This filament got dropped at my door and was on my printer within 5 mins. Knocked out a holder in 7.5 hrs. It prints smooth, almost ZERO stringing, fantastic layer adhesion, and has a sheen finish that is AMAZING!! I do not print fast, I print for best appearance and don't rush. The eSun paperwork said 245C and 85C on the bed for best results. I ignored this and started at my Inland settings. I had to up the temp 3 degrees to get the smoothest print but that is all. If you want to go faster, you'll prolly need more heat but slower = smoother so I'm sticking to it. I print on glue stick and had ZERO issues getting this to stick at 65C and 15 mind after the print finished you start hearing popping and it eventually releases itself. If your right by the printer you will smell the filament a tiny bit but if your weird like me you'll like it!!In conclusion I just have nothing negative to say about this filament. A truely great PETG, strong, smooth, and just what I had hoped for. It matched the Inland I have been using for the first 1/3 of this project but just prints a little nicer, so it is getting me out of a bind!! I have another roll of eSun "Glass Purple" PETG coming in 4 days for another project (Making custom spools). Hope this helps a few of you and Happy Printing.
