OVERTURE PETG Filament 1.75mm, 3D Printer Filament, 1kg (2.2lbs), Dimensional Accuracy 99% Probability +/- 0.03 mm, Black (1-Pack)

Overture has been absolutely killing it in the filament game for years now. I love their cardboard spools, I've never gotten a bad batch of filament or even had a knot in a roll. It's perfect every time and it's consistently so much that I actually cringe when I see some other filament on sale and I decide to buy Overture over saving $5 as I know there's far more chance that cheap stuff will not be worth it with jams or getting knotted up when unspooling. This was my first roll of PETG and I was nervous about printing with it. I heard it was much more picky on temps and retractions and adhesion... well either I'm a super lucky guy (which for those who do know me would NOT say that's the case... quite the opposite) or this stuff is just so well formulated but out of the box and just some starting pointers from message boards my first PETG print came out fantastic. No stringing, great bed adhesion to my PEI sheet (and not too much as some say is a problem with PETG) I could go ranting and raving about this product until next tuesday but I'll just cut this off now stating that I'm surprised how reasonably priced this filament is for the quality. I've never used a filament that costed as much as an entry level printer and I probably will never need to if I keep using this stuff. I cannot imagine it's any better. Just costs more.

I picked up this spool of Overture High Speed PETG in Black to mass-produce functional structural brackets and custom machine brackets on my enclosed high-velocity printer. Standard PETG formulas are historically notorious for being slow-printing materials; if you try to push them past 60–80mm/s, they suffer from severe cold under-extrusion, a dull matte finish, and terrible layer separation. This rapid formulation completely eliminates those old constraints, keeping pace with aggressive modern kinematics effortlessly. Why this rapid PETG is an exceptional blend: Legitimate High-Velocity Flow: The melt flow index on this plastic is outstanding. Pushing it on my high-speed machine, it melted rapidly and consistently inside the hotend. I was able to comfortably crank my volumetric flow rates up to 18–20 mm³/s in the slicer, maintaining linear print speeds well past 200mm/s without encountering any extruder clicking, skipping, or gaps in the layer walls. Impeccable Precision Winding: The "neatly wound" claim is 100% accurate. The filament is layered perfectly flat and uniform from the inner core all the way to the outer rim. This meticulous mechanical winding completely removes the risk of overlapping cross-over knots, giving you total peace of mind during long, unattended overnight runs. Low Stringing & Oozing: PETG is famous for being incredibly sticky and leaving spiderweb strings all over a print. This Overture formula pulls away from the nozzle much cleaner than legacy budget alternatives, leaving crisp outer walls and requiring minimal clean-up with a heat gun. Makerspace Setup & Slicer Tuning Tips: A Deep Bake is Mandatory: Even though it arrives beautifully vacuum-sealed, all PETG is highly hygroscopic. To completely eliminate micro-stringing and fine surface bubbling, bake the roll at 65°C for 6 to 8 hours in a dedicated filament dryer before hitting print. My Settings: I achieved pristine, glass-smooth results running a 245°C nozzle temperature, an 80°C bed temperature on a textured PEI sheet, and dropping the part cooling fan down to a maximum of 20% to guarantee the absolute toughest structural bonds. The final verdict: Overture has engineered a top-tier engineering plastic that gives you all the industrial impact resistance of traditional PETG, but completely strips away the slow print speed limitations. It feeds flawlessly, winds perfectly tangle-free onto the spool, and maintains ironclad interlayer toughness under heavy torque. It is a fantastic value buy that has earned a permanent place in my workshop's daily material rotation.

UPDATED REVIEW: Getting this PETG to print was a real struggle for me but... it ended up eventually working so in all fairness I've upped my review stars and I take credit for this as "user error". What it boiled down to was print speed. I was working with common slicer templates for PETG which print around 50mm/sec and I see other people reporting success at that speed but, it was a total mess for me. I found a few reviews that suggested turning the speed way down so I tried it and it made all the difference. I am working with a new Ender 3 v2 Noe with PEI build plate. Using about 240 nozzle and 80 bed. My esteps are calibrated spot on, and my flow calibrated to about about 88 for this material in my machine and these temps. I turned the main print speed down to 30mm/sec and the initial layers, supports, and walls down to 15mm/sec and it completely changed my printing experience with this material. ***HERE IS MY INITIAL REVIEW BEFORE I DISCOVERED SLOWING DOWN THE PRINT SPEED*** Based on other reviews and pictures, it seems some people have had great results with this filament. My expectations are low, I just wanted decent results as my prints are mostly functional and I am not overly concerned with aesthetics. Unfortunately after hours of testing and tuning I have not achieved a single acceptable result and will likely give up with this Overature PETG. The filament arrived sealed, I have stored it in a vacuum bag and use a heated filament holder when printing. My machine is a new E3v2 Neo with capricorn PTFE tube and a bi-metal heat break. I also print in an enclosure. ZERO luck with this roll of PETG. The pictures show two temp towers, the one on the left I printed with TECBEARS PLA and the one on the right with Overature PETG. Yes, PLA is nice to work with and as you can see, the PLA tower printed clean starting with 215 and 180 on the top; all layers were good with just a little stringing at the top cooler levels. Again, I just hoped for acceptable results with the PETG; I started at 245 on the bottom with 85 bed temp and finished at 215 on the top layer. All levels look terrible. My e-steps are tuned perfect, I did several flow tests printing single and double walled cubes which resulted in overflow and an adjusted flow rate of 88 which resulted in good flow test results on the test cubes but still most all prints fail, I barely got this temp tower shown in my pictures to print and as you can see, it is terrible in all regards. I have done a ton of tests for 1st layer adhesion and z-offset, my bed is super level (I use octoprint to visualize) and I've tried a few z-offset adjustments, no love... My last 1st layer tests turned out good and then I go to print and it wont stick, the filament globs up on the print head and smears around. I absolutely must have a brim, or better yet a raft or my print fails on the first layer. Sure, some folks have had good luck although I've put in the time and a lot of effort and I give up; I cannot get this filament to produce a useable print on my E3v2 Neo. I am not the only one reporting these challenges, maybe Overature has quality control issues with their PETG? Maybe I never found the perfect adjustments but I sure tried and I have to move on now, I can't spend my whole life trying to get a filament to produce "OK" results. ***SEE TOP OF REVIEW FOR UPDATED SUCCESS STORY***

This filament prints okay overall, especially when running at lower speeds. At slower settings, extrusion was more consistent and surface quality improved compared to faster prints. However, while using this filament my hotend failed for the second time. I can’t say for certain that the filament caused it, but it’s worth noting that this was the first time I’ve ever had a hotend fail, which raises some concern. Because of that, I’m hesitant to fully recommend it without reservation. If you plan to use this, I’d suggest printing slower and keeping a close eye on temperatures and flow. It may work fine for some setups, but based on my experience, I’m being cautious.

Prints VERY well. I have been using PLA+ for a long time and I have been getting mixed results. A lot of failed prints, ect. I tried this and have not had a bad print ONCE. prints to a very nice quality, very strong. Prints I could snap with my hands made of PLA hold up much better with this PETG. Excellent bed adhesion with a textured bed. Once it cools down the part just lifts off. I haven't needed to vent to the room like with PLA. Sometimes longer printed would smell, no smell with this. (At least nothing that bothers me). Will be using this going forward. Super easy, makes my printer much more useful.
