Thanks for the review Igor! And kudos to bambu for improving their PETG. I hope they release it in more colors like the PETG basic, but this seems like a great replacement.
Glad to see it prints nice out of the box even though Bambu recommends drying first. I actually ordered a couple rolls the moment it hit the global site. Still waiting on mine to show up.
This was a very well-done video. If I remember correctly from Bambu's site, they showed layer adhesion was better with PETG Basic, but it looks like your test showed otherwise. I just received my order of PETG HF yesterday, so I'm curious to try it out after it finishes drying.
Bamboo has a “Dry out before use” statement in the Caution section under the description of this PETG-HF. I wonder if there’d be any difference in your results if it was dried out prior to testing. Thanks for the great video!
Great comparative review as always! Would be great if you could review other High Speed PETG filaments. Elegoo Rapid PETG and eSun ePETG+HS, but there might be more. Elegoo is particularly interesting since it’s ~12€ per kg and available in both EU and US.
As an aside I have had TONS of problems with jams on refill spools. I recently bought 4 PLA Matte refills and 3 of them jammed multiple times. It really felt to me like the problem wasn't the end, but that the spools were not wound with the filament going all the way to the sides, so there were gaps on the left and right that the filament kept getting jammed into.
This is great. Ty so much. Would love to see a test of Elegpo Rapid PETG which I hear generally good things about and can’t find any analytical tests of.
I really loved the PLA Tough and wish now that I had bought a few extra spools. I'll habve to check out your other video on it to see if there is a good replacement.
Absolutely agree on the PLA Tough cancellation compared to the PETG-HF. Did you get early access to the material? I ordered mine within an hour of the release email and am hoping it arrives in the morning. I'm down to 3 rolls of PLA Tough... :( The PLA-Tough is slightly translucent but prints like a dream. I was wondering if they would replace it with something but I haven't seen anything yet, not even a PLA-GF.
I got the spools 2 weeks before promotion (and before my travelling as mentioned in the video). The PLA Tough is "replaced" with PLA basic. They have similar properties (tested in separate video), but I just need that great layer adhesion of Tough. I ordered 5 spools, when I saw that it will be discontinued.
I have a problem with the new filament. It is only recognized for 1 second in the AMS and then it is thrown out again and is unknown. You cannot manually enter the PETG-HF in the slicer because it does not appear on the list (latest version is installed). Only found in the list in the Bambu mobile app
is HF supposed this weak? I printed with 25mms with petg HF and Polylite petg. polylite is way stronger and has amazing layer adhesion, I dried the HF as it was instructed and it's still brittle and has poor layer adhesion
I'm wondering why the PETG reaches lower Energy in the Impact test? Normally it is said that PETG is more Impact resistant and that PLA is more brittle. Do you have an explanation for this?
@@stacki0307 PETG yields more before breaking. It means you'll better get a sense of when it breaks. I don't recLl it ever actually being stronger than PLA in any way at room temperature.
Waking up early to test out filaments? What a guy! I appreciate that level of dedication. Also the vacation scene "thinking" about your deformation tests made me laugh out loud. New subscriber!
@@senurasenaratne5782 I made the same assumption which is where my wisdom comes from....the 50% speed mostly changes the quality of the outer wall and try to avoid grid infill it tends to hate PETG in my experience
I always have the problem of nozzle buildup with PETG or PCTG, does anyone know why this could be happening? Printer is P1S with 0,4mm nozzle and standard slicer settings. K-Ratio tuned to 0,038 and Flow ratio is "standard". In a matter of minutes, a blob forms on the nozzle. This effect is the strongest on the first layers i think but is also happening on all other layers.
I thought that too. But after few weeks I noticed that carboard spools will create a fine powder and that may go into teflon tube casing problems later. I cleaned everything and I am using 3D printed rings
I always thought that HF variants would have worse creep but it's not the case here! Anyway I really wonder why would anyone use PETG on printers like X1/P1/Q1/K1 when ABS prints just as easy and has better properties from every point of view and it is in general cheaper than modified versions of any material. It also prints faster. Habits?
Have you ever printed ABS on an X1C and used a finer setting than 0.2mm, e.g. 0.16, 0.12 or even 0.0.8? Anything less than 0.2 makes totally strange sand dune-like patterns.
For me, PETG allows me to print indoors without worrying about needing ventilation like with ABS. Also, PETG warps way less and there's no shrinkage to compensate for. I'd like to have the setup for ABS/ASA in the future, but for now PETG is ideal for me.
@@jamesmc8055 petg shrinks not much less than ABS. Fumes are also not an issue unless you don't ventilate your room, which if true is a way bigger issue.
@@olafmarzocchi6194 true, all filament does shrink, but so far with Sunlu and Hatchbox PETG I haven't had any dimensional issues. I do ventilate, I have a large air scrubber running in the room, but even that plus a bentobox would sometimes fail to prevent ABS fumes to fill the room. Maybe I'm just very sensitive to ABS.
I am little bit skeptical regarding this test, because on their website there is a table comparing petghf to petg and they say it has a little bit weaker layer adhesion.
@@MyTechFun Ok. Looks like you don't take criticism very well... I really appreciate the stuff you are doing and I like your videos because I see a lot of information from them. I just wanted to point out that just because you printed the filament with the same way, it doesn't mean it was the right way. Maybe the HF filament should be printed with different profile to achieve reference strength values and maybe the basic filament you printed the way that it's not how it should be printed and we get different test results.
@@EEEEMMMMKKKK I get used to criticism, I just feeled that I need to make a small joke on this. I agree about different layer adhesion, sometimes even different 3D printers have different affect. ua-cam.com/video/_pPWvLizjRU/v-deo.htmlsi=k2c0IqGoS9f4IHyB
@@MyTechFun I was thinking about a Pi Zero with camera module pointed at the test pieces and have it capture an image every hour or so. You could then see it deform over time.
I just bought 10 rolls of the HF. I won't be getting more. I go through 30+ rolls of petg per day. If I had to dry every roll before use, I'd never get anything produced. Petg needs to be strong and durable. It's not for priting fast. As far as I can tell, they had a good product with the basic, and someone came up with a really stupid, bad idea, and they went with it. Yay. Now I need to find a new source for good PETG.
Hey mate I'm wondering if you might be able to help me with an Overture PETG profile. Happy to chat over email, if that works too (not sure you can message directly here on YT). Thanks so much

I know you tested before the filament was added to the store so you could do nothing else but your standard left brain engineering tests. However the filament is being touted as being as printable as PLA (speed and quality) with the mechanical benefits of PETG, also that it’s more hydrophilic than normal PETG (so must be dried and kept dry during long prints).

I wouldnt really call an "average" of 2 data points and average, it should really be called a median, as an average would normally imply the kind of distribution typically associated with larger sample sizes.
Stop crying about it and test it for yourself if you need more than what he did. If you call this "UA-cam bait" you should start watching something else, ffs.
I think a major flaw with basically any of this testing is that it really doesn't show the full capabilities of any of the materials. This is due to the print profiles for a lot of these filaments simply being optimised for print quality rather than any kind of strength. It's still good to know how they compare in terms of defaults for the masses, I guess.
Temperature resistance, outdoor use, more water resistant, less creeping on 30-35°C... (try to print something from PLA and PETG and leave it in car on hot summer day)
Your “I cleaned it with isopropyl” comment makes it seem like you think the glue is to help the filament adhere to the bed. They don’t recommend glue for adhesion. They recommend glue as a release agent, to stop it from sticking TOO well to the PEI. One unlucky print without glue and your PEI sheet will be ruined. Just get their liquid glue already. It just rinses off with water afterwards.
More than 5 years I am printing PETG on textured PEI (starting with Prusa MK3). I never used glue on it. And yes, glue will help in some cases with adhesion. Personal experience, I don't care what "they recommend".
@@MyTechFun Next time you print something with a very large, flat surface that is usually difficult to get off the bed, use some glue. It will come off VERY easily. That's the whole point. It isn't to help adhesion. It is to make adhesion worse after the print is finished. It is called a "release agent" in that case. "I've never tried it so I don't need to." is not a good thing to say. You don't learn anything by saying "I already know something." You don't know everything. Just like the rest of us.
Looks like I'm changing all my PETG printing to PETG-HF
You did it again Bambu
First comparative review I've seen on the new HF PETG and it comes from one of my most trusted sources.
Thanks Igor!
Thanks for the video, very interesting that they achieved similar or better mechanical properties in the HF version compared to the basic version!
Good to know they are actually replacing a product with something better!

20C is room temp. And this temp currently I have only in the morning
@@MyTechFun Great content btw (not just this video but your channel as a whole). Thanks.
