PLA is OBSOLETE...

Thank you for watching.

Do you think that the reign of the almighty PLA has come to an end? or do you think that it will never be dethroned...

You are able to find PETG HF here (affiliate):

Such a strange video what are you asking and answering here? Is PETGHF a better beginner filament than PLA (as in ease to print) or are you asking if it has better mechanical properties. What you're actually doing is just passing off misinformation and here's why PLA has better strength, stiffness (snapping rather then bending), layer strength, layer adhesion than PETG HF and PETG HF is sacrificing a lot of Toughness (compared to PETG) to get its higher speed and this isn't me saying that this is backed up with numbers on there site (bambu). So basically you're not actually adding anything new to the discussion at all. PETG was already established as having better heat deflection, less creep over time, and better UV resistance. So you snapping a print at the beginning and giving misinformation well it is just outright wrong and helps nobody. THIS IS BEFORE WE TALK ABOUT ALL THE DIFFERENT VARIENTS OF PLA and how they change their mechanical properties. If you're saying they have made PETG easier to print for beginners then sure I'm ok with that and I would have supported this video. BUT YOU DIDN'T you fell into the old trap of this material is better than that. At the end of the day, it depends on what you want the material for and what you want it to do. PLEASE PLEASE stop doing this it helps no one and is actually misinformation of the material physics. What your actually saying is FOR MY NEEDS i prefer the mechanical properties of PETGHF over regular ok great worth a video probably not but free speech and all go for it!!!

It doesnt matter what form of petg they make, petg is still significantly more toxic than PLA and therefore should be avoided on principle unless you actually need to print something with it.

I do think you underestimate PLA a bit. For 8 years I have had a PLA dog sitting in my car hanging from a suction cup on the window and it has lasted through 4 vehicles. On top of that it has endured 4 heat waves at 110 degrees outdoors while the car sat in direct sunlight. That being said, I do not think PLA is the best. I have only used it a lot because its inherent stiffness and cost. The material is inherently gummy and is semi decent for single use self tapping screws. The biggest problem is what you are saying that it snaps easy under pressure and warps in the chamber. Now PETG HF, the main thing that was holding me back was the price. HOWEVER, just recently I found ELEGOO sells rolls of PETG HF for 11 dollars a roll, cheaper than their 12 dollars a roll pla. Ill tell you, PETG HF is actually an insane material. LONG gone are the days of nasty stringing from petg, and also it tends to not be overly flexible like normal PETG. The HF name is really a dumb choice to name the PETG because in no way have I noticed a difference in flow rate but I will say that stuff literally is a direct replacement for PLA. Its just leagues better.

You'll be obsolete before PLA does 😂

I left PLA after 2 prints basically in the dust, I print a ton of stuff for outside and PLA does not cut it in this scenario so I switched over, sure it was different but it is not that hard even to print with standard PETG, the biggest problem was to get the speed and retraction and distance right, those 3 parameters are actually different to PLA and a little bit of trial and error and research to get right, but once you have everything dialed in, PETG is a walk in the park!

[OutsiderDreams]

Every material has its use case.
Don't use wood where steel is a better option.
Some parts are best printed in PLA whilebothers are better printed in PETG.

Maybe a followup video would be good describing when to use PLA and when to use PETG?

[rsilvers]

PLA is much stronger and PLA plus is much more impact resistant. PETG is flexible and hard to use for mechanical parts.

PLA’s weakness is the heat issue.

[Otamatone_Productions]

I have a 3D printed model garden that uses PLA, they hold up fine, also I use PLA for my animatronic gears and they are stronger than PETG from experience.

[ScytheNoire]

PETG is still not a good filament to use outside, it has lower temperature resistance and isn't UV resistant. For car parts you want ASA or PA.
PETG HF isn't replacing anything, it's just PETG with additives to make it less pure and more of a hybrid.

[christopherbrummet]

PETG is catching up fast with use/variety, and I definitely like printing in it as much as PLA...but they're even better together. Supports using either is fantastic for supporting overhangs. :D

[ELCrisler]

I have been using a PLA printed GPU support bracket in a Gaming PC that is used a lot. People told me it would not hold up but it is doing just fine a year later with no warping.

[wilsistermans]

PLA can still be an very good option. Mechanical properties are quite good and up to about 70 degrees Celsius it will not get soft. If you print at the right temperature (bit at the high side) layer adhesion is pretty good and printed in the right orientation parts are very strong.
Speed comes with an downside. The high flow PLA contains additives (often glycerine) to make it melt quicker. The result is a lower melting point and printed objects are less strong. PLA can be great for outside use, but colours will fade and in the cold it may become brittle (depending on the brand). In a hot car PLA (not the high flow variants) will do fine.
PETG is a kind of all purpose material. Wear and tear in moving parts is a bit less compared to PLA. For use outside PETG is certainly a good choice, often better as PLA. PLA is the most environment friendly plastic, as it is the only compostable (industrial) plastic. Even if it ends in landfill, it will compose eventually.

[jburnash]

thanks. interesting commentary 🙂. I especially loved " I'm not famous".

[qwertyzxaszc]

Yep, that's what i've been using or quite a while now. great all purpose filament. Prints pretty easy and make life easy on yourself and use hair spray instead of glue sticks. Elegoo makes great HS PETG and have no issues whatsoever.

I have long been an advocate of PETG, especially for kid toys like light sabers and the like, because in my opinion it has more "give" or flex for rough play which I think you demonstrated very well. I was not a huge fan of Bambu Lab's original PETG Basic because it did have some difficulties printing compared other vendor PETG offerings (big fan of GIANTARM PETG, especially their metal like silver) and the color options were just OK.

I was all super psyched when Bambu Lab announced the High Flow version until I noticed 2 things. #1 is the limited color options you noted. I swear in the last week or so they just added orange (not in time for Halloween printing sadly 🙂), so hopefully this is changing.

#2 it feels like a step down in capability compared to their old PETG and also PLA by their own product listing page. It is ~same strength as their old PETG, stiffer than their old PETG (which depending on the application isn't necessarily a good thing from the way i am reading it.), ~same layer strength as their old PETG, worse layer adhesion, significantly less "tough" compared to the old PETG, etc.

I have 2 rolls myself, the obligatory black and their forest green (which I was stoked about as no one else seems to make a forest green PETG let alone have it be high speed). I hope my actual testing of the product will show something the raw numbers don't show, and who knows I may dump all my other PETG for this (not the Bambu Lab Translucent PETG though as that stuff is awesome).

I hope you do more videos on your journey with BL PETG HF, and if you do I will be sure to watch every one. 🙂

Happy PETG printing!

[pavelperina]

No. PLA is way better at printing overhangs or bridges and let's face it, for 60-80% of prints special properties do not matter as they will never go outside to scorching sun. I mean various decorations, drawer organizers/inserts. Yes, I can name more things where PETG is better due to flexibility and heat resistance, but for some of these applications it's not the best material anyways.
Plus some material - and from local facebook group PETGHF includes - ease of print comes to need of drying filaments and here PETGHF seems worse than regular PETG.

[donjohnsondprints]

plz is not obsolete just saying but i get what you mean

[cedarcoombs]

Its the same price when compared to Bambu Lab's PLA. You can easily get PLA for less than 15 dollars now.

[rogelioenns]

I use pla for prototyping. It's cheap and easy to print. And since it's a prototype the mechanical properties don't matter. For the final product I mostly use asa. It's uv resistant, heat resistant, and it's lightweight (which is important for me since I print a lot of plane parts). I made a heated enclosure and it is difficult to print so it definitely is not for beginners. Don't know how heavy petg hf is but the normal kind is too heavy for big plane parts
I just checked the prices on the Bambu website and it looks like single rolls are more expensive than pla, but bulk orders are very affordable (8+ rolls). Am considering doing that for prototyping

[joescalon]

Wonder what they are putting in their PETG-HF and how much is messes with the normal properties. Any decent PETG like that from greengate is already high flow, it’s just cheap white label stuff from aliexpress or drop shipped that suffers from low flow rate.
