I would not assume that “product optimization” means that the new PETG (if any)
will be any better, or even as good, as the present PETG. It may just mean that they are reducing product offerings, or switching to a cheaper supplier for “optimal” profit. Tried to buy a black textured PEI plate lately? Or a Cool plate? Or a stainless 0.4 nozzle?
All we know is that the current product will no longer be available.
A few people (comparatively) having issues doesn’t negate the majority of people not having issues.
The fact you say you are shocked they released it like that should tell you something, something isn’t right with your printer, method or filament. The default profile works perfectly well for the majority of people. Remember that forums are biased because people tend not to post about things that are going well as much as they post about things not going well.
Something being wrong with all 9 rolls is unlikely unless you got extremely unlucky.
Better is always subjective, better for us or better for bambu makes little difference, it is still better or they would just keep the current products. It makes no sense for bambu to stop offering a standard PETG.
The black textured PEI plate had issues, it has been replaced by the gold textured plate which performs better and is more durable.
The cool plate was a good idea but ultimately not that useful either, you can use the new smooth PEI plate with or without glue for PLA.
There is little reason to use a stainless steel nozzle over a hardened one. Copper or brass nozzles are better and can make a considerable difference to thermal conductivity but the difference between stainless and hardened steel is pretty small.
So all your examples have been replaced by better products or have been removed because they weren’t that good or didn’t make much sense. It’s not like they have discontinued something and left you with no options or alternatives.
I guess I’m one of the few that wasn’t really happy with Bambu PETG. Printed fine but stuck too well to the PEI sheet and took a while to let the sheet cool to remove a part. Even then, the bottom surface was often discolored and needed a torch to remove the white residue. Printing primarily in PETG, I never had this issue with any other filament. Personally, I use a lot of Eryone PETG and at $12 a roll, it suits my needs fine. Looking forward to see what Bambu comes out with though and if they keep the pricing down around $14 for bulk sale refills, that will definitely sway me to try it again.
Ian does the AMS give an accurate representation of the remaining filament?
Of all the filament I have from BL, PETG is the only one that gives issue. I can print ABS as easy as PLA. Throw PETG in and it’s a tough print. I can use it, but I’d rather not, and I have a bit of it to go through.
I hate adding a “Me Too!” comment about BL PETG Basic but, it has caused a myriad of problems for me. I have chased the problem in my older X1 C to the point of buying New one this month. Turns out that the new printer has the same problem with the PETG as the old printer. In particularly when printing large flat prints with cross hatch [rectilinear] or triangle internal Sparse infill. Printed 2 identical cups. Both with fresh PETG. One on my A1 mini and the other on the new X1 C.
One other point of interest. I have been having difficulty with the lidar both my old and new X1 Cs. One of the new errors on the new X1 C claimed the filament was not reflective enough to allow “Dynamic Calibration” during the print. It turned out to be a florescent light on my old drafting table that I was using to monitor the print progress was putting too much light on the print. So too much ambient light on the plate causes Lidar failure? Turned off the light problem resolved.
Mystery solved,
Hello Josh,Thank you for contacting Bambu Lab support. My name is Rick, and I will be assisting you.I’m sorry to hear that our product isn’t meeting your expectations. We’re committed to providing you with the best possible support and solving your problem.We will be selling PET-G in the future. The current batch of filament is being discontinued and improved with a newer formulation of PET-G. The colouring should remain the same. Unfortunately, I do not have a release date for the new filament, however I do not think it will be too far away.If you require a refund, you must return the filament, and you will be responsible for the return shipping cost. A refund or credit to your account could then be issued.Please let me know how you would like to proceed.I look forward to your response.
Kind Regards
Rick

Not sure how to add the screenshot of the reply… says i cant imbed media items?
Hi,
We need to order a bunch of the PETG Orange for a big summer project, how long until the new filament is ready and to be clear we have a lot of prints we need so I hope it is not something that is a month or two away?
Thank you.
Steve
They are simply updating the recipe to create what they believe is an improved version of PETG. And most of the time, it is.
Extrudr has matte petg too:
I havn’t tried it yet, but I love all the other extudr filaments: Great quality in general and they have material profiles for most popular printers on thier website.
Just got tow rolls of elegoo rapid PETG and Holly Molly, I can do ludicrous mode now (video):
I might need to speed it up a tad, sheeesh.
Should’ve known it was sus that it printed clean @ 300mm/s
One might assume that but given Bambu’s behavior, I highly doubt that is what’s behind this.
My interpretation of Bambu’s announcement is that they are spin-doctoring a BS story. In other words, “Why tell the truth when a lie is so much more believable?” The truth is probably a lot simpler and has very little to do with “product improvement.”
Here’s an alternate theory that I think more fits both Bambu’s behavior and recent reports of their filament quality changing mid stream.
I believe that the evidence points more to Bambu struggling with keeping their supply chain intact that their spin-doctoring a story about “improving” their product.
Let’s be candid, there are enough posts here and enough accounts of similar experiences to build up an explanation based on the existing facts.
Look out for the other shoe to drop. The message might take on such BS marketing buzzwords like “reformulated.”, “New and Improved”, “Special Blend” or more likely, Bambu will make up a nonsensical term that they can copyright or trademark. They certainly wouldn’t be the first or the last marketer to gaslight a consumer base.
Are you running the revo hotend on your bambu? If so, do you like it?
I absolutely love it. Worked out of the box. Didn’t have to do any settings changes. Extrudes a bit faster now and no longer have to disconnect wires and screws to swap nozzles. I hated doing that before because the connectors seemed fragile enough to worry me of breaking them off at some point. Only thing out of the box was that for some reason E3D decided to make the wire lengths extremely short. Like at first it really looked like the wires didn’t reach. But you just really have to bend them efficiently and make sure you route them perfectly for them to reach. That might have been just my a problem with my unit and not that all of them come like that.
That may also be a theory, and it’s a solid one! Time will tell!
I have no problem believing that Bambu’s reformulated PETG will likely be better. Why? Because as already reported on a different thread, Elegoo’s Rapid PETG has an unbelievably high flow rate. A number of people reported 24mm^3/sec, which got me interested in trying it, and I replicated their finding and also found that with black I could get 30mm^3/sec:
That’s even higher than I ever got with PLA. PETG with a higher flow rate than PLA?
That was never, ever true before. Yet, all this at a rock bottom price.
Back in the day, the maximum flow rate for PETG through a v6 hotend was thought to be about 8mm^/sec, So how is this even possible? Is it truly PETG and not something else masquerading as PETG? If so, it would seem some kind of additive breakthrough or other breakthrough has fairly recently happened in PETG filament formulation. Whatever it is, people like it. Just read the reviews and see.
This is indeed noteworthy!!! I missed that in that thread. I just ordered a spool. at $13/spool, it brings it in parity of what I am paying for both PLA and PC. Why would one use PLA if PETG can be had for that price. It also looks like they aren’t playing the typical games we see with filament colors. They are all priced the same.
Here’s the Amazon link if anyone is interested.

Only one thing that I hope is just a typo in the ad. They cite the material as PLA. I sure hope this isn’t some kind of Gamesmanship they are playing and calling PLA a new name “Rapid PETG”
We’ll find out. I’ll run some strength, heat and weight tests over the next week or so.
