Hi,
Can you tell me what this means?
I have a A1 combo, i can’t use the AMS?
Bambu
TPU 95A HF
Cautions for Use
- Dry out before use
- AMS & AMS lite NOT Compatible
It means that Bambu TPU filament is not recommended for use in the AMS and AMS lite. You can still use it with Bambu printers, you just need to feed it from the external spool. Both AMS’s push filmant to the printer and it is difficult to reliably push something that is flexible. The reason it works from the external spool is that the head pulls the filament instead of trying to push it and thus flexible filament is less of a problem.

It works great from the external spool.
TPU 95A is simply too soft to work without issues with either AMS.
The TPU for AMS is built specifically to work with the AMS, it is 68D (less flexible), but, works really well…

That makes sense,
Didn’t use the external spool yet but will figure it out!
Thanks guys
It is really easy.
You will need to manually load and unload, a process you have not likely performed yet with the printer.
The AMS doesn’t require this of you.
When you add the spool to the external spool holder, you will then feed the TPU through the external input.
If you have a P or X series printer, you could benefit from the Bambu 4-in-1 PTFE Adapter which when installed means you can quickly swap between the AMS and external input.
If you have an A series, you will have received a PTFE tube specifically for the external spool in addition to the ones specifically for the AMS Lite.
You may wish to print a PTFE tube remover as the tubes can be hard to remove without one. They are designed to add pressure to the black ring which when pressed will release the grab action that normally keeps it attached.
My process:
- On the printer, tell the external spool to LOAD
- Begin pushing the TPU into the printer using the external access (P & X) or the PTFE tube (A)
- When the hot end is at temp, maintain pressure on the TPU to push it into the hot end.
- Confirm to the printer when you see TPU coming out of the hot end
Done.
To remove it.
- Use the UNLOAD option
- When the hot end is at temperature, pull the filament out, if there is pressure, do not add pressure
- When removed, hook up your AMS again.
Done.

Have you had a chance to test it out yet? I know it isn’t going to be as flexible as 95A but wondering how well it flexes. I’m planning on adding a roll onto whatever my next order is but I’m pretty stocked up on everything right now.
Yeah @MalcTheOracle , I’d like to know if you’ve had a chance to try out the new TPU for AMS
Yes, I have received the 4 of 7 the U.K. got at launch, we still do not have the missing 3 launch colours or a date for their release.
I tried printing a flexible keychsin I designed and available here. It is a brilliantly simple but effective design (oats self on back).
It printed without issue. The design requires the strip be bent over and the two ends touch before a PLA cap is added and a keychain attached. The reason for the detailed description to point out the difference between the TPU 95A and the TPU for AMS. The 95A version bends easily, deforms and snaps back to the original shape. The TPU for AMS doesn’t really come back. It works well, but the noticeable stiffer composition means it if you bend it too much, it retains that new shape.
I printed one of my App icon coasters to see how well it works with multiple colours, stringing and if the edges between colours is sharp enough.
- Multiple colours within each layer - perfect
- String - doesn’t happen
- Edges are sharp - yes, perfect
Something you should note, it’s as fast as BL Basic PLA.
I then decided to push it, can it print my hugely popular Fidget Spinners and Gyros and do they work afterwards.
Something to note, my fidget models have extremely precise mechanics and the tolerances are very tight, the shapes require difficult angles, some close to 60° or more on complex curves. All designed to print without supports. I then have many different profiles to have them print in many patterns.
The two I printed, one Gyro and one spinner worked perfectly, no missed areas, all curves are smooth, all angles achieved. Did they spin. Yes they did, not as easily as PLA, but, that was never going to happen for obvious reasons, but, far better than I imagined they might.
I am very impressed with the filaments, I think this is a whole new filament category and should be considered as such.
It has many if the benefits of flexible but with the performance and ease of use of PLA.
It isn’t TPU 95A, but it is very flexible, how much depends on walls and infill, but, the ability to through it in the AMS, not care about it and just print as easily as you do with PLA is extremely impressive.
You may know I don’t hold back when I think something is bad, but, I am equally enthusiastic about things going well, this is one of those.
I recently bought all the PLA Sparkle and all of the PLA Galaxy, they are almost identical in colours and properties to each other. So much so I’m not sure both should exist.
The PLA for AMS however is a great product. I look forward to the final release of the missing launch colours.
I have ordered all 6 wood colours, I doubt I will be as impressed with them as they promised to include actual wood in the mix, but, there isn’t any information in the product pages or disclosures to say is it fibre or sawdust and the percentages.
In essence that will just be 6 new versions of brown.
Did neither of you see I did actually said it works really well, I wrote that after all the tests I did.

I saw that, but doesn’t mean it was first hand experience. YouTube is full of people claiming things work really well based on their vast experience of seeing other videos of it working well. There is probably videos about how great the new Prusa Core One works based on it simply being a Prusa and they’ve heard they are good machines.
Not that I’m lumping in you in with the type to give a positive review without merit, just that you tend to have problems receiving packages and wasn’t sure if you got your hands on it yet LOL
I am many things, many very bad things, but, I never claim to know something I haven’t used myself.
I would always qualify a response with “some say”, “others said” or more commonly “I haven’t used it, but, I heard”.
Anything else can get me looking very stupid.
I can achieve that without false claims of knowing something,
I saur it! I just wanted detailed information 
You know me, I can throw down some experiences, usually more than most wish to have shared.
But I enjoy the experience, mostly for the knowledge!
