Anyone tried the new AMS TPU yet?

Also, agree that the TPU for AMS is super hard for a TPU but it is perfect for parts that need to be reasonably rigid but can take a bashing. Survived a 40mk/h crash into a pole with no cracks :slight_smile:

I am currently print with the “TPU for AMS”. I was quite excited about it; I love printing with TPU, but it was quite the hassle switching the rolls manually once used to the AMS.

But the roll appears have split in the AMS? I was notified of a “failure to feed” and when I investigated I found the side of the spool was loose?

I am waiting for the print to finish. I am babysitting it to make sure it doesn’t bind up again.

Has anyone seen a spool fail like this before?

No.

It would normally mean you didn’t lock the reusable spool together to get the latch point engaged.

Given the TPU for AMS comes on spools and you cannot buy it as refills, you couldn’t possibly of made that mistake as you didn’t add it to the spool.

I haven’t experienced this on any other type of BL material either and I have tried most of them.

I would suggest creating a ticket, providing a photo of it in the AMS and demanding a replacement.

You could possibly recover from it if you have some wide take (brown packaging tape for example). When your print has completed, try the following.

  • Take photos
  • Do not remove the spool yet
  • Remove the filament in the tube
  • Add the tape as far to the edges as possible in long strips sufficient to apply without screwing up or removing the spool
  • Rotate the spool and attach more tape to the exposed area
  • When you have tape wrapped around the whole filament portion, wrap it again.
  • Remove the spool with both hands, one on each side maintaining pressure to the centre of the spool
  • When the spool is in the air, making sure the two halves are flush against each other, try rotating one side (right is best bet) clockwise (away from you) in the hopes it will click into place in the notch
  • If you here the click or feel it lock into place, try adding a gentle turn backwards, sufficient to know it is locked and not enough to unlock it

If that works and you are confident it is now locked, you may remove the tape.

Forgiving the extremely disappointing unlocked spool. I really like the material and enjoy printing with it.

Thanks, Malc. I will try that.

I might be able to respool it, but I don’t think it is usable in its current state. The filament is taking over the inside of the AMS… I can wiggle the side of the spool, so I know it is loose.

I really love this filament, it has quickly become my favorite filament and I want to print most things in it. It is just so durable!

I tried it with some parts that I find it better to be sturdy.
Note that I printed with higher than default temperature to achieve better layer adhesion. I noticed that this actually won’t affect the overhang performance too much.

  1. A cap that is used to hold a gear down in AMS hub
    Prints fine, feels firm, probably can replace the one that I’m using right now with PETGCF.
  2. A couple funnels. It works really well especially to fit different containers that I use for silica gel beads. I printed in vase mode and 0.8mm line width, quite happy with the result.

I purchased the AMS TPU. I find it is about perfect for stuff that needs to be a bit stiff but also grips. For instance, I made a set of soft jaws for my vise. I also used it for the smallest jaws of a printed fractal vise (D jaw).

It isn’t really “soft”, but it works great for things like table pads, vise jaws, etc.
