TPE Flexible Filament: Robot applications

[seg9585]

I've been experimenting with different types of filaments in my Replicator 2.

We've all made use of PLA/ABS on our robots for various parts, and I've tested use of 3D printed nylon for drive belts and other bendable applications.

I recently came across and just started working with TPE filament (thermoplastic elastomer). It's effectively a VERY flexible filament -- just about equivalent to rubber. It can be stretched easily in any direction and always returns to its original form, while the layers seem to bond pretty well.
Seems to work on the Rep2 after a few mods and special slicing settings.

Here's an example of a print I made from this weekend:

(Pic 2 -- squeezing the part)


Has anyone found a good robot application for TPE filament? Seems like it would be great for custom-fitted padding, or even act as a damper or spring to protect a hard stop. Obviously it makes a fantastic iPhone case... but what other robot related ideas are out there?
