This Taulman 910 is strong stuff! Just printed out a few bits to test.

The first thing I printed was a 20 x 20 x 5 box with 20 percent infill. This was extremely light and only had 0.8mm wall thickness. Despite its flimsy looks, it was very strong. The part couldn't be bent or squashed by hand, so I moved to the vice. The vice was able to squash the part with a lot of force, but upon removing the part, it just sprang back into (almost) its original strength.
After giving it a good squashing, I decided to test its impact resistance. I was expecting one hit with a hammer to destroy it, given the low infill of the part - this was not the case! I was smashing the heck out of that thing for multiple hits with the hammer until it eventually gave in and the top layers begun to give way.

I then printed out a longer 5mm thick strip with 100% infill. This was quite flexible, definitely don't want to use this stuff for a frame! But still very strong. The vice did nothing to it along the same axis as the print was made and the hammer didn't do anything, the part just flung itself around the garage. It cuts reasonably easy with a pair of wire cutters, but requires a lot more force than a beetle could deliver.

I also printed a part with some test holes, keeps its dimensions very well, with a 12mm hole fitting a 12mm bearing perfectly with a tight grip.

Impressed with this stuff for sure, I think it'll fit the bill nicely! I'll try to post a stress test video once I have some wheels printed out.
