I'm sorry, but this test is quite misleading. A boss of mine once took an aircraft speaker housing printed in Ultem, filled it with water an announced it was waterproof. I took the still full housing over to the sink and added one drop of dish detergent, and it immediately got wet all over and started dripping. If your video were to take those printed chambers and spray your leak test soapy water inside the part, where the pressure would drive it into (rather than push it away from) the "wicker basket" of the printed part, you would see a very different behavior: the soap radically reduces the surface tension of the water, and allows it to wet the Onyx; then it will leak air profusely --like an aquarium air stone --at least until the water in the chamber dried up.
"I had no idea what to expect"... proceeds to put 100psi air into the part. You got very lucky. NO ONE SHOULD REPEAT THIS EXPERIMENT! This is NOT safe. Your goggles will not stop a 2" shard of plastic shrapnel from tearing through your neck. The proper way to pressure test something like this is by pumping high pressure water into it, not air, with the test piece submerged in a tank of more water. You can put fluorescent dyes in the water to test for leaks with a blacklight. You can easily and safely test the parts up to a few thousand PSI this way, and actually get useful data by bursting the various samples. And is that a glass jar you're putting it in? Flying glass shards are even worse than flying plastic. I'm rating this an 8 out of 10 on the Louis Slotin scale of scientific testing safety negligence.
Recently bought an Onyx one for my company and we love it so far!

would it be possible to make a 3 liter soda bottle with this material? Would this material be non-toxic?
I wanted to see it with about 50 psi and a little bit of heat, to see what would happen
