Today I'm cleaning up and restoring a set of Atco MOTO-CENTERS. These were/are also sold under the name Harig Lectric-Centers. These ones came from an eBay listing and the seller ended up being local to me. We made a deal. I brought them home. And now we get to find out together what I got.

Support Clough42 on Patreon: https://patreon.com/clough42 Today we're going to test a bunch of different 3D printing filaments to see which is the strongest. Are carbon-fiber nylon filaments really as strong as the marketing would have you believe? Or is PLA stronger? Does the addition or carbon fiber make the filament weaker, as many have claimed? We're going to find out today. We'll put PLA, PETG, ABS, PA12-CF, and NylonX to the test. We'll measure deflection under load and ultimate breaking (tensile) strength and see what we can learn.
