Fun #FDM discovery yesterday. I was printing some clamps for my new CNC, and of course, I wanted the strongest material I could get my hands on. I have Polymax PC to hand, but I could also source some CF or GF nylon (also from Polymaker).
Now, one thing I learned about nylon (from this video here: https://www.youtube.com/watch?v=u8dIpwd6tzo) is that nylon is _so_ hygroscopic that finished prints absorb water and change their properties as they do so. This helped set the context for what I saw.

@3dprinting@techhub.social Luckily, Polymaker have a useful filament property comparison tool: https://app.polymaker.com/ What's most interesting here is that for their nylon range (CF, GF and neither), they show filament properties both when dry _and_ when wet. Given that my workshop is a goddamned swamp, anything I printed out of any nylon that lived there would get water-logged fast. Thus, I compared the 'wet' values to Polymax PC. 2/?
