Why choose a Nylon 12 filament over a Nylon 6 filament? The answer isn't always that obvious as the Nylon 6 filament is often more affordable and also stronger?
PolyMide™ PA12-CF is a carbon fiber reinforced nylon filament with excellent mechanical properties. The benefit of PA12 compared to PA6 is moisture stability. All nylon filaments will change properties from their dry state (which is mandatory for printing) to their wet state.
Its all about moisture intake or how hygroscopic the filament is. The longer polymer chain of Nylon 12 has fewer places for a water molecule to bond to meaning that the results and mechanical properties are less effected by moisture.
This also means you can print and store spools of Nylon 12 for much longer without the worry of moisture spoiling your filament.
