Abrasiveness

[pciavald]

There is interest in knowing the abrasiveness of a material in order to check and use the right nozzle for the material.

I could not find an existing standard to describe the abrasiveness of a manufacturing material. Based on a few data points I found here and there, I've drafted an initial table of what it could look like:

Index	Filament Abrasiveness	Nozzle Material Recommendation
0 - 5	Non-abrasive	Brass
6 - 10	Slightly abrasive	Hardened steel or stainless steel
11 - 20	Moderately abrasive	Hardened steel or stainless steel
21 - 40	Highly abrasive	Tungsten carbide
41+	Very abrasive	Silicon carbide or ruby
