Taulman's Black Alloy 910 filament is designed to be extremely strong without any composite fillers. The intention behind it was to make "The perfect filament for high-performance 3D printing". It is a high quality filament that is easy to print with, making it ideal for applications such as industrial parts and robotics.
According to Taulman, the material has "A combined tensile strength higher than the strongest co-polyesters, the durability of Nylons, a shrink factor that rivals Taulman's T-Glase, a vast range of chemical resistance, and a 95°C working range." At the same time it is designed to be used with ease and printable at 250°C. Having no fillers means that this filament is a pure plastic that is very versatile, but doesn't need any special treatment or skill.
