Tungsten is a rare material that when carburized can be hard to machine but is more resistant to the deleterious effects of the granular additives of abrasive filaments. It's also more energy conductive than steel, allowing printed material to be primed much more quickly, meaning that print times can be decrease as material extrudes more quickly.
