Basics

A FDM 3D Printer Nozzle made of a Brass Body, with a Polycrystalline Diamond Insert for the Orifice / "Cone" that leads into that
Thus has:
- Higher Thermal Conductivity
- Lower Friction
- And Most Importantly: Is not impacted by Abrasive Filament (Sort of if you are printing diamond reinforced plastic!)
Better than Brass Thermal Performance, Better than Hardened Steel Nozzle / Tungsten Carbide Nozzle Hardness
Main Issue is Cost (Although in comparison to similar hardened nozzles, it is somewhat nominal)
A Bit of an Unknown is Fragility
- Due to both Impact/Shock, and if a Cold Pull (FDM 3D Printing) can be preformed
- It also has a Lead warning, need to determine if this is due to Leaded Brass or Leaded Solder
  - Either way looking into that, and Lead Exposure from FDM 3D Printing (which should be minor, but hard numbers would be nice)

Ruby Nozzle (Same Concept, but Poor Thermal Performance, and Decent Hardness, Also there have been reports of the Insert Becoming Dislodged, hence the fragility concern)
