Filamet™ is currently in use in these industries:
This drill bit is used to drill through ice in the Antarctic for the IceCube Neutrino Observatory at the South Pole. It's about 4lbs of copper.
Hot water is run through the bit to melt the ice, rather than cutting like a normal drill bit. It has internal structure for managing water flow which makes it extremely difficult to machine or cast, but pretty easy to 3D print - at a quarter of the cost.
This is a 3D print of a bottle with lid used for transporting radioactive medicine it is equal (or very close to) the density of pure lead.
This print is about 94% metal by mass. It's made with tungsten, which is 1.6 times heavier than lead. The whole point of this product is weight, to make the heaviest filament humanly possible. It will be used mostly in radiation management, vibration control and counterweights, marketed under a brand name that already has traction as an injection moldable, super high mass material.
This print weighs about a half pound. The container is 8.4cm high without the lid and 8.7cm with it. The outer diameter measures 4cm.
