Rapid 3DShield is well suited for a variety of 3D printable radiation shielding and other high-density applications such as counter weight and anti-vibration and other industrial applications. Rapid 3DShield can be printed on a traditional 3D printer using common hardened steel nozzles. Rapid 3D Shield high density filament uses high quality tungsten to reach these unprecedented levels of density in a 3d printing filament.
