The technology behind the boron carbide filament from Rapid 3D Shield is designed to provide an easy and efficient printing experience. Compatible with any open-architecture 3D printer, this filament allows the creation of metal objects without the need for complex processes like sintering. To optimize performance, it is recommended to use a Filawarmer and a 0.6mm hardened steel nozzle, which improves material flow and durability during the printing process.

This filament contains 56% boron carbide (B4C), with a printing density of 1.49 g/cc, making it denser than any other B4C thermoplastic compound available on the market today. Additionally, it is resistant to radiation and absorbs neutrons, making it a unique option for scientific and research applications. It is less hygroscopic than traditional PLA, which improves printing stability and reduces moisture absorption. In fact, it is recommended not to dry this filament as it may have adverse effects.

Boron carbide (B4C) is a covalent ceramic composed of boron and carbon, and it is one of the hardest materials known, surpassed only by cubic boron nitride and diamond. With a hardness of 9.3 on the Mohs scale, its ideal chemical formula is B12C3, although it is generally referred to as B4C. This material was first synthesized in 1899 by Henri Moissan through the reduction of boron oxide with carbon or magnesium in an electric arc furnace.

Boron carbide is used in various industrial applications, such as abrasives, refractory materials, and as a neutron absorber in nuclear power plants. Its extraordinary hardness and durability make it indispensable in military and defense applications, such as the manufacturing of armor plates for vehicle protection and body armor. Additionally, it is a submicronic high-purity material, making it the preferred option for applications requiring materials with high resistance and exceptional durability.

In summary, the boron carbide filament from Rapid 3D Shield is an excellent option for those looking to innovate in the creation of metal parts and advanced prototypes. With its easy handling, high compatibility, and unique properties such as radiation resistance and neutron absorption, it opens up a world of possibilities for the manufacturing of specialized parts, without compromising quality or precision. With the backing of The Virtual Foundry and the collaboration of Vulcan GMS, you can be assured that you are getting a high-quality material for your 3D projects.
