Sandvik Has Developed 3D Printable Cemented Carbide

Swedish materials manufacturer Sandvik has been developing cemented carbide for the manufacturing industry for several years now. Recently, the company announced that it has been working on a range designed for additive manufacturing. Manufacturers can then 3D print parts that are highly resistant to wear and have a very high hardness, even under extreme thermal conditions. Sandvik thus proposes to offer one of the hardest 3D printing materials on the market, expanding the range of possibilities for users.

If you’re familiar with the company Sandvik, it’s because it has already been the subject of several very interesting material developments for the additive manufacturing market. Indeed, in 2019, it had unveiled a 3D printed diamond composite, a first for the market. This time, it is interested in cemented carbide, a composite made from a hard material and a metal binder. It has excellent electrical and thermal conductivity as well as high hot hardness. As they are particularly hard, their machining is very complex, especially when it comes to obtaining complex geometries. This is why the Swedish company wanted to develop a material compatible with 3D printing, which, as we all know, offers more freedom in terms of design.

What are the characteristics of this cemented carbide?

Sandvik therefore came up with a cemented carbide optimized for powder bed printing processes. Anders Ohlsson, product manager at Sandvik Additive Manufacturing, explains, “The most critical component in our process is to work with powders that have the right properties. Above all, high density brings a whole range of benefits regarding the kind of materials we can produce, and crucially impacts the quality achievable in terms of material properties and geometry. Sandvik has developed both a powder and a process that are unique. With our powders, we can print components that look great, work well, and are fit for use in actual applications and serial production.”
