Unlocking AM’s potential through materials (Authentise Weekly News-In-Review – #124)

Material sciences are among the most prolific fields of studies within AM, and for good reason. When the technologies for 3D printing begin to crystallize among a selected few, innovative applications mainly spring up from exciting new materials, offering new possibilities. By 3D printing diamonds, for instance, a new shelf of ultra-durable tools can be designed from a terribly hard to shape material. Heightened knowledge of materials’ physical and mechanical properties is giving rise to interesting multi-material applications, enabling complex, functional products to be printed in one go with some surprising features to boot. Still, there is a lot of ground to cover. While we may know the fundamentals of how to print with some materials, we’re still far from a comprehensive understanding of said processes, so researchers will have their hands full for quite some time.

We can now 3D-print diamond material — but not for jewelry

Sandvik, a Swedish company specializing in mining, materials science and metalworking, has developed a way to make diamond composite materials with the 3D-printing technology called additive manufacturing. The material can be formed into many custom shapes, but think of ultradurable drills, not exotic earrings.

Simon Fraser University and Swiss researchers are developing an eco-friendly, 3D printable solution for producing wireless Internet-of-Things (IoT) sensors that can be used and disposed of without contaminating the environment. SFU professor Woo Soo Kim is leading the research team’s discovery involving the use of a wood-derived cellulose material to replace the plastics and polymeric materials currently used in electronics. Additionally, 3D printing can give flexibility to add or embed functions onto 3D shapes or textiles, creating greater functionality.

3D Printed Magnets – Is It Possible to 3D Print Them?

3D printed magnets are attracting attention throughout industry.

Bringing the power of 3D printing to magnet manufacturing is attracting a lot of interest. Magnets are made of critical rare earth metals, such as neodymium, which are in short supply and high demand in the current push for electric cars and alternative energy. 3D printing can help reduce overuse of this material with its ability to create efficiently-shaped and -sized magnets without the time or expense of tooling. This also helps to quickly bring new designs to market. So what’s the hold-up? Beneath the surface, the most powerful permanent magnets have an organized granular structure that’s a challenge to recreate with a 3D print head.
