Swedish Sandvik announces 3D printing of diamond composites

According to foreign media CNET, Sweden’s Sandvik has announced that it has developed a method for manufacturing diamond composites using 3D printing technology. This material can be formed into many custom shapes.

Diamond is one of the hardest substances in the world, and the past 3D printing of diamonds is unimaginable. It is only now beginning to break through this possibility.

Sandvik uses stereo light curing (SLA) technology, which uses a slurry of diamond micropowder and polymer to print and sinter to form a diamond composite that has been tested to maintain the physical properties of the diamond.

Despite these characteristics, 3D printed diamond composites do not retain the luster of natural diamonds, but it does demonstrate how 3D printing is moving from prototyping to real manufacturing. Combined with its powerful technology in additive manufacturing and post-processing, Sandvik will enable people to apply diamonds of any shape to applications that are not yet involved in aerospace, automotive and other applications.

Sandvik claims that 3D printed diamond composites are used in machine tools and will last 10 times longer than silicon carbide and 100 times longer than wear-resistant steel.

At present, Sandvik does not explain the production cost and time to market of the product.
