The "RAPID + TCT2019" exhibition, held in Detroit, Michigan, from May 20-23, is one of the most influential events in the field of additive manufacturing. Swedish advanced product maker Sandvik has revolutionized people's imagination with the world's first 3D printed diamond composite.
It is reported that Sandvik uses stereo light curing (SLA) technology, which uses a paste consisting of diamond powder and polymer to print and sinter to solidify the diamond composite material. This material has been tested to maintain the physical properties of diamond.
"In the past, 3D printed diamonds were unimaginable. Even now, we are only just beginning to grasp the possibilities and applications brought by this breakthrough," said AndersOhlsson, the delivery manager of Sandvik Additive Manufacturing Company. In materials that are three times harder, thermal conductivity higher than copper, thermal expansion coefficient close to Invar alloy, and density close to aluminum, what else is possible for 3D printing of complex shapes. "The Sandvik additive team saw its cash in aviation Kangtian and automotive and other cash The potential of the field, "These benefits lead us to believe that in the next few years, you will see the application of diamond composites in new advanced industrial applications ranging from worn parts to space programs."
Despite these characteristics, 3D printed diamond composites cannot maintain the luster of natural diamonds, and duplicating diamonds with fakes is not as simple as described in the movie. It is still a challenge. However, when Sandvik's strengths in material technology, especially in the application of superhard materials, combined with its strong technology in additive manufacturing and post-processing, will enable people to use shapes never imagined in applications that have never been imagined Diamond.
