The swedish mechanical engineer sandvik has solved a problem that has existed since the 1950s: synthetic diamonds can only be very bad.
Plastic meets diamond powder
Now the swedes have developed a procedure to produce artificial diamonds by 3d printing, more precisely by stereolithography.
In this case, diamond powder is irradiated in a liquid polymer layer for layer with a uv laser, cured and recently reworked. At this point, sandvik’s manufacturing process differs from the usual stereolithography print.
The ingineure has developed an expensive, proprietary post-processing process. In order to avoid imitators, the transaction first remains a business secret. But much was said: the physical properties of the fake diamond are comparable to those of a real.
Hard and heated
He is very hard, thermal conductive, as well as heat and corrosion. The only drawback is his matte surface. Therefore, he also suits less than jewelry than technical material.
Sandvik’s methods can now create diamonds in almost every shape. The engineer only needs to create the desired shape with a cad software, and the 3d printer superses the rest.
This results in new perspectives for the industry to use the hardest natural material – for example as a tooth drill, as implant, or as a material for precise and wear-bearing tools in mining.
