3D PRINTING DAMASCUS-LIKE STEEL

Recreating Damascus steel remains a holy grail of materials science. The exact process and alloys used are long ago lost to time. At best, modern steelworking methods are able to produce a rough visual simulacra of sorts that many still consider to be pretty cool looking. Taking a more serious bent at materials science than your average knifemaker, a group of scientists at the Max Planck institute have been working to create a material with similar properties through 3D printing.


The technology used is based on the laser sintering of metal powders. In this case, the powder consists of a mixture of iron, nickel and titanium. The team found that by varying the exact settings of the laser sintering process on a layer-by-layer basis, they could create different microstructures throughout a single part. This allows the creation of parts that are ductile, while remaining hard enough to be sharpened – a property which is useful in edged weapons like swords.


While the process is nothing like that used by smiths in Damascus working with Wootz steel, the general idea of a metal material with varying properties throughout remains the same.
