Resumen
The objective of this experimental work was to examine and characterise the route for
obtaining demonstrative temporary biodegradable personalised implants from the Mg alloy Mg10Zn-0.5Zr-0.8Ca (wt.%). This studied Mg alloy was obtained in its powder state using the mechanical

The objective of this experimental work was to examine and characterise the route for
obtaining demonstrative temporary biodegradable personalised implants from the Mg alloy Mg10Zn-0.5Zr-0.8Ca (wt.%). This studied Mg alloy was obtained in its powder state using the mechanical
alloying method, with shape and size characteristics suitable for ensuing 3D additive manufacturing
using the SLM (selective laser melting) procedure. The SLM procedure was applied to various
processing parameters. All obtained samples were characterised microstructurally (using XRD—Xray diffraction, and SEM—scanning electron microscopy); mechanically, by applying a compression
test; and, finally, from a corrosion resistance viewpoint. Using the optimal test processing parameters,
a few demonstrative temporary implants of small dimensions were made via the SLM method. Our
conclusion is that mechanical alloying combined with SLM processing has good potential to manage
3D additive manufacturing for personalised temporary biodegradable implants of magnesium alloys.
The compression tests show results closer to those of human bones compared to other potential
metallic alloys. The applied corrosion test shows result comparable with that of the commercial
magnesium alloy ZK60. [--]
