1. A metal composite, comprising:
a core of a mechanical alloy of titanium, zirconium, and niobium obtained by a 3D printing method; and
a shell of an alloy of titanium, zirconium and niobium obtained by a 3D printing method that covers at least a portion of the core,
wherein
the core mechanical alloy comprises from 10-30% atomic percentage of niobium, from 5-20% atomic percentage of zirconium, and from 60-75% atomic percentage of titanium, relative to the total number of atoms of the core,
the core mechanical alloy is in the form of grains having an average particle size of from 1 to 10 μm,
a porosity of the core is from 0.5 vol % to 2.5 vol %,
the shell alloy comprises from 10-30% atomic percentage of niobium, from 5-20% atomic percentage of zirconium, and from 60-75% atomic percentage of titanium, relative to the total number of atoms of the shell,
a porosity of the shell is from 5.0 vol % to 15 vol %,
a crystallinity of the core determined by X-ray diffraction is in the range of 60 vol % to 99.9 vol % relative to the total volume of the core, and
a crystallinity of the shell determined by X-ray diffraction is no more than 1.0 vol % relative to the total volume of the shell.
