1. An ink composition conferring radiation-absorbing properties mimicking bone tissue, wherein the ink composition comprises dissolved radiation-absorbing molecules, the radiation-absorbing molecules composed of chemical elements, wherein each chemical element has an atomic number Z which is:
an atomic number in the range Z=1−22, wherein the radiation-absorbing molecules comprise a radiation-absorbing salt selected from the group consisting of:
phosphate salts,
and a combination of any two or more phosphate salts
wherein the radiation-absorbing phosphate salt or phosphate salts are water-soluble, non-volatile compounds having a boiling point ≥200° C., and wherein the ink composition has a viscosity in the range between 1-30 millipascal-second (mPa·s).
