Methods of forming components for earth-boring tools and related components and earth boring tools

A method of forming a superabrasive component for an earth-boring tool, the method comprising:

• disposing a first level of a first volume of unbonded particulate superabrasive material on a surface of a base structure;
• depositing a first carbon-containing precursor material onto the first level;
• directing an energy beam onto the first carbon-containing precursor material to form a first level of a first volume of bonded polycrystalline superabrasive material having carbon-carbon atomic bonds between adjacent particles;
• repeating the disposing, depositing and directing to form the first level of the first volume of bonded polycrystalline superabrasive material to complete the first volume of bonded polycrystalline superabrasive material;
• disposing a first level of at least a second volume of unbonded particulate superabrasive material on the first volume of bonded polycrystalline superabrasive material;
• depositing a second carbon-containing precursor material onto the first level of the at least a second volume of particulate superabrasive material;
• and
• directing an energy beam onto the second carbon-containing precursor material to form a first level of at least a second volume of bonded polycrystalline superabrasive material having carbon-carbon atomic bonds between adjacent particles and to bond with carbon-carbon atomic bonds particles of the first level of the second volume of bonded polycrystalline superabrasive material to an uppermost level of the first volume of bonded polycrystalline superabrasive material;
• and
• repeating the disposing, depositing and directing to form the first level of the second volume of bonded polycrystalline superabrasive material to complete the at least a second volume of bonded superabrasive material.
