1. A spark plug, comprising:
a shell;
an insulator that is at least partially disposed within the shell;
a center electrode that is at least partially disposed within the insulator and includes a center electrode base;
one or more center electrode tip(s) that are formed on the center electrode base;
one or more ground electrode(s) that include one or more ground electrode base(s); and
one or more ground electrode tip(s) that are formed on the ground electrode base(s), each center electrode tip opposes one or more ground electrode tip(s) across one or more radial spark gap(s), wherein each of the center electrode tip(s) and each of the ground electrode tip(s) is formed by an additive manufacturing process.
