Claim:
1. An apparatus for three-dimensional additive manufacturing comprising: an ultrashort pulse laser, wherein the ultrashort pulse laser generates an electromagnetic radiation, wherein the electromagnetic radiation comprises a wavelength, a pulse repetition rate, a pulse width, a pulse energy, and an average power; a focusing mechanism comprising a focus range, and wherein the focusing mechanism is configured to focus the electromagnetic radiation into a focal region; a powder delivery system, wherein the powder delivery system comprises: a computer coupled to the ultrashort pulse laser, wherein the computer is configured to adjust the pulse repetition rate and the average power of the ultrashort pulse laser and configured to program the electromagnetic radiation into temporally arbitrarily grouped micro and macro pulses and to spatially shape the micro and macro pulses.
