One-step rapid manufacturing of metal and composite parts

A fabrication system for fabricating parts, comprising:

• means for splitting a laser beam into at least two angled beams each of which is not perpendicular to a substrate at a spot location;
• a perpendicular delivery means for feeding metal powder at an angle of approximately 90 degrees to the substrate, wherein the metal powder is delivered in between the two angled beams;
• means for recombining the two angled beams at the spot location on the substrate, means
• means for forming a deposition layer by the laser beam and the metal powder;
• and
• means for fabricating a part from the deposition layers on the substrate.

A system for fabricating parts comprising:

• means for splitting laser beam into a first beam and a second beam;
• means for focusing the first beam and the second beam at a spot location;
• means for feeding material into the spot location coaxially to the laser beam;
• and
• means for forming a deposition layer by melting the material with the laser beam on a support surface.
