  • stereo lithography a computer-controlled cold laser is used to cure photocurable epoxy held in a vat, one thin sectional layer at a time.
  • An exemplary composite article manufactured in accordance with the method of the present invention is generally comprised of a freeform- fabricated core to which multiple facing skins are bonded.

Furthermore, and more importantly, the 3D-CAD file specifies channels, receivers, openings, or other integral structural elements that are formed in the core to provide enhanced bonding between the facing skins and the freeform- fabricated core.
