Abstract:
The present disclosure provides methods, systems, and apparatuses relating to hardware configurations for performing multi-wavelength three dimensional (3D) printing using photoinhibition. In at least one aspect, a system for 3D printing comprises a reservoir capable of holding a liquid including a photoactive resin, a build head that undergoes relative motion within the reservoir during 3D printing of a 3D object on the build head, a light projection device that projects a photoinitiation light beam at a first wavelength into a build area within the liquid, and a plurality of light sources arranged with respect to the light projection device and the reservoir that project a plurality of photoinhibiting light beams into the build area at a second wavelength. Each of the plurality of photoinhibition light beams may be projected at a peak intensity in a different respective position in the build area.
