Abstract
Methods, devices and systems that allow three-dimensional printing of material with high resolution are described. One example system includes a two-photon polymerization (TPP) subsystem including a first light source coupled to an optical fiber positioned to deliver a first laser light to a scanning optical device, and an optical projection subsystem comprising a second light source configured to provide a second light to a digital projection device. A dichroic mirror is positioned to receive light corresponding to the first and the second light source, and an objective lens positioned to provide illumination to a target material for 3D printing. The dichroic mirror is configured to allow light from one of the light sources to pass therethrough to the objective lens, and to allow light corresponding to the other light source to be reflected towards the objective lens to enable simultaneous illumination of the target material.
