Abstract

Abstract : A nonclassical 3D‐printing technique, 3D NSCRIPT, which employs nonlinear blue waves from light emitting diodes (LEDs) is introduced. This technique generates micro‐ and macroscopic dielectric and metallodielectric structures with seamless depths, which would be challenging to fabricate through conventional 3D printing techniques. 3D NSCRIPT exploits divergence‐free, nonlinear self‐trapped beams elicited during epoxide polymerization to inscribe 3D structures; by embedding patterns in and varying the diameter of nonlinear beams, it is possible to control respectively the geometry and dimensions of the resulting structures. By exploiting the interactions of nonlinear beams, it is moreover possible to configure additional structural complexity. Furthermore, by coupling epoxide polymerization with the simultaneous reduction of gold salts, it is possible to generate 3D structures containing a homogeneous dispersion of Au nanoparticles. To demonstrate the versatility of this technique, various 3D components of the da Vinci catapult were fabricated and assembled into a miniature working device. Abstract : Nonlinear LED waves carry embedded patterns over long distances (>Rayleigh range) in photopolymers and inscribe seamless, thick 3D polymer and metallodielectric objects, which are impossible to make through conventional lithography. Structural complexity is configured by exploiting colliding nonlinear waves and self‐trapped dark beams. As proof of concept, a miniature da Vinci catapult is assembled from components made through this process.
