Researchers developed a novel method for one-step 3D printing of structural colors using woodpile photonic crystals (WPCs). This technique enables vibrant, arbitrary shapes with enhanced color control without postprocessing, advancing photonic materials.

Area of Science:

Materials Science
Optics
Nanotechnology

Background:

Direct 3D printing of micrometer-scale structural colors remains a significant challenge.
Woodpile photonic crystals (WPCs) offer potential for structural color generation but typically require top illumination and advanced fabrication.

Purpose of the Study:

To develop a one-step 3D printing method for arbitrary shapes with structural colors.
To overcome limitations of existing methods requiring subwavelength features or postprocessing.

Main Methods:

Fabrication of WPCs using two-photon lithography (TPL).
Devised a strategy to support high-order photonic cavity modes for side illumination.
Demonstrated one-step printing of 3D photonic structural colors.

Keywords:

3D structural colors color printing high-order photonic cavity modes two-photon lithography woodpile photonic crystals
