Research Progress in 3D Printing Technology for Optoelectronic Devices

Abstract

In recent years, photoelectric devices have seen increasingly profound applications in critical fields such as display technologies, energy systems, and advanced manufacturing. Their technological advancement and performance optimization have become central driving forces in promoting the upgrading of related industries. Leveraging its prominent characteristics, such as high design flexibility, rapid prototyping capabilities, and customizable fabrication of complex structures, 3D printing technology demonstrates unique technical advantages in the field of optoelectronic device manufacturing. This paper systematically reviews the application progress of 3D printing technology in the field of photoelectric devices, including display devices, solar cells, and photodetectors. In addition, the specific application practice and technical breakthrough in the display core devices, such as light-emitting diodes (LEDs) and organic light-emitting diodes (OLEDs), are mainly described. In the future, 3D printing technology will play an important role in the field of optoelectronic devices. Specifically for core display components, it enables more efficient and cost-effective production, thereby driving advancements in display technology toward higher resolution and miniaturization. 3D printing will also bring breakthroughs in improving the efficiency of solar cells and the integration of photodetectors.
