3D printing technology sparks a paradigm shift in one‐step production, mass customization, and waste minimization. Of late, tremendous advances have been made in 3D printing research, including electronic components, energy‐storage gadgets, and medical therapeutic widgets. Lasers with enormous applicable values, ranging from information communication, to health treatment, to industrial manufacturing, have pervasively penetrated and significantly contributed to modern society. However, until now, the platform of 3D printed lasers is absent in all published work. Here, 3D printing technique endowed with great versatility and accessibility allows the possibility to export any desired laser item free from geometrical restraints, constitutional constraints, and skill limitations. Furthermore, based on the biodissolvability, biodegradability, and biocompatibility of the filament, customized 3D printed random laser devices for speckle‐free bioimaging and large‐scale phototherapy are constructed to investigate inherent multistructures and multifunctional biological systems, providing an excellent solution for intriguing yet challenging issues from extremely complicated groups. It is envisioned that 3D printed random lasers will pave the way for a series of long‐anticipated proofs of concept, such as full‐field imaging implants, microfluidic laser sensors, and photonic circuit systems.
