“…The multimaterial (MM) 3D printing capability can greatly enrich the performance and functionality of printed 3D objects and even realize the performance and functionality which do not exist in the structures printed with one single material. As presented in figure 1, up to now, the MM 3D printing capability has been implemented to various mainstream 3D printing technologies such as fused deposition modeling (FDM) [2][3][4][5][6][7][8], direct ink writing (DIW) [9][10][11][12][13][14][15][16][17][18][19], inkjet [20][21][22][23][24][25][26][27][28][29], as well as digital light processing (DLP) [30][31][32][33][34].…”

Multimaterial (MM) 3D printing shows great potential for application in metamaterials, flexible electronics, biomedical devices and robots, since it can seamlessly integrate distinctive materials into one printed structure. Among numerous MM 3D printing technologies, digital light processing (DLP) MM 3D printing is compatible with a wide range of materials from hydrogels to ceramics, and can print MM 3D structures with high resolution, high complexity and fast speed. This paper introduces the fundamental mechanisms of DLP 3D printing, and reviews the recent advances of DLP MM 3D printing technologies with emphasis on material switching methods and material contamination issues. It also summarizes a number of typical examples of DLP MM 3D printing systems developed in the past decade, and introduces their system structures, working principles, material switching methods, residual resin removal methods, printing steps, as well as the representative structures and applications. Finally, we provide perspectives on the directions of the further development of DLP MM 3D printing technology.

Additive manufacturing (AM), which is based on the principle of layer‐by‐layer shaping and stacking of discrete materials, has shown significant benefits in the fabrication of complicated implants for tissue engineering (TE). However, many native tissues exhibit anisotropic heterogeneous constructs with diverse components and functions. Consequently, the replication of complicated biomimetic constructs using conventional AM processes based on a single material is challenging. Multi‐material 3D and 4D bioprinting (with time as the fourth dimension) has emerged as a promising solution for constructing multifunctional implants with heterogeneous constructs that can mimic the host microenvironment better than single‐material alternatives. Notably, 4D‐printed multi‐material implants with biomimetic heterogeneous architectures can provide a time‐dependent programmable dynamic microenvironment that can promote cell activity and tissue regeneration in response to external stimuli. This paper first presents the typical design strategies of biomimetic heterogeneous constructs in TE applications. Subsequently, the latest processes in the multi‐material 3D and 4D bioprinting of heterogeneous tissue constructs are discussed, along with their advantages and challenges. In particular, the potential of multi‐material 4D bioprinting of smart multifunctional tissue constructs is highlighted. Furthermore, this review provides insights into how multi‐material 3D and 4D bioprinting can facilitate the realization of next‐generation TE applications.This article is protected by copyright.

Abstract3D printing is now recognized as a significant tool for medical research and clinical practice, leading to the emergence of medical 3D printing technology. It is essential to improve the properties of 3D‐printed products to meet the demand for medical use. The core of generating qualified 3D printing products is to develop advanced materials and processes. Taking advantage of nanomaterials with tunable and distinct physical, chemical, and biological properties, integrating nanotechnology into 3D printing creates new opportunities for advancing medical 3D printing field. Recently, some attempts are made to improve medical 3D printing through nanotechnology, providing new insights into developing advanced medical 3D printing technology. With high‐resolution 3D printing technology, nano‐structures can be directly fabricated for medical applications. Incorporating nanomaterials into the 3D printing material system can improve the properties of the 3D‐printed medical products. At the same time, nanomaterials can be used to expand novel medical 3D printing technologies. This review introduced the strategies and progresses of improving medical 3D printing through nanotechnology and discussed challenges in clinical translation.
