“…Therefore, more research is required on providing materials with new features [ 1 , 2 , 3 ] with the minimum environmental cost, as demanded by today’s society. In this way, the use of 3D printing technologies in electronics has great potential since it allows the integration of sensors, conductors, devices with different electronic functions, etc., in the manufacturing process of three-dimensional objects at an affordable cost, while maintaining freedom in design [ 4 , 5 ].…”

There is need for developing novel conductive polymers for Digital Light Processing (DLP) 3D printing. In this work, photorheology, in combination with Jacobs working curves, efficaciously predict the printability of polyaniline (PANI)/acrylate formulations with different contents of PANI and photoinitiator. The adjustment of the layer thickness according to cure depth values (Cd) allows printing of most formulations, except those with the highest gel point times determined by photorheology. In the working conditions, the maximum amount of PANI embedded within the resin was ≃3 wt% with a conductivity of 10−5 S cm−1, three orders of magnitude higher than the pure resin. Higher PANI loadings hinder printing quality without improving electrical conductivity. The optimal photoinitiator concentration was found between 6 and 7 wt%. The mechanical properties of the acrylic matrix are maintained in the composites, confirming the viability of these simple, low-cost, conductive composites for applications in flexible electronic devices.

“…The bodies of 3D‐printed magnetic‐driven robots are composed of either soft or hard magnetic materials. [ 125 ] Typically, NdFeB microparticles, SPIONs, [ 126 ] Ni/Ti bilayer coatings, [ 127 ] and other magnetic materials are embedded in the robots’ bodies or deposited on the body surfaces. Based on different 3D printing technologies and application scenarios, various 3D printing materials are used as the hosting matrix for the magnetic materials, including alginate, [ 126b ] silicone, [ 128 ] SU‐8, [ 127 ] polyethylene‐polypropylene glycol, [ 126c ] hydrogel, [ 20b ] and so on.…”

The research of functional magnetic materials has become a hot topic in the past few years due to their fast, long‐range, and precise response in diverse environments. Functional magnetic devices using different magnetic materials and structure designs have been developed and demonstrated good advantages to enable various applications. However, the required magnetic materials and structure designs for diverse functions also increase the fabrication difficulties while developing such devices. 3D printing technology presents a powerful and promising manufacturing approach to rapidly fabricate functional magnetic devices of complex geometries in multiple materials and scales. Here, various 3D printing strategies and the underlying mechanisms of functional magnetic materials for several primary applications are systematically reviewed, including, magnetic anisotropy for property enhancement, magnetic robots, magnetic components in electronics, and magneto‐thermal devices. Finally, the current challenges and future perspectives in engineering 3D printed functional magnetic devices are discussed.

Vat photopolymerization (VP) is one of the most remarkable additive manufacturing techniques today and has been used for a variety of applications, from materials research to product manufacturing. The main challenge with VP is the limited choice of compatible materials, which motivates significant interest in VP materials development. We provide a brief overview of the materials that are currently accessible via VP and highlight recent advances in the field. We also provide perspective on expanding the library of materials compatible with VP using in situ materials synthesis.
