Abstract Two‐Photon Lithography, thanks to its very high sub‐diffraction resolution, has become the lithographic technique par excellence in applications requiring small feature sizes and complex 3D pattering. Despite this, fabrication times required for extended structures remain much longer than those of other competing techniques (UV mask lithography, nanoimprinting, etc.). Its low throughput prevents wide adoption industrial applications. To increase it, over years different solutions have been proposed, although their usage is difficult generalize may be limited depending on specific application. A promising strategy further opening a concrete window industry, lies combination with holography approaches: this way it possible generate dozens foci from single laser beam, thus parallelizing periodic structures, or engineer intensity distribution writing plane way, obtaining microstructures exposure. Here, fundamental concepts behind high‐speed Lithography are discussed, literary production recent that exploits such reviewed, contextualized according topic covered.

Additive manufacturing (AM), which is based on the principle of layer-by-layer shaping and stacking discrete materials, has shown significant benefits in fabrication complicated implants for tissue engineering (TE). However, many native tissues exhibit anisotropic heterogenous constructs with diverse components functions. Consequently, replication biomimetic using conventional AM processes a single material challenging. Multimaterial 3D 4D bioprinting (with time as fourth dimension) emerged promising solution constructing multifunctional that can mimic host microenvironment better than single-material alternatives.

Abstract Light‐based 3D printing has received significant attention due to several advantages including high speed and resolution. Along with the development of new technologies, material design is key for next generation light‐based printing. Conventional printable polymeric materials, also known as photopolymers or photoresins, often lead thermosets–polymer networks cross‐linked by permanent covalent bonds which bring limited adaptability restricted reprocessability. Dynamic that can reversibly break reform enable network rearrangement, thereby offering unprecedented properties materials such adaptability, self‐healing, recycling capabilities. Hence, introducing dynamic into a promising strategy further expand meet diverse application scenarios printed multi‐functional moreover more demanding sustainable nature‐inspired considerations (e.g., self‐healing). Herein, an overview recent advances in printing, aiming bridge these two research fields presented. Importantly, current challenges are analyzed perspectives developing their potential applications provided.
