“…Shen et al [ 63 ] used LIFT to transfer micro-stripes of polyimide, with a thickness of 1.2 µm, with laser fluence of 39 mJ·cm −2 and 50 pulses. The deposited strip height (20 to 140 nm) increases with an increment in the laser fluence (34–52 mJ·cm −2 ).…”

Laser-induced forward transfer (LIFT) and two-photon polymerization (TPP) have proven their abilities to produce 3D complex microstructures at an extraordinary level of sophistication. Indeed, LIFT and TPP have supported the vision of providing a whole functional laboratory at a scale that can fit in the palm of a hand. This is only possible due to the developments in manufacturing at micro- and nano-scales. In a short time, LIFT and TPP have gained popularity, from being a microfabrication innovation utilized by laser experts to become a valuable instrument in the hands of researchers and technologists performing in various research and development areas, such as electronics, medicine, and micro-fluidics. In comparison with conventional micro-manufacturing methods, LIFT and TPP can produce exceptional 3D components. To gain benefits from LIFT and TPP, in-detail comprehension of the process and the manufactured parts’ mechanical–chemical characteristics is required. This review article discusses the 3D printing perspectives by LIFT and TPP. In the case of the LIFT technique, the principle, classification of derivative methods, the importance of flyer velocity and shock wave formation, printed materials, and their properties, as well as various applications, have been discussed. For TPP, involved mechanisms, the difference between TPP and single-photon polymerization, proximity effect, printing resolution, printed material properties, and different applications have been analyzed. Besides this, future research directions for the 3D printing community are reviewed and summarized.

“…This technique was first developed to transfer silicon nanostripes on an ITO-coated glass, using the Backward Transfer configuration (LIIBT, Figure 1.12, left). The interference pattern has also been used to melt and forward transfer either metallic dots to a substrate (Nakata et al, 2021), or nanostripes of polyimide from a uniform polyimide layer (Shen et al, 2021). In the Zero-Gap LIFT techniques, the donor and the acceptor substrates are kept in contact -or with gaps so small that it can be considered zero-gap-, so the material is directly transferred without ejection, once it is detached from the donor.…”

En primer lugar, quiero empezar dando las gracias a Miguel Morales, director y tutor de esta tesis doctoral. Has sido durante estos cuatro años y medio un ejemplo de cómo hacer las cosas bien. Durante este proceso has pasado de ser un director de tesis a un compañero. Gracias por tu ayuda y por tu forma de hacernos crecer a los que estamos alrededor.Continúo con mis compañeros de trabajo, tanto en la Escuela de Industriales como en el Centro Láser. Lo bueno de estar a medio camino entre el Campus Sur y la Castellana es que me he encontrado con dos grupos maravillosos.Gracias a vosotros, compañeros de Siderurgia. A Popi y a Benito, porque fuisteis mis profesores y ahora sois mis compañeros. Gracias a ti, Miguel -el otro, Panizo, el Miguel de la Escuela-, porque vas un pasito por delante siempre, y me allanas el camino por el que voy pasando. Bueno, y además incluso empiezas a apreciar el humor de calidad. También -cómo no-a Jesús y a Yolanda, compañeros de cafés, de prácticas, y de mil ideas -metalúrgicas o no-que hacen que el laboratorio y la fundición sean casa.A Vicente y a José Carlos, que completan el núcleo de Siderurgia.

The assembly of functional materials into microstructures, which extends unique features such as enlarged specific surface areas, effective conduction paths, higher material utilization ratios, and ordered alignment compared to continuous films, has gained prominence in various fields. Achieving high performance in electronics requires cooperation among building blocks, fabrication methods, and device design. However, the remaining challenge is obtaining highly regular and large‐scale patterns with controllable assembly methods while maximizing device performances. Manipulating functional materials with liquid assistance is a feasible approach to realizing controllable dewetting, regular molecule packing, and customized performances. This review focuses on the recent advances in preparing and applying liquid‐induced microstructures. The predominant preparation technologies are summarized, including flow‐enabled assembly, nanoimprint lithography, and capillary‐bridge‐mediated assembly. Furthermore, diverse applications of various microstructure‐based electronics, such as flexible and transparent electrodes, organic field‐effect transistors, gas sensors, photodetectors, and solar cells, are demonstrated.
