“…One of the main advantages of LAPμSL over TPL despite the lower resolution is its scalability, meaning that it can produce larger structures has been shown to be able to produce macroscale cellular architectures in the order of tens of centimeters, as opposed to below 10 cm in TPL. Akin to other light‐based 3D printing techniques, although the primary type of material used are polymers (either stiff and elastic), other types of materials such as ceramics could also be printed by a pre‐ceramic polymer resin, Multi‐material PμSL has also been developed which could be used for shape‐morphing architectures, sometimes known as 4D printing …”

In the past decade, mechanical metamaterials have garnered increasing attention owing to its novel design principles which combine the concept of hierarchical architecture with material size effects at micro/nanoscale. This strategy is demonstrated to exhibit superior mechanical performance that allows us to colonize unexplored regions in the material property space, including ultrahigh strength-to-density ratios, extraordinary resilience, and energy absorption capabilities with brittle constituents. In the recent years, metamaterials with unprecedented mechanical behaviors such as negative Poisson's ratio, twisting under uniaxial forces, and negative thermal expansion are also realized. This paves a new pathway for a wide variety of multifunctional applications, for example, in energy storage, biomedical, acoustics, photonics, and thermal management. Herein, the fundamental scientific theories behind this class of novel metamaterials, along with their fabrication techniques and potential engineering applications beyond mechanics are reviewed. Explored examples include the recent progresses for both mechanical and functional applications. Finally, the current challenges and future developments in this emerging field is discussed as well.

“…Despite significant developments in the field, the full potential of PDC stereolithography has not yet been realized. The range of readily photocurable preceramic polymers remains quite confined and has thus far been limited to polysiloxanes, consequently only SiOC ceramics have been additively manufactured in macro scale [2,17,18,[20][21][22]. A recent study examined 3D printing of SiC by blending acrylate based photopolymers with SiC precursors [23].…”

2019. Additive manufacturing of ceramics from preceramic polymers: A versatile stereolithographic approach assisted by thiol-ene click chemistry. Additive Manufacturing,27, AbstractHere we introduce a versatile stereolithographic route to produce three different kinds of Si-containing thermosets that yield high performance ceramics upon thermal treatment. Our approach is based on a fast and inexpensive thiol-ene free radical addition that can be applied for different classes of preceramic polymers with carbon-carbon double bonds. Due to the rapidity and efficiency of the thiol-ene click reactions, this additive manufacturing process can be effectively carried out using conventional light sources on benchtop printers. Through light initiated cross-linking, the liquid preceramic polymers transform into stable infusible thermosets that preserve their shape during the polymer-to-ceramic transformation. Through pyrolysis the thermosets transform into glassy ceramics with uniform shrinkage and high density. The obtained ceramic structures are nearly fully dense, have smooth surfaces, and are free from macroscopic voids and defects. A fabricated SiOC honeycomb was shown to exhibit a significantly higher compressive strength to weight ratio in comparison to other porous ceramics. 2019.

“…Thus, a stretch-dominated cellular structure of the octet-truss superlattice 26,27 was fabricated using the SOPµSL system as shown in Fig. 1c 28,29 , which is capable of fabricating large-volume, high-resolution complex superlattice structures. The ultraviolet (UV)-curable siloxane resin was formulated based on previous work 28 and was added into the resin bath to form the pre-ceramic parts.…”

The 3D hub design was sliced into a sequence of 2D patterns, which were sequentially transmitted to a spatial light modulator and were illuminated with UV light from a lightemitting diode (LED) array.…”

Reconfigurable beam steering components are indispensable to support optical and photonic network systems operating with high adaptability and with various functions. Currently, almost all such components are made of solid parts whose structures are rigid, and hence their functions are difficult to be reconfigured. Also, optical concentration beam steering is still a very challenging problem compared to radio frequency/microwave steering. Here we show a watermill-like beam steering system that can adaptively guide concentrating optical beam to targeted receivers. The system comprises a liquid droplet actuation mechanism based on electrowetting-on-dielectric, a superlattice-structured rotation hub, and an enhanced optical reflecting membrane. The specular reflector can be adaptively tuned within the lateral orientation of 360°, and the steering speed can reach~353.5°s −1 . This work demonstrates the feasibility of driving a macro-size solid structure with liquid microdroplets, opening a new avenue for developing reconfigurable components such as optical switches in next-generation sensor networks.
