“…The isomerization state of azobenzene compounds transforms from trans to cis under illumination at certain wavelengths (mostly in the UV region) [125]. For example, azobenzene compounds were mixed with photopolymer liquid resins for SLA and used to fabricate a photoresponsive smart window ( Figure 10A) [126]. The transmission spectra were measured with crossed polarizers.…”

AbstractThree-dimensional (3D) printing is a new paradigm in customized manufacturing and allows the fabrication of complex optical components and metaphotonic structures that are difficult to realize via traditional methods. Conventional lithography techniques are usually limited to planar patterning, but 3D printing can allow the fabrication and integration of complex shapes or multiple parts along the out-of-plane direction. Additionally, 3D printing can allow printing on curved surfaces. Four-dimensional (4D) printing adds active, responsive functions to 3D-printed structures and provides new avenues for active, reconfigurable optical and microwave structures. This review introduces recent developments in 3D and 4D printing, with emphasis on topics that are interesting for the nanophotonics and metaphotonics communities. In this article, we have first discussed functional materials for 3D and 4D printing. Then, we have presented the various designs and applications of 3D and 4D printing in the optical, terahertz, and microwave domains. 3D printing can be ideal for customized, nonconventional optical components and complex metaphotonic structures. Furthermore, with various printable smart materials, 4D printing might provide a unique platform for active and reconfigurable structures. Therefore, 3D and 4D printing can introduce unprecedented opportunities in optics and metaphotonics and may have applications in freeform optics, integrated optical and optoelectronic devices, displays, optical sensors, antennas, active and tunable photonic devices, and biomedicine. Abundant new opportunities exist for exploration.

“…The intensity of the transmitted light for 3D‐printed samples can be increased up to 80% from their initial values of 40–50% in the visible and NIR spectral range by post‐processing of the samples. [ 93 ] The deposition of a thin resin film on the printed samples decreases the surface roughness, and the associated scattering/diffraction of the incident light. This post‐printing surface modification increases the transmittance of these samples to accepted levels ( Figure A).…”

Prospects for Additive Manufacturing in Contact Lens Devices

Additive manufacturing (3D printing) has the ability to architect structures at microscale, giving rise to the development of functional contact lenses (CLs) with inbuilt sensing capabilities. 3D printing technology enables fabrication of CLs without surface geometry restrictions. Spherical, nonspherical, symmetric, and asymmetric lenses can be manufactured in an integrated production process. Advantages of 3D printing over conventional techniques include fast and easy production, one‐step manufacturing, and no post processing such as grinding or polishing. In addition, and most significantly, 3D printing can create chambers within the wall of the lenses by taking the advantage of computer‐aided modeling and layer‐by‐layer deposition of the materials. These inbuilt chambers can be used for loading drugs and sensing elements. The computer‐aided design modeling can allow for manufacturing of patient‐specific CLs. This article focuses on the 3D‐printing approaches and the challenges faced in fabricating CLs. 3D‐printing technology as a technique for manufacturing of CLs is discussed, in addition to the manufacturing challenges and the possible solutions to overcome the obstacles.

Additive manufacturing processes are capable of fabricating optical devices, including the production of contact lenses, waveguides, and Fresnel lenses used in a variety of applications. This study presents a novel fabrication method for high‐quality Fresnel lenses through a vat photopolymerization 3D printing method. Here, the 3D printing process is integrated with the micro/nanostructure fabrication to produce 3D optical components with imprinted micro/nanostructures in a single step. This straightforward approach allows imprinting a micro‐pattern (5 μm features size) onto the flat surface of a 3D‐printed Fresnel lens, achieve light focusing properties along with holographic rainbow effects. The printed lenses achieve focal lengths within ≤8 mm deviation from the predicted values. Such holographic Fresnel lenses are highly desirable in imaging‐based miniature spectrometers for mechanoluminescence sensoring. Thus, the masked stereolithography (MSLA) based 3D printing process can produce normal and holographic Fresnel lenses, vital in optical sensing and communication.
