“…However, post-processing is possible for DIW. For example, it has also been reported that polishing can also be used as a post-processing technique for the glasses that are fabricated using the DIW process to obtain the specific size and a surface microroughness of <1 nm root mean square for the glass devices to meet application requirements [14]. Moreover, to improve the preparation efficiency of the glass microstructure, in addition to shortening the time in the step of photopolymerization, the heat treatment process of reasonable optimization of 40-50 hours is often more significant than the step of polymerization forming.…”

Not satisfied with the current stage of the extensive research on 3D printing technology for polymers and metals, researchers are searching for more innovative 3D printing technologies for glass fabrication in what has become the latest trend of interest. The traditional glass manufacturing process requires complex high-temperature melting and casting processes, which presents a great challenge to the fabrication of arbitrarily complex glass devices. The emergence of 3D printing technology provides a good solution. This paper reviews the recent advances in glass 3D printing, describes the history and development of related technologies, and lists popular applications of 3D printing for glass preparation. This review compares the advantages and disadvantages of various processing methods, summarizes the problems encountered in the process of technology application, and proposes the corresponding solutions to select the most appropriate preparation method in practical applications. The application of additive manufacturing in glass fabrication is in its infancy but has great potential. Based on this view, the methods for glass preparation with 3D printing technology are expected to achieve both high-speed and high-precision fabrication.

The customized processing of polymer materials in the microscale by high‐resolution 3D printing provides an easy access to advanced applications in the fields of optics, microfluidics, tissue engineering, and life science. However, the 3D printing of enclosed structures in the scale of tens of microns such as closed microfluidic channels remains a challenge as channel structures often are clogged by residual cured resin. Dual‐curing systems based on off‐stoichiometric thiol‐ene and thiol‐ene/epoxy chemistry are well‐known for adhesive‐free bonding in the fabrication of cast or injection molded microfluidic devices. Herein, the first high‐resolution stereolithography 3D printing of a dual‐curing thiol‐ene/epoxy system in the microscale for the fabrication of customized microfluidic devices is presented. In the first curing step, by high‐resolution 3D printing open microfluidic structures are produced. Consecutively, the microchannels are sealed by adhesive‐free dry bonding upon thermal initiation, producing well‐controlled structures with channel sizes down to 80 µm. Before bonding, the intermediate material allows for tailored surface modification with biotin, which allows for consecutive immobilization of various biomolecules. A DNA‐bioassay with specific patterning is shown in the sealed chip. The presented work paves the way toward the fabrication of customized microfluidic devices for a large range of specific bioassays.

of numerous components; labor-intensive and costly tasks which often require highly trained personnel and precision alignment equipment.Breaking this cost barrier calls for a cost-effective and scalable manufacturing solution. In contrast to traditional manufacturing processes, additive manufacturing (AM), also referred to as 3D printing, produces complex volumetric structures by the successive addition of building layers. [3] The evolution of AM has seen a rapid growth in satisfying the everincreasing demands in producing geometrically complex parts and assemblies in a wide range of industries, including automobile, [4] aerospace, [5] biomedical, [6] and architecture. [7] This has the potential to transform existing optical manufacturing processes by allowing for design customization directly from digital models without sacrificing manufacturing speed and cost. Its inherent geometric complexity advantages enable a part-count-reduction (PCR) design for producing a single monolithic part to replace existing multicomponent assemblies, reducing lifecycle cost, improving performance, and eliminating further alignment. [8] AM has made great strides over the years to miniaturize optical components. Two-photon direct laser writing with sub-100 nm voxel resolution has demonstrated the fabrication of microlenses and lens assemblies, but at a rather slow "pointby-point" patterning nature. [9] Inkjet printing benefits from the viscosity and surface tension of larger liquid resin droplets to more quickly 3D print optically smooth surfaces on a solid substrate. [10] However, additional molding steps are required for freestanding optical elements. [11] A significant step in tackling this speed/accuracy trade-off was reported by us and other groups by using projection micro-stereolithography (PµSL) and its derivatives. [12] PµSL parallelizes the 3D printing process by curing an entire fabrication layer in a single exposure, being capable of printing millimeter-sized aspherical lenses in 1 h. [12c] Microcontinuous liquid interface production (µCLIP) reported further fabrication speed improvements by eliminating the lengthy resin-recoating step between the printing layers, [13] further reducing fabrication time to minutes. [12a,d] Apart from photopolymer optics, direct ink writing and computed axial lithography have been used to fabricate gradient index and free form optics from silica-based materials, although they require a sintering process utilizing high temperature over 1000 °C. [14] In addition to 3D-printed optical components, filament deposition 3D printers have been used to fabricate the optomechanics This decade has witnessed the tremendous progress in miniaturizing optical imaging systems. Despite the advancements in 3D printing optical lenses at increasingly smaller dimensions, challenges remain in precisely manufacturing the dimensionally compatible optomechanical components and assembling them into a functional imaging system. To tackle this issue, the use of 3D printing to enable digitalized optomechanical...
