“…In this study we introduced a large area fine resolution sintering optics design to sinter a 2.3 mm by 1.3 mm area of sub-μm thick metal nanoparticle layer with an optical resolution of 1.2 μm in one shot. This design allows for the application of the system in high throughput metal/polymer micro-AM production environments such as fabrication of IC packaging building blocks, fabrication of 3D microcomponents/assemblies for applications in microelectromechanical systems (MEMS), biochips, photonic crystals, microfluidic chips, microsensors, and micro-optoelectromechanical systems (MOEMS) along with other possible applications [38][39][40]…”

This paper presents the optics design for a microscale Selective Laser Sintering (μ-SLS) system that aims to allow large areas of nanoparticles to be sintered simultaneously while still maintaining micrometer scale feature resolutions in order to improve the throughput of the microscale additive manufacturing process. The optics design is shown to be able to sinter a 2.3 mm by 1.3 mm area of metal nanoparticles that have been spread into a ~400 nm thick layer with a feature resolution of ~3 μm in a single shot. The optical resolution of this system is shown to be ~1.2 μm indicating that only about 2-3 pixels are needed to form a good sintered part. In addition, using the optical design presented in this paper, it is estimated that the μ-SLS system should be able to achieve a volumetric throughput of ~63 mm 3 /hr, making this process one of the highest throughput processes available today for the microscale additive manufacturing of three-dimensional metal structures.

“…Unlike micro-laser beam machining and lithographic techniques, it does not require a very expensive setup, which enables the fabrication of miniatures at an economically reasonable cost. 53 Micromilling and micro turning are the two most used mechanical cutting processes. Recently, multicutter-based micromilling process has been studied 54 and found to be more economic and faster when compared to other contemporary micromachining processes.…”

“…LIGA (German abbreviation for Lithography, Galvanoformung (electroplating) and Abformung (Molding)) enables the precise manufacturing of high aspect ratio microchannels ranging from 100–1000 µm. 53 LIGA exploits all the advantages of X-ray lithography. It involves high-energy X-rays and galvanizing techniques to fill the mold by a metal.…”

Microchannels are primarily used in biomedical devices and microfluidic applications. Fabrication of microchannels has always been a tough task using conventional manufacturing technologies. Various types of materials are in use for fabricating microchannels in different types of applications including metals, polymers and ceramics. A number of methods are in use for fabricating different types of microchannels. These processes include both conventional and nonconventional fabrication techniques such as micromilling, lithography, embossing processes and laser ablation processing. During the recent years, some hybrid techniques have also been developed for fabrication of microchannels. This survey of various literatures reveals a broad spectrum of different processes used for fabricating microchannels. Currently, laser micromachining has been evolved as a potential technology for fabricating microchannels. Laser processing has been proved to be the most time efficient and clean. In this article, fabrication processes for creating microchannels have been reviewed with special emphasis on laser micromachining. This article mostly addresses the fabrication techniques for creating surface microchannels.

“…In general, the main challenges to micro manufacturing are cost, accuracy, precision, and standardization. [101] These challenges stem from a number of different technical concerns, for example in industrial forming operations, grain sizes are generally considered small and homogenous but with micro manufacturing grains can be considered anisotropic which adds complexity to forming operations as shown in Fig. 43.…”

Hydroforming is a relatively new metal forming process with many advantages over traditional cold forming processes including the ability to create more complicated components with fewer operations. For certain geometries, hydroforming technology permits the creation of parts that are lighter weight, have stiffer properties, are cheaper to produce and can be manufactured from fewer blanks which produces less material waste. This paper provides a detailed survey of the hydroforming literature of both established and emerging processes in a single taxonomy. Recently reported innovations in hydroforming processes (which are incorporated in the taxonomy) are also detailed and classified in terms of “technology readiness level”. The paper concludes with a discussion on the future of hydroforming including the current state of the art techniques, the research directions, and the process advantages to make predictions about emerging hydroforming technologies.
