“…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. Figure 1 shows the microchannels machined using multicutter milling machine.…”

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.

“…Using two separated plates as the reforming unit might slightly reduce the heat-transfer efficiency, however, it was convenient to coat catalyst inside microchannels and change the microchannel plate for experiments. Moreover, the microchannel plate could be machined by micro milling [16] or wire-electrode cutting technology, which could effectively reduce the machining cost and improve the processing efficiency. Four electrical heaters and a thermocouple were equipped inside the cover plates to supply necessary heat and to control the heating temperature.…”

“…The micro-channel reactor is a better alternative as a fuel processor due to the relative ease of scale increase; and the study of the micro-channel reactors has also demonstrated the enhancement of mass and heat transfer in comparison with the traditional reactor for hydrogen production [6,7]. For a micro-channel reactor, the catalyst support is usually a metal sheet such as the stainless steel sheet with straight micro-channels [8], or the porous sintered felts such as copper fiber sintered felts [9e11]. It has been known that the ratio of surface area to volume is large for the micro-channel reactor with multi-micro-channels, but it can be much larger when changing the structure of catalyst support from 'straight channels' to the 'micro-pin-fin arrays' as shown in Fig.…”
