“…The mold filling depends on the mold temperature and the filling pressure [ 3 ] and is also limited by the surface tension of the cast-material. Some complex three dimensional shapes were realized by casting of metal with a low melting temperature [ 3 – 4 ]. Dimensions of cast details are in the submillimeter- and microscale, and due to the mentioned limitations, applications in the submicron- and nanoscale do not seem to be feasible.…”

Summary Background: This paper describes the shaping of freestanding objects out of metallic structures in the nano- and submicron size. The technique used, called nanoforging, is very similar to the macroscopic forging process. Results: With spring actuated tools produced by focused ion beam milling, controlled forging is demonstrated. With only three steps, a conical bar stock is transformed to a flat- and semicircular bent bar stock. Conclusion: Compared with other forming techniques in the reduced scale, nanoforging represents a beneficial approach in forming freestanding metallic structures, due to its simplicity, and supplements other forming techniques.

“…The technology has been successfully implemented to produce miniature parts in surgical instruments, dental devices, biotechnology instruments, and mechanical devices [163]. Microcasting is usually identified as an investment casting process, such as lost-wax and lost-mold techniques [164]. The advantages it offers include near net shape, complex parts, low materials loss, and quick production [165].…”

“…Other methods of microcasting include permanent mold and composite microcasting. In permanent mold casting, the research is focused on finding suitable metal or graphite molds for casting miniature parts; while in composite casting, the focus is on connecting or assembling two different materials or structures [164].…”

“…Al, magnesium (Mg), zinc (Zn), tin (Sn), and lead (Pb) [175,176]. Baumeister et al [164] carried out permanent mold microcasting of Al-bronze using both metal (steel) and ceramic (graphite) molds and fabricated microgears of a few millimeters, as shown in figure 8. The method presented is still in the primary stage, due to its millimeter range; however, it can be implemented in practical production line conditions.…”

Composite materials exhibit advantages from the combination of multiple properties, which cannot be achieved by a monolithic material. At present, the use of composite materials in miniaturized scale is receiving much attention in the fields of medicine, electronics, aerospace, and microtooling. A common method for producing miniaturized composite parts is micromanufacturing. There has been, however, no comprehensive literature published that reviews, compares, and discusses the ongoing micromanufacturing methods for producing miniaturized composite components. This study identifies the major micromanufacturing methods used with composite materials, categorizes their subclasses, and highlights the latest developments, new trends, and effects of key factors on the productivity, quality, and cost of manufacturing composite materials. A comparative study is presented that shows the potential and versatility associated with producing composite materials along with possible future applications. This review will be helpful in promoting micromanufacturing technology for fabricating miniaturized products made of composite materials to meet the growing industrial demand.

“…However, limitations include applicable materials, size, shapes, capacity to manufacture high aspect ratio (AR) microparts and microstructuring inner areas. 85 Nowadays, microcasting techniques, namely, permanent mold and investment casting [85][86][87][88][89][90] are being used to manufacture microparts in large quantities. Attempts have been made 91 for mathematical modeling of microcasting processes from microscopic point of view.…”

This article discusses an overview of microforming, microcasting and microwelding processes. In the case of microforming, the processes reviewed are micro deep drawing, microforging, microextrusion, microrolling, microstamping, microhydroforming and incremental microforming. This section also throws some light on how the lasers have been used for microbending and micropunching purposes. The work done in the area of physics of microforming processes has also been discussed briefly. This article also deals with different types of microcasting processes particularly permanent mold and investment microcasting processes. The applications of these microcasting processes have been specified in different fields of engineering, biomedical and so on. Some areas in which further research work is needed have been identified. It includes both theoretical and experimental works which need attention. The last part of this article deals with microjoining in general and laser microjoining in particular. This section discusses the types of the lasers that are being used for microjoining purposes. The process parameters (laser, optics, system and material) have been explained, and some work done on the parametric analysis has been reported briefly. Various applications of laser microjoining have been elaborated before the last section on concluding remarks. This last section presents, in very brief, the areas in which further work is required in microjoining processes.
