“…The AM of microstructures, similarly to the macroscale field, allows the fabrication of complicated shapes that are impossible to obtain with other processes. The AM methods also permit to use a large variety of materials and materials combinations [159][160][161][162][163]. Some of the processes described have been developed by starting from the macroscale to increase their performances and resolutions, making them suitable for building microstructures and MEMS.…”

Recently, additive manufacturing (AM) processes applied to the micrometer range are subjected to intense development motivated by the influence of the consolidated methods for the macroscale and by the attraction for digital design and freeform fabrication. The integration of AM with the other steps of conventional micro-electro-mechanical systems (MEMS) fabrication processes is still in progress and, furthermore, the development of dedicated design methods for this field is under development. The large variety of AM processes and materials is leading to an abundance of documentation about process attempts, setup details, and case studies. However, the fast and multi-technological development of AM methods for microstructures will require organized analysis of the specific and comparative advantages, constraints, and limitations of the processes. The goal of this paper is to provide an up-to-date overall view on the AM processes at the microscale and also to organize and disambiguate the related performances, capabilities, and resolutions.

“…73 Another advantage of 3D printing is the ability to produce complex features 74 and intricate structures 75 based on accurate CAD design with minimal post-process machining and finishing. 76 Besides, 3D printing is cost-effective and offers high versatility 77 such as custom-made components. 78 As an example, 3D printing can fabricate a custom dual shoot square funnel used in an ADM. 51 Polylactic acid (PLA) is used as the raw material in 3D printing.…”

An automatic system in equipment can be recognized as a systematic control system to minimize human tasks or automatically complete repetitive tasks without human involvement. This review paper focused on the dispensing machines in the medical field particularly the design development of the automated dispensing machines which can be considered as one of the important technologies in pharmacy. This paper also briefly describes the main criteria for fabricating the dispensing machine. Next, different fabrication methods of the dispensing machine such as simple fabrication and 3D printing as well as the materials used in 3D printing are also thoroughly discussed. The last section consisted of the evaluation methods to justify the developed devices by comparing the performance of fabricated products and also through surveys and feedback from patients and medical staff. Based on the performance evaluation of automated dispensing machines as reported in the literature, it can be concluded that the implementation of an automated dispensing machine is necessary for the high-quality guarantee of community healthcare.

“…Among additive fabrication approaches, including fused filament fabrication, selective laser sintering, and material jetting, the light-based technique is most suitable for micro-architected metamaterials due to its high resolution (<100 µm) and robust mechanical properties of photopolymers [28][29][30]. However, only a small fraction of 3D features and architectures can be realized, as most current AM techniques are still limited to self-supporting architectures with a small number of unit cells.…”
