“…The available polymers for MJF are polyamide (PA 11, PA 12) and thermoplastic polyurethane (TPU). MJF is suitable for printing functional mechanical parts or devices, biomedical lattices structures, medical orthotics and prosthetics, mechanical tools, and fluid-tight devices [36,39,[43][44][45][46][47][48].…”

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.

“…This emerging 3D-printing modality is suitable for low volume production of parts with exceptional mechanical strength, high reusability rate of the powder material, faster production speed as an alternative to injection molding [ 23 , 67 , 103 , 104 ]. MJF is capable of printing functional mechanical parts/devices, biomedical lattices structures, medical orthotics and prosthetics, mechanical tools and fluid-tight devices [ 34 , 67 , 103 , 106 , 108 , 109 , 110 , 111 ]. Figure 4 b shows exemplary high-performance lattice structures 3D-printed by MJF 4200 with cell units ranging from 1.134 to 2.246 mm [ 106 ].…”

“…The powder-based process is one of the most significant and popular class of 3D-printing techniques [ 23 , 24 , 25 , 26 , 27 , 28 ]. This popularity is due to the high reusability rate of the powder material, faster production speed, strong functional parts, lower cost, no or minimum support structures, different fields of application and a large range of compatible materials [ 2 , 3 , 12 , 23 , 24 , 25 , 26 , 27 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 ]. The burgeoning field of 3D printing has changed the way products are manufactured in many industries by offering a higher degree of freedom in design and fabrication with a wide range of materials [ 41 , 42 , 43 , 44 , 45 ].…”

Customized manufacturing of a miniaturized device with micro and mesoscale features is a key requirement of mechanical, electrical, electronic and medical devices. Powder-based 3D-printing processes offer a strong candidate for micromanufacturing due to the wide range of materials, fast production and high accuracy. This study presents a comprehensive review of the powder-based three-dimensional (3D)-printing processes and how these processes impact the creation of devices with micro and mesoscale features. This review also focuses on applications of devices with micro and mesoscale size features that are created by powder-based 3D-printing technology.

“…Researchers have already proven that lattice structures are light in weight, have high impact strength, and have high energy absorption capability [6,7]. The mechanical outcome of various cellular arrangements like an octet, tetrahedral, pyramidal, square, and Kagome were investigated by different researchers during the early progress in research of micro-lattices [8][9][10][11][12][13][14][15][16][17][18]. Recent studies revealed that these different orientation lattice structures have better mechanical properties than honeycombs and other available structures [19].…”

Modern-era researchers are interested in searching for new durable and sustainable materials. Cellular structures are the novel solution which exhibits high strength. Micro lattice structures are systematically arranged structures with a high strength-to-weight ratio. Micro Lattice structures can be utilized widely as thermal insulators, energy, and vibration absorber in aircraft and automobile sectors. This study compares the mechanical characteristics of various BCC topologies that are frequently used today. Seven different types of cellular structures with different topologies viz. BCC, BCC enhanced, and BCCz , along with varied unit cell sizes and variations in strut diameter, were fabricated using SLS method. The primary cube was prepared as BCC (Body-Cubic Centered), BCC enhanced, BCCz type with 2×2×2 mm sizes. The SS316 metal was used for these initial cells because to its superior corrosion resistance and improved mechanical performance. These primary cells were repeatedly constructed with patterns in the three X, Y, and Z axes, resulting in total sample sizes of 20 × 20× 20 mm.FE analysis was performed using an FEA solver, and results were compared with experimental results. The result shows that BCCz exhibits superior mechanical properties, whereas BCC enhanced has more strength than regular BCC topology. The BCCZ showed a 62% rise in stresscarrying capacity compared to traditional lattice structure, whereas BCC enhanced showed the 22% rise in stresscarrying capacity. The consequence of size of unit cell is inspected for the outcome of lattices. The smaller unit cell lattice shows more significant yield stress for traditional BCC and enhanced BCC structure. Such a study can undoubtedly open doors for further research on the change in various topologies on the mechanical attributes of lattices under different loading conditions.
