“…[35,36] Furthermore, AM can allow direct access to complex structures, providing control over material properties and behaviors through the design of 3D architecture. [37,38] This advantage is exemplified by the emerging applications of AM for developing materials with high configuration complexity in the fields of thermal management, [39,40] biomedical engineering, [41] and acoustics. [42,43] Previous research efforts for AM of large-size carbon products have primarily focused on printing carbon additive slurries (e.g., through direct ink writing [DIW]) or polymeric carbon precursors (most through UV-assisted printing).…”

focused on research and product development of carbon-based materials, exemplified by the discoveries of fullerene, [10] carbon nanotubes [11] and graphene, [12] as well as fabrication of porous carbon [13] and carbon black additives for many commercial applications. [14] However, most industries can only employ these functional carbon materials as fillers, necessitating additional components, often polymer matrices, for imparting processability. [15,16] The presence of matrix materials can greatly diminish many intrinsic advantages of carbons, leading to compromised material performance. Furthermore, necessary steps of mixing and processing in composite manufacturing may lead to high energy consumption and carbon footprint, resulting in an enormous negative impact on the environment. Enabling ondemand manufacturing of carbons with controlled macroscopic structures is necessary to unlock their full potential in various applications, while addressing urgent societal challenges including climate change and environmental sustainability.Generally, creating structured carbon materials rely on the use of polymer precursors, combined with pyrolysis-based approaches to allow their conversion to carbon materials. [17][18][19] A common example in this area is carbon fiber manufacturing, which uses polyacrylonitrile (PAN) as a carbon precursor and involves multiple processing steps, including fiber spinning, drawing, thermal stabilization/crosslinking and carbonization. [20] Alternatively, many other carbon precursors have been reported, including pitch-based chemicals, [21] lignin, [22,23] cellulose, [24,25] polyethylene (PE), [26][27][28] polypropylene (PP) [29,30] and polybenzoxazines. [31,32] While these chemical can be effectively converted to carbons, the scope of most work in the area of structured carbon production is associated with fibril materials; [33] the ability of manufacturing carbon with complex architectures at macroscopic scale is largely underexplored.In recent years, additive manufacturing (AM) has attracted significant attention in both academic research labs and largescale manufacturing facilities, leading to wide recognition as a key future manufacturing technology. [34] AM can create products through layer-by-layer addition without the need for tools and molds, which is also inherently less wasteful than traditional subtractive-based methods due to its significantly Carbon materials are essential to the development of modern society with indispensable use in various applications, such as energy storage and high-performance composites. Despite great progress, on-demand carbon manufacturing with control over 3D macroscopic configuration is still an intractable challenge, hindering their direct use in many areas requiring structured materials and products. This work introduces a simple and scalable method to generate complex, large-scale carbon structures using easily accessible materials and technologies. 3D-printed, commercial polypropylene (PP) parts can be thermally stabilized through cracking-faci...

Ceramic additive manufacturing allows the fabrication of small series of complex parts without the high costs of molds usually associated with traditional ceramic processing. Although research into ceramic 3D printing by all technologies started back in the 90s, its industrial application is still quite restricted when compared to polymers and metals, which is related to the limited availability and costs of equipment and materials for such applications. This review examined the advantages and limitations of each process (binder jetting, direct ink writing, directed energy deposition, fused deposition, material jetting, selective laser sintering, selective laser melting, and vat photopolymerization), discussing their particularities. It also summarized the commercially available 3D printers and raw materials for ceramic processing, pointing out to trends and challenges of each technology.

In this study, h-BN was added to the cordierite composition obtained from zeolite, which was prepared by the determined stoichiometry to facilitate machinability and increase thermal conductivity. Sintering behavior, hardness, machinability, and thermal/electrical properties of the samples obtained by sintering the compounds at different times were investigated. Thanks to these features, it is aimed to use cordierite as an alternative material to integrated circuit substrates and electronic packaging materials. The produced samples were analyzed by X-ray diffraction analysis, examined by scanning electron microscopy, and field emission scanning electron microscopy. Afterward, thermal properties such as thermal diffusivity, thermal conductivity, and electrical properties such as electrical conductivity and dielectric permittivity were measured. The hardness and machinability of samples were investigated. Cordierite, spinel, glassy phase, and h-BN phase were detected, and it was observed that the blocky cordierite grains turned into equiaxed grains with the increase of the h-BN. According to the results obtained from the thermal conductivity test, it was seen that the h-BN additive increased the thermal conductivity value in general. In addition, it was determined that with the increase of h-BN, the hardness decreased, and the machinability properties of the samples improved.
