“…He quantified the optimal powder parameters such as the particle size (20-35 mm), compaction rate r Tapped /r Bulk (1.3-1.4), flowability ff c , defined as the ratio of consolidation stress s 1 and the compression strength s c (5-7), and powder bed surface roughness (10-25 mm). The need for at least one post-processing step (cold-isostatic pressing, [61] infiltration with preceramic polymers [62,63] or liquid metals, [51,64] chemical vapor infiltration, [65] and sintering [66,67] ) reduces the productivity of three-dimensional printing methods, so several approaches exist to increase the green density. It was observed that implementation of binder-coated particles effectively improves the green and sintered strengths.…”

This paper offers a review of present achievements in the field of processing of ceramic-based materials with complex geometry using the main additive manufacturing (AM) technologies. In AM, the geometrical design of a desired ceramic-based component is combined with the materials design. In this way, the fabrication times and the product costs of ceramic-based parts with required properties can be substantially reduced. However, dimensional accuracy and surface finish still remain crucial features in today's AM due to the layer-by-layer formation of the parts. In spite of the fact that significant progress has been made in the development of feedstock materials, the most difficult limitations for AM technologies are the restrictions set by material selection for each AM method and aspects considering the inner architectural design of the manufactured parts. Hence, any future progress in the field of AM should be based on the improvement of the existing technologies or, alternatively, the development of new approaches with an emphasis on parts allowing the near-net formation of ceramic structures, while optimizing the design of new materials and of the part architecture.

“…SiSiC lattice truss structures with variable ligament lengths (see Figure 2f) with Si volume ranging from 8 to 82% were fabricated by Ref. [63] It was shown that the decreasing fracture of coarser Si particles in the starting powder positively influenced the porosity of the printed objects.…”

“…Although the porosity is not always a desired feature on bulk ceramics, it may be beneficial for the creation of infiltrated CMCs. In fact, most of the research groups have used additive manufacturing to assemble a ceramic backbone for subsequent metal infiltration, to create a multiphase composite [6][7][8][9][10][11][12][13][14][15][16][17]. However, no previous studies on AM for producing multiphase composites have reported the use of the aforementioned RMP infiltration technique.…”

“…Song et al [10] made a high temperature C/SiC composite sandwich structure with stitched lattice truss core. Fu et al [11] fabricated silicon/silicon carbide ceramic lattice composites by the threedimensional printing (3DPTM) from Si/SiC/dextrin powder blends. The porous preforms exhibit excellent infiltration behavior for liquid Si at 1500 C in vacuum.…”
