“…Indeed, major progress in vat polymerization [ 1 , 2 ], selective laser melting [ 3 , 4 ], and direct ink writing (DIW) [ 5 , 6 , 7 ] has demonstrated the variety of means in which advanced composites can be used to construct geometries and structures that traditional manufacturing techniques have difficulty fabricating. DIW 3D printing, a technology under the ISO/ASTM 52900:2015 category of material extrusion, includes ink jet printing [ 8 , 9 , 10 ], micropen writing [ 11 , 12 ], fused filament fabrication (FFF) [ 13 , 14 , 15 ], hot-melt extrusion [ 16 , 17 ], and robocasting [ 18 , 19 ] and is especially useful because of the wide array of material selection available and the continued development which increases the capabilities of these techniques. DIW, in particular, is especially suitable for advanced materials capabilities due to its range of ink formulations and versatility in part extrusion and curing.…”

Additive manufacturing, with its rapid advances in materials science, allows for researchers and companies to have the ability to create novel formulations and final parts that would have been difficult or near impossible to fabricate with traditional manufacturing methods. One such 3D printing technology, direct ink writing, is especially advantageous in fields requiring customizable parts with high amounts of functional fillers. Nuclear technology is a prime example of a field that necessitates new material design with regard to unique parts that also provide radiation shielding. Indeed, much effort has been focused on developing new rigid radiation shielding components, but DIW remains a less explored technology with a lot of potential for nuclear applications. In this study, DIW formulations that can behave as radiation shields were developed and were printed with varying amounts of porosity to tune the thermomechanical performance.

“…According to the standards set by the Subcommittee of materials and Testing Association of America (ASTM), additive manufacturing technology is divided into seven categories [ 21 , 22 ]. Among them, material spray forming technology [ 23 ], material extrusion technology [ 24 ], and photopolymerization curing technology [ 25 ] have been applied in the forming and manufacturing of energetic materials [ 23 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 ]. Material spray forming technology requires a material to have a lower viscosity so that it can be sprayed from small nozzles; however, photopolymerization curing technology requires more photosensitive resin in the molding material, and the solid content of both should not be high.…”

Direct writing is a rapidly developing manufacturing technology that is convenient, adaptable and automated. It has been used in energetic composites to manufacture complex structures, improve product safety, and reduce waste. This work is aimed at probing the formability properties and combustion performances of aluminum/ammonium perchlorate with a high solid content for direct writing fabrication. Four kinds of samples with different solid content were successfully printed by adjusting printing parameters and inks formulas with excellent rheological behavior and combustion properties. A high solid content of 91% was manufactured and facile processed into complex structures. Micromorphology, rheology, density, burning rate, heat of combustion and combustion performance were evaluated to characterized four kinds of samples. As the solid content increases, the density, burning rate and heat of combustion are greatly enhanced. Based on 3D direct writing technology, complex energetic 3D structures with 91% solid content are shaped easier and more flexibly than in traditional manufacturing process, which provides a novel way for the manufacture of complicated structures of energetic components.
