“…This advantage makes it possible to explore wider material range. For example, it has been used for printing epoxy-based composites or reactive composites [11][12][13], as well as mellitic structures with removable supports [14]. Material jetting is well known for its two significant multi-material printing systems: PolyJet (Stratasys) and Multi Jet Printing (3D Systems).…”

In recent years, Additive Manufacturing (AM) has evolved into a "multi-x" era, such as multi-part design, multi-material, multi-process, multi-mode, multi-scale, multi-dimension, and multi-function. These emerging new features of AM present both tremendous opportunities and challenges for developing and regulating new and novel biomedical materials and devices. This paper focuses on two aspects, namely multi-material and multi-dimension AM. In multi-material 3D printing, the layering step is the key. Modifying the layering method yet without changing the solidifying or bonding principles governing the AM process can enable and significantly advance multi-material 3D printing. In multi-dimensional 3D printing, typically 4D printing and 5D printing, the meaning of "D" is suggested to refer to space-time dimension rather than the number of degrees of freedom in physical space. It is proposed in this paper that an alternative dimension (or 5D) for future 3D printing processes can be that of scale. Scale here refers the different levels of resolution that are used simultaneously within a print. In such a scale dimension, continuous printing of cross-scale or varied resolution design features in a single build process without affecting the overall printing speed and time would be highly desirable. This is probably the first paper reflecting on multi-material 3D printing from the perspective of layering and on multi-dimensional 3D printing with regard to its future development.

“…Now, energetic materials used for defence applications like thermites, nanothermites, CL-20 and RDX are just some of the energetic materials that have been successfully 3D-printed. [2][3][4][5] The most common methods used in these studies are extrusion methods some mimicking Fused Deposition Modelling (FDM) many using Direct Ink Jet Writing (DIW) to print energetic materials. 6 A novel method of additive manufacture, Dry Powder Deposition (DPD) has been developed at Cranfield University and has been used to print thermites 7 (Al/Fe2O3, Al/CuO, Al/Ag2O, Zn/CuO, Al/CaSO4) and RDX.In both cases the combustion properties of both types of materials, whether as a pyrotechnic or a propellant were the initial point of interest.…”

Research into additive manufacturing (AM) has been steadily expanding over the past five decades. Where once only polymeric materials could be reliably printed, AM has been adapted to print with a range of materials such as biological, metallic, ceramic and even foodstuffs. The advantages of manufacturing in an additive manner include; a) a layer-by-layer approach allows the creation of architecturally complex structures, b) a reduction in weight, c) lessening of waste and d) the ability to create parts that that are otherwise difficult or too costly to produce. 1,3,5-Trinitro-1,3,5-triazinane (RDX) is regularly used in explosive systems. Its detonation properties when conventionally manufactured are widely researched and broadly understood. However, recent advances in additive manufacturing technologies have led to greater interest in utilising RDX in this manner. There is growing evidence that emerging formulations and printing methods are changing the detonation properties of RDX composites, the critical diameter among them. This study reports on beginning to understand the detonation properties of additively manufactured RDX via a dry powder printing method.
