“…On the contrary, for the sandwich multi-materials 3D-H A+VMT+K2CO3, the incorporation of K2CO3 leads to drastic improvement of THR and HRR (Figure 4), as it was expected from the behavior of 3D-K2CO3 sat-liquid [13]). It was the reason of the elaboration of this material.…”

“…Based on a previous paper [13], a sandwich design was conceived. It consists of two skins made of 100% filled layers of EVA-ATH, and a partially-filled core (30% of polymer), as illustrated in Figure 1.…”

“…Nevertheless, a gel containing alginate, VMT and K2CO3 (hereafter called A+VMT+K2CO3) was prepared with a modified gelation process. Based on a previous paper [13], 0.2 g/10 ml of K2CO3 was added in a solution containing 3 wt.-% of alginate and 7 wt.-% VMT (preparation previously described). The solution was then cooled down in a refrigerator for 48 h [30].…”

“…The final material was tested by mass loss cone calorimetry and was found to extinguish immediately after ignition thanks to the release of CO2, H2O, K and KOH quenching the flame, resulting in very low heat release rate. The issue was that the amount of liquid added that was not easily controlled because of the porosity of the system causing unavoidable leaks [13].…”

“…It is believed to act as a char promoting agent and as physical barrier against heat and mass transfer [22]. In a second step, the possibility of including K2CO3 in the hydrogel formulation was examined to take advantage of its action against fire [13]. All samples were tested by mass loss cone calorimetry at an external heat flux of 50 kW/m².…”

Due to their unique properties, hydrogels can be used in many areas of life and science. The main purpose of this work was to present the possibility of using hydrogels as a kind of fire retardant material itself and as a medium in fire retardant materials used, among others, as the extinguishing agents for fires and the suppression agents for the self-ignition of coal in mines (where their low viscosity and high ability to penetration of the protected material is used), protective layers in fabrics and the so-called robot skin (most often applied in the layer-by-layer system), filling in the fire retardant window panels (mostly hybrid hydrogels or hydrogel copolymers are used) and protective emulsions of the wooden elements used in construction and furniture joinery (mainly in combination with silicate and phosphate derivatives). In the presented applications, hydrogels can be used alone, e.g. due to the large water capacity and at the same time the possibility of dilution, or in combination with fire retardants, what very often allows for the multiplication of the extinguishing or fire retardant effect. Due to the multitude of available studies and the speed of scientific development, this review is focused mainly on publications written after 2015.

Abstract3D printing or additive manufacturing (AM) is considered as a flexible manufacturing method with the potential for substantial innovations in fabricating geometrically complicated structured polymers, metals, and ceramics parts. Among them, polymeric composites show versatility for applications in various fields, such as constructions, microelectronics and biomedical. However, the poor resistance of these materials against fire must be considered due to their direct relation to human life conservation and safety. In this article, the recent advances in the fire behavior of 3D-printed polymeric composites are reviewed. The article describes the recently developed methods for improving the flame retardancy of 3D-printed polymeric composites. Consequently, the improvements in the fire behavior of 3D-printed polymeric materials through the change in formulation of the composites are discussed. The article is novel in the sense that it is one of the first studies to provide an overview regarding the flammability characteristics of 3D-printed polymeric materials, which will further incite research interests to render AM-based materials fire-resistant.
