One of the high-performance technologies for serial production small-sized metal and ceramic complex-profile parts is powder injection molding (PIM). The most industrially demanded types polymer binder in PIM technology are polyoxymethylene-based compositions wax-polyolefin mixtures. Despite large number studies devoted to different technology, actual task still a comparative analysis properties determine their advantages disadvantages, as well optimization used compositions. In this regard, study aims at thermophysical feedstocks with based on polyoxymethylene mixtures under condition using identical steel filler. specific heat capacity, temperatures, phase transitions, thermal inertia effective conductivity compared feedstocks, were determined result calculation-experimental study. obtained data can replenish knowledge bases necessary simulation modeling optimizing processes various products made 42CrMo4 steel. As powders, kinetic effects forming less significant than those analogs binder, which facilitates moldability. Thus, feedstock has significantly higher rate temperature field leveling binder. Because insignificant difference have 1.5 times approximately 20% filler form mixture. technological include possibility processing lower temperatures.

Fused filament fabrication (FFF) is the most widespread and versatile material extrusion (MEX) technique. Although powder-based systems have dominated metal 3D printing landscape in past, FFF’s popularity for producing parts (“metal FFF”) growing. Metal FFF starts from a polymer–metal composite feedstock proceeds through three primary stages, namely shaping (i.e., printing), debinding, sintering. As critically discussed present review, final quality of influenced by characteristics feedstock, such as loading, polymer backbone, presence additives, well processing conditions. The literature shows that diverse array metals, including steel, copper, titanium, aluminium, nickel, their alloys, can be successfully used FFF. However, formulation appropriate binders represents hurdle to adoption new systems. Meanwhile, intricate geometries are difficult fabricate due FFF-related surface roughness sintering-induced shrinkage. Nonetheless, comparison with other common AM techniques conducted herein suggests convenient option, especially prototyping small-scale production. Whilst providing insights into functioning mechanisms FFF, review offers valuable recommendations, facilitating broader uptake across various industries.
