Solid composites used in material extrusion additive manufacturing have experienced considerable expansion over the past 5 years, incorporating functional properties into 3D‐printed objects. This paper presents a systematic review that aims to: (I) analyze the current state of development in the field; (II) quantify and categorize the adopted polymeric matrices, reinforcing materials, feedstock shapes, characterization strategies, and extrusion mechanisms; and (III) identify the applications, limitations, and trends for future research. The PRISMA statement was followed and the databases Scopus, Web of Science, and PubMed were consulted. Among the 116 included studies, the use of customized filaments surpassed the commercially available ones, with particulate matter being the most common form of filler when melt‐mixed with the polymer. Polyamide is the most widely adopted matrix (30.3%), followed by PLA (22.0%) and ABS (17.4%). In terms of reinforcements, carbon fiber (32.4%), glass fiber (12.5%), and ceramics (12.5%) compose the podium as the most frequently used, with nanofillers receiving increasing attention. In the conducted analysis, no standardized protocols were identified that clearly encompassed the entire process from feedstock formulation to technical prototype fabrication. At last, recycling, exploration of biodegradable materials, and 4D printing were identified as the main opportunities for future research.Highlights Reinforced polymers enable the enhancement of properties for 3D‐printed parts. Composite feedstock is usually formulated and mixed before printing. 3D printers with filament‐ or screw‐based extrusion mechanisms have been used. Mechanical and morphological analyses are common in material characterization. No identified applications were employed in real‐world scenarios.

“…All these issues cause acute inaccuracy or even failure in printing; therefore, in recent years, several research studies have focused on improving the printability of PP by decreasing the crystallinity of the polymer. This can be achieved through different strategies such as the addition of fillers (such as, carbon fibers [ 21 ], glass fibers [ 22 , 23 ], clay [ 24 ], talc [ 23 ] or cellulose [ 25 ]) or the use of polymeric blends and of copolymers [ 26 ]. In previous works, it was demonstrated that the addition of 20 wt% of talc in a PP-PE random copolymer leads to more pronounced non-Newtonian behavior compared to neat PP, and therefore to enhanced FFF printability.…”

In this study, a nanocomposite based on a heterophasic polypropylene copolymer containing 5 wt% of nanoclays and 3 wt% of compatibilizer was formulated via melt compounding to obtain a material suitable for Fused Filament Fabrication (FFF) processing with enhanced flame-retardant properties. From rheological analyses, the nanocomposite showed an important increase in the non-Newtonian behavior, and, therefore, improved FFF printability compared to the pristine PP COPO. A filament with suitable characteristics for FFF was produced using a single-screw extruder and subsequently 3D printed. Finally, cone calorimeter and UL94 tests were carried out on both 3D-printed and compression-molded specimens. The obtained results showed that the 3D-printed samples exhibited even better flame-retardant properties than the compression-molded ones, thus demonstrating not only the possibility of successfully developing and using functionalized PP-based filaments in 3D printing but also the possibility of obtaining enhanced flame-retardant properties compared to conventional compression molding.
