“…Superior mechanical properties are exhibited by the carbon fiber composites, while the jute fiber composites come from plants. [27,28] The test specimens were printed along the X-axis, which is similar to the orientation of the arrangement of fiber. The flexural characteristics of the additive manufactured continuous fiber composites have been evaluated by tensile experiment thereby comparing with Polylactic Acid matrix resin's performance.…”

Additive manufacturing is accelerating in hypersonic speed, which touched upon almost all the nook and corners of the manufacturing sector. The present stage wherein a 3D printer is capable of printing queer hybrid materials was not imagined through conventional manufacturing albeit it is meager existence in a few instances. Its expendable arms stretch to the maximum level that is even clearly addressed in Industry 4.0 too, by making at least a printer in a company for printing specific customized materials. The dream of printing composite material was been a long‐term goal for researchers worldwide. This article primarily focuses on this niche area of printing natural fiber composite materials that too specifically jute fiber‐reinforced composites. Very few pieces of literature are available on additive manufacturing of specific natural fibers. As the technique for printing natural fiber‐reinforced composites is still under evolution, this study will be more interesting as it consolidates the facts and figures involved in 3D of jute fiber reinforced composites alone. Different forms of jute fibers used by the researchers include weaved jute, jute as continuous fiber, filament along with jute, jute fiber as reinforcement, jute used as rope as well as jute fiber as cement matrix and all these forms have been addressed in this review.

Maxillofacial defects, arising from trauma, oncological disease or congenital differences, detrimentally affect everyday life. Prosthetic repair offers the aesthetic and functional reconstruction with the help of materials mimicking natural tissues, among which polymers take unprecedented role. The three-dimensional (3D) printing techniques based on the computer-aided design, where polymers are essential, provide a rapid and cost-effective workflow protocol to perfectly restore patient-specific anatomy for prosthetics. This review discusses the main 3D printing approaches to maxillofacial prostheses fabrication: extrusion and lithography, which are radically preferable to the traditional methods. The main assessment criteria, affording the polymer implementation in 3D printing of prostheses, as well as the characteristics of the key advanced polymers, are considered. The success of the prosthesis is shown to be largely dependent on the retention system, predominantly using polymers in the form of adhesives and osseointegrated implants as a support for the prosthesis. The approaches and technological prospects are also discussed in the context of specific aesthetic restoration on the example of the nasal, auricle and ocular prostheses. 3D printing techniques determine the development of personalized approaches to improve aesthetic and functional effect of prosthetics in patients with maxillofacial defects.

“…Depending on the form of material and the type of extruder, extrusion-based AM can be divided into filament fused fabrication (FFF) and fused granular fabrication (FGF), among others [ 2 ]. FFF uses high-quality, not too brittle or too flexible filament with a specific and constant diameter [ 3 ]. So, only certain materials with the appropriate mechanical properties can be processed by FFF.…”

Polylactic acid (PLA) is a biodegradable polymer that can replace petroleum-based polymers and is widely used in material extrusion additive manufacturing (AM). The reprocessing of PLA leads to a downcycling of its properties, so strategies are being sought to counteract this effect, such as blending with virgin material or creating nanocomposites. Thus, two sets of nanocomposites based respectively on virgin PLA and a blend of PLA and reprocessed PLA (rPLA) with the addition of 0, 3, and 7 wt% of titanium dioxide nanoparticles (TiO2) were created via a double screw extruder system. All blends were used for material extrusion for 3D printing directly from pellets without difficulty. Scanning electron micrographs of fractured samples’ surfaces indicate that the nanoparticles gathered in agglomerations in some blends, which were well dispersed in the polymer matrix. The thermal stability and degree of crystallinity for every set of nanocomposites have a rising tendency with increasing nanoparticle concentration. The glass transition and melting temperatures of PLA/TiO2 and PLA/rPLA/TiO2 do not differ much. Tensile testing showed that although reprocessed material implies a detriment to the mechanical properties, in the specimens with 7% nano-TiO2, this effect is counteracted, reaching values like those of virgin PLA.
