“…Additive manufacturing (AM), or 3D printing, offers several advantages, including acceptable accuracy, cost-effectiveness, and most importantly, the ability to fabricate complex shapes. R. Surya Teja et al [ 1 ] demonstrated this ability by printing a reduced-size replica of the Eiffel Tower. The most common 3D printing technology is Fused Deposition Modelling (FDM), which is now used to fabricate industrial and functional parts for applications in various sectors, including medical, automotive, aerospace, defence, and consumer goods.…”

“…With regard to the rapidly growing applications in the industrial world, post-consumer recycled polymers can be used as raw materials for new products, including 3D printing filaments. 3D printing, also known as additive manufacturing, creates physical objects by building material layers based on digital design [43]. 3D printing works based on the design of digital 3D models created using computer-aided design (CAD) software, or it can also be from a 3D scanner.…”

3D printing technology is rapidly developing in the manufacturing industry in producing complex and easily adjustable three-dimensional objects using the help of controls from computers. Behind its advantages, the 3D printing process requires filaments from virgin polymers which generally have a high price and adversely affect the environment. Post-consumer polymer recycling is a substitute material solution from virgin polymers and is environmentally friendly so as to support the realization of a circular economy. Studies on 3D printing filaments from post-consumer polymers have been discussed in this article, especially for filaments derived from acrylonitrile butadiene styrene (ABS), polylactic acid (PLA), and polyethylene terephthalate (PET). In addition, this article also reviews the sources of recycled raw materials, difficulties during the process, mechanical properties, thermal properties and efforts to improve the quality of 3D printing products. The results show that recycling post-consumer polymers for 3D printing filament applications is a promising approach to reducing the environmental impact of 3D printing while still retaining the mechanical properties and printability of filaments. This article provides insight into several studies that address the development of 3D printing using post-consumer polymer materials.

The 3D printing of continuous-fiber composites is currently relevant to engineers and researchers. This study aims to characterize and predict the mechanical properties of Onyx/glass fiber specimens printed using 3D printing. The work assesses the impact of glass fiber printing parameters on the mechanical behavior of printed parts and proposes analytical and numerical methods to predict mechanical properties. A physicochemical analysis was conducted on 3D printed continuous glass fibers. The study also investigated the impact of fiber printing parameters on composite parts. The results indicate that the 3D-printed glass fibers consist of nylon, continuous glass fibers, and voids (porosity), which range from 58% to 63%, 31% to 38%, and 5% to 8%, respectively. Mechanical characterizations indicate that printing fiber layers in blocks results in superior mechanical properties compared to printing alternating layers of glass fibers and Onyx. Additionally, the concentric mode of fiber printing can be challenging if the ‘start rotation’ parameter is not adjusted correctly. Premature specimen breakage occurred when fiber printing began within their useful length, resulting in a deformation at break that was approximately 34% less, depending on the starting position. The proposed analytical and numerical prediction methods had prediction errors of approximately 7% to 12% and 5% to 7%, respectively. Engineers can use these prediction approaches during the dimensioning phase of 3D printed composite parts.
