Characterization and Sustainability Potential of Recycling 3D-Printed Nylon Composite Wastes

Abstract

The revolution of 3D-printing technology has caused an additional source of plastic waste, especially the new generation of composite filaments that are linked with the commercial fused deposition modeling process, adding pressure to find a sustainable solution to tackle the emerging waste problem. This study aims to investigate the mechanical and thermal properties of a blended recycled composite material produced by mixing two different 3D-printed reinforced composite wastes, carbon fiber CF/nylon, and glass fiber GF/nylon filaments that were mixed at different percentages using a hot extrusion procedure, tested by a tensile testing machine, and processed with five different weight ratios to study the impact of blend ratios on the material characteristics of the recycled composites and to find the optimum weight ratios with the most preferred properties. The results revealed that the maximum tensile strength of the GF/nylon composite was achieved with 60 wt%. The highest elastic modulus value was recorded at 60 wt% GF/nylon. Moreover, it was noted that at 80 wt% of GF/nylon, the ductility is at the peak value among the composites.

Comparative Experimental Investigation of Biodegradable Antimicrobial Polymer-Based Composite Produced by 3D Printing Technology Enriched with Metallic Particles

“…Furthermore, the use of 3D printing technology for the preparation of antimicrobial polymeric composites could enhance their characteristics and performance through the consistent extrusion process. Therefore, this technology may be helpful for further investigations and applications in the biomedical, food, space, and textile fields, as well as other science and technology applications like recycling of waste materials [ 112 , 113 , 114 ] and implementing nanotechnology for better performance [ 115 ]…”

A Comparative Investigation of the Reliability of Biodegradable Components Produced through Additive Manufacturing Technology

“…A computational approach was presented to model damage in the context of the linear material behavior exhibited by 3D-printed components [ 35 ]. The approach involves extracting a unit cell from the microstructure of a single layer of the printed parts, commonly known as the representative volume element.…”

“…They observed the best mechanical properties at 300 mm layer thickness and 0-degree raster angle. P. Biswas et al [ 35 ] developed a computational model based on the microstructure of 3D-printed ANS polymers to examine the orthotropic elastic characteristics utilizing micromechanics of a representative volume element (RVE) approach. Sunil Bhandari et al [ 36 ] developed a homogenized and linear elastic continuum FEA model in which the simulation was carried out to homogenize the cellular structure.…”

The Development of Sustainable Polyethylene Terephthalate Glycol-Based (PETG) Blends for Additive Manufacturing Processing—The Use of Multilayered Foil Waste as the Blend Component

“…The developed concept of polymer waste management using a 3D printing method is a relatively new idea and results mainly from the growing interest in new additive manufacturing techniques [ 43 , 44 , 45 , 46 , 47 ]. In last few years, some similar research topics concerned the utilization of FDM printing process wastes, which mainly concerns the modification of various types of PLA filaments [ 48 , 49 , 50 ].…”
