ABS/Silicon Dioxide Micro Particulate Composite from 3D Printing Polymeric Waste

Abstract

In this paper, Acrylonitrile-Butadiene-Styrene matrix composites reinforced with Nano-silica dioxide particles were examined and prepared to study their mechanical properties. The composite sheets were pre-prepared using the hot extrusion process. Due to its wide characteristics, silica dioxide additions can strengthen the usability and mechanical features of composite thermoplastics and polymers. Furthermore, introducing silica dioxide as a filler in various attributes can help to maintain the smooth flow of sufficient powders, reduce caking, and manage viscoelasticity. Despite its advantages, 3D printing generates a significant amount of waste due to limited prints or destroyed support structures. ABS is an ideal material to use because it is a thermoplastic and amorphous polymer with outstanding thermal properties that is also applicable with the FFF (Fused Filament Fabrication) technique. The findings showed that increasing the silica dioxide content reduces the tensile strength to 22.4 MPa at 10 wt%. Toughness, ductility, and yield stress values of ABS/silica dioxide composites at 15 wt% increased, indicating that the composite material reinforced by the silica dioxide particles improved material characteristics. It is essential to consider the impact of recycling in polymer reinforcement with fillers. Furthermore, the improved mechanical qualities of the composite material encourages successful ABS recycling from 3D printing, as well as the possibility of reusing it in a similar application.

Carbon Fiber/PLA Recycled Composite

“…Figure 15 presents the Ultimate Strength of the produced samples. It has been shown that the ultimate strength of the CF/PLA bends increased with the increase of the CF contents, with an increase from 7% to 28% for the CFRP at 10% and 20% contents, respectively, in comparison to the recycled PLA [ 95 ]. On the other hand, it is shown that the CFRP/PLA ultimate strength increased slightly concerning the recycled PLA, but it has a lower level than the CF/PLA blends, which is ascribed to the presence of the expired impregnated epoxy, as clarified before.…”

“…The trends of the ductility of the composite blends, i.e., the strains recorded at the point of failure during the tensile testing procedure, have been graphically plotted in Figure 16 . It has been observed that the recycled PLA ductility has a higher strain (6.01%) at the failure point in comparison with the commercial PLA filament (5.2%), with an increase of around 15% in ductility due to the degradation of the recycled properties during the recycling process [ 95 ]. Moreover, clear evidence illustrates that the CF/PLA composite suffered from a remarkable drop in ductility ranging from 43% to 30% for the 10% and the 20% CF reinforcement, respectively, which is attributed to the impact of the carbon fiber reinforcement.…”

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 ]…”

Developing an electric keyboard cleaner as an innovative alternative design

“…Numerous qualities of the copolymer composed of acrylonitrile, butadiene, and styrene include low weight, ease of formability, resistance to abrasion [20]. In the manufacture of car components, sports equipment, and toys such as Lego blocks often rely on ABS as the material used [21] and listed in Table A4 (see Appendices).…”
