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

Area of Science:

• Materials Science
• Polymer Science
• Nanotechnology

Background:

• Acrylonitrile-Butadiene-Styrene (ABS) is a versatile thermoplastic polymer widely used in 3D printing.
• 3D printing processes, particularly Fused Filament Fabrication (FFF), often generate significant waste.
• Incorporating nano-silica dioxide into polymer matrices can enhance mechanical properties and processability.

Purpose of the Study:

• To investigate the effect of nano-silica dioxide reinforcement on the mechanical properties of ABS composites.
• To evaluate the potential of these enhanced ABS composites for recycling in 3D printing applications.

Main Methods:

• ABS matrix composites were prepared using the hot extrusion process.
• Nano-silica dioxide particles were incorporated as reinforcing fillers at varying weight percentages.
• Mechanical properties, including tensile strength, toughness, ductility, and yield stress, were systematically evaluated.

Main Results:

• Increasing nano-silica dioxide content initially reduced tensile strength, reaching 22.4 MPa at 10 wt%.
• At 15 wt% nano-silica dioxide, toughness, ductility, and yield stress of the ABS composites significantly increased.
• The addition of silica dioxide improved the overall mechanical characteristics of the ABS composites.

Conclusions:

• Nano-silica dioxide reinforcement can effectively enhance the mechanical performance of ABS composites.
• The improved properties facilitate the successful recycling of ABS materials from 3D printing waste.
• These reinforced composites hold potential for reuse in similar applications, promoting a circular economy in additive manufacturing.
