| Summary: | Additive manufacturing enables rapid and cost-effective production of prototypes and final products, with Fused
Deposition Modeling (FDM) being widely used due to its accessibility and low material costs. This study addresses a
key research gap by analyzing the mechanical and thermal properties of 100% recycled ABS printed using an
open-source FDM 3D printer. Unlike prior research focusing on blended materials or reinforcement techniques,
this study evaluates the standalone performance of recycled ABS, offering insights into its viability for sustainable
manufacturing. Recycled ABS filament was produced through mechanical recycling and used to fabricate test
samples. Microstructural analysis of fractured samples in X, Y, and Z orientations revealed voids and pores in
recycled ABS, while standard ABS exhibited air bubbles in specific orientations. Impact testing per ASTM D256
showed that recycled ABS had an impact strength of 154.67 J/m, significantly lower than the 383.31 J/m of
standard ABS. Differential Scanning Calorimetry analysis indicated a glass transition temperature (Tg) of 100.14°C
for recycled ABS, compared to 104.97°C for standard ABS, demonstrating relative thermal stability. While 100%
recycled ABS exhibits reduced mechanical properties and impact strength, its thermal performance remains stable.
This study comprehensively evaluates recycled ABS filament for FDM printing, highlighting its potential for
sustainable manufacturing by minimizing material waste. The findings contribute valuable data on the feasibility of
upcycling polymer waste for functional 3D-printed products, offering insights into the challenges and opportunities
of integrating recycled ABS in green additive manufacturing. |
