Abstract

Additive Manufacturing (AM) is a process that deposits materials on a platform to form 3D objects layers by layers. One of the downsides of AM is wastage generated during the printing process. Acrylonitrile Butadiene Styrene (ABS) is a popular material used in AM for thermoplastics. This study focused on the feasibility of using 100% recycled ABS for the 3D printing process via Fused Deposition Modeling (FDM). The recycling process began by re-granulating the ABS waste and turning it into a new filament. Test specimens were printed using the new recycled filaments. The experiment was carried out on the mechanical properties of the test specimens, and comparison was made with the standard ABS specimens. The results showed that recycled ABS could be converted into filaments with an extruder conveyor temperature of 270°C and a travel speed of 18 mm/s. The results obtained for the mechanical properties of the recycled ABS, showed that it had decreased, resulting in a 32% reduction in the flexural strength of the printed material, while an 82% increase in the compression strength due to multiple recycling cycles. With the aid of ultrasound vibration, the results showed a 53% increase in flexural strength and a 59% increase in compression strength comparing between 0 kHz and 20 kHz frequency were applied. Overall, the approach to extrude 100% recycled ABS plastic is a viable option for better use of printed materials and, with the aid of ultrasound vibration, it helps to improve the mechanical properties of the recycled ABS
