چکیده :

Acrylonitrile-Butadiene-Styrene (ABS) is one of the most widely used materials for 3D printing technology that has the variety of positive specifications. However, it has some difficulties that limiting its use. This paper investigates the effect of Thermoplastic polyurethane (TPU) and Styrene-Butadiene-Styrene (SBS) to improve ABS properties in 3D filament manufacturing. We prepared samples with different weight percentages of ABS (60-95%wt.)/TPU(5-40%wt.) combination and after that, some SBS polymer (0.5-2%wt.) were added to the optimum mixture of ABS/TPU to improve the properties of final products. The compatibility of the polymers in the blends were confirmed by FTIR studies. Variations in functional parameters like printability, shrinkage, cracks between layers, nozzle and bed temperature were studied. According to the results obtained, due to good compatibility of ABS, TPU and SBS together, adhesive properties between layers and onto the building platform and in general, their printability are enhanced.
