Abstract

Additive Manufacturing (AM) is a technology for printing three-dimensional objects from three-dimensional model data. It has been enhanced to minimise production costs. The most widely used additive manufacturing process is fused deposition modelling, which extrudes models layer by layer using a thermoplastic filament. It is becoming increasingly important and plays a significant role in the manufacturing of multifunctional product nowadays. When selecting the proper material for 3D printing, it is necessary to consider the intended usage of the material. The appropriate material selection is critical to ensuring the product's durability and strength. The goal of this study was to assess the strength of a thermoplastic material chosen for comparison, which is Acrylonitrile Butadiene Styrene (ABS) that is made by various companies. Specimens were manufactured using thermoplastic filament and submitted to tensile and compression tests to see whether different manufacturers have an effect on the strength. All printed specimens were ensured to have the same parameters for printing process to avoid interfering with the testing results. The ABS material's strength was determined by the way each specimen reacted and the highest load that the specimen could withstand during compression and tensile tests. The data indicate that different manufacturers have an effect on the ABS material's strength. The methodologies used in this study are sufficient to demonstrate the strength comparison of ABS material manufactured by various manufacturers.
