Evaluation of directional mechanical properties of 3D printed polymer parts

In this study, we evaluated the effect of material properties for addictive direction manufacturing by Three-dimensional printing (3DP). The fused deposition modeling (FDM) is one of the most commonly employed 3DP methods. Tensile tests at ordinary temperatures were carried out on materials consisting of polylactide. Addictive direction of the tension specimen with different addictive direction was fabricated by FDM equipment. We implemented tensile test with the specimen to measure material properties of the specimen and researched mechanical properties of the specimen with the volume filled capacity. The ultimate stress of the vertical direction stack was highest in the other directions of tension specimen manufactured by FDM. The ultimate stress of Specimen of volume 100% filled capacity is approximately 20% larger than specimen of volume 10% filled capacity.
