摘要:
The mechanical properties of fabricated parts by fused deposition modeling (FDM) are impaired by significant voids between deposition lines. In this study, a novel approach that adding thermally expandable microspheres into matrix and combining FDM process with thermal treatment was proposed to tackle the problem. The influences of microsphere content, heating temperature and heating time were investigated. The results show that appropriate conditions of thermal treatment exert a positive influence on mechanical properties. With the addition of 2 wt.% microspheres, tensile and compressive strength of samples heated at 140 degrees C for 120 s increase 25.4% and 52.2%, compared to untreated samples, respectively. A new process is developed to prepare foam materials based on FDM, which will have the potential applications in shoes industry. (C) 2016 Elsevier Ltd. All rights reserved.
