Fused deposition modeling (FDM) is one of the most widely used 3D printing techniques that utilizes polymers to create models, prototypes or even end products. Since 2009, the demand for FDM has been increasing at an incredible rate from one year to the next, and many experts believe that this technology has the potential to revolutionize manufacturing in many sectors. The main advantages of FDM technology are that the technique offers a simpler fabrication process and a more cost-effective method compared to other prominent 3D printing techniques, and yet, it is still capable of manufacturing complex geometries and cavities with reasonable dimensional accuracy. However, there are still some limitations and shortcomings that have been identified, especially pertaining to the lower mechanical properties exhibited in FDM parts compared to the parts produced by conventional methods such as injection and compression techniques. Therefore, this review article focused on recent developments and progress in the FDM technique in an attempt to improve the end performance of 3D-printed parts, along with current challenges and the future direction.

熔融沉积建模（FDM）是最广泛使用的3D打印技术之一，该技术利用聚合物来创建模型，原型甚至最终产品。自2009年以来，对FDM的需求从一年到下一年一直以令人难以置信的速度增长，许多专家认为，该技术具有在许多领域掀起制造业革命的潜力。FDM技术的主要优点是，与其他著名的3D打印技术相比，该技术提供了更简单的制造工艺和更具成本效益的方法，然而，它仍然能够以合理的尺寸精度制造复杂的几何形状和腔体。但是，仍然存在一些局限性和不足之处，尤其是与通过传统方法（例如注射和压缩技术）生产的零件相比，FDM零件具有较低的机械性能。因此，本文将重点介绍FDM技术的最新发展和进步，以期改善3D打印部件的最终性能，以及当前的挑战和未来的方向。
