In this article, we will explore the factors that affect the smoothness of 3D printed parts and how you can achieve high levels of smoothness. Although 3D printing is usually a layer-by-layer process, additive manufacturing technologies are capable of printing relatively smooth surfaces. However, the smoothness of finished 3D printed parts depends on the printing process, the material, the post-processing operations and other secondary factors that will be related in this article.
