Additive Manufacturing (AM) is gaining prominence due to its massive advantage in fabricating components without any geometrical limitations. The most widely used AM technique is Fused Deposition Modelling (FDM). FDM is an extrusion-based AM mostly focused on producing functional prototypes and in some cases as an end-product. One of the most common challenges associated with FDM is its reduced dimensional accuracy and surface quality. A fair amount of research has been carried out to identify the factors affecting print quality and measures to reduce surface roughness. On a few occasions, it is still necessary to achieve higher precision and quality to meet the standards set by conventional manufacturing. Hence, post-processing is employed as an additional step to reach the finish required. This paper focuses on enhancing the surface quality of FDM parts by subjecting it to Acetone vapour smoothening, Shot-blasting and Laser-assisted finishing post-processing methods. A compara...

不同后处理方法对熔融沉积建模样品表面形貌的影响

增材制造(AM)由于其在制造部件方面的巨大优势而不受任何几何限制,因此日益受到关注。最广泛使用的AM技术是熔融沉积建模(FDM)。FDM是基于挤压的增材制造,主要致力于生产功能原型,在某些情况下还作为最终产品。与FDM相关的最常见挑战之一是其尺寸精度和表面质量降低。为了确定影响打印质量的因素以及减少表面粗糙度的措施,已经进行了大量研究。在某些情况下,仍然有必要达到更高的精度和质量,以满足常规制造所设定的标准。因此,采用后处理作为达到所需精加工的附加步骤。本文通过对FDM零件进行丙酮蒸气平滑,喷丸和激光辅助精加工后处理方法来提高FDM零件的表面质量。比较
