熔融沉积成型是各种工程应用中使用最广泛的增材制造技术之一。本工作探讨了立方体的美学。在FDM印刷工艺中，在印刷物体，特别是圆柱形物体时面临的主要问题之一是熔融长丝的初始层不粘在热床上。在打印时还存在其他严重问题，它们在挤出下，从加热的打印喷嘴过度挤出长丝，在打印物体的顶层中出现间隙，从加热的喷嘴拉出或渗出额外的长丝，打印床过热，层移位，层分离和分裂，研磨长丝，堵塞挤出机，挤出机在打印过程中间停止，在这项研究中，上述问题通过Pareto分析观察和识别，在机器上，初步层与热床的不粘附发生得更多，从而提供解决方案来避免这个问题，这反过来又有助于减少打印3D物体时发生的各种其他问题。
Fused Deposition Modelling is one of the most widely used Additive Manufacturing technologies for various engineering applications. The present work investigated the aesthetics of the cube. In FDM process of printing, one of the major problems faced in printing the objects, specifically the cylindrical objects is the non-sticking of the preliminary layers of the molten filament on to the hot bed. There are other serious problems which occur while printing they are under extrusion, over extrusion of filament from heated printing nozzle, gaps occurring in the top layers of the printed object, stringing or oozing of the extra filament from the heated nozzle, overheating of print bed, Layer shifting, layer separation and splitting, grinding filament, clogged extruder, extruder stopping in the middle of printing process, gaps between infill and outline, etc. In this study, the above-mentioned problems are observed and identified through Pareto analysis that on the machine, the non-sticking of the preliminary layers to the hot bed occurred more, thus solutions are provided to avoid this problem which in turn has helped to reduce various other problems occurring while printing the 3D objects.
