One of the most popular methods for manufacturing new products is FDM (Fusion Deposition Modeling). In which two segments are established: industrial and desktop. The latter group has had notable growth in recent years. One of the disadvantages found in this method is its surface finish, which presents a remarkable roughness. In this research work, the correlation that exists in the printing configuration’ parameters and the resulting roughness analyzed by means of the ISO 4287-1997 standard will be analyzed. The configuration parameters to take into account are: layer height, printing speed. The materials to be analyzed are: PLA, PET-G, ASA, Wood Filament, TPU. Besides, the equipment used is a Prusa brand desktop printer with the manufacturer’s software. What is more, the acceleration, extruder temperature and bed recommended in the software are used for each material. Hence, the constant printing characteristics are: perimeter thickness, 10% infill, extrusion diameter 0.4 mm. The objects to be evaluated are printed and the roughness on the walls of the Z axis, base plane and upper plane is measured. This analysis was carried out by means of the correlation by the use of the analysis of variance ANOVA. The printing speed does not affect the resulting surface roughness in any plane, while the layer height only shows a significant correlation ( < 0.05) with the roughness of the lateral plane of the samples.

制造新产品最流行的方法之一是 FDM（Fusion Deposition Modeling）。其中建立了两个部分：工业和桌面。后一组近年来有显着增长。这种方法的缺点之一是其表面光洁度，呈现出显着的粗糙度。在这项研究工作中，将分析存在于打印配置参数中的相关性以及通过 ISO 4287-1997 标准分析的结果粗糙度。要考虑的配置参数有：层高、打印速度。要分析的材料有：PLA、PET-G、ASA、Wood Filament、TPU。此外，所使用的设备是带有制造商软件的 Prusa 品牌桌面打印机。更重要的是，加速度，软件中推荐的挤出机温度和床被用于每种材料。因此，恒定的印刷特性是：周长厚度、10% 填充、挤出直径 0.4 毫米。打印要评估的对象，并测量 Z 轴、基准平面和上平面的壁上的粗糙度。该分析是通过使用方差分析的相关性进行的。印刷速度不影响任何平面的表面粗糙度，而层高仅与样品横向平面的粗糙度显着相关（<0.05）。测量底平面和上平面。该分析是通过使用方差分析的相关性进行的。印刷速度不影响任何平面的表面粗糙度，而层高仅与样品横向平面的粗糙度显着相关（<0.05）。测量底平面和上平面。该分析是通过使用方差分析的相关性进行的。印刷速度不影响任何平面的表面粗糙度，而层高仅与样品横向平面的粗糙度显着相关（<0.05）。
