Laser technologies for fast prototyping using metal powder-based materials allow for faster production of prototype constructions actually used in the tooling industry. This paper presents the results of measurements on the surface texture of flat samples and the surface texture of a prototype of a reduced-mass lathe chuck, made with the additive technology—powder bed fusion. The paper presents an analysis of the impact of samples’ orientation on the building platform on the surface geometrical texture parameters (two-dimensional roughness profile parameters (Ra, Rz, Rv, and so on) and spatial parameters (Sa, Sz, and so on). The research results showed that the printing orientation has a very large impact on the quality of the surface texture and that it is possible to set digital models on the building platform (parallel—0° to the building platform plane), allowing for manufacturing models with low roughness parameters. This investigation is especially important for the design and 3D printing of microelectromechanical systems (MEMS) models, where surface texture quality and printable resolution are still a large problem.

316L钢粉末床熔合技术中印刷方向对表面织构参数的影响。

使用基于金属粉末的材料进行快速原型制作的激光技术可以更快地生产实际在工具行业中使用的原型结构。本文介绍了使用添加技术（粉末床熔合）制成的扁平样品表面纹理和质量减轻的车床卡盘原型的表面纹理的测量结果。本文分析了样品在建筑平台上的方向对表面几何纹理参数（二维粗糙度轮廓参数（Ra，Rz，Rv等）和空间参数（Sa，Sz）的影响。， 等等）。研究结果表明，印刷方向对表面纹理的质量有很大影响，并且可以在建筑平台上设置数字模型（与建筑平台平面平行-0°），从而可以制造具有以下特征的模型：低粗糙度参数。这项研究对于微机电系统（MEMS）模型的设计和3D打印尤其重要，因为微机电系统模型的表面纹理质量和可打印分辨率仍然是个大问题。
