Abstract
The aim of this work was to gain an initial impression of the surface quality that can be achieved with additively manufactured ceramic components. For this purpose, an assessment body was generated, which has partially double-curved surfaces that can be scanned using a confocal microscope. After manufacturing using Vat Photopolymerization for ceramic components (CerAM VPP) with a commercial alumina suspension (Lithalox 350, Lithoz, Vienna, AUT) and thermal processing, the respective surface was measured at four different geometric areas. For evaluation, line sections were extracted to calculate Ra values as well as to determine Sa values for surfaces. Ra and Sa values were determined in all areas, reaching always values below 2.5 μm. The surface quality is therefore an order of magnitude lower than that of typical metallic AM components.
这项工作的目的是初步了解快速成型陶瓷部件的表面质量。为此,我们制作了一个评估体,该评估体具有部分双曲面,可使用共聚焦显微镜进行扫描。在使用商用氧化铝悬浮液(Lithalox 350,Lithoz,Vienna,AUT)和热处理工艺进行陶瓷部件(CerAM VPP)的大桶光聚合制造后,在四个不同的几何区域测量了各自的表面。为了进行评估,提取了线段来计算 Ra 值和确定表面的 Sa 值。所有区域的 Ra 值和 Sa 值均已确定,其值始终低于 2.5 μm。因此,表面质量比典型的金属 AM 组件低一个数量级。
