“…It is natural that 3D surface topography measurements carry more information than 2D profile measurements. In the process of verifying the surface topography parameters, contact [38][39][40] and optical measurement methods [41][42][43][44] are used.…”

One of the key measurement parameters of the surface topography is the measurement area. It inﬂuences the possibility of using ﬁlters separating components of surface texture and thus determines the reliability of the obtained measurement results. The currently applicable standard does not deﬁne the size of the measuring area. To determine its size, fractal analysis was carried out in the article. The paper presents research on two types of geometry: simple geometry in the form of cylindrical and spherical surfaces and more complex geometry represented by free surfaces such as crowns and molars of teeth. In the process of making the research models, four 3D printing techniques were used: Fused Deposition Modeling (FDM), Melted and Extruded Modeling (MEM) Fused Filament Fabrication (FFF) and Material Jetting (MJ). 3D measurements of surface texture were made using a contact proﬁlometer and a focus variation microscope. The analysis of topography images and selected parameters of the surface topography showed that the optical method gave better measurement results than the contact method. In the case of models made with the FDM and MEM techniques, similar values of the Sa parameter were obtained. Slightly smaller values of Sa were recorded for FFF models, while the highest for MJ models. Models made using the FFF method were also characterized by the lowest variability of results. Models made using the MJ method were characterized by relatively deep valleys in comparison with the other models, which was reﬂected in the Ssk and Svk parameters. The valleys counting from the top surface of the specimen were the shallowest for models made with the FFF method. Surfaces with simpler geometry were characterized by smaller variability of parameters values.

“…Thus far, the application of 3D-printing technology to produce wax injection dies, and their analysis, have not been widely discussed in leading scientific journals. In 2020, the articles [19,20] presented an analysis of the surface topography of injection die made with PolyJet technology using a profilometer. The authors also analyzed the relationship between the surface parameters and the number of wax injections.…”

The investment casting method supported with 3D-printing technology, allows the production of unit castings or prototypes with properties most similar to those of final products. Due to the complexity of the process, it is very important to control the dimensions in the initial stages of the process. This paper presents a comparison of non-contact measurement systems applied for testing of photopolymer 3D-printed injection die used in investment casting. Due to the required high quality of the surface parameters, the authors decided to use the DPP (Daylight Polymer Printing) 3D-printing technology to produce an analyzed injection die. The X-ray CT, Structured blue-light scanner and focus variation microscope measurement techniques were used to avoid any additional damages to the injection die that may arise during the measurement. The main objective of the research was to analyze the possibility of using non-contact measurement systems as a tool for analyzing the quality of the surface of a 3D-printed injection die. Dimensional accuracy analysis, form and position deviations, defect detection, and comparison with a CAD model were carried out.
