The paper deals with the investigation of 3D digitizing of small parts specifically by optical 3D scanner GOM ATOS TripleScan. The paper shortly illustrates the general concept of Reverse Engineering, which includes also the 3D scanning. The paper also describes the optical 3D scanner GOM ATOS TripleScan and a three-dimensional model obtaining procedure by means of this scanner. In the main part of the paper the concrete 3D scanning process of chosen individual objects is described (clips, ball nose end mill, screw drill, coin). Their shape and size were specific and distinct, therefore it was possible to test and compare particular digitizing attributes. The problems that occurred during 3D digitizing of individual parts are step by step discussed and solved.

This article focused on comparing of the properties of the two most used materials, Acrylonitrile-Butadiene-Styrene (ABS) and Polylactic Acid (PLA), in the Rapid Prototyping (RP) process using the Fused Deposition Modeling (FDM) method. The thin-walled components were manufactured by Zortrax M200 and DeeGreen 3D printer. Print settings and printer parameters are also mentioned in the article. The printed models were 3D digitized using the GOM ATOS Triple Scan II optical 3D scanner. Main section is focused on the analysis of individual components in the GOM Inspect software. Authors used this software to measure the individual distances. The last section of the paper focuses especially on the evaluation of obtained results in the form of tables and a chart.

Abstract. The article is focused on research of the influence of the layer thickness in the Fused Deposition Modeling (FDM) additive manufacturing method on shape geometrical and dimensional accuracy of parts. The digital model of the object (upper teeths) was obtained by intraoral 3D scanner 3Shape TRIOS used in dentistry. Based on the 3D (Three Dimensional) scanned digital model, the manufacturing of the upper teeths was realized on the FDM 3D printer Zortrax M200. The parts were manufactured in three different layer thicknesses. The manufactured parts was digitized by optical 3D scanner GOM ATOS Triple Scan. The dimensional and shape accuracy of the parts was evaluated in the software GOM Inspect.

The paper shortly illustrates the general concept of Reverse Engineering, which includesalso the 3D scanning. In the main part of the paper the concrete 3D scanning process of chosen individual objects are described. The problems that occurred during 3D digitizing of individual parts are step by step discussed and solved. The paper deals with 3D scanning of ball nose end mills and screw drill. The article gives a procedure for digitizing and comparing the results of the scanned digital models of the two ball nose end mills and screw drill.
