Testing the methodology for evaluating the accuracy of the 3d printing

Abstract

Abstract The spread of 3d printing in the industry has led to the need to determine the accuracy of reproducible dimensions on a 3d printer. Precision manufacturing of parts is essential in the manufacture of products. The hardware manufacturer provides the user with information on the positioning accuracy of the 3d printer, but this could be a marketing statement. Also, it is very important to know the accuracy of a 3d printer after its upgrade or under the influence of various external factors (ambient temperature, vibrations) inherent in the location of the printer. The purpose of this work was to check the accuracy of a 3d printer and to develop a methodology for assessing the accuracy of a 3d printer by printing a sample product. As a result of the work done, it was found that by measuring various samples of products, it is possible to determine the quality of accuracy for certain structural elements and the average coefficient of accuracy of products. It was also found that the study of a sample product allows us to determine most of the factors affecting the accuracy of manufacturing products.
