Abstract
FDM technology (Fused Deposition Modeling) is a popular form of additive manufacturing of elements. The development of this technology is related to the need of achieving high accuracy of products and shortening the time of manufacturing. Despite the through of advantages, FDM technology involves several technological problems. One of them is the phenomenon of detaching created element from the bed of the device as a result of processing shrinkage. One of the methods of increasing the adhesion of elements to the bed is the use of glued intermediate materials. Among the available options, there are tapes dedicated to FDM technology, such as adhesive pads. In addition, they are used Kapton and cheaper, cellulose tapes. The article presents the method of testing the adhesion force between element and bed of the device producing in FDM technology and obtained values for the use of various types of intermediary materials. The specimens were made of one of the most commonly used material - PLA. A glass bed was used for the test. The results were compared with values of adhesion force for elements produced on a smooth, uncoated bed. The method and research results allow to compare and select the appropriate method based on empirically determined values.

On the basis of experimentally obtained values of adhesion forces, it is possible to compare the effectiveness of using different types of tapes
Summary
Fused Deposition Modeling technology is a popular method of incremental manufacturing components. This technology consists in applying layer-by-layer of previously plasticized material. The material is extruded through the nozzle onto the bed of the device, after which it congeals in a shape consistent with the digital spatial model [1-3]. Simplicity of operation and low cost of operation, devices manufacturing in FDM technology have found application in various fields of science and technology [4,5]. Details are often elements of visualization or verification of projects. They are used to create tooling patterns and molds [6]. The wide possibilities of building prototypes and target devices affect the continuous development of this method [7,8]. Despite the above-mentioned advantages, FDM technology is associated with several technological problems
