Adhesion between the bed and component manufactured in FDM technology using selected types of intermediary materials

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.
