Strength of A Chair Renovated With Additive Production Systems and Reverse Engineering Approach

Abstract

Furniture are items that provide convenience and comfort in daily works, and that are present in all areas of life. The furniture renovation process is of great importance for the protection of furniture and the maintenance of furniture’s function. Today, this process may include applications involving reverse engineering and additive production systems. The aim of this study is to provide guidance for amateur and professional workers in the field of furniture renovation about the use of reverse engineering approach and additive production systems in this field. In this study, missing details of a plywood chair were scanned with 3D scanners. Point clouds were obtained in STL format. These point clouds were converted into meaningful data and the missing details were printed out with the additive production system. Damaged areas of the chair were repaired with this method. The repaired chair sample and the original chair sample were subjected to static and dynamic strength tests, and the test results obtained from these samples were compared. As a result of these tests, the renovation work was found to be successful.
