Evaluación Del Comportamiento Mecánico De Empalmes Japoneses Utilizados En Carpintería Aplicados A Impresión 3D Por Fdm

Abstract

3D printing has revolutionized manufacturing processes, but limitations in the size of 3D printed parts have prompted the search for efficient solutions for the assembly of large components. In this context, the adaptation of traditional Japanese joints to 3D printing technology using the fused deposition molding (FDM) process has been explored, with the aim of developing strong and reliable joints to overcome the current limitations. Through computational simulations in ANSYS, three types of joints (Dovetail, Notched and Scarf) were evaluated under bending load, following the ISO-178 standard. The results revealed that the Notched joint presented a better stress distribution, the Scarf showed greater uniformity, although with considerable displacements, and the Dovetail showed high stress concentrations. Based on these findings, a new combined splice was designed that integrates the advantages of the previous designs, achieving a more efficient stress distribution and reducing displacements. This study demonstrates the potential of Japanese splices adapted to 3D printing as a viable solution for the assembly of large parts, offering a robust and efficient alternative for additive manufacturing.
