Design and Structural Analysis of a Support System for a 3d Printer

Abstract:

This paper presents the design and structural analysis of a support system for a 3D printer, developed to improve resin drainage by enabling rotational movement along two axes. Three design variants were created, and after evaluating their performance, the second variant was chosen for its higher torque capacity and potential for future enhancements. This variant showed the most promise in achieving the desired functionality while allowing for further optimization. Finite element analysis (FEA) was utilized to investigate the structural behavior of the support system under loading conditions, ensuring the design remained within the elastic range. The FEA simulations were performed using Beam, Solid, and Shell element types, which provided insights into stress and strain distribution within the structure. This analysis guided the design process, allowing for refinements that improved the structural integrity and load-bearing capacity of the support. Alongside FEA, analytical calculations were performed to assess the bending stress and shear forces on the aluminum profile under three-point bending conditions. These calculations confirmed that the support structure was capable of handling the operational loads while staying within the elastic domain, ensuring reliable performance. This study demonstrates the effectiveness of combining finite element analysis with analytical methods to optimize the design of 3D printer support systems. The results highlight the potential for enhancing the performance and efficiency of additive manufacturing processes through improved structural designs.
