Designing for strength: enhancing mechanical performance through structured patterns in 3D printed elastomer

Abstract

The mechanical performance of 3D printed elastomers is a crucial factor for their successful utilization in various applications, including soft robotics, wearable devices, and biomedical engineering. This study focuses on investigating the influence of different structured patterns, namely vertical and crosswise vertical SC, on the strength and mechanical performance of 3D printed elastomers. Through a series of experimental tests and numerical simulations, it was found that the cross-shaped structure exhibited the best strength among the tested patterns. This enhanced performance can be attributed to the unique arrangement of the crosswise structure, which effectively distributes stress and reduces strain concentration. This study provide valuable insights into the design and fabrication of high-performance 3D printed elastomers, paving the way for the development of advanced materials and devices with enhanced mechanical properties.
