Dynamic Mechanical Properties of Additively Manufactured Lattice Structures: A Comprehensive Review

Abstract

Additive manufacturing (AM) has revolutionized the production of lattice structures,
offering unparalleled design freedom and the ability to tailor mechanical properties for specific
applications. While extensive research has focused on the static mechanical properties of these
structures, their dynamic mechanical behavior under varying loading conditions is increasingly
gaining attention due to its relevance in critical applications such as aerospace, biomedical
implants, and energy absorption systems. The dynamic properties of AM lattice structures are
influenced by a combination of material properties, process parameters, geometric design, and
loading scenarios, presenting complex challenges in ensuring reliability and performance under
1
dynamic conditions. This paper provides a comprehensive review of the existing research on the
dynamic mechanical properties of additively manufactured lattice structures. The review is
conducted in three phases: defining the scope and key questions, systematically identifying, and
selecting relevant studies, and evaluating them using defined criteria. The findings highlight
significant research gaps, including the limited understanding of how process-induced defects
and geometric irregularities affect dynamic performance, and the need for standardized testing
protocols. This review emphasizes the growing importance of understanding dynamic mechanical
properties and aims to guide future research efforts toward advancing the design and application
of AM lattice structures in dynamic environments.
