Traditional part designs rely on solid internal volumes to maintain structural integrity. But in modern applications, especially in aerospace, automotive, and medical industries, weight reduction is critical. That’s where lattice structures come in. By replacing solid cores with carefully engineered internal frameworks, parts can become up to 40% lighter while still meeting mechanical requirements.
Lattices work by distributing load paths more efficiently. Instead of a single solid mass absorbing all forces, a web-like network of struts carries the load across the structure. This not only reduces mass but also opens new doors in thermal management, as heat can flow more predictably through open channels.
These advantages extend beyond performance. Lattices reduce the amount of material used, which lowers raw material costs and shortens 3D print times. That’s a huge benefit when working with expensive alloys or large-scale production runs. Moreover, internal lattices can be customized for specific properties, such as energy absorption or directional stiffness, making them ideal for multifunctional components.
Of course, not all designs benefit equally from lattices, and simulation plays a crucial role in validating their effectiveness. But when done right, the payoff is substantial: lighter, smarter, more efficient parts that align with modern engineering demands.
