Lattices – Why they enhance internal geometries

3D metal printing allows users to create very intricate forms easily. By tinkering with the internal geometries of printed parts they can achieve impressive mechanical properties.

One of the best ways to achieve good strength-to-weight ratios, desirable shock and sound absorption and larger surface areas is to print objects with lattice structures.

Why Lattices?

What makes lattices unique is how they layout materials into design elements to form an ideal structure that comprises of micro-architectures with a network of nodes and beams or struts. This format dramatically reduces weight while retaining structural integrity and giving a larger degree of control over certain characteristics.

These interlinking portions can enhance various areas of performance and use up less material without weakening the object or compromising its integrity.

They are common in engineering items like heat exchangers or batteries, where transmission of energy needs to be optimal. The structure allows for covering a large surface area with minimal interfering parts, so it’s also great for objects that need to be see-through or semi-permeable.
