Enhanced material strength

Definition

Enhanced material strength refers to the improvement in the mechanical properties of materials, such as tensile strength and durability, achieved through advanced techniques like nanotechnology. This concept is particularly relevant in additive manufacturing, where materials can be engineered at the nanoscale to create stronger, lighter, and more resilient structures that can withstand greater loads and stresses. By incorporating nanoparticles or utilizing nanostructured materials, manufacturers can achieve significant improvements in performance compared to traditional materials.
