Why is it important to understand material properties in additive manufacturing?

Understanding material properties in additive manufacturing is crucial because it directly impacts the performance, durability, and suitability of 3D printed parts for specific applications. Each material has unique characteristics such as strength, flexibility, temperature resistance, and chemical compatibility. By selecting the right material based on its properties, designers and engineers can ensure that the final product meets the required specifications and functional demands of its intended use.

For example, in applications where high strength is paramount, such as aerospace components, materials like titanium or specific high-performance polymers may be required. Conversely, for prototypes or aesthetic models, materials with good detail resolution and surface finish might be more suitable, even if they are not as strong.

This understanding leads to more efficient design processes and reduces the likelihood of failures or performance issues in the final product. In contrast, while assembly ease, aesthetic appeal, and maintenance considerations are important factors in the overall additive manufacturing process, they do not directly address the critical need for proper material selection based on inherent material properties.
