05

Design Principles

"Material performance in additive manufacturing is a function of alloy composition, processing parameters, and the resulting microstructure."

The unique layer-by-layer building process of additive manufacturing (AM) imposes specific demands on material properties. By tailoring alloy compositions, designers and engineers can overcome limitations related to thermal cycling and solidification, enabling the creation of complex and high-performance parts.

06

What This Means for Your Design

To make metal parts using 3D printing (additive manufacturing), you need special metal powders. The type of metal powder (its composition) really matters because the printing process involves a lot of heating and cooling, which can change how the metal behaves. Understanding these changes helps create better metal parts.
