718 Sheet: Revolutionizing Additive Manufacturing Capabilities
Enhanced Material Properties for 3D Printing
The exceptional properties of 718 sheet make it an ideal candidate for additive manufacturing processes. Its high strength-to-weight ratio, excellent resistance to oxidation and corrosion, and superior creep-rupture strength at elevated temperatures contribute to the production of robust and durable 3D-printed components. These characteristics are particularly beneficial in industries such as aerospace and energy, where parts must withstand extreme conditions.
Improved Process Efficiency and Part Quality
When used in powder form for selective laser melting (SLM) or electron beam melting (EBM) processes, 718 alloy offers excellent flowability and packing density. This results in more uniform layer deposition and better overall part quality. The material's good weldability also translates to improved interlayer bonding during the 3D printing process, leading to stronger and more reliable finished products.
Expanding Design Possibilities
The versatility of the 718 sheet in additive manufacturing opens up new design possibilities for engineers and manufacturers. Complex geometries that were previously impossible or impractical to produce using traditional manufacturing methods can now be realized through 3D printing. This enables the creation of optimized components with reduced weight, improved performance, and enhanced functionality.
