Material Research with InssTek

We're pleased to share a significant study from Materials Research Letters (2023) on the "Local composition detouring for defect-free compositionally graded materials in additive manufacturing."

Highlights from the Study:
1. Innovative Method: Introduction of a new method for manufacturing defect-free compositionally graded materials (CGMs), focusing on local composition adjustments.
2. Efficiency Gains: This method not only saves time and materials but also eliminates the need for pre-powder mixing, making it highly efficient.
3. Defect-Free Production: By tailoring compositions in specific regions, defect-free parts with functionally graded materials (FGM) can be achieved.
4. Experimental Success: Utilization of SS316L and IN718 powders in a Directed Energy Deposition (DED) process, demonstrating smooth transitions and crack-free regions.

Technology in Action:
• InssTek’s Multi-Powder Feeding System: Enabled simultaneous in-situ alloying, crucial for the LCD method.
• Schematic Overview: The DED process involved a gradual increase in IN718 volume fraction, achieving g a defect-free gradient over 54 layers.

This innovative approach marks a significant step forward in the field of additive manufacturing, opening new avenues for the creation of advanced materials with precise properties and minimal defects.
