Variables
Strengths & Limitations
Strengths
- +Provides a comprehensive overview of a nascent but promising AM technology.
- +Identifies key challenges and offers recommendations for future research.
Limitations
The review focuses on extrusion-based methods, which may not be suitable for all multi-material applications requiring extremely high resolution or specific material combinations not compatible with extrusion.
Reliability & validity
As a review paper, its reliability and validity depend on the comprehensiveness and quality of the sources it synthesizes. The findings are generally accepted within the field of additive manufacturing.
Think critically
How might the lower part detail of extrusion-based AM impact the functional performance of structural components compared to those produced by PBF or DED?
Design Principles
"Prioritize cost-effective additive manufacturing techniques for multi-material structural applications when high precision is not the primary driver."
This technology opens up new possibilities for producing complex, gradient, and bio-inspired multi-material parts that were previously economically unfeasible. Designers and engineers can now consider novel material combinations for structural applications where cost was a significant barrier.
What This Means for Your Design
3D printing that uses a paste-like material (like toothpaste from a tube) can be cheaper for making metal parts with different materials combined, especially if you don't need super fine details or are only making a few parts.
