Strengths & Limitations

Strengths

  • +Provides a broad overview of AM for non-metals, emphasizing sustainability.
  • +Highlights practical applications and emerging research in eco-friendly materials.

Limitations

The initial cost of some advanced additive manufacturing equipment can be high, and the range of available sustainable materials may still be limited compared to traditional methods.

Reliability & validity

The findings are based on a literature review, so reliability and validity depend on the quality and comprehensiveness of the reviewed studies. The inherent nature of AM processes suggests a generally high validity for the waste reduction claim.

Think critically

While AM significantly reduces waste, consider the energy consumption and material lifecycle of the AM process itself, as well as the end-of-life options for the printed products.
