Application of Spectroscopy in Additive Manufacturing

Area of Science:

• Materials Science
• Manufacturing Engineering
• Analytical Chemistry

Background:

• Additive Manufacturing (AM) is a transformative production technology enabling rapid prototyping and customization.
• Current AM processes are limited by raw material variability, processing defects, and inadequate final product assessment.
• These limitations hinder the widespread adoption and reliability of additively manufactured components.

Purpose of the Study:

• To review the limitations inherent in current additive manufacturing processes.
• To explore the prospective role of spectroscopic techniques in overcoming these AM challenges.
• To provide an overview of AM principles and the application of spectroscopy in assessing manufactured parts.

Main Methods:

• Literature review of additive manufacturing techniques.
• Analysis of spectroscopic principles relevant to materials characterization.
• Examination of case studies and applications of spectroscopy in AM.

Main Results:

• Identified key limitations in AM, including material selection, defect formation, and quality control.
• Highlighted the potential of various spectroscopic methods for in-situ and ex-situ monitoring.
• Demonstrated spectroscopy's capability for real-time process control and final product validation in AM.

Conclusions:

• Spectroscopic techniques are vital for addressing critical challenges in additive manufacturing.
• Implementing spectroscopy enables improved quality control, defect detection, and process optimization in AM.
• Spectroscopy offers a pathway to enhance the reliability and expand the applications of additively manufactured parts.
