Despite its revolutionary potential, 3D printing metals faces several challenges. High initial equipment and material costs can be prohibitive for smaller companies. Maintaining consistent quality across complex parts requires sophisticated process control and monitoring.

Powder handling and recycling present safety and contamination concerns. Additionally, post-processing steps such as heat treatment, machining, and surface finishing add time and cost.

To address these issues, manufacturers are developing more affordable and user-friendly printers. Advances in in-situ monitoring and closed-loop feedback improve reliability and repeatability. Research into new alloys tailored for additive processes enhances mechanical properties and reduces defects.

Collaboration between industry, academia, and regulatory bodies is key to developing standards and certifications, accelerating broader adoption.
