Green laser enables high performance 3D printed induction coil: Pure copper, copper alloy all at your choice

Introduction

By implementing green laser PBF printing technology, both pure copper and copper alloy can be used for induction coil 3D printing to replace traditional machining and brazing. The coils, manufactured directly from digital models in complex shape, reduce production lead time by two-thirds while ensuring dimensional accuracy and material integrity. The laser sintered copper matrix enhances structural rigidity, leading to a longer service life and superior resistance to thermal fatigue compared to brazed counterparts.

Technical Requirements for Induction Coils

Induction coils are the heart of induction heating systems, ensuring efficient, precise, and repeatable processes across industries. A high-quality coil must meet four key requirements.

With green laser, pure copper is no longer a challenge for additive manufacturing

The demanding requirements of induction coils make Laser Powder Bed Fusion the ideal manufacturing method. However, conventional infrared lasers struggle with copper's high reflectivity. As a result, traditional approaches often rely on alloys with low copper content with compromised conductivity.

Addireen's PBF printers, equipped with advanced short-wavelength green lasers, overcome this challenge and enable the reliable 3D printing of pure copper and high-copper alloys. This positions us as a global leader in copper additive manufacturing and a specialist in 3D-printed induction coils.

Benefits

1. One-piece integrated manufacturing with longer lifetime 

By using a 3D printer to produce the coil in one piece, no brazing required which eliminates joints and welds, reducing weak points and leads to stabilization and improvement of coil life. 

• Smooth inner walls for efficient fluid flow 

  
  

  

• One-piece printed with no weld joints

  
  

  

• Green laser additively manufactured for long service life 

  
  

  

2. Complex geometry with controlled reproducibility

3D printing facilitates the realization of complex designs that were formerly impossible, thereby enhancing the possibility of unrestricted designing. The intricate waterway can be structured in various configurations. No more manual work to ensure production of identical inductors, to reduce system set-up or adjustments. 

3. Flexible manufacturing to ensure fast delivery

Flexible and consistent low-cost for both small-batch and volume production. 3D printing significantly shortens the delivery time. Ordinarily, the production time is approximately two months. With 3D printing technology, this time can be cut down to 2 weeks. With dozens of equipment standby, Addireen service factory can quickly adjust to mass production.
