Green-Laser Copper Coil 3D Printing — ADDIREEN Delivers High Performance and Rapid Production

In industries such as induction heating and electronics manufacturing, high-frequency induction coils are critical components. Traditionally produced via machining and brazing, they suffer from long production cycles and weak joints that compromise durability and stability. With the advent of green-laser metal 3D printing, these challenges are being overcome.

One-Piece Construction — No Welding Required

ADDIREEN employs Green Laser Powder Bed Fusion (GL-PBF) technology to directly print pure copper and copper-alloy induction coils. Unlike conventional methods, the printed coils form an integrated monolithic structure—completely eliminating weld seams and joints that typically lead to fatigue cracking. This significantly enhances both lifespan and structural reliability.

· Seamless Construction: No joints or weak points.

· Smooth Inner Channels: Optimized for efficient coolant flow.

· Improved Longevity: Reduced thermal fatigue and wear.

The high reflectivity of copper once made it difficult to print using conventional infrared lasers. Hihe’s green-laser process now enables precise internal channel formation with smooth surfaces, improving heat dissipation and flow dynamics.

Complex Geometry, Infinite Design Freedom

Traditional machining is restricted by tool geometry and weld limitations, making intricate cooling-channel designs nearly impossible. 3D printing breaks these barriers, allowing the creation of complex geometries with perfect repeatability, reducing manual post-processing and ensuring high consistency across batches.

Faster Production, Quicker Delivery

Conventional coil manufacturing often requires up to two months. With ADDIREEN’s green-laser 3D printing solution, lead time is cut to as little as two weeks. Multi-printer parallel production allows the company to flexibly handle both small-batch customization and mass production.

Advantages at a Glance

· Longer Lifespan: Eliminates weld-related weak points.

· Superior Performance: High electrical and thermal conductivity.

· Design Freedom: Easily integrates complex cooling channels.

· Rapid Delivery: Lead times reduced to one-quarter of traditional methods.

· Wide Applications: Aerospace, new energy vehicles, and consumer electronics.
