Leveraging green light laser technology, our 3D printing process revolutionizes the manufacturing of complex metal components, particularly for advanced cooling applications. With a wavelength half that of infrared and four times the energy, green light enables up to 10x higher absorption rates in copper-based materials and 2x in aluminum, significantly improving forming efficiency while protecting optical components from damage. This technology excels with reflective and difficult-to-melt materials such as copper, gold, platinum, tantalum, and tungsten, achieving higher energy densities that facilitate melting and bonding of these challenging metals. For titanium alloys specifically, green light boosts printing efficiency by approximately 40% compared to traditional infrared methods.


The process delivers exceptional finishing details with a theoretical minimum feature size of 0.06-0.1mm, enabling the precise fabrication of intricate internal structures like lattice microchannels and turbulence-inducing geometries within cooling plates. These complex, customized designs optimize heat exchange between the coolant and the component, far exceeding the capabilities of simple fin structures. Additionally, the technology reduces airflow impact during printing, lowering requirements for smoke and dust circulation systems, and streamlines process development for common materials, accelerating manufacturing process optimization. This combination of material versatility, enhanced efficiency, and geometric freedom makes our green light 3D printing ideal for next-generation thermal management solutions across industries.
