3D printer SLM FastForm AiForm-G2 500Wx2 Green Laser

Industrial SLM 3D Printer FastForm AiForm-G2 for Printing Pure Copper

FastForm AiForm-G2 500W×2 Green Laser is an industrial SLM 3D printer with two green lasers, each with a power of 500 W, designed for the production of high-precision parts from pure copper. The equipment is focused on the production of components for liquid cooling systems, cold plates, heat exchangers, and other products with complex internal geometry. The build area of 300 × 300 × 400 mm allows for the production of large copper components and production batches of parts.

Advantages of FastForm AiForm-G2

• Productive dual-laser 3D printing. Two green lasers, each with a power of 500 W, enable parallel processing of metal powder. The manufacturer claims a productivity of 10–25 cm³/hour per laser.
• High density of copper parts. The Green Laser technology ensures the formation of components from pure copper with a density of up to 99.9%, which is important for the production of functional heat exchange structures.
• Manufacturing of large components. The build area of 300 × 300 × 400 mm allows for printing large cold plates, heat exchangers, and other parts with complex internal geometry.
• High manufacturing precision. The precision is ±0.1 mm for sizes up to 100 mm and ±0.1% of the size for larger parts. The scanning repeatability does not exceed 2 μrad.
• Integrated cooling channels. SLM technology allows for the creation of microchannels, branched flow systems, and TPMS structures directly inside monolithic copper components.
• Stable forming conditions. Heating the work platform to 200 °C with a temperature stability of ±0.1 °C contributes to a controlled process of laser melting of pure copper.

Green Laser Technology for SLM 3D Printing of Pure Copper

Pure copper is characterized by high thermal conductivity and is widely used in the production of cooling and heat dissipation system components. At the same time, its high reflectivity in the near-infrared range complicates laser processing with traditional SLM systems.

FastForm AiForm-G2 500W×2 Green Laser uses green laser radiation, which is more efficiently absorbed by copper compared to infrared. This contributes to stable melting of the metal powder and the production of dense functional components. The technology allows for obtaining copper parts with a density of up to 99.9% and implementing designs with internal cooling channels, compact heat exchange elements, and branched flow structures.

The dual-laser configuration creates opportunities for increasing the productivity of additive manufacturing. The formation speed is 10–25 cm³/hour per laser, and the actual productivity depends on the geometry of the parts, printing parameters, and scanning strategy.

Large Build Area for Industrial Production

FastForm AiForm-G2 has a build area of 300 × 300 × 400 mm, allowing for the production of large copper components and the placement of multiple parts within a single production cycle. This working volume is especially important for the production of cold plates and heat exchangers, whose design involves long channels, distribution manifolds, and multiple functional zones.

SLM technology allows for combining these elements into a monolithic structure, reducing the number of separate parts and mechanical connections. This simplifies the implementation of complex cooling systems and reduces the number of potential leak points for the working fluid. For long production cycles, a powder supply system with a volume of 40 l, an additional external hopper of 40 l (optional), and a container for excess powder with a volume of 60 l are provided.

Printing Precision and Temperature Control

FastForm AiForm-G2 is equipped with a high-precision laser scanning and work platform positioning system. The scanning repeatability is ≤2 μrad, and the Z-axis positioning accuracy is <±0.03 mm. The layer thickness is adjustable in the range of 20–80 μm, allowing for the selection of forming parameters according to the geometry of the parts and production requirements.

The work platform supports preheating up to 200 °C with a temperature stability of ±0.1 °C. Temperature control contributes to the stability of the copper component manufacturing process. The maximum laser scanning speed is 10 m/s.

Microchannels and TPMS Structures for Efficient Heat Exchange

One of the key capabilities of FastForm AiForm-G2 is the production of parts with complex internal geometry, which is difficult to achieve with traditional mechanical processing methods. SLM 3D printing allows for the formation of the following inside copper components:

• Cooling microchannels. Compact flow structures that ensure the circulation of the coolant near heated surfaces.
• Multilevel and branched channels. Internal fluid distribution systems for cooling multiple functional zones.
• Channels with variable cross-sections. Geometries that allow for controlling flow characteristics according to the cooling system design.
• TPMS structures. Periodic minimal surfaces with a developed contact area that can be used to intensify heat exchange.
• Thin-walled ribbed structures. Elements designed to increase the heat transfer area in compact heat exchangers.

The combination of high thermal conductivity of pure copper and the freedom of geometric design allows for the creation of compact heat exchange components with integrated functional elements.

Applications of FastForm AiForm-G2 Green Laser

FastForm AiForm-G2 is intended for the industrial production of functional components from pure copper, particularly parts where high thermal conductivity, complex internal geometry, and the integration of multiple functions in one product are important. Main applications:

• AI processor cooling systems. Manufacturing cold plates with microchannels for heat dissipation from high-performance computing components.
• Server and data center cooling. Production of copper liquid cooling components, distribution manifolds, and heat exchange elements.
• Industrial heat exchangers. Creating compact designs with TPMS structures, thin ribs, and optimized coolant circulation channels.
• Power electronics and energy systems. Manufacturing cooling components for energy converters, storage devices, and charging equipment.
• Serial production of copper parts. Manufacturing functional components with complex geometry and minimal assembly operations.
