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

3D Printer SLM FastForm AiForm-G2 Green Laser is an industrial metal 3D printing system with 500W green lasers, designed for producing high-precision functional parts from pure copper. The equipment is intended for manufacturing liquid cooling components, cold plates, heat exchangers, and other products with complex internal geometry. Build area of 300 × 300 × 400 mm allows for the production of large copper components and simultaneous placement of multiple parts on the work platform.

Advantages of FastForm AiForm-G2 Green Laser

• Efficient SLM 3D printing with pure copper. Green laser radiation ensures efficient energy absorption by copper powder, promoting stable material melting and forming dense metal parts.
• High density of finished products. Green Laser technology allows for copper components with a density of up to 99.9%, which is important for manufacturing functional parts of heat dissipation systems.
• Large build area. The working volume of 300 × 300 × 400 mm is suitable for printing large heat exchangers, cold plates, and production batches of parts.
• High-precision laser scanning. Scanning repeatability ≤2 μrad and Z-axis positioning accuracy <±0.03 mm ensure controlled formation of complex geometric structures.
• Integration of internal channels. SLM technology allows for the production of monolithic copper components with microchannels, distribution manifolds, thin fins, and TPMS structures.
• Platform temperature control. Preheating up to 200 °C with stability ±0.1 °C maintains controlled temperature conditions during printing.
• Metal powder management system. Built-in powder supply system with a volume of 40 liters, a 60-liter excess powder container, and the option to install an additional hopper support long production cycles.

Green Laser Technology for 3D Printing with Pure Copper

Pure copper has high thermal conductivity, making it widely used in the production of heat exchangers, cooling plates, and power electronics components. However, due to its high reflectivity in the near-infrared range, its processing with traditional laser systems requires careful selection of technological parameters.

FastForm AiForm-G2 Green Laser uses 500W green laser radiation, which is more effectively absorbed by copper compared to infrared. This improves energy transfer to the metal powder and creates conditions for stable formation of high-density parts. The technology allows for the production of components with a density of up to 99.9%, including structures with complex internal channels, thin-walled elements, and integrated heat exchange structures.

The formation productivity is 10–25 cm³/hour per laser. The actual production speed depends on the geometry of the product, layer thickness, laser processing parameters, and scanning strategy.

Large Build Area for Industrial Production

FastForm AiForm-G2 is equipped with a working chamber with a build area of 300 × 300 × 400 mm, allowing for the production of large copper components or placing multiple products within a single print cycle. This format is particularly relevant for the production of cold plates, heat exchangers, and distribution manifolds, whose design involves long coolant circulation channels and complex internal cavities.

Thanks to SLM technology, individual functional elements can be combined into a single monolithic structure. This reduces the number of mechanical connections, simplifies assembly, and reduces the number of potential coolant leakage points. To support long production processes, a powder management system is provided:

• 40 liters — volume of the built-in metal powder supply system.
• 40 liters — volume of the additional external hopper, available as an option.
• 60 liters — volume of the excess powder container.

This configuration is oriented towards industrial production of large-sized parts and performing long cycles of metal 3D printing.

High Printing Accuracy and Process Stability

FastForm AiForm-G2 combines a high-precision laser scanning system with precise positioning of the work platform. Scanning repeatability is ≤2 μrad, and Z-axis positioning accuracy is <±0.03 mm. The maximum laser scanning speed reaches 10 m/s. Dimensional accuracy of production is:

• ±0.1 mm — for sizes up to 100 mm inclusive.
• ±0.1% of size — for sizes over 100 mm.

Layer thickness is adjustable in the range of 20–80 μm, allowing for the selection of printing parameters according to the complexity of the geometry and manufacturing requirements of the parts.

The work platform supports preheating up to 200 °C with temperature stability of ±0.1 °C. Temperature control helps maintain stable conditions for laser melting of metal powder.

Manufacturing Microchannels and Complex Heat Exchange Structures

One of the main advantages of FastForm AiForm-G2 is the ability to manufacture copper parts with complex internal geometry, which is difficult or impossible to achieve with traditional mechanical processing methods. SLM 3D printing allows for the integration of various functional elements into the design:

• Cooling microchannels. Compact internal channels for circulating coolant near surfaces from which heat needs to be dissipated.
• Branched flow systems. Internal channels and manifolds for distributing coolant between multiple cooling zones.
• Channels with variable cross-section. Geometries that allow for adapting coolant flow to the structural features of the product.
• TPMS structures. Periodic minimal surfaces with a developed contact area, which can be used to enhance heat exchange efficiency.
• Thin-walled ribbed elements. Compact structures with increased heat transfer area for heat exchangers and cooling systems.

The combination of high thermal conductivity of pure copper and the capabilities of additive manufacturing allows for the creation of compact heat exchange components with integrated channels and functional elements.
