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

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

FastForm AiForm-G2 500W×2 Green Laser is an industrial SLM 3D printer with two green lasers, each with a power of 500 W, for printing with pure copper, featuring a build volume of 300 × 300 × 400 mm. The model is designed for thermal management, heat dissipation, and cooling tasks, particularly for manufacturing large cold plates, heat exchangers, and serial copper components. The simultaneous operation of two green lasers increases the productivity of part manufacturing. Green Laser technology is applied for working with pure copper and forming microchannels, TPMS structures, and complex flow channels in parts for liquid cooling and heat exchange.

Key advantages of the FastForm AiForm-G2

• Two 500 W green lasers. The lasers simultaneously melt metal powder in different zones of the platform, shortening the production cycle time. The productivity of each laser is 10–25 cm³/h. The actual result depends on the model geometry, printing parameters, and scanning strategy, so an accurate estimation should be based on specific parts.
• Density up to 99.9%. The green lasers ensure a high density of copper parts with minimal porosity, which reduces the risk of leakage and loss of thermal conductivity in cooling systems.
• Large components in a single piece. The build volume is sufficient for large cold plates, manifolds, and heat exchangers with extensive channels. There is no need to divide the structure into parts and join them later.
• Manufacturing precision. The tolerance is ±0.1 mm for dimensions up to 100 mm and ±0.1% of the dimension for larger parts. Scanning repeatability is no worse than 2 µrad. This is important for microchannels: even a small deviation alters the hydraulic resistance and heat dissipation efficiency.
• Cooling channels inside the part. SLM allows building microchannels, branched mains, and TPMS structures directly inside a monolithic copper workpiece. Such shapes cannot usually be achieved by machining.
• Stable thermal regime. The platform heats up to 200 °C, and the temperature is maintained within ±0.1 °C. Uniform heating reduces thermal gradients during melting and helps maintain control over the process.

Features of operating two green lasers with pure copper

Pure copper has the highest thermal conductivity among common structural metals, making it used for heat dissipation. However, in the near-infrared range, it highly reflects radiation. Classic SLM systems with infrared lasers lose a significant portion of energy and do not always provide stable melting. The FastForm AiForm-G2 is equipped with two green lasers, each with a power of 500 W. Copper absorbs their radiation much better. The powder melts more uniformly, and the parts turn out dense. This opens the way to products with internal channels, compact heat exchange elements, and branched flows. The simultaneous operation of two lasers increases the productivity of additive manufacturing, especially during serial printing.

Large volume for industrial tasks

The 300 × 300 × 400 mm space allows placing several parts in a single production cycle. This is particularly useful for cold plates and heat exchangers: they have long channels, distribution manifolds, and several functional zones.

Thanks to SLM, all these elements are combined into one monolithic structure. There are fewer parts and mechanical joints, and therefore, fewer places where the coolant can leak. For long cycles, the following are provided:

• a 40 L powder supply system;
• an additional 40 L external hopper (optional);
• a 60 L overflow powder container.

Such a powder reserve allows running long production cycles with fewer stops for refilling.

Scanning precision and temperature control

The printer is equipped with a high-precision laser scanning and platform positioning system. Scanning repeatability is ≤2 µrad, Z-axis positioning accuracy is <±0.03 mm. The layer thickness can be varied between 20–80 µm: thinner layers are suitable for fine features and better surface quality, while thicker ones reduce build time. Preheating up to 200 °C with an accuracy of ±0.1 °C maintains process stability during the printing of copper components. The maximum laser scanning speed is 10 m/s.

Microchannels and TPMS structures for heat exchange

The main strength of the FastForm AiForm-G2 is parts with complex internal geometries that are difficult or impossible to manufacture using traditional machining. Inside copper components, it is possible to form:

• Cooling microchannels. Compact flow structures that direct the coolant close to heated surfaces.
• Multilevel and branched channels. Internal fluid distribution systems for cooling multiple functional zones.
• Variable cross-section channels. Geometries that allow controlling flow characteristics according to the design intent.
• TPMS structures. Periodic minimal surfaces with a large contact area that enhance heat exchange.
• Thin-walled ribbed structures. Elements that increase the heat transfer area in compact heat exchangers.

The high thermal conductivity of copper combined with design freedom enables the creation of compact heat exchange assemblies, where several functions are integrated into a single part.

Where the FastForm AiForm-G2 is used

The printer is created for the industrial production of functional copper components that require high thermal conductivity, complex internal geometry, and the combination of multiple functions into a single product. Main areas:

• AI processor cooling. Cold plates with microchannels for heat dissipation from high-performance computing components.
• Servers and data centres. Copper elements for liquid cooling, distribution manifolds, and heat exchangers.
• Industrial heat exchangers. Compact structures with TPMS structures, thin fins, and optimised channels for the coolant.
• Power electronics and energy. Cooling components for power converters, storage systems, and charging equipment.
• Serial production of copper parts. Functional products with complex geometry and a minimum of assembly operations.
