Advantages of FastForm FF-M420 500W×4

• Four lasers for productive SLM printing. The system with four fiber lasers, each with a power of 500 W, allows for the distribution of metal part formation between multiple scanning zones and reduces build time under appropriate conditions.
• Large working area for serial production. The build space of 420 × 380 × 400 mm is suitable for producing large metal components and group placement of parts within one production cycle.
• Precision in forming metal parts. For products up to 100 mm in size, the claimed accuracy is ±0.1 mm, and for larger parts — ±0.1% of the corresponding size. This allows the equipment to be used for manufacturing functional components and industrial equipment.
• Automated bidirectional powder application. The top-feed system with adjustable application speed of 10–500 mm/s reduces the number of idle movements between layers. Powder feed control and scraper load help prevent failures.
• Coordinated operation of four lasers. The technology of dynamic seamless connection of scanning zones coordinates the formation of adjacent areas of the part by different laser channels within one working area.
• Long-lasting filtration system. A permanent filter with a resource of at least 30,000 hours reduces the need for regular replacement of filter elements. The filtration efficiency of particles sized 0.5 μm is 99.9%.
• Automated production process control. The system monitors the parameters of the working chamber, oxygen concentration, temperature, and printing progress. The possibility of resuming the build after power interruptions is provided.
• FastLayer and FastFab software. FastLayer supports model preparation, support creation, slicing, and print parameter settings. FastFab provides equipment management and build process control.

Four-Laser System for Industrial 3D Metal Printing

FastForm FF-M420 500W×4 is equipped with four fiber lasers, each with a power of 500 W, which provide layer-by-layer melting of metal powder according to the digital model. The multi-laser configuration allows for the distribution of the build process between multiple laser channels, which is especially important when producing large parts and serial production of metal components.The technology of dynamic seamless connection of scanning zones ensures coordinated operation of four lasers. The system coordinates the formation of adjacent areas of the part by different laser channels, maintaining process consistency within the working area. The laser system operates with a wavelength of 1080 ± 10 nm. The laser beam diameter is adjustable in the range of 50–300 μm, allowing adaptation of melting parameters to the product geometry and metal powder characteristics.The maximum scanning speed is 10 m/s. For laser beam positioning, a high-precision digital scanning system with an encoder is used. The repeatability of scanning and positioning accuracy is stated at ≤2 μrad.

Precision of Formation and SLM Printing Parameters

FastForm FF-M420 500W×4 provides a formation accuracy of ±0.1 mm for parts up to 100 mm in size. For larger products, the claimed accuracy is ±0.1% of the corresponding size. These indicators characterize the equipment's capabilities, while the actual accuracy of finished parts depends on the material, geometry, model orientation, and print parameters. The thickness of the powder layer is adjustable in the range of 20–150 μm, allowing for the selection of build parameters according to the properties of the metal powder and production requirements.For titanium and aluminum alloys, the manufacturer provides examples of printing with a layer of 60 μm, and for tool and stainless steel 100 μm. Such modes can be used to increase productivity, provided the appropriate technological parameters are applied. The platform movement system is equipped with a servo drive with a closed-loop control. The minimum step of Z-axis movement is 1 μm, and the maximum platform heating temperature reaches 200 °C.

Automated Powder Feeding and Bidirectional Application

The top-feed system for metal powder ensures controlled material delivery to the working area. FastForm FF-M420 is equipped with an automated powder dosing mechanism and bidirectional application, allowing for the formation of a new layer during scraper movement in both directions. The application speed is adjustable in the range of 10–500 mm/s, and the powder layer thickness from 20 to 150 μm. The design allows for the use of a flexible or rigid scraper according to equipment settings.Automated powder feed control helps prevent process disruptions. The system monitors material availability and feed mechanism condition. In case of powder shortage or malfunction, operator warning and equipment shutdown are provided.Additional scraper load control allows for detecting critical contact with obstacles. In such cases, the system stops powder application, reducing the risk of damage to the mechanism and printed parts. The powder reservoir volume is at least 40 l. The design provides for the possibility of expanding the system with automated material feeding and circulation.

Protective Atmosphere, Oxygen Control, and Filtration

FastForm FF-M420 500W×4 supports the use of nitrogen or argon to create a protective environment during laser melting of metal powders. The controlled atmosphere limits the interaction of heated metal with oxygen, and the choice of gas depends on the alloy used and the technological process parameters. The circulation system ensures gas movement through the working chamber and filter elements. Multi-stage filtration removes particles formed during printing, maintaining the necessary conditions in the build zone.A permanent filter with a resource of at least 30,000 hours is designed for long-term equipment operation. The filtration efficiency of particles sized 0.5 μm is 99.9%. The built-in oxygen control system continuously monitors the state of the protective atmosphere and gas pressure in the working chamber. In case of deviation of controlled parameters from permissible values, a warning is activated.An additional system for monitoring oxygen concentration in the room provides for emergency equipment shutdown under hazardous conditions. The working chamber is also equipped with protective door locking, preventing accidental opening during laser operation.

Software for SLM Printing Preparation and Management

FastLayer and FastFab software provide model preparation, SLM printing parameter settings, and production process control.FastLayer supports model editing, support creation, slicing, and scanning trajectory settings. The program allows for adjusting laser power, scanning speed, and layer thickness according to product requirements.FastFab provides 3D printer management and build process monitoring, including temperature, oxygen concentration, and the number of formed layers. The system supports automatic and manual operation modes, as well as print recovery after power interruptions, reducing the risk of losing unfinished parts.
