  • SLM 500 - Bauraum

The Selective Laser Melting Machine SLM 500 provides a build envelope of 500 x 280 x 365 mm³ and the patented multi-beam technology. In the high-performance SLM 500 Machine, four fiber lasers (4x 400 W or 4x 700 W) are in action simultaneously, increasing the build-up rate by up to 90% compared with the twin configuration (2x 400 W or 2x 700 W).

The universally usable SLM 500 Selective Laser Melting Machine is a high-performance winner, thanks to its large build envelope and quad laser technology. An extremely comprehensive basic confi guration and the large choice of options enable applicationoriented machine confi guration. The machine’s patented multi-beam technology is a central component of the SLM 500. With the twin (2x 400 W or 2x 700 W) and optional quad (4x 400 W or 4x 700 W) optical confi guration, this machine is specifi cally designed for use in the production environment.

The machine has fully automated powder management located between the SLM Machine and the Powder Supply Unit (PSV). The metal powder is continually sieved and fed to the construction process. This eliminates time-consuming manual fi lling of the machine. Tasks like cleaning the cylinder and removal of the build parts are efficiently performed in the separate Part Removal Station (PRS). The subsequent construction process can be started in parallel with a second build cylinder.

The build parts are prepared with the software Magics RP and the module support generator SG+, as well as the SLM Build Processor. The data formats used in the industrial environment can be loaded and processed. As well as this, a comprehensive monitoring and quality assurance system enables a high degree of process control in the machine.

Powder Supply Unit PSV

To ensure a reliable powder supply to the SLM 500 throughout the entire production process, a modular powder supply unit (PSV) is connected to the machine.

The PSV uses a 90-liter powder tank which is sufficient for any production process. Manual filling of powder via individual powder bottles is not necessary. An ultrasonic sieve, which is integrated in the PSV, sieves the available powder just before it is fed into the process so that no oversized particles or foreign objects can find their way into the SLM process. The transport of powder between the PSV, the SLM machine and the Part Removal Station (PRS) is fully automatic and carried out via vacuum technology. The PSV uses three independent conveying routes. In addition to supplying the freshly sieved metal powder to the SLM machine, a second conveying route returns the excess metal powder from the overflows back to the PSV. The third conveying route uses a manual suction device to remove the excess metal powder from the PRS which is then conveyed directly back to the PSV. During this step, a new production process can already be started using the SLM machine whereat the powder supply to the SLM machine is then prioritized. Fresh powder is either supplied through the direct connection of powder containers to the powder tank from the PSV or through the emptying of the powder container directly in the PRS via a suction device.
Powder transport, powder sieving and the storage of the powder take place in a closed system with inert gas atmosphere. Contactless powder handling ensures maximum safety at work.

Part Removal Station PRS

The Part Removal Station PRS is a basic feature of the SLM 500. This useful component of the machine is optimally suited for batch production, and serves for removing the excess powder from the build cylinder and the build parts.

Based on the unloading position, the construction cylinder is removed with the handling device, which is also a basic feature, from the SLM 500 and transferred to the Part Removal Station PRS.

With the use of the PRS, the created build parts can be ergonomically released from excess powder without any skin contact. The build cylinder is extremely comfortable to reach, thanks to the integrated, gas-tight gloves, and the operator is not exposed to the metal powder. All SLM build parts are manufactured on a substrate plate located on the machine’s platform. This is raised in the station, and the excess powder collects easily in the powder storage containers on the sides. Finally, the powder is automatically transported from the storage containers to the Powder Supply Unit PSV where it is prepared for use again.
