SLM Solutions Unveils SLM 500 HL Selective Laser Melting Machine

At EuroMold this year SLM Solutions will present the SLM 500 HL selective laser melting machine, in Hall 11.0, booth C80. On Nov 27th the new system will be unveiled to interested trade fair visitors. The laser beam melting system SLM 500 HL is both the largest and most productive system for powder-bed based laser beam melting.

The SLM 500 HL provides a build chamber of 500 x 280 x 325 cm³ and a unique double beam technology. Each of the two fibre lasers (400 +1000W) operate on the powder bed by a 3D scanning unit. Two of these units are working at the same time what makes a total of 4 lasers in operation. Included in the SLM® 500 HL is the shell-core-imaging process with two different laser beam profiles. These profiles may be used independently, but also parallel and simultaneously in the process. This will significantly increase productivity.

This method takes into account not only 2 lasers operating simultaneously and parallel ("Dual spot scanning"), but at the same time the lasers are melting several layers of powder in one melting process with a 1000W-Laser.  That is the reason why the melting process has a 10 times higher build rate compared to former additive metal systems.

To manage the weight of higher metal volume, a new changeable build chamber has been developed. The transport of metal powder is done by a continuous conveying system due to the increased volumes and weights. This automates the management of powder and eliminates the manual handling of loads with bottles and containers. The time consuming manual filling the system no longer applies.

The system offers Magic AutoFab to process CAD/STL data files as a standard feature which is also used for slicing and support generation. In addition the software architecture includes modules for monitoring, auditing and quality assessment to exercise optimal quality control in production.

These options contribute to an uninterrupted and error-free basis melting process. They not only present high quality assurance requirements in medical technology, aviation and aerospace, but also significantly increase the level of process reliability and reproducibility.
