EOS M 290 DMLS system
RAPID 2014 is fast proving to be the most popular US event for big machine releases, with EOS announcing the successor to its EOSINT M 280 system at the Detroit-based expo.
The e-manufacturing technology and additive manufacturing solutions provider unveiled the EOS M 290 Direct Metal Laser Sintering (DMLS) 3D printer yesterday (June 10th), displaying the new hardware on its booth (#1210).
Dr Adrian Keppler, CMO at EOS, commented: "EOS has incorporated proven elements from the M 280 system generation in the new EOS M 290, but at the same time, the EOS M 290 also allows us to set new standards in additive manufacturing while expanding our product portfolio for metal applications and extending our innovation leadership in terms of quality management and monitoring. This new system is designed to serve the requirements of our serial production customers."
EOS is showcasing this brand new M 290 system to demonstrate its ability to produce high-quality serial components, prototypes and spare parts flexibly and economically.
Keppler added: "We have also created new optimisation potential in terms of build quality for customers from the prototyping space."
The new system has a 250 mm x 250 mm x 325 mm build volume and, despite all the innovations that have been incorporated in the EOS M 290, the new M 290's central processing elements have been retained: process chamber, gas stream, process parameters, etc. This ensures constant process behaviour and in turn consistent component quality beyond the EOSINT M 280 and EOS M 290. The system is now available to purchase.
Andrew Snow, Senior Vice-President, EOS of North America, said: "The M 290 sets a new standard for the North American market. We are listening to our customers and the demand is part-cost reduction. The new system provides that by offering a module design with standardised electrical controls to improve the overall serviceability. This system also reduces the recurring cost of operation by maintaining a reduced and improved gas flow in the processing chamber as well as an innovative self-cleaning, long-life, recirculating filter system. All of these elements serve our current and future customers' requests for a reduction in operation and cost-per-part expense."
The official word from EOS
Extensive quality management, expanded monitoring functions, EOSTATE
The new EOS M 290 offers extensive monitoring functions both for the system itself and for monitoring the build process. This adds even more extensive quality assurance to the field of AM. In particular, it makes the system attractive for industrial applications in the aerospace industry as well for medical applications. With the aid of EOSTATE PowderBed, a camera built into the process chamber monitors the powder bed, following powder deposition and exposure, by means of still images. EOSTATE Base ensures the consistent monitoring of a range of parameters, including the position of the Z axis or scanner, laser power, air humidity, temperature and pressure. Finally, EOSTATE LaserMonitoring measures the laser power throughout the entire build period.
Flexible components and extensive accessories
The system is equipped with a 400 Watt laser, which is characterized by its high radiation quality and stability of performance. The EOS M 290 can be operated under an inert (nitrogen) atmosphere or under argon, which permits processing of a great breadth of materials. These include light alloys, stainless and tool-grade steels, and superalloys. The EOS parameter sets ensure that parts can be manufactured with standardized property profiles, resulting in a broad spectrum of applications. As with the previous model, EOS also supplies its EOS M 290 customers with the EOS ParameterEditor, to allow them to modify a range of exposure parameters for themselves. The tool enables customers to develop their own parameters for specific applications on the basis of the EOS parameter sets. These include laser power and exposure speed or strategy. A new version of the ParameterEditor is currently under development, which will also allow modification of layer thickness, inert gas stream, build platform temperature, and skip layers.
High level of user friendliness, optimized process gas management, intuitive software
The EOS M 290 is even more user friendly thanks to the new EOSYSTEM machine software, which allows intuitive and task-oriented operation of the system via a graphic user interface (GUI), which was developed especially for production environments. In addition, an operator assistant is included which guides the user through the program. The new EOSPRINT Desktop Software allows jobs to be prepared and computed directly at the workplace, separately from the build process. The job file can then be transferred through the network to the system, which can then concentrate fully on building the part. Thanks to the availability of offline job preparation, complex parts with large job files can be processed quickly. This in turn improves the flexibility of the application development process.
Process gas management has also been optimized. The EOS M 290 is fitted with an air circulation filter which itself is equipped with an automatic self-cleaning function. This considerably increases the filter’s operating life, with the result that it requires less frequent replacement. It also reduces filter costs.
The solution portfolio for the EOS M 290 also includes data preparation software, component handling devices, and extensive services.
