80% more productivity in 3D printing

DMG MORI Additive strengthens SLM process with automation technology

"Our aim is to achieve a high level of maturity of CNC machines with our additive manufacturing machines," explains Dr. Vino Suntharakumaran, Managing Director at DMG MORI Additive GmbH. The company is not far off reaching this aim with the LASERTEC 30 DUAL SLM, which increases productivity by 80%. Festo has been brought on board as a development partner. Thanks to its ready-to-install automation solution, the inert gas atmosphere is precisely managed.  

The LASERTEC 30 DUAL SLM from DMG MORI Additive is the flagship for additive manufacturing by selective laser melting (SLM) in a powder bed. It produces highly complex components with function integration, internal close-contoured cooling channels and reduces product development times thanks to prototypes made of series materials that are available straightaway. Two powerful 600 W lasers, each with scan fields covering the entire installation space, enable build rates of up to 90 cm³/h. 


Faster and safer powder module change

Other advantages: the dual-laser system improves productivity by 80% compared to a single-laser system. The powder module for quick material change, called rePLUG, automates powder handling. Reprocessing the powder in an inert gas atmosphere ensures greater efficiency and occupational safety thanks to the closed material circuit. With the powder module, it is possible to switch between different materials in less than two hours and without any contamination.


Another innovation is the permanent filter system, which works independently of the material and offers a new level of durability and occupational safety thanks to the automatic passivation of metal dusts. Since the installation space is actively cooled, users can remove finished components earlier and thus prepare new jobs more quickly. The result is a further increase in productivity.


Process gas fully under control

The process gas atmosphere plays a decisive role. It is important that the pressure and oxygen content remains within narrow limits to ensure high component quality. "A Festo automation solution helped us achieve a breakthrough here," says Suntharakumaran. The solution consists of a unit for filling the working chamber with inert gas. Only a safe inert gas atmosphere ensures stable processes in additive manufacturing. "The prerequisite for this is innovative products for flow and pressure control, which we get from Festo," adds 3D expert Suntharakumaran.


The ready-to-install complete solution from Festo consists of a mounting plate equipped with the valve terminal VTUG including EtherCAT bus connection, the pinch valve VZQA, the MS4 service unit and the proportional-pressure regulator VEAB. The valve terminal VTUG is suitable both in terms of pneumatics and control technology. The pinch valve VZQA precisely controls the inert gas argon and the evacuation of the gas mixture during the purging process.


Innovative automation solution

The proportional-pressure regulator VEAB is compact yet has precise and dynamic control characteristics. These valves offer high-precision flow control at up to 20 l/min. with low hysteresis, high repeat accuracy and low energy consumption. The proportional characteristics of a piezo bender with direct actuation ensure stable and reliable regulation and a stepless pressure rise. The MS4 service unit has a modular design for compressed air supply and its components can be freely combined. These include pressure regulators, on/off and soft-start valves with safety function, filters, pressure and flow sensors, dryers, sensors and lubricators. This means there is a solution for every task.


All automation products used are suitable for inert gases. "This solution keeps the pressure and oxygen content within narrow limits," adds the 3D printing expert. It also halves the cycle time by shortening the time needed to fill the workspace.


Simulation software also in demand

Festo services are not limited to supplying the automation solution. The automation manufacturer's experts were also involved in developing the machine. With appropriate software and engineering tools from Festo for simulation, it was possible to embed the automation components in the machine and the development processes at an early stage and thus become part of the solution early on.


DMG MORI, as one of the world's leading companies in machine tool manufacturing, is further expanding its technological leadership. "That is why it is important for us to join forces with innovative partners. Festo is such a partner for us, because as a manufacturer of pneumatic and electric automation technology it focuses and works on future topics, as can be seen in bionic grippers or the Festo AX digitalisation solution," explains Suntharakumaran. They are thus both looking for further solutions to automate labour-intensive activities, for example when loading and unloading the construction cylinder.
