Central to the M 290's new monitoring abilities are a suite of 4 tools:
EOSTATE Base: This component monitors parameters within the M 290's build chamber including the build laser's power, position of the Z-axis, the build chamber's temperature, pressure and humidity – all factors that affect part quality.
EOSTATE PowderBed: Composed of a simple camera, the PowderBed monitor keeps watch over the M 290's powder deposition by taking still photos along each deposition pass.
EOSTATE LaserMonitoring: As suggested by its name the LaserMonitoring system ensures that the M 290's 400-watt laser maintains consistent power and radiation throughout the entire build process. This monitor ensures that each layer of a part is consistent with its surrounding layers and will have the same performance properties.
EOS ParameterEditor: The final piece of the M 290's improved systems is its ParameterEditor. With this tool users can create their own parameter sets to work with exotic alloys and custom component applications. Currently, the ParameterEditor lets users customize build laser power, exposure speed and build strategy. In the near future further options will be available including variable layer thickness, inert gas mix and build platform temperature.
In addition to the M 290's new monitoring equipment the metal sintering systems inherits much of its abilities from its predecessor, the M 280. Using a 400-Watt laser, the M 290 can process a variety of material ranging from steels to super alloys in its inert nitrogen or argon atmosphere.
The M 290 is also equipped with an optimized air circulation filter that has a self-cleaning function. Through the use of this new tool the 290 can sustain its atmospheric gas life for longer, resulting in fewer gas and filter replacements and lower operating costs.
