PANDA can be configured with our optional AMSENSE® multi-sensor data collection and analysis platform, providing access to raw and processed data each layer through our proprietary software that runs on included Windows 10 computer. AMSENSE features several standard sensors as individual options, along with plugin interface allowing integration of future modules and user-developed/third-party code. In addition to optional AMSENSE modules, all PANDA systems include a Windows-based build camera for real-time viewing and recording of photos and videos as a standard feature.

Available AMSENSE modules:

  • Recoat imaging sensor – automatically records high-resolution images before and after each recoat
  • Thermal tomography sensor – high-resolution NIR imagery compiled into emissions maps for each layer
  • Spatter tracking sensor – detects, identifies, and tracks spatter events, and provides key spatter statistics
  • Longwave Infrared – LWIR video provides video of solid-state heat flow and background temperatures
  • Custom sensors/analytics – customer-specific or emerging capabilities may be integrated, as warranted

Note that AMSENSE can also be integrated on other industrial LPBF systems, beyond Open Additive systems.

More information:  See handout

Each PANDA includes:

  • Inert gas chamber – provides positive pressure environment (non-vacuum) for shielding gas (e.g., N2 or Ar)
  • Cross-bed flow – removes soot and debris to minimize defects; users may modify outlet and intake for application needs
  • Optics gas flow – provides flow across laser optics to prevent debris accumulation during the build
  • Integrated filtration – gas recirculation is provided by industrial two-stage filter for removal of debris particles
  • Safe passivation – filters can be rolled to passivation site without exposure to Oxygen
  • Sensors and control – oxygen levels are controlled by sensors and software with automated shutoff/alarm capabilities

Open Additive will provide starting parameters and available technical data at no extra charge for these common LPBF materials:

  • Stainless steel 316L and 17-4 PH
  • Aluminum alloy AlSi10Mg
  • Nickel-chromium alloy In718
  • Titanium alloy Ti-6Al-4V

Users always have the capability to see and modify these parameters, or create their own. The system places no restrictions on materials feedstock, though we can provide, if convenient.  We can work with prospective customers or system users to develop parameters and/or perform demonstration builds using most materials.
