Linde, a global leader in industrial gases and technology, collaborates with universities and manufacturers to improve additive manufacturing processes. Linde’s new global R&D center focuses on the effect of atmospheric gases and mixtures on metal powders to optimize layering processes during 3D printing.  Linde will showcase three new ADDvance® technologies developed to improve the quality of metal additive manufacturing.  They target incoming quality of powders, 3D process quality and finish quality.

  •  The ADDvance® powder cabinet purges the storage atmosphere with inert gas, while tightly controlling temperature and humidity.  
  • ADDvance O2 precision atmosphere monitoring system precisely controls O2 and humidity levels by continuously analyzing the powder chamber atmosphere.
  • Linde ADDvance Cryoclean cleaning technology uses CO2 snow plus blasting abrasives to remove difficult residues cost-effectively and without water.

 Press Releases

  • Bridgewater, N.J., U.S., February 2, 2018Linde LLC will showcase three new technologies to improve the quality of metal additive manufacturing (AM) at RAPID+TCT 2018 in Fort Worth, Texas, April 24-26, booth #1347.

    “Reproducible quality is the ultimate goal of additive manufacturing,” said Grzegorz Moroz, Program Manager, Metals, Linde LLC. “Variations in processes and materials can impact part quality and performance, so Linde works with manufacturers of aerospace, automotive and medical components to reduce or eliminate variations at every step. These industries demand documented consistency in AM processes, and Linde offers gas-based technologies and know-how to help meet strict quality requirements.”

    As a global leader in industrial gases and technology, Linde collaborates with universities and manufacturers, such as Airbus Group Innovations, to improve Additive Manufacturing processes. In addition, Linde opened an Additive Manufacturing global R&D Center near Munich in 2016, where the laboratory is focusing on the effect of atmospheric gases and gas mixtures on metal powders to optimize layering processes during 3D printing.

    The novel Linde gas-based technologies to be showcased at RAPID include the following:

    Incoming Quality: High-end Additive Manufacturing depends not only on the incoming quality of metal powders, but also on storage conditions of sensitive powder metals such as aluminum or titanium alloys before use. The ADDvance® powder cabinet purges the storage atmosphere with inert gas, while tightly controlling temperature and humidity.

    3D Process Quality: Unwanted gases can enter an AM chamber in several ways -- through insufficient purging, loose supply connections, or through the powder metal itself. The Linde ADDvance O2 precision atmosphere monitoring system precisely controls O2 and humidity levels by continuously analyzing the powder chamber atmosphere. The portable unit is ideal for powder-bed laser fusion processes.

    Finish Quality: Surface oxides, unfused powders, or other residues need to be removed from AM parts prior to further processing or surface finishing. Linde ADDvance Cryoclean cleaning technology uses CO2 snow plus blasting abrasives to remove difficult residues cost-effectively and without water.

  • ADDvance O2 Precision
    The ADDvance® precision O2 atmosphere control unit from Linde can improve the reproducibility of advanced metal parts produced in powder-bed processes by controlling the level of oxygen and humidity in the print chamber atmosphere....

  • Linde worked with Airbus Group Innovations in engineering the new technology, first introduced in 2016, and now proven in use by manufacturers. “ADDvance O2 precision is easy to use and can make an immediate impact on metal 3D printing processes here, too,” Moroz said.

    Reproducible quality of powder-metal 3D printed parts is essential for advanced aerospace, automotive and medical applications. Yet aluminum and titanium alloys are extremely sensitive to oxygen (O2) and humidity levels in the atmosphere of the 3D process chamber. Controlling these helps prevent powder oxidation and uneven fusion that could impact final mechanical properties such as tensile strength and fatigue resistance. It also avoids discoloration and surface defects.

    How it Works

    Unwanted gases can enter a 3D print chamber through insufficient purging, minor breaches in system integrity, or through the powder metal itself. The compact ADDvance O2 unit precisely controls O2 and humidity levels by continuously analyzing the metal printer atmosphere. It can detect O2 concentrations down to 10 ppm along with relevant oxidation potential, and automatically controls the flow of inert gas to maintain desired atmosphere purity.
