ADDvance™ O2 precision is a measuring and analysis unit that will enable metal additive manufacturers to more precisely analyze and control the level of oxygen and humidity within the printer chamber. The technology can detect oxygen levels up to 10 parts per million (ppm) within the printer chamber and then modify the gas atmosphere by adjusting the level of argon or nitrogen. The presence of too much oxygen or humidity can pose a challenge to additive manufacturers as it can negatively impact the quality and performance of the item being printed.
