ExOne Company, a manufacturer of industrial sand and metal 3D printers using binder injection technology, has announced that it will offer a controlled atmosphere model of its X1 160Pro Extra Large Production Metal Printer in the second half of 2022.


The X1 160Pro, with a build box of 800 x 500 x 400 mm, or 160 liters, is ExOne’s 10th and largest production-ready metal binder jetting system to date. The new model is now shipping from the company’s European headquarters and production facility in Gersthofen, Germany.


A controlled atmosphere is essential for 3D printing of reactive fine metal powders, but it also offers other benefits, such as reduction of powder oxidation and enhanced powder dispensing and spreading through control of humidity. This update will smooth the way for high-volume production of aluminum, titanium, copper, and several other materials using binder jet 3D printing technology.


ExOne has successfully been binder jetting reactive powders in controlled atmospheres, also sometimes referred to as inert or chemically inactive, for years. On Dec. 1, 2020, ExOne was issued a patent on binder jet 3D printing in a controlled atmosphere.


ExOne’s controlled-atmosphere X1 160Pro can be used with nitrogen or argon and will be paired with accessories and ancillary equipment also equipped with inert atmosphere features. These include a curing oven, powder conditioning system, depowdering station, and transport device for moving the build-box between process stages to ensure complete atmosphere control throughout the process.


Importantly, ExOne will continue to offer the original model of the X1 160Pro, a streamlined model for customers who do not need a controlled atmosphere system to process metal powders such as stainless steels. ExOne customers currently use the X1 25Pro® metal binder jet system for production today without an inert feature, with one customer now operating six of the systems for serial production.


ExOne binder jet 3D printing technology is capable of processing 23 metal, ceramic, and composite materials, including a dozen single-alloy metals such as aluminum and titanium.
