Aluminum and titanium printing The world’s largest metal binder jet 3D printer with a controlled atmosphere
In December 2020, Ex One was granted a patent for binder jet 3D printing in an inert atmosphere sufficient to enable processing of reactive materials. The role is to pave the way for 3D printing of high demand materials that require environmental controls.
The X1 160Pro is the world’s largest metal binder system and is now being delivered to customers. A model of the controlled atmosphere system capable of producing aluminum and titanium in large quantities will be available in late 2022.

Ex One, expert in binder jetting, announced that it will offer a model of its X1 160Pro oversized metal printer with a controlled atmosphere in the second half of 2022. The company’s largest metal 3D printer will provide a controlled atmosphere and enable aluminum and titanium production. The patented approach will be part of a complete inert production system.
A controlled atmosphere is essential for 3D printing reactive fine metal powders, but it also offers other benefits such as: B. a reduction in powder oxidation and improved powder delivery and distribution by controlling the humidity. This update will pave the way for the mass production of aluminum, titanium, copper and several other materials using Binder-Jet 3D printing technology.
Ex One has been successfully using reactive powders made from binders in controlled atmospheres, sometimes referred to as inert or chemically inactive, for years. In 2020, the company was granted a patent for Binder Jet 3D printing in a controlled atmosphere.
The X1 160Pro with controlled atmosphere can be used with nitrogen or argon and is combined with accessories and attachments that are also equipped with inert atmospheres. These include a curing oven, a powder conditioning system, a de-powdering station and a transport device for moving the kit between process stages to ensure complete control of the atmosphere throughout the process.
The manufacturer will continue to offer the original model of the X1 160Pro, an optimized model for customers who do not require a controlled atmosphere system for processing metal powders such as stainless steels. Ex-One customers currently use the X1 25Pro metal binder jet system for production without an inert function. A customer now operates six of the systems for series production. Ex One Binder Jet 3D printing technology can process 23 metals, ceramics and composites, including a dozen alloyed metals such as aluminum and titanium.
