At ExOne, We've Always Been Green

From our inception as the 3D printing division of Extrude Hone in 1995, ExOne has always been focused on the sustainability benefits that binder jetting delivers.

We might not have used the popular sustainability buzzword back then, but reducing the waste associated with traditional manufacturing processes and improving design freedom has driven us from the beginning.

That’s why the ExOne logo has always been green, and it’s why our R&D teams have been working so diligently for more than two decades to advance this technology.

So, why is binder jetting so sustainable?

  • Binder jetting fabricates using a wide range of powdered materials, local material sourcing that reduces logistics and enabling new material innovations. Waste stream materials like re-pulverized concrete, upcycled sawdust, and reclaimed coffee grounds can be repurposed into new products with the material flexibility our technology.
  • All-new lightweight designs that were not previously manufacturable are possible with binder jetting. That helps cars, planes and other heavy equipment consume less energy. Customers routinely reduce the weight of their parts by 30-40% using our technology.
  • New designs enabled by binder jetting technology can deliver meaningful part consolidation that reduces waste and energy consumption along the entire supply chain.
  • Binder jet 3D printing, because of its material and geometry flexibility, allows users to produce a variety of parts without traditional hard tooling. This, in turn, can enable more distributed manufacturing, closer to the point of use, which reduces energy consumption for shipping and de-risks supply chains. 
  • By eliminating traditional tooling requirements, manufacturers produce volumes more aligned with actual market needs, without having to inflate volumes to cover tooling costs. This prudent approach could eventually have a dramatic impact on current manufacturing business models, which often requires artificially high production and consumption to justify tooling investments.
  • ExOne's most popular binder, furan, is made from renewable sources, such as corn husks, rice hulls, sugar cane, and other biomaterials.
  • Our inorganic binder uses a water-based geopolymer binder free of petroleum-based solvents and other volatile organic compounds (VOCs) — eliminating organic emissions during metalcasting.
  • ExOne's washout tooling is a true sustainability innovation. This sacrificial tooling for composite layup is 3D printed in sand and washes out with simple tap water. No hot solvents, deflatable tooling, or breakout needed. 3D print your form as complex as you like, process and autoclave at high temps up to 180°C (356°F). Then, simply wash the tool away with water and recycle the sand. 

Yes, it’s true that other 3D printing methods also reduce waste and offer some of these benefits, such as design freedom.ExOne - Proud Founding Member

So, here’s what makes binder jetting truly unique: We can deliver all these benefits at speeds and volumes that are unmatched by other additive manufacturing technologies. 

In other words, we can bring the benefits of 3D printing to a production environment at scale, delivering sweeping improvements that truly make a difference. ExOne delivers more sustainable parts made with sustainable technology in high volumes.

At ExOne, our entire global team is proud to offer a green, progressive manufacturing technology — because we believe technology has a role to play in solving the world’s toughest problems.

Whether you print, pour or produce with ExOne’s binder jetting technology, you can rest assured that you’re 3D printing a better future.
