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 subtractive manufacturing 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 metal, ceramic and composite objects out of powdered particles with little waste. It offers a dramatic improvement over traditional manufacturing, which generates enormous volumes of debris, often toxic, that must be cleaned and recycled, or put into landfills
  • Binder jetting enables all-new lightweight designs that were not previously manufacturable. That helps cars, planes and other heavy equipment consume less energy
  • The 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 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 hard tooling requirements, manufacturers can 3D print volumes that are more aligned with actual market needs, without having to inflate volumes to cover the cost of tooling investments. 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 for sandcasting molds and cores 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.

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 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.
