Since 1995, we’ve been on a mission to deliver powerful 3D printers that solve the toughest problems and enable world-changing innovations. Our industrial 3D printing systems quickly transform granular materials — including silica and ceramic sand as well as reclaimed materials like re-pulverized concrete and wood pulp — into precision metalcasting molds and cores, innovative rapid tooling solutions, as well as functional end-use designs for consumer products and architectural restoration.
Industrial customers use our technology to:
As part of the Desktop Metal family, ExOne is home to the world’s leading team of sand binder jetting experts. To realize the #TeamDM vision of bringing Additive Manufacturing 2.0 technologies for volume production to the market, ExOne offers a range of systems and services to integrate 3D printing into customers’ operations.
Binder jetting is a method of 3D printing in which an industrial printhead quickly deposits a liquid bonding agent onto a thin layer of powdered particles, such as foundry-grade silica or ceramic sand as well as waste stream materials like re-pulverized concrete, upcycled sawdust, and reclaimed coffee. The process is repeated layer by layer, using a map from a digital design file, until the object is complete.
Initially developed at the Massachusetts Institute of Technology in the early 1990s, ExOne obtained the exclusive license to this inkjet-in-powder-bed method of 3D printing in 1996.
Two years later, ExOne launched the market’s first commercial binder jet 3D printer for metals, the Rapid Tooling System known as RTS-300. In 2002, ExOne launched its first sand 3D printer, the S15.
Debuting in 2010, the S-Max series became the world’s leading sand binder jetting machines. After the acquisition by Desktop Metal in 2021, ExOne focused on expanding adoption of sand 3D printing in foundries, for tooling applications, and with innovative infiltrated designs that reduce lead times and costs.
