ExOne is an international leader in industrial sand and metal 3D printers by the use of binder jetting technology. The company has today declared that 15 fresh metal, composite and ceramic materials have been approved by ExOne and its clients for additive manufacturing on the firm’s group of metal 3D printers.

The additionals will allow the owners of ExOne metal 3D printing machines to print 21 approved materials:
- Ten single-alloy metals,
- 6 ceramics
- 5 composite materials.
Over 24 extra powders have been approved for additive manufacturing in regulated research and growth environments. This includes Inconel 718 and aluminum.
ExOne’s special adhesive jetting technology, in progress since 1996, changes powdered stuff into solid and working accurate pieces at high paces. Binder jetting is a technique of additive manufacturing in which a modern printhead keeps a fluid binder onto a slim sheet of powdered bits, level by level, till the object is created.
“ExOne continues to make aggressive and outstanding progress in qualifying new materials for 3D printing on our machines,” stated the CEO of ExOne John Hartner.
“Qualifying a new material for binder jet 3D printing is complex work that involves optimizing how materials, machines, and processes work together. We would like to thank our customers and partners for their assistance in accelerating this important work, which is enabling more sustainable manufacturing and part designs,” he added.
Associates that have helped ExOne in approving materials consists of;
- Global Tungsten & Powders,
- Oak Ridge National Laboratory,
- H.C. Starck Solutions, NASA, SGL Carbon,
- The U.S. Department of Energy, the U.S. Army
- The University of Texas at El Paso, and Virginia Tech.
Above all, the clients of ExOne are currently additively manufacturing over one dozen varying elements for R&D, production, prototypes, as well as proprietary elements.
Binder jet additive manufacturing is a sustainable technique of metal piece manufacture since it fabricates things with small to no excess. This is also while enabling all-new light designs that were not earlier manufacturable.
Additionally, binder jetting is able to create pieces at high volumes and paces that may allow the widespread usage of this sustainable technology.
ExOne thinks that the capability to additively manufacture some materials at high speeds like aluminum will have a transformational sustainable influence on the aerospace and automobile sector.
“While our teams can binder jet aluminum in controlled R&D environments today, we believe that optimizing this material for high-speed 3D printing will eventually transform how car and airplane parts are made, making them smarter and lighter weight,” says the Chief Technology Officer of ExOne Rick Lucas.
“Based on high demand from the marketplace, we have fast-tracked development of this material for use on our machines,” he said.
ExOne also seeks to speed up the work by partnering with several manufacturing firms to optimize commercial additive manufacturing for aluminum.
