Research & Development

Opportunities through partnership.

As the use of 3D Printing grows, ExOne relies on its partnerships to research the best use of materials and methods for printing. ExOne engineers have worked closely with students and faculties to investigate those issues which play a pivotal role in the additive manufacturing industry.

Various research organizations are also actively engaged with the ExOne® process and equipment, including national laboratories such as Oak Ridge, Lawrence Livermore, and NIST.   Other commercial research programs are being performed at both supplier and customer facilities, as well as multi-partnered research between public and private institutions.

America Makes

ExOne was on the original proposal team for America Makes, the first National Network for Manufacturing Innovation funded by the government and driven by the National Center for Defense Manufacturing and Machining. America Makes is focused on helping the United States grow capabilities and strength in 3D printing. Besides being a member of this organization, ExOne has served on the Governance Board, the Committee for Sustainability and is currently involved with a number of their funded programs including “Accelerated Adoption of Additive Manufacturing in the American Foundry Industry,” “Additive Manufacturing of Biomedical Devices from Bioresorbable Metallic Alloys for Medical Applications” and “Developing Topology Optimization Tools that Enable Efficient Design of Additive Manufactured Cellular Structures.”

University of Pittsburgh

University of Pittsburgh and ExOne engineers are working with the M-Flex® to explore options for creating the highest possible densification in parts and developing an ideal sintering process. This research is an on-going venture with ExOne with the goal of presenting their research proposal to the Nuclear Energy University Programs (NEUP). 

Virginia Tech

Virginia Tech is also conducting research with ExOne using the legacy R2™ printer in their DREAMS (Design, Research, and Education for Additive Manufacturing System) Lab. Faculty and students are investigating applications for additive manufacturing. Over the last year, they have been testing methods for printing in pure copper and its uses in electronics. Another aspect of their research includes identifying the potential for ceramics in parts creation. 

University of Louisville

University of Louisville currently uses the X1-Lab™ in multiple projects. In one such project, they are collaborating with the School of Dentistry of U of L to evaluate the printing of dental ceramic prostheses with proper geometrical and mechanical properties. In addition, U of L is working to fabricate and evaluate compositionally graded ceramic and metal parts. They are focusing on interfacial bonding strength and microstructural defects as a function of the printing and post-process parameters.

University of Northern Iowa

University of Iowa has created research that is industry focused in the areas of technology and materials development utilizing the S-Max™ printer system. Research and partnerships with the metal casting industry have made University of Iowa a proponent of economic growth. They utilize additive manufacturing processes to assist companies, such as Emerson Process Management, to make purchasing decisions that will eventually help to bring manufacturing back to the Midwest. ExOne’s S-Max™ system at the University of Iowa’s Metal Casting Center makes such projects possible.

University of Texas at El Paso

The University of Texas at El Paso researchers at the W.M. Keck Center for 3D Innovation are investigating topics from infiltration and binder processes to part density and materials using ExOne technology. UTEP has begun comparing the mechanical properties of infiltrated versus non-infiltrated parts using INC 625 and INC 718. In addition, they are experimenting with a closed-loop automatic feedback control of the binder jetting process using a digital single-lens reflex camera. Results from this research will lead to integrated metrology that will help users adjust for part geometry to account for shrinkage post-sintering as well as qualifying system fabrication by logging any prevalent fabrication errors. These projects are on-going as well as many others that are contributing to developments in ExOne technology.
