NAMII awarding $9M to 15 additive manufacturing projects

America Makes, the National Additive Manufacturing Innovation Institute (NAMII), recently announced the awardees of its second call for additive manufacturing (AM) applied research and development projects from its members. Driven by the National Center for Defense Manufacturing and Machining (NCDMM), America Makes will provide $9 million in funding toward these 15 projects with $10.3 million in matching cost share from the awarded project teams for total funding worth $19.3 million.

Combined with the projects underway from its first project call, America Makes will soon have nearly $30 million of public and private funds invested in advancing additive manufacturing in the United States, said America Makes Director and NCDMM Vice President Ed Morris.

The Institute’s second project call, which was released on 30 August 2013, was focused on AM materials; process and equipment; qualification and certification; and knowledgebase development-each with subset focus areas. Proposals could address one or more technical topic areas, but had to address all evaluation criteria.

The 15 selected projects span a variety of AM processes and materials with near-term technical achievements that address a comprehensive set of priorities-needs, gaps, and opportunities-within the AM and 3D printing industry. The projects represent teaming within the America Makes community and beyond.

Of the 75 individual partners among the 15 selected projects, 31 are America Makes members, including four Platinum (Lead) members, 15 Gold (Full) members; and 12 Silver (Supporting) members.

Subject to the finalization of all contractual details and requirements, the 15 selected America Makes projects are as follows:

Development of a Low-Cost Lens® Engine.
This project will enable a broad proliferation of metal AM through the development of a modular, cost-effective “LENS® Engine” for metal laser deposition, which can be installed into virtually any modern machine tool. To reach this goal, the latest in controls, toolpath generation, and quality monitoring are to be embedded in a modular design that can be easily upgraded and maintained as part of a machine tool system.
(Applied Optimization Inc.)
Development of Knowledgebase of Deposition Parameters for Ti-6Al-4V and IN718.
This project will offer an efficient and reusable solution to define process parameters that result in defect-free deposition in metallic AM. The knowledgebase will consist of a matrix of permissible combinations of process parameter values that may be used in order to produce defect-free additive deposits using the LENS process. The knowledgebase will provide a process engineer the ability to select from a matrix of vetted process parameter combinations and minimize/eliminate the trial-and-error or cut-and-try approach to process development. The knowledgebase will be generated for two alloys of interest, Ti-6Al-4V and IN718.

Optimization of Parallel Consolidation Method for Industrial Additive Manufacturing.
This project will continue development of a novel method for AM by consolidating powder at many points on a part simultaneously. Materials and process data relating to the parallel consolidation method will be captured in a knowledgebase in a format consistent with the America Makes national repository framework. The knowledgebase will be complemented by online training, workforce development, and publication initiatives to disseminate information about the project’s results and support transition to commercial adoption.

The anticipated start date of the second set of projects is early Spring 2014. America Makes will conduct a Program Management Review for members only on 18-20 March in Youngstown, Ohio. The review will include overviews of the new projects being awarded.
