This SBIR Phase I project addresses the lack of materials available for advanced 3D printing. 3D printing is and will likely be used to produce products that encompass every aspect of day-to-day life. Current technology is primarily focused on the aerospace and medical fields. New metallic materials and more efficient processing methods are needed to transition to other more ubiquitous markets. This project is aimed at broadening the materials selection through a new production technique that complements existing technologies. The growth of the 3D printing industry will bring very competitive manufacturing jobs back to The United States.This project will investigate the feasibility of an innovative reactive additive manufacturing (RAM) process to create a range of materials including nickel metal matrix composites, tungsten carbide composites, and nickel titanium intermetallic compounds. Each material system will be designed, fabricated, and characterized for a range of properties including microstructure, product phases, density, porosity, and hardness. For each of the three materials systems, the iterative development process will include modification of composition and process parameters to determine their effect on the material microstructure and properties and determine the feasibility of the RAM process to produce each material type commercially. The expected outcome of this activity is that the RAM process will be proven feasible for one or more of the investigated materials systems. The results of this work will be developed further and will subsequently lead to commercialization and sales of the novel materials mixtures and RAM process parameters for use in commercial powder bed fusion additive manufacturing systems already in use.

该 SBIR 第一阶段项目解决了先进 3D 打印材料缺乏的问题。 3D 打印正在并将很可能用于生产涵盖日常生活各个方面的产品。当前的技术主要集中在航空航天和医疗领域。需要新的金属材料和更高效的加工方法来过渡到其他更普遍的市场。该项目旨在通过补充现有技术的新生产技术扩大材料选择。 3D打印行业的发展将为美国带来极具竞争力的制造业工作岗位。该项目将研究创新的反应增材制造（RAM）工艺的可行性，以制造一系列材料，包括镍金属基复合材料、碳化钨复合材料和镍钛金属间化合物。每种材料系统都将针对一系列性能进行设计、制造和表征，包括微观结构、产品相、密度、孔隙率和硬度。对于这三种材料系统中的每一种，迭代开发过程将包括成分和工艺参数的修改，以确定它们对材料微观结构和性能的影响，并确定 RAM 工艺商业化生产每种材料类型的可行性。这项活动的预期结果是 RAM 过程将被证明对于一个或多个所研究的材料系统是可行的。这项工作的成果将得到进一步发展，随后将导致新型材料混合物和 RAM 工艺参数的商业化和销售，用于已投入使用的商业粉末床熔融增材制造系统。
