This PFI: AIR Technology Translation project focuses on translating an Additive Manufacturing technology called Selective Inhibition Sintering (SIS) to fill the gap for an inexpensive and capable 3D Printer for fabrication of metallic parts. Currently all metallic part printers are highly priced and are unaffordable by small manufacturing firms as well as by the growing maker community which is increasingly becoming the source of much innovation in the U.S.The translated technology has the following unique features: a) It will be an order of magnitude less expensive than current metallic part printers, b) it can process very high temperature metals and alloys such as super alloys which have extensive uses, and c) it can build a large number of parts concurrently hence is suitable for small to medium lot size manufacturing. The technology provides exemplary cost effectiveness and high throughput when compared to the leading competing technologies (such as DMLS, EBM, and LENS) in this market space. The project accomplishes this goal by a systematic research, development and experimentation process resulting in a reliable process knowledge and a pre-production machine that can be mass produced at low cost and will be able to print precise parts out of a variety of metals and alloys. The partnership engages RapidTech, ASCO Sintering, ProMetal and 3D Systems to provide guidance in the technical aspects of metallic AM domain and other aspects of commercial relevance as they pertain to the potential to translate the technology along a path that may result in a competitive commercial reality. The potential economic impact is expected to be over $30M in two years after the commercial introduction of the technology and much more in the succeeding years, which will contribute to the U.S. competitiveness in the rapidly growing metallic Additive Manufacturing market space. The societal impact, long term, will be paramount as the proposed project will yield an affordable machine that will be capable of rapidly fabricating parts out of bronze, stainless steel, and titanium as well as other metal powders generally used in powder metallurgy. Practical uses of such a technique includes fabrication of functional parts for the aerospace and automotive industries, and custom design parts for medical devices, primarily using hard-to-machine materials such as stainless steel, titanium and super alloys. The SIS process will be particularly useful for the conventional powder metallurgy industry because it can eliminate the need for fabrication of expensive molds. Finally, metallic 3D Printing has so far been out of the reach of the growing maker community. SIS has the promise of making the needed capability available to this creative community which is already making significant economic and social impact in the US.

该PFI：AIR技术翻译项目的重点是翻译一种名为选择性抑制烧结（SIS）的增材制造技术，以填补用于制造金属零件的廉价且功能强大的3D打印机的差距。 目前，所有金属零件打印机的价格都很高，小型制造公司以及不断增长的制造商社区都无法负担，而制造商社区正日益成为美国许多创新的源泉。a）它将比当前的金属零件打印机便宜一个数量级，B）它可以处理非常高温的金属和合金，例如具有广泛用途的超级合金，以及c）它可以同时制造大量的部件，因此适合于小到中等批量的制造。与该市场领域的领先竞争技术（如DMLS、EBM和透镜）相比，该技术提供了示例性的成本效益和高吞吐量。 该项目通过系统的研究，开发和实验过程实现了这一目标，从而获得了可靠的工艺知识和预生产机器，该机器可以低成本大规模生产，并能够用各种金属和合金打印精确的零件。 该合作伙伴关系涉及RapidTech、ASCO Sintering、ProMetal和3D Systems，为金属AM领域的技术方面和其他商业相关性方面提供指导，因为它们涉及沿着可能导致竞争的道路转化技术的潜力商业现实。 在该技术商业化引入后的两年内，潜在的经济影响预计将超过3000万美元，并在随后的几年内进一步扩大，这将有助于提高美国在快速增长的金属增材制造市场空间中的竞争力。 长期的社会影响将是至关重要的，因为拟议的项目将产生一种负担得起的机器，能够快速制造青铜，不锈钢和钛以及粉末冶金中常用的其他金属粉末的零件。这种技术的实际应用包括制造航空航天和汽车工业的功能部件，以及医疗设备的定制设计部件，主要使用难以加工的材料，如不锈钢，钛和超级合金。SIS工艺对于传统的粉末冶金工业特别有用，因为它可以消除制造昂贵模具的需要。最后，金属3D打印到目前为止还不在不断增长的制造商社区的范围内。SIS有希望为这个创造性的社区提供所需的能力，这个社区已经在美国产生了重大的经济和社会影响。
