The aim of this proposal is to develop novel high performance, nanocomposite feed materials for Additive Manufacturing (AM). The field of AM, also known also as 3D Printing, has expanded significantly over the last couple of decades across virtually all-industrial sectors due a number of key advantages that traditional manufacturing just cannot offer. These include mass customisation, geometrical complexity, tool-less manufacture and sustainable manufacturing. Among the companies using AM are GE (medical devices, and home appliance parts), Lockheed Martin and Boeing (aerospace and defense), Invisalign (dental devices) and LUXeXcel (lenses for light-emitting diodes, or LEDs). The worldwide revenue from 3D printing is expected to grow from $3.07 billion in 2013 to $12.8 billion by 2018, and exceed $21 billion by 2020, and has a potential of generating an economic impact of $230 billion to $550 billion per year by 2025. While the forecast for AM products is huge this will only be achieved if we can actually manufacture parts with the desired properties. The majority of polymeric AM research is however focused on low glass transition temperature (Tg) polymers such as Polyamide 11, 12 , Polycarbonate and Poly Lactic acid (PLA), due to their good processing characteristics (rheological, thermal and crystallization). For advanced, high value applications in aerospace, telecommunication and defense where harsh environmental conditions often exist (and in some key biomedical application) these low Tg polymers for AM are not acceptable so there is a real need to develop materials for these applications. Whilst a sufficiently high Tg polymer could offer the required high performance, nanocomposites with increased functionalities and potential combinations of properties such as high stiffness, strength, wear and specific thermal, electrical and microwave response can really transform the performance of AM components. The ability to manipulate other properties, such as rheological and thermal performance, by the addition of nanoparticles offers further potential advantages in terms of processing characteristics. This proposal will examine the potential of inorganic fullerene-like (IF) tungsten disulfide (WS2) or IF-WS2 as nanofillers for high value, PAEK (Poly Aryl Ether Ketone) based products made via the AM processes of Selective Laser Sintering (SLS) and Fused Deposition Modelling (FDM). The incorporation of IF particles has been shown to be efficient for improving thermal, mechanical and tribological properties of various thermoplastic polymers, such as polypropylene, nylon-6, poly(phenylene sulfide), poly(ether ether ketone). These nanocomposites were fabricated by simple melt-processing routes without the need for modifiers or surfactants . IF-WS2 have been proven to exhibit extremely high tribological performance in composites to reduce wear and coefficient of friction .These characteristics will also have important processability benefits for AM processes as will their dispersion characteristics which are superior to 1D and 2D nanoparticles. They are also the best shock absorbing cage structures known to mankind. Importantly, they are non-toxic, and thermally stable. We will examine the two main AM processes for producing parts with engineering properties, Selective Laser Sintering (SLS) in which a laser is used to melt and sinter powdered polymer into the final part and Fused Deposition Modelling (FDM) in which a polymer filament is melted in a heated nozzle and deposited in the required pattern to form the part.

该提案的目的是开发新型的高性能，纳米复合材料用于添加剂制造（AM）。由于传统制造业无法提供的许多关键优势，AM的领域也被称为3D打印，在过去的几十年中，在过去的几十年中已经大大扩展了。其中包括大规模定制，几何复杂性，无工具制造和可持续制造。在使用AM的公司中，有GE（医疗设备和家用电器零件），洛克希德·马丁和波音公司（航空航天和国防），Invisalign（牙科设备）和Luxexcel（发光二极管或LED的镜头）。全球收入从3D印刷的收入预计将从2013年的30.7亿美元增长到2018年的128亿美元，到2020年超过210亿美元，并有可能在2025年产生203亿美元的经济影响到每年5,000亿美元，到2025年。然而，大多数聚合物AM研究集中在低玻璃过渡温度（TG）聚合物（例如聚酰胺11、12，聚碳酸酯和聚乳酸（PLA））上，因为它们的良好加工特征（流变学，热和结晶）。对于经常存在恶劣的环境条件（并且在某些关键的生物医学应用中）的高级，高价值应用，电信和防御，这些低的TG聚合物对于AM是不可接受的，因此真正需要为这些应用开发材料。尽管TG聚合物足够高，可以提供所需的高性能，但具有增加功能和潜在属性组合的纳米复合材料，例如高刚度，强度，磨损以及特定的热，电气和微波反应确实可以改变AM组件的性能。通过添加纳米颗粒来操纵其他特性的能力，例如流变和热性能，在处理特征方面具有进一步的潜在优势。该提案将检查无机富烯样（IF）二硫化钨（WS2）或if-WS2作为高价值的纳米漏斗，Paek（多芳基醚酮）基于选择性激光固定（SLS）和融合融合的Deposign型模型（FDM）制造的基于AM的Paek（Poly Aryl-Ether Ketone）产品。 IF颗粒的掺入已被证明可以有效地改善各种热塑性聚合物的热，机械和摩擦学特性，例如聚丙烯，尼龙-6，聚（苯基硫化物），聚（醚醚酮）。这些纳米复合材料是通过简单的熔融加工路线制造的，而无需修饰剂或表面活性剂。如果已证明WS2在复合材料中表现出极高的摩擦学性能，以减少摩擦的磨损和系数。这些特征也将对AM过程具有重要的加工性益处，其分散特征将比1D和2D纳米颗粒较高。它们也是人类已知的吸收笼子结构的最佳冲击。重要的是，它们是无毒的，并且热稳定。我们将研究两个主要AM过程，用于生产工程特性，选择性激光烧结（SLS），其中激光用于将激光融化和烧结粉末状聚合物中的最终部分以及融合的沉积模型（FDM），其中聚合物丝中的聚合物丝中以加热的喷嘴融化，并在所需的模式中融化，以形成零件。
