澳洲硕士论文代写：增材制造的概况。研究发现，AM已经经历了指数增长的有机形式。可以说，全球大多数人对增材制造的兴趣源于早期使用3D打印实现快速原型。因此，为了规范术语，我们进行了大量研究。ASTM F-42委员会制定了一项称为ASTM F2792-10的标准，以定义AM是一种过程，其中材料以一层一层的方式加入，以从3D模型数据中生成物理目标，并与减法制造技术形成对比。接下来澳洲硕士论文代写专家将为同学们分析下增材制造的概况。
这一定义导致了从添加剂制造和自由成形制造到添加剂层制造和层制造的技术同义词的出现。由此可见，由于应用的性质不同，不同的AM技术和方法已经出现并得到普遍采用(Lewandowski和Seifi, 2016)。研究人员认为，增材制造为消费者和专业人士提供了类似的服务，使他们不仅能够创造和定制产品，而且还能在生产过程中修复产品，重新定义现有的生产技术。
研究表明，通过理解现在仅使用金属粉末就可以将复杂的金属零件开发到最高质量标准，就可以实现金属零件增材制造的国际前景。因此，AM用于跨应用程序生产最苛刻的组件数量。
通过空客飞机制造商的例子，我们可以了解国际技术格局。空客飞机的标准结构件采用了快速熔模铸造与直接金属激光烧结(DMLS)的结合。在本例中，添加层制造技术被用于为空客飞机生产带支架的串联生产A350 XWB塔架。
空客A320neo和A350 XWB测试飞机已经在进行试飞，并使用了3D打印的金属部件，这是飞机运行所必需的。该技术已被用于实现飞机的快速生产，降低成本，提高质量和一致性。
研究表明，2015年全球金属3D打印机的销量增长了45%。这一表述表明，在不同国家，金属3D打印机制造商的数量在技术的使用和采用以及成本方面存在差异。多达6家制造商位于美国，其次是5家制造商在德国(Manfredi et al.， 2013)。中国和日本都有4个制造商，其他国家都有一个制造商。研究发现EOS机器被组织广泛使用的原因之一是它是销售基于金属的3D打印机的市场领导者。可以看出，EOS公司在2015年卖出了500台金属3D打印机，收入为1.88亿美元。
This definition resulted in the number of technological synonyms to emerge from additive fabrication and freeform fabrication to additive layer manufacturing and layer manufacturing among more. From this it can be implied that the different AM technologies and methods have emerged and gained prevalent adoption due to the distinct nature of application (Lewandowski and Seifi, 2016). The researchers have argued that it is the additive manufacturing that provides the consumers and professionals with the similar service, degree of accessibility to not only create and customize products but also repair them and redefine the existing technologies of production during the process.
The research has indicated that the international landscape of additive manufacturing for the metal parts can be realized by understanding that the complex metal parts can now be developed to the highest quality standards merely with the use of metal powders. Thus, the AM is used for the production of number of components across the applications that are most demanding.
An example of the Airbus aircraft manufacturer can be taken to understand the international landscape of the technologies. Combination of the rapid investment casting along with the direct metal laser sintering (DMLS) was used for the standard structural part of the Airbus aircraft. In this example, additive layer manufacturing technology was used to produce an in-series production A350 XWB pylon with bracket for the Airbus aircraft.
The Airbus A320neo and A350 XWB test aircrafts are already undergoing test flights and using the 3D printed metal parts that are required for the aircraft to function. This technology has been used to enable rapid production of the aircraft, reduction of the cost and increase in quality and consistency.
The research has indicated that the global sales of the metal based 3D printers have increased by 45 percent in 2015. This expression indicates that the number of metal 3D printer manufactures present across the different nations vary in terms of the use and adoption of technology along with the cost. As much as 6 manufactures are located in United States followed by 5 manufacturers in Germany (Manfredi et al., 2013). Both China and Japan consists of 4 manufacturers each followed by other nations with one manufacturer. It was identified from the research that one of the reason behind machines of EOS to be widely used by the organizations is that it is the market leader in the sales of metal based 3D printers. It can be implied that as much as 500 units of Metal 3D printers were sold by the EOS Company in 2015 with the revenue of $188 million.
