传统制造方法的使用主要受限于生产运行的规模和部件的几何复杂性，因此我们有时被迫使用增加所生产元件的最终成本的工艺和工具。附加制造技术提供了主要的竞争优势，因为它们适应了要制造的零件的几何复杂性和定制设计。根据应用领域，还可以实现以下目标：更轻的产品、多材料产品、符合人体工程学的产品、高效的短生产、更少的装配错误，因此，更低的相关成本、更低的工具投资成本、不同制造过程的组合、材料的优化使用以及更可持续的制造过程。加法制造被视为未来几年的主要革命性工业工艺之一。加法制造有几种选择，从简单的RepRap机器到复杂的熔融金属沉积系统。本文将对机械的结构设计、它们的历史、分类、目前存在的替代方案、所使用的材料及其特点、技术限制以及在专业创新领域和学术研究领域为不同技术开辟的前景展开论述。必须指出的是，技术的选择直接取决于正在规划的特定应用程序：首先是应用程序，然后是技术。
The use of conventional manufacturing methods is mainly limited by the size of the production run and the geometrical complexity of the component, and as a result we are occasionally forced to use processes and tools that increase the final cost of the element being produced. Additive manufacturing techniques provide major competitive advantages due to the fact that they adapt to the geometrical complexity and customised design of the part to be manufactured. The following may also be achieved according to field of application: lighter weight products, multimaterial products, ergonomic products, efficient short production runs, fewer assembly errors and, therefore, lower associated costs, lower tool investment costs, a combination of different manufacturing processes, an optimised use of materials, and a more sustainable manufacturing process. Additive manufacturing is seen as being one of the major revolutionary industrial processes of the next few years. Additive manufacturing has several alternatives ranging from simple RepRap machines to complex fused metal deposition systems. This paper will expand upon the structural design of the machines, their history, classification, the alternatives existing today, materials used and their characteristics, the technology limitations, and also the prospects that are opening up for different technologies both in the professional field of innovation and the academic field of research. It is important to say that the choice of technology is directly dependent on the particular application being planned: first the application and then the technology.
