“…AM is more cost-effective for low volume productions as it does not need supporting fixtures and tooling to produce the required parts. This pushes AM into the spotlight as low production runs are often commonplace, particularly if customers need one-off products [10]. The United States Air Force (USAF) has partnered with America Makes, an American-based AM innovation institute, with the objectives of supplying on-demand production in and reducing lead times for replacement and maintenance components of legacy aircrafts [137].…”

“…In the aerospace industry, AM is specifically experiencing a continuingly upward trend of utilization in the fabrication of various individual aircraft components which accounted for 16.6% and 18.2% of the global industry market share in 2016 and 2017, respectively [9,10]. One of the major reasons for this is the prospect of redesigning and manufacturing parts on demand with significant mass…”

Metal additive manufacturing (AM) has matured from its infancy in the research stage to the fabrication of a wide range of commercial functional applications. In particular, at present, metal AM is now popular in the aerospace industry to build and repair various components for commercial and military aircraft, as well as outer space vehicles. Firstly, this review describes the categories of AM technologies that are commonly used to fabricate metallic parts. Then, the evolution of metal AM used in the aerospace industry from just prototyping to the manufacturing of propulsion systems and structural components is also highlighted. In addition, current outstanding issues that prevent metal AM from entering mass production in the aerospace industry are discussed, including the development of standards and qualifications, sustainability, and supply chain development.

“…This process allows producing precise geometric shapes in the bottom-up method [3]. In recent years, there has been an increasing interest in AM technology to be used in different industries, such as automotive, aerospace and medicine [4,5]. The motivation for this interest is because of the flexibility in design and rapid productivity of metal AM technologies in the building of the complex and high-value parts in a single step [6].…”

Directed energy deposition (DED) process is recognized as an alternative technology to produce the complex-shape AISI 316L components. The critical production step in this technology is the optimization of process parameters that can directly affect the final properties of the components. To optimize the process parameters, the residual defects of specimens produced with different combinations of process parameters are evaluated, and the optimum condition is chosen. Therefore, the residual defects assessment is a vital step in finding the optimum process parameters; therefore, this evaluation should be carried out carefully. One of the main issues in the production of AISI 316L by DED process is oxidation during the process that should be considered besides the other defects such as porosity and cracks. However, the identification between the oxides and porosities is not an easy task, and so this study aims to provide more clear insight into the evaluation of pores and oxides in DED 316L samples. The outcomes of this work show that at the best process parameters suitable for a porosity-free sample, there are some oxides that can be misinterpreted as porosity and consequently deteriorate the mechanical properties of the dense sample.

“…Although additive manufacturing (AM) has existed for decades and has already revolutionized the production of polymeric material components, new AM technology developments are providing industries with the possibility of building structural components with a variety of metal alloys, ceramics, and composite materials. The major drivers of interest (Table A1 in Appendix A) that have led to the introduction of metal AM processes in such industrial sectors as the aerospace [1], automotive, defense, jewelry, medical [2], and tool making [3] fields, are the significant reduction in the lead times of the components, innovative designs with higher strength, lower weight and fewer potential failure points from joining features, and reduction of waste material [4,5].…”

A Metal Powder Bed Fusion Process in Industry: Qualification Considerations

2019

View full text Add to dashboard Cite

An additive manufacturing process should produce repeatable results as far as the properties of the material and the geometric dimensions that have to be adopted by a company as a production method are concerned. This represents a challenge for such high-volume sectors as the automotive industry, where quality and reliability are extremely important. One way of addressing this challenge is to qualify the process. A common framework has here been identified starting from the analysis of the factors that influence the stability of the result in the main phases of metal powder bed fusion (PBF) processes. A qualification procedure (QP), which offers possible solutions to help reduce risk factors, has been proposed. This procedure is independent of the industrial sectors, of which type of materials and metal PBF processes, and of the manufacturer of the used PBF system.
