Special Issue Information

Dear Colleagues,

Three-dimensional (3D) printing is a process that uses computer-aided design (CAD) data to achieve the continuous layered deposition of different shapes to produce 3D objects. Consequently, 3D-printed objects can have any geometric shape(s) and features. Thanks to this feature, 3D printing has been applied in numerous industries in which the traditional manufacturing processes are relatively complex, have long cycle times, and struggle to maintain precision. The applications of 3D printing technologies have overcome these problems to reduce manufacturing costs and shorten cycle times.

This Special Issue is focused on the application of 3D printing in the aircraft industry. The applications of 3D printing in the aircraft industry differ from those in other industries in the following aspects: oligopoly, project-based production, long cycle times, and the pursuit of lighter products. Nevertheless, to date, 3D printing, as a green production technology, has benefitted the aircraft industry with shortened cycle times, reduced production costs, and lighter component weights. In particular, the light weight of airplanes reduces fuel consumption and in turn elevates profitability. In addition, the aviation market demands that spare parts be delivered rapidly. By 3D printing spare parts domestically, the need for transporting spare parts to meet the local demand is eliminated; thereby, the cycle time can be dramatically shortened.

Topics of interest include, but are not limited to:

  • 3D printing applications to test functional spare parts;
  • 3D printing applications to generate prototypes;
  • 3D printing applications to evaluate the machinability of molds;
  • 3D printing applications to making molding models;
  • 3D printing applications to mimic natural structures in making aircraft parts;
  • 3D printing applications to optimize the design of the structure;
  • 3D printing applications to make spare parts for aircraft maintenance;
  • 3D printing applications to make an entire drone or unmanned aerial vehicle;
  • 3D printing applications to create a global supply chain of spare parts;
  • 3D printing applications to monitor the structural conditions of aircraft;
  • 3D printing applications to the lightweight of airplanes;
  • How can we 3D print an entire airplane?
  • How can intellectual property rights be protected?
  • New measures for evaluating maintenance and repair performance;
  • New methods for making airplanes;
  • New materials for making airplanes;
  • Potential for new airplane designs;
  • Globalization and deglobalization;
  • Lowering the entry threshold for the aircraft maintenance market;
  • Inspection and testing applications for 3D-printed aircraft parts;
  • Battlefield applications;
  • Other related topics.

As a viable means to enhance the sustainability and competitiveness of aircraft manufacturing and maintenance, three-dimensional (3D) printing has been extensively used in the aircraft industry. However, due to the growing number of suitable 3D printers and the often-high prices of these 3D printers, aircraft manufacturers still face many obstacles in screening possible 3D printers. In addition, dependencies between criteria make it difficult for decision makers to properly assess their absolute priorities. Existing methods fail to address these issues. To solve this problem, this study proposes a nonlinear fuzzy geometric mean (FGM) and dependency-considered fuzzy vise kriterijumska optimizacija i kompromisno resenje (fuzzy VIKOR) approach. The first novel treatment is to design the nFGM method to ensure that the absolute priorities assigned to criteria are correct. Subsequently, in the dependency-considered fuzzy VIKOR, the dependencies between criteria are considered, and a realistic reference point is defined by measuring the distance from each 3D printer to it for proper evaluation. The nonlinear FGM and dependency-considered fuzzy VIKOR approach has been applied to assess and compare five 3D printers for manufacturing aircraft components. Full article
