“…In recent years, studies have been carried out on integrated manufacturing methodologies for highly complex parts and high requirements for the aeronautical industry, combining additive processes for metal parts, such as LMD (Laser Metal Deposition) and CNC machining, in the same machine, covering all phases of the process, from design to final finish [5]. Some authors have proposed and studied the combination of alternated steps of AM and SM (subtractive manufacturing) from an integrated substrate, which allows providing better mechanical characteristics and reducing manufacturing time and costs in parts such as turbine blades [6] [7]. Others, in addition to pointing out the manufacture of metal parts with high added value for the aeronautical sector as the main field of future development of hybrid additive and subtractive manufacturing, limit the concept to the combination of additive and subtractive processes in a single machine, to obtain different and superior results to those possible through traditional processes, alone or in combination [8].…”

In recent years, hybrid additive and subtractive manufacturing has made its way as a new approach to manufacturing complex parts, with high added value and high requirements, imposed by the leading sectors of the industry, among which the aeronautical industry stands out. This still novel concept combines the additive manufacturing ability to generate parts with complex geometry and the great dimensional, geometric, and surface quality that allows the already mature subtractive manufacturing, and it does so by surpassing the concept of post-processing machining. Thus, the integration of both forms of manufacturing from the design phase of the parts to the final finish seeks to obtain results superior to those of traditional manufacturing methods, paying special attention to reducing waste and saving materials, something of special importance in the case of superalloys used in the aeronautical industry. This work reviews the scientific literature published in recent years and studies the development, current presence and projection of hybrid additive and subtractive manufacturing in the aeronautical industry. The processes used, the specific applications, the manufactured parts and the materials used, as well as the advantages and disadvantages compared to other manufacturing processes and the lines of the future both in industry and in the field of research, are addressed.

“…The results showed that the columnar grains, with some fine MC carbide particles in the inter-dendritic zone, formed in the as-deposited samples along the deposited-direction, and the mechanical test data showed that the LMD material had good high-temperature mechanical properties along the longitudinal section. Kapil [7] trialled a hybrid layered manufacturing (HLM) process using metal inert gas (MIG), tungsten inert gas (TIG), and laser cladding (LC) to fabricate turbine blades, and found that this HLM method was 68.29% more efficient than conventional machining processes.…”

Nickel-based K417G superalloy powder is the main material used in laser additive manufacturing (LAM) of aerospace engine turbine blades. In this study, K417G powder was prepared by the vacuum induction melting gas atomisation method (VIGA). Powder characteristics and microstructure were measured, and the properties of fabricated samples were studied. The results show that the powder mean particle size D 50 was 74 μm, flowability was 16.6 s/50 g, apparent density was 4.78 g cm -3 , and the oxygen content of the powder was 0.015%. Powder and LAM sample microstructure consisted of γ, γ ′ , and carbide. The average microhardness was 410 HV, tensile strength was 1080 MPa, yield strength was 828 MPa and elongation was 13.52%. K417G superalloy powder prepared by VIGA method has potential for application in laser additive manufacturing.
