SLS Aero Project

The general goal of the project is to undertake the necessary research for the definitive and industrial application of additive manufacturing (AM) technology in the aeronautics industry, allowing the mass production of flight parts and tooling, which is to say, to increase the TRL of metallic additive manufacturing technology in the aeronautics market.

The following specific technical objectives have been proposed to achieve this:

- Determine the current capacity of AM technology using laser sintering to address the high-level requirements of the aeronautics industry.
- Increase knowledge of the influence of the principal variables of the laser sintering process on the final quality of parts (structural performance, metrology, etc.).
- Determine the possibility of maintaining the capacity for homogenization, repetition, and reuse of the material from AM technology, while still responding to the industry's requirements.
- Determine the current capacity of AM technology using post-processing to address the high-level requirements of the aeronautics industry.
- Increase knowledge of the influence of the principal variables of the post-processing processes on the final quality of parts.
- Validate findings by manufacturing tests of prototypes on a laboratory scale to demonstrate the capabilities and real needs of the complete technology (laser sintering + post-processing).
- Determine the most suitable process conditions that will make it possible to certify additive manufacturing processes for obtaining aeronautical components in the future.


Degree of homogeneity, repeatability and reuse of ALM technology materials applied to aeronautical sector requirements.

In order to study the repeatability of the process along with its quality, different experiments have been made that have allowed to analyze both mechanical properties and tolerance. Results indicate that the process is repeatable and that no significant differences are identified between the different working areas in the work platform of the SLS equipment.

Identification of the variables of operation of the laser sintering process more adequate to respond to the needs of the aeronautical sector.

We worked on the design, development and manufacture of test pieces, ad hoc parts and demonstrators. During the processes, we have evaluated the manufacturing strategies and machine parameters most appropriate to get the best results both from the dimensional and physical-mechanical point of view of each element. This experience has served to establish the most appropriate manufacturing methodologies to build right parts, guarantee repeatability of the process and its homogeneity.

Finishes and dimensional tolerance.

High requirements required in finishing and dimensional tolerance are characteristic of the manufacturing processes of the aeronautical sector. Inside this framework, analyzes, experiments and studies related to different technologies have been made, complementing the SLS, allowing to improve surface finish and achieve the required dimensional tolerance.

Identification of suitable materials for the aeronautical sector within the families of metal alloys previously identified as more appropriate.

Inside of aeronautics requirements, the metallic materials used are characterized by providing adequate mechanical properties with the smallest weight as possible. In this case, one of the materials most used is a titanium alloy (Ti6Al4V), which brings lightness at the same time as resistance. The studies made in the SLSAero project have focused on the analysis of this material and the results have been positive. Titanium alloys processed by SLS have high capacities for the aeronautical sector.

COROMA PROJECT (Cognitively Enhaced Robot For Flexible Manufacturing of Metal and Composite Parts)

To progress in the scientific and technological development of robotics is one of the pillars of Industry 4.0 and constitutes one of the priority action axes marked by the European Commission to boost the competitiveness of the industrial sector in Europe.

The European project COROMA, an initiative coordinated by the technology centre IK4-IDEKO and in which Aciturri participates as final user of the advancements, is developed in this context. It seeks to develop a new concept of intelligent, modular and flexible industrial robots, with the capacity to execute multiple processes and to manufacture metallic and composites detail parts for sectors as demanding as aeronautics.

The robotic system will be able to perform drilling, trimming, deburring, polishing, sanding, non-destructive inspection and adaptive fixation. Using a simple interface, it will receive basic commands that will require minimal programming effort from the operator. In addition, it will move autonomously in the production plant, perceiving the manufacturing environment and locating the elements to be manipulated, even using the required tools for the processing of the pieces.

IMPACT Project - lighter protection systems for Defense through 3D printing

The IMPACT project is aimed at the "3D printing of new auxetic materials and structures for the improvement of passive protection systems for combatants" and is part of the R&D projects of interest for Defense included in the scope of the Program for Cooperation in Scientific Research and Development in Strategic Technologies (Coincident Program).
The fundamental concept of IMPACT is the design, development, fabrication and validation of reticular structures with auxetic properties. Auxetic structures and materials are those that have a negative Poisson's coefficient, which means that their behavior is the opposite of that usually expected when subjected to tensile/compression processes: when subjected to traction [compression] in the axial direction, an expansion [compression] is produced in the transverse direction. This characteristic makes the combination of these materials and structures ideal for protection systems and, as on other occasions, opens up a wide range of opportunities for their application in other sectors by combining lightness and strength in structures that until now had to be solid.
The scope of the project includes the validation of test specimens in different commercial materials, and also includes the specific development of a steel with ballistic quality, atomizable and processable through 3D printing technologies.
The project, sponsored and supervised by the General Directorate of Armament and Material of the Ministry of Defense of the Spanish Government, is led by Fundación Idonial and, together with Aciturri Additive Manufacturing SLU, ArcelorMittal Innovación Investigación e Inversión, SL and Fundación CIDETEC are participating in its development.
