completed in 2022


European project of the MANUNET network, focused on the research of the additive manufacturing technology WAAM (Wire Arc Additive Manufacturing).

In the first quarter of 2022, this European project of the MANUNET network, dedicated to the research of the WAAM (Wire Arc Additive Manufacturing) additive manufacturing technology and its application to metal components in the aerospace sector, has been formally closed.

The project, led by Aciturri Aeroengines, involved the companies ITRESA (Spain) and ROBCON (Romania) and the technology centers Idonial (Spain) and ISIM (Romania), and addressed WAAM technology from two technological alternatives, TIG and MIG/MAG processes, which have been applied to Ti, Al and Inconel components.

The characterization of the materials in different conditions with both technologies (TIG/MIGA-MAG, with/without laminates, with/without surface treatments) has allowed to obtain decisive conclusions to establish the next steps in the research of applications of this technology in the aerospace sector.


3D printing of new materials and auxetic structures for the improvement of passive combatant protection systems.

Aciturri Additive Manufacturing has been part of the group of organizations, led by the Idonial Foundation, which have developed the IMPACT Project, awarded by the Ministry of Defense of the Government of Spain. The purpose of the project has been the "3D printing of new materials and auxetic structures for the improvement of passive protection systems for combatants", and has been framed in the call for R&D projects of interest for Defense susceptible to be included in the scope of the Program for Cooperation in Scientific Research and Development in Strategic Technologies (Coincident Program).

The project has studied and tested, in conditions comparable to real ones, different auxetic structures made of two materials suitable for defense, manufactured with additive technology. The best performing structures were selected and their ballistic limits were determined under conditions close to those required by the regulations. The project has concluded with the manufacture of two final demonstrators, one in each material studied, and the elaboration of an industrialization plan in which the factors and criteria that will influence a future mass production have been identified, allowing to evaluate, for each material, its potential industrial viability.


Combined tank of cryogenic oxygen and kerosene whose mixture produces the thrust needed to propel space launchers.

CRYOCOMP is a Alestis-Aciturri collaborative develop for a combined cryogenic oxygen and kerosene tank whose mixture produces the thrust needed to propel space launchers.

This project covers the first phase of the complete development of the launcher's second stage tank. During this phase, the tank has been designed and dimensioned and demonstrators have been manufactured to confirm that the highly innovative concepts that had been proposed are viable and meet the requirements of potential customers. The tank is mainly made of carbon fiber by Automatic Fiber Placement (AFP), which allows positioning the ribbons in the most suitable orientations to make the tank highly efficient from a structural point of view, which will ultimately result in a weight reduction that makes it a very competitive product in terms of cost and weight.

The company is an active driver of industrial innovation at the local, regional, national and international scale.
