ADMIRE project

Posted on



IREPA LASER is participating in the ADMIRE project to develop a new curriculum, the European Master Degree in Metal Additive Manufacturing (A.M.). The ADMIRE project (knowledge Alliance for Additive Manufacturing between Industry and universities) is a European program, supported by the Erasmus + program of the European Commission. Its goal is to fill the gap in the academical educational system in the field of additive manufacturing. At the same time, it is intended to respond to an urgent industrial need: the qualification of Additive Manufacturing workforce.

This project aims to establish a solid relationship between companies working in the AM supply chain, research centers and universities. Four universities are associated in this project, two in the United Kingdom, one in Germany and one in Portugal. As a recognized expert in additive manufacturing, IREPA LASER is involved in this project for the technological development part.

Laser Direct Metal Deposition processes are applied for the manufacturing of medium to large scale parts in a wide range of materials. With the increase of the size of the part, its distortion along with the robustness of the process during long manufacturing time play a major role. The operating conditions and the construction strategies have to be optimized in order to achieve the expected quality of the part.

Based on additive manufacturing with the LMD process called CLAD® and within the framework of the EU funded FP7 AMAZE project, a large-scale demonstrator (>1m) has been fabricated.

This paper will present the different steps associated with the manufacturing of this part: materials parameter validation, NDTs, mechanical characterization, sub-elements construction and final demonstrator manufacturing. It will also emphasize on the encountered issues during manufacturing and the solutions which have been set-up to fix them.


Fabrication additive : les effets des stratégies de construction sur les pièces

La Fabrication Additive (FA) dont la  Construction laser additive direct (CLAD®) offre la possibilité de fabriquer des pièces métalliques sur mesure, sans outillages et avec des délais de réalisation très courts.

Cependant, la FA étant basée sur un procédé thermique faisant subir au matériau des cycles d’élaboration complets (chauffage-fusion-solidification-refroidissement) les pièces fabriquées avec le procédé FA sont le siège de contraintes résiduelles pouvant entraîner des déformations, des variations dimensionnelles voire des fissurations. Il devient indispensable d’évaluer ou quantifier ces contraintes thermomécaniques afin de pouvoir prédire leurs localisations et les déformations entraînées.

L’étude de ces problématiques, a été menée à travers la modélisation et la simulation numérique, sur les stratégies de construction de plusieurs types de pièces, et trois stratégies différentes de constructions ont été testées. Un montage spécifique a été conçu pour limiter les effets des bridages sur le substrat. Les mesures de température, de distorsions ont été réalisées sur le substrat pendant la fabrication, et les contraintes résiduelles mesurées après construction.

Une comparaison entre modélisation numérique et mesures expérimentales a été faite et sera présentée lors de cet exposé.


Additive manufacturing of functionally graded Ti64-Mo by LMD-CLAD process

The objective of the current work is to manufacture a defect-free functionally graded material (FGM) thin wall structure by the CLAD® process (Construction Laser Additive Direct). FGMs are materials whose chemical composition, and thus mechanical and microstructure characteristics are gradually varied along one or more space directions. Interest of FGMs is thus to associate and concentrate the benefits of two or more materials into one part. The study focused on the transition between layers with a different chemical composition to understand microstructural evolution and evaluating mechanical properties. EDX analysis was performed to control the chemical composition into the deposits and thus validate the response between the programming and the sample. Micro-hardness is used to evaluate the mechanical properties along the wall and thus of the functionally graded Ti-6Al-4V to Mo samples. Microstructure evolution along the wall has been studied under an optical microscope and by the means of EBSD tool which allows to get information about crystallographic texture into the deposition.

5-axis industrial machine

A new 5-axis industrial machine and a femtosecond laser now operational at IREPA LASER. The research and development center specialized in laser applied to materials takes a new step towards the industrialization of laser processes for the industry.

IREPA LASER continues to deploy its Alsace 3D development plan. After the “Metal Additive Laser Manufacturing” (FAML 2020) program, the development center launched ISurf (Intelligent surface functionnalization) and recently equipped itself with a 3D 5-axis texturing machine for finishing operations. IREPA LASER continues to deploy frugal solutions to produce technical parts at a lower cost.

The arrival of this new machine, financed by the State Region Contract Plan, is a real added value for the treatment of surfaces. It allows IREPA LASER to propose to its customers the machining or the fine marking in 3D of metallic or polymer parts, on simple or complex profiles, without discontinuity. The precisions thus obtained are of the order of a micron and can be rendered virtually invisible to the naked eye.

Advantages of the process:

  • 3D machining of complex profiles,
  • Addition of material,
  • All materials,
  • Global or localized 3D treatment.
