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.

The University Hospital of Lille will welcome members of the Radiation Protection Network of Nord-Pas de Calais on October 7, 2016. The program includes conferences on security and radiation protection issues as well as booths managed by professionals from medical, industry, nuclear power and research fields.

During this day, our expert in laser safety and in charge of our training center, Franck RIGOLET, will present the various regulations in terms of laser safety.

About the event:

  • Date: October 7, 2016
  • Topics: Safety and Radiation Protection
  • Location: CHRU Lille – GERNEZ RIEUX Institute, rue du Docteur Schweitzer 59037 LILLE


What is R2Nord network?

The Competent People in Radiation Protection (PCR) and actors of radiation protection don’t feel recognized enough and often run into difficulties because of a constantly changing regulation.

Thus, regional networks were created to organize days of exchanges, to form working groups…

Since 2012, the Nord-Pas-de-Calais has set up its network: the R2Nord, a multisector non-profit organization (health, research, industry…).

Laser Microprocessing Conference – October,19

Microprocessing for Biological Applications Session

Abstract :

« Controlling the wettability of stainless steel by surface texturing using a high power femtosecond fiber laser »

The modification of metallic and non-metallic surfaces properties through laser texturing has been the subject of intense research during the last decade. Under laser irradiation, surface roughness is modified. The increase of roughness is accompanied by a change in the wettability of the surface with no additional coating. The role of different scales of roughness has been largely discussed in the literature. According to Wenzel relation, a surface having hydrophilic property will become more hydrophilic and a hydrophobic surface will exhibit an increase of its original property. However in practice, the situation is somewhat more complicated because wettability is the result of several parameters like surface tension and the exact chemical composition of the surface. The presence of oxygen and carbon atoms plays an essential role and is responsible for the evolution of the surface wettability during a period of about 20 days. The motivation for these studies stems from the interest of having self-cleaning surfaces, antibacterial surfaces for biomedical applications, or anti-icing or anti-corrosive surfaces for aeronautics.

In our study a high mean power diode-pumped Ytterbium fiber laser, integrated in micro-machining platform, has been used to texture stainless steel samples. It produces laser pulses of hundreds of femtoseconds in the near-infrared, with a repetition rate up to 2 MHz and a maximal energy of 150 µJ. Several authors have reported that superhydrophobic effect is obtained by the generation of self-organized micrometric structures. Nevertheless it is possible to improve the process rate by producing structures with designed geometries: the microstructures are thus generated by successive ablations of the material. With appropriate process parameters, it is easy to produce a superimposed self-organized nanostructures, which confers to the surface a dual-scale roughness, responsible for high hydrophobicity, with a contact angle as high as 160°.

By modeling the wetting behavior of a droplet on a microstructured surface by finite elements method, we illustrate the trend for the microstructure to enhance the initial wetting property of the surface. The evolution in time of the surface property after laser irradiation, related to surface chemistry, cannot be avoided but can be accelerated under certain conditions.

The production of a superhydrophobic behavior on non-flat surfaces at a reasonable rate, in conditions compatible with a production environment, remains a challenging issue. We will present a few hints toward such a goal.

Conference « Laser & Medical » – September, 28

During MICRONORA, the Club Laser & Procédés is organizing conferences about the topic: « Lasers in the medical field ». Our expert in micro-applications, Frédéric Mermet, will present the ABLALASE project regarding kidney surgery with lasers.


Lasers have many benefits for partial surgery for kidney cancer, such as the nano-invasive aspect, the ability to incise tissue and cauterize, etc… A bibliographic review regarding laser interaction on biological tissues will be presented during this talk. The research works’ results carried out under this project, where different wavelengths and transmission schemes have been implemented on kidneys, will also be detailed.

About the workshop:

Laser technology is increasingly being used in health and medical equipment fields to treat some diseases or to machine, mark or assemble implant components, prostheses and surgical instruments. Without reviewing exhaustively all laser applications in medicine, this half-day of 10 conferences aims to inform manufacturers on recent developments in this field.
