Irepa Laser Technology Transfer Centre

IREPA LASER is an independent Centre of Technology Transfer (CRT), specialised in the field of materials treatment by laser, mainly for micro-machining, laser welding and additive manufacturing. It carries out feasibility studies, develops prototypes, and manufactures industrial pre-series on request. It also provides trainings for the initial and on-going training in laser processes and laser safety. IREPA LASER dedicates a large part of its budget (40%) to the development of new laser techniques/processes. IREPA LASER is member of the MICA CARNOT Institute network, specialized in the field of materials, surfaces and interfaces.

IREPA LASER has devoted more than 10 years of R&D effort to develop an in-house AM solution named DED-CLAD® (Construction Laser Additive Directe), and founded the spin-off BeAM, in charge of the commercialization of the DED-AM machines. DED-CLAD process can find applications between a TRL 2 (like the development of Functional Graded Material: eg: Ti/Inconel) up to a TRL9 for specific repairing applications. And IREPA LASER has developed its own experience in the field of modelling and simulation applied on AM application, based on the use of the GEONX softwares.

IREPA LASER is equipped with the following technological capabilities:

Several Laser Sources (diode lasers and fibre lasers up to 10kW) integrated on various robot and CNC workstations.
