“Industrialization: how to gain industrial agility and bring continuous improvement to production?” This was the question asked this October 11 during a round table moderated by Bakhta Jomni, deputy editor-in-chief of Plastiques & Caoutchoucs Magazine, as part of the 3D Print Paris trade show.
Participants included: Anthony Seddikki, founder of Cosmyx 3D, Jacques Doumeizel, commercial director of MicroplastEmilien Goetz, pre-sales consultant at Siemens Digital Industries SoftwareGuillaume de Calan co-founder and CEO of Nanoe and Kévin Manchon, director of 3D Solutions.

Between prototyping, tool manufacturing and small series, 3D printing has been taking small steps in recent years in many industrial sectors: from medical and paramedical to mobility in the broad sense, including energy and defense. Its advantages ? Foolproof responsiveness with the possibility of manufacturing on demand and as close as possible to the customer (distributed manufacturing dear to Anthony Seddikki of Cosmyx), the resulting reduction in stocks, massive customization, the possibility of producing complex parts , a small footprint or its certain complementarity with plastic injection.
Agility and speed
“We produce process parts for the automotive sector, for example to hold openings during the cataphoresis or painting phases. Thanks to the rapid prototyping that additive manufacturing allows, we can, following validation, have the molds manufactured and then inject several hundred thousand parts,” illustrates Jacques Doumeizel at Microplast. In September 2022, the plastics manufacturer acquired a networked fleet of around forty Cosmyx 3D machines, allowing it to respond with agility and speed to customer requests in terms of production or even to manufacture gripping hands or other tools necessary for the injection process. “We have thus gained speed during the ramp-up phases, particularly in designing perfectly adjusted tools,” says the sales director.
“ By 3D printing its train panels, Siemens Mobility can continuously improve their design. And today, post-processing makes it possible to obtain parts with a final quality equivalent to injection,” indicates Emilien Goetz.
Growing competence
However, the need for specific skills and training still constitutes an obstacle to the development of 3D printing in the industry. “We collectively need increased skills in 3D design. Professionals in design offices are more used to drawing to meet the constraints of machining or molding, not for wire deposition or FDM. We are currently carrying out discussions with the Campus of Aeronautical and Space Professions and Qualifications (CMQ) in Ivry to set up a trainer training project,” indicates Anthony Seddikki. “Most of the training is done internally. We had the effective support of Cosmyx 3D on this subject,” adds Jacques Doumeizel. “Mastering CAD and 3D tools is a minimum. Then, each machine and each technology is different, so it is up to manufacturers and/or distributors to train users,” explains Kévin Manchon, director of 3D Solutions.
“There are many training courses for engineers or technicians that include modules on additive manufacturing,” says Guillaume de Calan, CEO of Nanoe, who concludes his remarks with an anecdote: “I have seen several projects come to fruition thanks to insistence of the latest recruit, a young person who has a 3D printer at home for example, who suggests to his manager the idea of using additive manufacturing rather than another technology”.
A development which is also reflected in the aisles of the show. “on our stand, the questions are now much more precise than before. We are faced with real use cases that are increasingly interesting to carry,” notes Anthony Seddikki. The multiple collaborations between players in the sector are another positive sign. “This shows that additive manufacturing is really getting closer to the industrial world in terms of maturity and skills,” insists the president of Cosmyx 3D and the association Solidarity visors born at the start of the 2020 health crisis.
