Additive manufacturing specialists offer manufacturers modular micro-factories to support their demand for flexibility and allow them connected and distributed production, as close as possible to uses.

More flexible production, carried out as close as possible to the place of use. This grail of additive manufacturing, hoped for since the arrival of this technology in production, is getting closer and closer to concrete applications. It is now driven by two concepts that could reshape the industrial landscape: micro-factories and distributed production.

With the increasing digitization of factories, manufacturers want to implement set up small production units connected and adapted to local needs. These islands of machines would be driven by factory data, stored in the cloud, ensuring the repeatability of the process. This concept has taken its mark in the offer of machine manufacturers and software developers dedicated to additive manufacturing.

“The idea of ​​a micro-factory, still exotic a few years ago, has taken hold, explains Jean-Daniel Penot, head of the research and innovation department at the Campus for higher education and vocational training (Cesi) and vice-president of the France Additive association. Atoday, the main processes having passed the milestone of industrialization, such as fusion laser, cold spray (cold spraying), binder jetting (binder jetting) or even the arc-wire process (Waam), are developed in micro-factories to facilitate the deployment of production units as close as possible to needs .

Handddle’s Smart Farm

The micro-factory offers the industrialist an environment encompassing many stages of production. Often placed in containers to facilitate their transport, these devices allow the installation of various sensors for better monitoring of production.

The start-up Handddle presented the second prototype of its Smart Farm at Formnext 2021, which took place from November 16 to 19. This concept brings together in a compact environment the printing unit, material management and a post-processing system. It rests on

New research reveals clues to how antibodies become fine-tuned to fight infection

Graphical abstract. Credit: Cell Reports (2022). DOI: 10.1016/j.celrep.2022.110512 Researchers at the University of Alberta have uncovered new information about a cellular mechanism in the immune system that provides a critical step toward better understanding how antibodies evolve and improve in the human body. The antibodies our immune system produces need fine-tuning to reach maximum effectiveness.…

Could Fungi Actually Cause a Zombie Apocalypse?

Zombies strike fear into our hearts – and if they’re persistent, eventually, they get inside our heads. Animals taken over by zombies no longer control their own bodies or behaviors. Instead, they serve the interests of a master, whether it’s a virus, fungus or some other harmful agent.The term “zombi” comes from Vodou, a religion

Lessons from Colorado fire: Climate change and new buildings

Superior, Colorado The winter grassland fire that blew up along Colorado’s Front Range was rare, environmental scientists say, but similar events may be more common in the coming years as climate change dries grasslands and suburbs grow in fire-prone areas and people continue to spark destructive blazes.“These fires are different from most of the fires…

California fights fire with fire to protect giant sequoias

Flames got close to the General Sherman, the world's biggest tree, but were pushed back thanks to years of controlled burns that starved the fire of fuel. The so-far successful battle this month in California to save the world's biggest trees from ever-worsening forest blazes seems to offer an important lesson: You can fight fire…
