Protectiv

ProtectivProtectiv, our subsidiary brand, manufactures sustainable protective equipment that is 100% made in France. It is made from plant-based materials that care for the environment. Breathing masks, plexiglass screens, hands-free door openers, protective visors and more. Everything you need to protect yourself and others!

The brand genesis took place during the Covid-19 crisis, as a way of participating in the national effort. It was the "Visors of Hope" operation that prompted Demgy to manufacture visors using 3D additive manufacturing and to donate them to nursing staff.

No more disposable equipment: with Protectiv, masks are reusable and sometimes even dishwasher safe. Break free of the surgical masks that litter the streets, choose non-polluting protection, made with respect for the nature we care about!

Atelier 3D

Atelier 3DAtelier 3D (the 3D workshop) is an industrial revolution in its own right. What’s the concept? 3D printing all your parts, saving you time and money. Our HP Jet Fusion 4200 machine uses polyamide 11 Rilsan®, a natural material made by Arkema from castor oil. Demgy also has an EOS P 810 laser sintering machine for EOS HT-23 material.

This material produces lightweight and highly impact-resistant parts. Their properties in terms of ductility and elasticity are far superior to those of polyamide 12.

3D additive manufacturing makes it easy to produce prototypes of all kinds to the most complex designs. Give way to your wildest ideas: Atelier 3D makes them come true! Above all, 3D additive manufacturing allows you to produce your parts very quickly, at a much lower cost than traditional manufacturing methods, regardless of the number of units to be produced.
