Custom 3D printing enclosures for Safran
Client: Safran Group (Safran Aircraft Engines, Safran Aerosystems, Safran Electronics & Defense)
Challenges
Safran has a fleet of machines (FDM, resin, various brands such as Prusa, Formlabs, etc.) spread across multiple sites. The group faced three major challenges
HSE Compliance
The group's strict obligation to eliminate risks related to fumes, nanoparticles, and volatile organic compounds (VOCs) emitted by 3D printing.
Diverse 3D Printer Fleet
The challenge of maintaining a consistent and clean working environment amid a wide variety of printer formats and during laboratory relocations.
Fire Risk
With machines running 24/7, the risk of fire (thermistors, short circuits) on unattended machines at night was a critical concern.
Relocation
The need to regularly move printers between sites or workshops creates challenges in maintaining consistent operating conditions.
Solution
Alveo3D designed and supplied high-performance custom enclosures tailored to the specific needs of Safran's various entities:
1. Advanced Filtration: Integration of HEPA and activated carbon filtration systems to capture 99% of particles and neutralize odors/gases.
2. Automatic Fire Safety: Installation of automatic suppression systems capable of stopping a fire outbreak instantly without human intervention, similar to the protection used in industrial electrical cabinets.
3. Tailor-Made Adaptability : Design of aluminum profile structures that can accommodate large industrial machines while also facilitating transport during departmental relocations.

Results
Working Environment
A uniform environment that facilitates maintenance and compliance with Safran's internal protocols. The enclosures create a clean 'barrier' between the production area and the rest of the office or laboratory.
Maximum Safety
The implementation of Alveo3D enclosures allows Safran operators to run long 3D prints with full confidence 24/7. Fire risk is passively mitigated, meeting the requirements of insurers and the group's HSE management.

Conclusion
The adoption of Alveo3D solutions is not limited to a single industrial player, but addresses a global need shared by many large groups using additive manufacturing.
Faced with common challenges (operational safety, regulatory compliance, production continuity, and equipment standardization), the controlled environments developed by Alveo3D provide a sustainable solution.
