The project was developed for an international OEM manufacturer specializing in the design of high-performance industrial 3D printers based on powder bed technologies for metals and polymers.
The company integrates dedicated extraction solutions for the cleaning and management of metal powders into its systems, ensuring safe and certified production processes.
Explosion risk
The metal 3D printing process generates highly reactive fine powders such as titanium, aluminum, nickel, and stainless steel. These powders present severe challenges:
- Ignition hazard: high risk of explosion, self-ignition, or self-heating during cleaning.
- Regulations: strict ATEX compliance requirements.
- Reliability: The customer was looking for an alternative that outperformed local products and was more competitive than international players with prohibitive costs.
Inert technology for neutralization
Delfin supplied tailored systems integrated directly into the printing machines:
- MTL 451 BL INERT: Compact single-phase vacuum system for medium-sized printers.
- ZFR 75 INERT: Industrial dust collector for large-sized systems.
INERT technology neutralizes the reactivity of metal powders by collecting them into an oil bath, effectively eliminating the risk of explosion.
- Neutralization efficiency: 95%.
- Wet filtration efficiency: 99.995%.
- Certification: Systems suitable for containing an internal Zone 20.
Safety and performance
- Total protection: safe handling of explosive and reactive metal powders.
- OEM Integration: Compact design perfect for direct integration into 3D printers.
- User Experience: improved user comfort and ease of maintenance.
- Global compliance: full compliance with ATEX regulations and international safety standards.
- Competitiveness: optimal value for money in a market that is highly cost-sensitive yet demands exceptional reliability.
