Industrial vacuum systems for 3D printing powder recovery and ATEX risk control
In additive manufacturing, the handling of metal and polymer dust is a critical phase. From dust removal in the print chamber to its reuse, Delfin’s industrial vacuum systems ensure safe recovery of un-sintered powders in inert atmospheres (Argon/Nitrogen) to prevent oxidation. Our technology reduces operator exposure to reactive metal powders and optimizes the efficiency of the entire 3D production flow through ATEX-certified solutions.
Fast and controlled removal of unsintered dust. Our systems reduce downtime and, when handling metal powders, enble extraction in an inert atmosphere to prevent fire and oxidation risks.
Use of Gastight technology in a closed-loop system with inert gases (argon or nitrogen). This approach prevents unexpected reactions, ensuring maximum safety in processes involving fine and reactive metal alloys.
Integrated systems for the separation of contaminants and out-of-specification particles. Sieving stations, including ultrasonic systems, allow efficient material regeneration and improve the quality of the powder reintroduced into the process.
Controlled vacuum handling to prevent dispersion and cross-contamination. We preserve the physico-chemical properties of the powders to ensure consistent and high-quality production.
Pneumatic conveying solutions for safe product transfer to silos, bins, or hoppers. We also operate in inert atmospheres to protect the material from external contamination and oxidation.
Pneumatic conveying systems that feed dosing units directly, reducing manual handling and operator exposure, and ensuring a safe and automated workflow.
