Navigat’s independently developed 3D printing additive recycling system achieves efficient and safe screening and recovery of metal powders through fully enclosed inert gas protection, addressing the long-standing industry challenges of material oxidation and contamination.
In the cutting-edge field of metal powder 3D printing, powder recycling has always been a key bottleneck restricting cost reduction and quality improvement in the industry. Shanghai Navigat Screening Technology Co., Ltd. has developed the 3D printing additive recycling system, equipped with patented technology that fills a gap in the market, providing a disruptive solution for the safe recycling and efficient reuse of metal powders.
01
Challenges in Metal 3D Printing Powder Management
As the core material for 3D printing, metal powders face two major challenges in actual production:
-
Powder contamination issue: During laser forming, metal condensates are produced, which mix with unused powders, directly leading to a decrease in powder purity. Continued use can severely affect the precision of printed parts and even result in product scrapping.
-
Oxidation waste issue: Reactive metal powders such as aluminum and titanium, as well as fine particles, are prone to oxidation in exposed environments, making them non-reusable and potentially creating safety hazards due to the accumulation of oxidized powders, resulting in significant material waste.
02
Navigat’s Patented Solution
The NMS system achieves efficient and safe recovery through the following methods:
-
Real-time suction screening: Metal powders and condensates that escape during the printing process are continuously sucked into the screening equipment.
-
Inert gas closed-loop: The entire screening and recovery process is conducted in a closed inert atmosphere, ensuring a low-oxygen environment that effectively prevents the oxidation of fine powders.
-
Pure powder reuse: The separated metal powders are directly fed into the powder feeder for recycling back into the printing system for reuse.
03Empowering the 3D Printing Industry
The design of the NMS series systems fully reflects cutting-edge demands and possesses the following significant advantages:
-
Fully enclosed inert gas protection: Ensures low-oxygen explosion-proof operation, safeguarding both operation and equipment safety.
-
Large particle separation function: Effectively filters out metal condensates, providing a safer and more stable operational foundation for printing equipment.
-
Continuous recovery without interruption: Automated separation and replenishment without human intervention, maintaining printing continuity.
-
Automatic refilling mechanism: Reduces operational risks and avoids human contact with fine powders, enhancing safety.
-
Efficient material-saving effect: Achieves the recycling of metal powders, reducing material waste and enhancing economic benefits.
-
Simplified disassembly and maintenance: Reduces downtime and facilitates daily operations.
-
No fine powder escape, low noise operation: The system operates in a closed manner, being environmentally friendly and quiet.
The NMS series 3D printing additive recycling system is a safe, efficient, and material-saving solution for the metal powder 3D printing industry to achieve additive recycling. It integrates four major advantages: manufacturing continuity, safety protection, material reuse, and easy maintenance management, helping laboratories and production lines enhance additive utilization efficiency and printing stability.
