In the mass production of metal additive manufacturing, powder recycling is crucial for controlling costs and ensuring safety. Bright Laser Technologies (BLT) has developed a metal powder recycling system to improve powder utilization and promote safer, more environmentally friendly, and efficient industry practices.
The material machine uses vacuum pressure to transport powdered materials from the build chamber or transfer station to the sieving machine for processing. BLT’s powder recycling systems offers advantages in safety, efficiency, durability, intelligence, and convenience compared to alternatives.
01 Human-Powder Isolation Design
The system achieves human-powder isolation in the whole process, preventing direct contact between metal powder and operators. This reduces safety hazards and occupational health risks. An inert gas protection device prevents powder oxidation and contamination, ensuring recovered powder meets standards for reuse. This design aligns with modern industrial requirements for environmental protection and sustainable development.
02 One-Touch Intelligent Operation
BLT’s system features an advanced intelligent control system for automated operation in the whole process. Powder extraction, transportation, and recycling can be done in one-touch without manual intervention. Operators only need to perform initial settings, after which the powder is quickly and evenly transported to the designated position, eliminating manual handling risks.
03 Highly Vacuum and Redundant Oxygen Sensor Design for Safety
The highly vacuum environment effectively captures unsintered powder and assists in chamber cleaning, significantly reducing powder waste. A sealed chamber design isolates external contaminants, enhancing recovered powder quality. The built-in oxygen sensor works with the main printing machine to implement safety interlocks, ensuring operational and recycling safety.
04 Multiple Compatible Models
The lightweight, modular design allows for quick installation and flexible configuration. A mobile extra-large powder bin is compatible with various models. Two models are available:
- BLT-WL200: Recommended for BLT-A300/A320, BLT-S400, BLT-S450
- BLT-WL400: Recommended for BLT-S600/S615 series, BLT-S800/S815 series, BLT-S1000, BLT-S1300, and BLT-S1500
BLT also provides overflow powder recycling modules withing the printing machine and whole-machine powder circulation system for comprehensive powder handling, aiming to create a closed-loop powder processing system.
Efficient metal powder recycling is essential for sustainable development. BLT actively supports the manufacturing industry’s environmentally friendly advancement with continuous innovation.
