Depowdering is a key part of post-processing in metal 3D printing, serving to enhance both product quality and powder recycling efficiency.
Depowdering aims to remove metal powder from the exterior and interior surfaces of the parts after printing, which has a direct bearing on the mechanical properties and surface finish of the product. However, traditional manual depowdering methods have many drawbacks. For large and complex parts, manual depowdering is extremely difficult and prone to damaging precision structures. Additionally, the flying powder not only contaminates the environment and wastes resources but also poses significant safety risks to operators.
To address these challenges, BLT has introduced BLT-QF400 and BLT-QF600 depowdering machines for metal additive manufacturing, aiming to promote the safe and efficient development of the industry through automation and intelligent technologies.
01 Precise Depowdering for Large and Complex Parts
BLT’s depowdering machine is capable of handling large parts with the maximum load size up to 610mm×610mm×710mm (W×D×H) and load capacity up to 800kg, meeting the depowdering requirements of most components on the market. The operating and vibration systems of the machine effectively remove powder that is difficult to access manually through flipping, rotating, and vibrating. In addition, the built-in shock absorption components protect precision structures. With multi-functional air-duster-blow-gun kits, the machine can perform comprehensive depowdering of complex parts, achieving high-quality depowdering results both externally and internally.
02 Multiple Safety and Explosion-proof Guarantees
BLT’s depowdering machine has obtained CE safety certification and ATEX (Explosion Proof) certification, and BLT’s machines and systems have obtained ISO9001、ISO14001、ISO45001 certifications, providing authoritative and comprehensive safety guarantees. BLT’s machines and systems adopt a fully sealed glove box design to realize human-powder isolation throughout the process. They are also equipped with an inert gas protection system that can monitor the oxygen content and pressure inside the box in real-time, minimizing the risk of powder explosion. Additionally, BLT’s depowdering machine utilizes high-quality components, enhancing the stability and reliability, and further ensuring the health and safety of operators.
03 Intelligent, Visual Operating System
The depowdering machine features an intelligent, visual operating system with powerful self-programming and process management capabilities that allows operators to create customized depowdering programs based on part properties, thus enabling personalized operation. The system also supports archiving depowdering processes, allowing operators to view, retrieve, and optimize historical process parameters. This not only optimizes operational efficiency and precisely controls the depowdering quality but also facilitates quality traceability and management of products, ensuring the efficiency and consistency of the overall production.
04 Green and Clean Powder Recycling
BLT’s depowdering machine features a powder recycling system that automatically collects excess powder into the power buckets for further sieving, significantly reducing labor costs and improving powder utilization, whichis of great significance for enterprises to reduce costs and increase efficiency. The system is also equipped with sealed design and inert gas protection to prevent powder leakage and avoid contamination and harm to the working environment and operators. This aligns with the safe and green development trends of modern manufacturing.
05 Compatible with BLT Machines & Systems for Efficient Production
BLT’s depowdering machine is designed to integrate seamlessly with BLT’s printers and powder circulation machines, forming a systematic and professional powder handling solution. Currently, BLT-QF400 is compatible with BLT-A300/A320, BLT-S310/S320, and BLT-S400; while BLT-QF600 supports BLT-S450 and BLT-S600, offering more powerful powder handling capability and depowdering efficiency. Whether it is for small, complex parts or large, industrial components, BLT’s depowdering machine can provide customers with an all-round and efficient depowdering solution.
