On November 10, BLT (688333) was granted a new utility model patent for a powder sweeping device (application number CN202522526911.4). The device consists of a support mechanism, a guide mechanism, and a sweeping mechanism, with the guide mechanism's movement direction non-parallel to the axial direction of the support mechanism, highlighting low retrofit cost and good powder cleaning performance. On the same day, the company also received a utility model patent for an additive manufacturing device. Statistics show that BLT has accumulated 79 new patent grants so far this year, continuously strengthening its patent barrier in additive manufacturing equipment and processes; it has previously filed patents for powder recycling systems and Ti-6Al-4V-0.25Si titanium alloy powder, among others. Leading additive manufacturing companies are accelerating the pace of patent grants, reflecting faster technological iteration on the equipment side. For powder buyers, powder sweeping and cleaning efficiency directly affects powder recovery and utilization rates, and the direction of patent portfolios can serve as a reference for equipment selection and process benchmarking.
