Bright Laser Technologies (BLT), located in Xi’an, China, has launched a twenty-laser version of its BLT-S800 metal Additive Manufacturing machine. Featuring a build volume of 800 x 800 x 600 mm, the new AM machine is reported to enable shorter part delivery cycle time, resulting in rapid research and production manufacturing.
The BLT-S800 is a Laser Beam Powder Bed Fusion (PBF-LB) AM machine compatible with titanium, aluminium and high-temperature alloys, as well as stainless, high-strength steel and tool steel. Target industries are said to include aviation, aerospace, engine, medical, automotive, electronics, tooling, and research institutes.

“By investing a decade in large format and multi-laser printing, the BLT-S800 has excelled in system stability. Currently, we have deployed dozens of BLT-S800, twenty-laser printers in our customers’ factories, and their reliability and usability have been tested in the market,” stated Eliza Duan, head of International Business Department, BLT.
The BLT-S800 offers a powder circulation system that is reported to safely transfer, recover, sieve, and recycle metal powders on-site. This system simplifies and secures the movement of large volumes of Additive Manufacturing powders from containers to multiple machines, effectively eliminating the risks of spillage, contamination, explosions, or contact with personnel.
Coupled with BLT-BP software, the BLT-S800 also enables streamlined profiling of large-sized parts. This reduces the time spent on profiling and preparation, and reportedly enhances efficiency during the AM process. The software also utilises a dynamic powder laying strategy to adjust the powder fusion speed based on the part contour, allowing for automatic speed adjustments at multiple stages. This approach is said to guarantee both quality and efficiency and, compared to conventional methods, typical parts observe a 30% improvement in single-layer efficiency.
