Current multi-laser configurations
The current BLT-S400 page lists 2, 3, 4, 6 or 8 lasers at 500 W each. Its 450 × 300 × 400 mm build dimension excludes substrate thickness. Published rates differ by configuration and also depend on part geometry, material and parameter selection.
Powder circulation and monitoring
BLT describes automatic powder recycling, sieving and feeding with a closed circulation system. Fault diagnosis, status tracking, traceability and recoating detection are listed as standard functions; thermal/video monitoring and factory-management integrations are listed separately as options.

The exact BLT-S400 product page was read on 2026-10-16. It specifies 450 × 300 × 400 mm excluding the substrate and lists 2, 3, 4, 6 or 8 lasers at 500 W each. Listed build rates depend on configuration. A first-introduction year is not established by that page.
A larger nominal envelope does not establish better print quality. Fit depends on the configuration, usable area, supports, and orientation.
