01 High-Efficiency Aluminum Alloy Printing Solution Adapted for Large Formats
Through optimized flow field design and a high-flow circulation filtration system, the BLT-S800 enhances airflow filtration efficiency and reduces printing defects, ensuring more stable quality in full-format forming. Regarding materials, the system utilizes Polymaker’s BLT-AlAM400 aluminum alloy. The deep compatibility between this material and the equipment’s processes allows for high-density metallurgical quality even at a 120μm layer thickness, meeting the dual requirements of efficiency and quality for aluminum alloy mass manufacturing.

02 Synergistic Optimization of 20 Lasers Accelerates Robot R&D and Manufacturing
The BLT-S800 is equipped with 20 lasers and features an optimized high-efficiency printing process, enabling 20 laser beams to operate in zones and achieve efficient stitching on a large 800 mm build platform while effectively avoiding interference. Compared with a 6-laser configuration, the total build time for a full plate is reduced from 119.8 hours to 35.2 hours, and the build time per part is reduced to 58.6 minutes, representing a 70% increase in overall efficiency and achieving a shorter production cycle. This provides a highly efficient, low-cost, high-quality, and stable solution for the mass production of robot components.
