Key Features of SLS 3D Printer 650

Wind Field and Wind Knife Finite Element Simulation

Utilizes advanced finite element analysis of airflow fields and air knives to deliver precise theoretical support and practical guidance, optimizing stable and uniform wind field design for consistent high-quality sintering.

Multi-Mirror (Galvo) Control

Supports simultaneous operation of 1–8 high-speed galvo mirror units, providing flexible adaptation to various forming areas and build volumes for maximum production versatility.

Independent Slicing Engine

Offers a proprietary, standalone slicing engine that significantly reduces dependency on expensive third-party software, lowering overall operational and development costs.

Multi-Laser Intelligent Stitching and Task Allocation Algorithms

Employs dynamic random partitioning, regional contour offset overlay, and seamless interval stitching with intelligent task allocation to achieve flawless, large-area multi-laser prints without visible seams.

Multi-Beam Intelligent Anti-Collision Control

Intelligently divides and plans multiple laser paths in real time to prevent collisions, simplifying optical system design and ensuring safe, efficient multi-beam operation.

Beam Shaping

Features advanced variable spot control with ring, flat-top, and Gaussian beam profiles, supported by dynamic response algorithms for enhanced precision, energy distribution, and process flexibility.

Spot Tracking

Implements real-time spot tracking technology, allowing simultaneous powder spreading and laser processing (edge laying and printing), dramatically improving overall printing efficiency and throughput.

Parametric Process Packages

Enables low-cost, autonomous, and rapid development of customized process parameter sets, supporting the establishment of an independent technical database for continuous material and process optimization.
