The Nexa3D QLS 820 is an industrial SLS 3D printer aimed at unprecedented production speed, throughput, and flexibility. The noted QLS (Quantum Laser Sintering) technology applies four lasers at once, which takes thermoplastic 3D printing to a whole new level. With full Industry 4.0 capabilities, the machine is designed for consistent and highly economical production compared to traditional tooling costs.

The QLS 820 model is equipped with a spacious build volume, which in combination with a removable build unit and capacity for automation enables smooth 24/7 operation. Due to high temperature support, the machine is able to process a vast variety of materials covering all user’s needs, from general purpose prototyping to industry-specific manufacturing at scale.

The in-house NexaX software encompasses not only smart build preparation functions, but also real-time data monitoring and flexible machine control. In addition, historical data analytics provides enough data to easily keep track of your printer’s performance.

The machine introduces a modular material processing station (MMPS) covering all manufacturing stages, from powder containment and blending to breakout, powder reclamation and sieving, in a completely safe, clean, and efficient way. With an automation-ready structure, scalable system, and advanced fleet management software, the QLS 820 is clearly aimed at massive production.
