Ideal Use: Laser Sintering 3D Printer for High Throughput Production. Up to 8L per hour, 20% packing density. View full description


With the highest part throughput in its class, the QLS 820 thermoplastic 3D printer is a quad laser system which offers unprecedented production capabilities designed with automation and scalability in mind. The QLS 820 takes 3D printing to a whole new level, producing up to 4x the throughput of traditional laser sintering 3D printers and other polymer powder bed technologies.

Industry’s Fastest SLS 3D Printer

The QLS 820 has smart automation, removing pain points in capacity utilization and downstream labor intensity. With 4x more power and throughput compared to competitor models, this thermoplastic 3D printer can print up to 8 liters per hour at 20% job density.

Broad Material Selection

A wide-use temperature range, inert processing atmosphere, and an open source platform allow for the printing of many materials including PA12, PA11, Polypropylene, as well as aluminum, glass and fiber-filled options.

Scalable Convenience

With an automation-ready architecture, modular material processing system, and advanced fleet management software, the QLS 820 is designed to be scaled for production.
