Nexa3D, Ventura, CA, announced commercial availability of its highest throughput additive production system, the QLS 820. With a print speed of up to 8 liters per hour and up to 20 percent packing density, it is designed for high volume production of thermoplastic components. At the core of the QLS 820 is the patented Quantum Laser Sintering (QLS) print engine consisting of four CO2 lasers with a power of 100W each. It features an exchangeable build station that operators can use for continuous production during the cooldown process. It works with standard materials such as PA11 and PA12 — direct replacements for injection molding grade materials — and is also compatible with higher-temperature materials, such as PA6.
