Fast-Cycling Selective Laser Sintering System
Nexa3D announced the QLS 260 for metal and polymer production.
Nexa3D announced the QLS 260, a selective laser sintering (SLS) machine, at the Formnext trade show last November in Germany. The QLS 260 builds on Nexa3D’s fast cycle sintering technology, adding a new onboard nitrogen generator for simplified operation. The machine is capable of completing a production cycle in 22 hours and is suited for a wide range of both metal and polymer materials, including the newly available Evonik Infinam TPC 8008 P, a thermoplastic copolyester.

According to Nexa3D, manufacturing from thermoplastic copolyester offers mechanical advantages over thermoplastic polyurethane, including durability, ductility, surface finish and chemical resistance. Thermoplastic copolyester is an elastomer with properties of both polyester and polyether.
Other qualified materials for the QLS 260 include polyamides, PP, PBT and TPU. It can also use recycled waste powders from other printing technologies such as multi jet fusion. The build volume is 9 × 9 × 9.8 inches and laser power is 60 W.
