Nexa3D, a California-based polymer 3D printing firm, has introduced the pre-launch of its newest 3D printer, the production-ready QLS 350 selective laser sintering (SLS) system. The brand new printer offers a really excessive stage of throughput and adaptability. Moreover, it makes use of exchangeable construct models, enabling operators to proceed printing whereas one batch cools down. Nexa3D is presently in attendance at Formnext 2021.
In response to Nexa3D, the corporate constructed the QLS 350 for max pace and throughput. With half density set to twenty %, the printer can course of eight liters of fabric per hour. That is partly because of its 4 100W CO2 lasers. Manufacturing effectivity is moreover elevated by the exchangeable constructed unit function.
Modular and versatile
“We needed to handle the issues related to conventional SLS methods, comparable to lack of modularity and adaptability,” stated Kuba Graczyk, Nexa3D’s Head of QLS enterprise. “This contains the largest bottleneck brought on by these methods: the necessity to print and funky components in the identical machine. The made-to-measure, exchangeable unit within the QLS 350 removes this bottleneck, enabling producers to proceed operations whereas a component cools — an enormous step ahead for SLS methods.”
Nexa3D is positioning its high-speed machine as a real various to injection molding — the foremost plastic mass manufacturing course of. It’s appropriate for the printing of widespread molding supplies like nylons PA11 and PA12, along with high-temp supplies like PA6.
Efficiency monitoring
Along with its high-throughput-enabling {hardware} options, the QLS 350 comes with software program to enhance effectivity. The software program comes with a KPI dashboard monitor for monitoring machine uptime, construct success price, components printed and different metrics. It is usually designed to work in a cluster with a number of printers and models. Moreover, Nexa3D’s software program operates as a digital twin, enabling operators to assemble data on particular components and observe telemetrics. These telemetrics might embody temperature, scanning pace and laser energy.
“We’ve developed a system that might change how business makes use of additive manufacturing in serial manufacturing,” stated Graczyk. We’ve additionally taken steps to automate the handbook course of of fixing models, for instance by utilizing autonomous guided autos that may transport and dock at every unit to streamline the method.”
In addition to unveiling the QLS 350, Nexa3D has used Formnext to announce different enterprise developments. The corporate has partnered with AI manufacturing software program firm Oqton to include Oqton’s workflow automation instruments into its new dental 3D printing providing. (This contains the NXD 200 dental 3D printer.) Nexa3D has additionally made a number of new appointments. It has employed Nina Swienton as chief advertising officer, Melissa Hanson as vp of product and advertising administration, Dr Mehdi Mojdeh as vp of engineering and Mike Currie as normal supervisor of its desktop enterprise unit.
