Nexa3D’s New QLS 350 SLS System to Allow users bring 3D printing to Production Floor At Scale

0 15

Nexa3D, Producers of Ultrafast polymer 3D printers, today opened up on its prelaunch of

its QLS 350 selective laser sintering system (SLS) system.
The QLS 350 Thermoplastic 3D printer makes good on its promise of significant cost reduction when compared to conventional methods and delivers unique production throughput and flexibility.
allowing users to bring 3D printing to the production floor at scale.

the QLS 350 SLS system by Nex3D is designed to be all about throughput and speed, attaining a speed of 8 litres per hour at 20% job density-
The highest throughput in its class.
The QLS 350’s unique light engine consists of 4 CO2 lasers with 100W power each, users can attain close to 4 times the print speed of conventional laser sintering processes.

taking thermoplastic 3D printing to a never before seen level.
The QLS 350 also has exchangeable build units users can use to continue manufacturing

while precious components cool off inside the exchangeable build unit,

allowing users the speed needed for manufacturing.

QLS 350 SLS System

The QLS 350 system provides a polymer-based manufacturing option for regular injection moulding,
The platform is adaptable with standard materials such as PA11 and PA12-

Direct alternatives for injection moulding grade materials and is also suitable

with higher temperature materials like the PA6, at processing temperatures of up to 240 degrees Celcius.
The QLS 350’s software features a KPI dashboard monitor allowing users to measure what matters to them,

for example, build success rate, machine uptime and a number of components printed.
The software is developed to work in tandem

with multiple units and printers

. so users can enhance productivity with many units for an integrated operation and easily monitor the work of each machine.

Eliminating Conventional SLS System Challenges

According to Kuba Graczyk,

the Head of the QLS business at Nex3D “

we wanted to confront the hurdles common with conventional SLS systems, such as lack of flexibility and modularity.

This includes the largest bottlenecks caused by these systems_ the need to print and cool the same parts in the same machine.


The multi-functional QLS 350 eliminated this bottleneck by allowing producers to progress with operations while a part cools, this is a big step for SLS systems.”

Instant access to data is more and more becoming more crucial to 3D printing. Through using software working a digital twin, operators can monitor telemetrics from the build jobs,

such as scanning speed, temperature, the power of the laser, as well trace previous data down to a specific component.


production floor overseers can carry out one-click reporting to access machine performance and can custom make reports to communicate

build performance and quality to clients.
Graczykfurther added,

” 3D printing is still relatively new to the production floor, meaning clients are, more than often concerned that the equipment will not provide consistent quality-

This is now a thing of the past. The QLS 350 is easy for users to operate consistently

while taking advantage of software that delivers real-time data on the parameters influencing part quality.


“We have designed a system that would revolutionize how the industry

sees 3D printing in serial production, we have also taken steps to automate the manual process of switching units,
An example is using autonomous guided vehicles that can transport and dock at each unit to streamline the process,” Further added Graczyk.
