QLS 230

Produce high-performance printed parts with the lowest cost of acquisition.

The Nexa3D QLS 230 uses selective laser sintering (SLS) technology. Various plastic materials can be processed by users to produce intricate shapes and working prototypes.

Selective laser sintering enables the production of 3D printed components with robust and durable mechanical properties. These advantages have also been known for a long time, but until now the production was mostly handed over to third parties because the initial costs for SLS equipment were very high. Thanks to the QLS 230 from Nexa3D®, however, this is a thing of the past!

This SLS system enables functional prototypes and small series of high-quality plastics with terrific properties at an unprecedented price!


Technology: SLS (Selective Laser Sintering)

Build volume: 230 x 230 x 230mm

Laser power: 30W CO2

Max. Build speed: up to 20mm/hour (depending on geometry).


Shorter production times

Print speeds of up to 20 mm per hour are possible with the Nexa3D® QLS 230. This enables faster design review, so that product concepts and ideas can be implemented quickly, which at the same time reduces production costs. For this reason, this printing system is perfect for the production of prototypes of all kinds!

Reasonable laser power and large build volume

With its 30-watt CO² laser and a build volume of 230 x 230 x 230 mm, the QLS 230 offers enough power and space to realize even larger and complex components.

No support material required

SLS technology also makes it possible to manufacture components without additional carrier materials, as the thermoplastic itself serves as the carrier material. This ensures resource-saving production, increased productivity thanks to the possibility of layering many models on top of each other and printing them in any direction, and reduced costs per part.

Good thermal field control and chamber temperature

The Nexa3D® QLS 230 has 2 thermal field controls and its build chamber can reach temperatures of up to 180 °C.

Removable print chamber module

The modular print chamber module of the Nexa3D® QLS 230 enables effective use of the robust system. With the help of the print removal tray, finished prints can be removed from the printer without any problems. This allows you to start the next print immediately without having to finish your parts beforehand. The removable print tray also allows for cleaner and more effective removal of powder.

Cold Metal Fusion Compatible

Cold Metal Fusion from Headmade Materials® is a patented process that combines the advantages of rapid sintering with established powder metallurgy processes for the production of titanium and steel parts. Using a polymer-coated metal powder, the QLS 230 produces greenparts in a low-temperature processing environment. The parts then go through a secondary debinding and sintering process that burns out any residual polymer and sinters the metal particles together to form the final metal components.

Intuitive software

The QLS 230 uses Buildware and Nexa3Dprint, previously known as XYZprint, AM SLS are two user-friendly software programs. Buildware gives the user the ability to start printing directly at the printer. Nexa3Dprint AM SLS also allows users to schedule projects and print jobs, as well as monitor ongoing print jobs.

Open material platform

The QLS 230 has an open material platform, allowing you to find a suitable material for any project.


Industrial manufacturing

End-use printing can even replace injection molded parts, metal replacement parts, components, automotive parts, and more.

Production parts

Produce complex objects quickly and cost-effectively, in small runs or as individual pieces.

End-of-Life HP MJF Powder

HP Multi-Jet Fusion technology limits the recyclability of powder material. Once the limit is reached, the powder is End-of-Life and can no longer be used. This means that HP MJF customers have to dispose of large quantities of powder. Now, this end-of-life powder can be recycled and printed on the Nexa3D® SLS printers. In addition, this powder can be easily mixed with as little as 5% fresh PA12 powder for brighter parts.

Rapid prototyping

Review your design before you go into production. Test form, fit, and function with an accurate representation of the final product.
