High quality 3D printers
Fast Cycle SLS 3D Printer
With an unparalleled 21-hour cycle speed, the QLS 260 is an open platform selective laser sintering (SLS) 3D printer. It creates production parts and prototypes with strong mechanical and thermal qualities using a single 60 Watt CO2 laser.

The QLS 260 is an industry-leading productivity machine with an industry-leading cycle time of just 21 hours and a 2-hour cooling period. Because of its smaller build chamber, it can enhance your daily throughput with a single 60 Watt CO2 laser without requiring a long cooling interval. It works well with a variety of high-temperature thermoplastic and metal materials, but it also performs exceptionally well with recycled waste powder from other technologies, such as multijet fusion.
The QLS 260 delivers the lowest total cost of ownership for your industrial SLS 3D printing needs because it has one of the lowest entry points in the industry for selective laser sintering, along with lower operating expenses because of its 20% powder refresh rate and usage of third-party materials.

Advantages
Fast SLS 3D printing
With an industry-leading 21-hour cycle time and an upgraded printing speed of up to 22 mm per hour, the QLS 260 is a productivity powerhouse that provides the high-quality parts you require.
Shorter production times
In addition to the higher printing speed, the QLS 260 also has a shorter cooling time of only two hours compared to other SLS machines. This ensures higher throughput without compromising quality or the mechanical properties.
More powerful laser and larger build volume than the QLS
230
The QLS 260 is equipped with a 60-watt CO² laser compared to the QLS 230 that has a 30-watt CO² laser. With a more powerful laser, attain twice the printing speed.
The QLS 260 has a build volume of 230 x 230 x 250 mm while the QLS 230 has a 230 x 230 x 230 mm build volume. With a larger build volume, larger projects are now possible without difficulty.
On-board Nitrogen Generator
Compared to the QLS 230 and QLS 236 the QLS 260 has a built in Nitrogen Generator that enables it to have a smaller footprint. The nitrogen generator displaces the oxygen, which helps avoid undesirable chemical reactions and thermal deformations. With the help of a nitrogen generator for SLS 3D printing, you can eliminate oxygen and improve the quality of your 3D-printed products.
No support material required
When using SLS technology, it is not necessary to print additional support structures to hold the component in position during the printing process, as the thermoplastic automatically also serves as a support material. As a result, the printing process conserves resources and the print result is not compromised. Furthermore, multiple models can be stacked and printed in any orientation, increasing productivity and reducing part costs.
Powerful temperature control
The Nexa3D QLS 260 has 6 thermal panels and its build chamber can reach temperatures of up to 220 degrees Celsius.
Removable pressure chamber module and recycle bin
The modular print chamber module of the Nexa3D QLS 260 enables effective use. You can remove the finished print job from the printer and let it cool down in the postpress station. The removable recycling container also makes it easier to reuse the 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 260 produces "green" parts 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.
Open platform that uses excellent functional materials
With proven processes for PA12s, PA11s, PA6s, TPU 88, INFINAM® TPC, PBT, and several Headmade Materials® metal feedstocks, such as titanium, stainless steel 316L, SS 17-4, and M2 tool steel, among many others, the QLS 260 has an open platform.
Intuitive software
NexaX for QLS, a robust yet user-friendly platform for configuring builds and managing the sintering process, powers the QLS 260. Users of NexaX for QLS can also remotely schedule sintering jobs and verify print files. NexaX is the combination of Nexa3D Buildware and Nexa3D Nexa3Dprint AM SLS.
Applications
Industrial manufacturing
Series components that can even replace injection molded parts.
Production parts
Produce complex objects quickly and cost-effectively.
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 HP MJF customers must dispose of large quantities of powder. Now, this end-of-life powder can be recycled and printed on Nexa3D® SLS printers. In addition, this powder can be easily mixed with as little as 5% fresh PA12 powder for brighter parts.
Rapid prototyping
Test form, fit, and function with an accurate representation of the final product.
