Nexa3D QLS236 3D Printer


QLS 236 is an open platform selective laser sintering (SLS) 3D printer with an unrivaled 21 hour cycle speed. It uses a single 60 Watt CO2 laser to produce prototypes and production parts with robust mechanical and thermal properties. In addition to a broad range of high-temp thermoplastic materials, it excels with recycled powders from HP® and EOS.

Increase Daily Output

With industry-leading cycle time of just 21 hours where the required cooling period is only 2 hours, the QLS 236 is a productivity powerhouse. It uses a single 60 Watt CO2 laser to increase your daily throughput without the need for a lengthy cooling period due to its smaller build chamber.

Material Flexibility

The QLS 236 is an open platform with 16+ qualified materials including a range of Polyamides, PP, PBT, TPU, as well as the patented metal powders from headmade materials®. In addition to the currently qualified materials, it excels with recycled powders from HP and EOS to extend the life of your powders and provide operational sustainability.

Lowest Total Cost of Ownership

With one of the lowest entry points in the professional selective laser sintering market, combined with lower operating costs due to its powder refresh rate of just 20% and use of third party materials, the QLS 236 offers the lowest total cost of ownership for your industrial SLS 3D printing needs.

Open Material Platform

Your production capabilities with the QLS 236 are nearly limitless thanks to its open material platform, wide-use temperature range, and inert processing atmosphere. From common filled and unfilled nylons to rugged polymers like PBT, the QLS 236 is compatible with a versatile range of materials to ensure that you’ll have the right material for the job.

Intuitive Software

QLS 236 is powered by two advanced software suites, Buildware and XYZprint AMSLS. Buildware controls the sintering process while the XYZprint AMSLS allows users to start and monitor jobs remotely.


Cold Metal Fusion Compatible

Cold Metal Fusion by headmade materials® is a patented process that combines the advantages of fast cycle sintering with established powder metallurgy processes to create titanium and steel parts. Using a polymer-coated metal powder, the QLS 236 produces ‘green’ parts in a low temperature processing environment. Parts then go through a debinding and sintering process that burns out any remaining polymer and sinters metal particles together to form final metal components.
