QLS 230

Fast Cycle SLS 3D Printer

QLS 230 is the most affordable open platform selective laser sintering (SLS) 3D printer for industrial use. It provides a 24 hour cycle speed using a single 30 Watt CO2 laser to produce prototypes 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.

QLS 230 SLS Laser Sintering 3D Printer

Increase Daily Output

With a cycle time of just 24 hours where the required cooling period is only 2 hours, the QLS 230 is a productivity powerhouse. It uses a single 30 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 230 is an open platform with 10+ qualified nylon and metal fusion materials. In addition to the currently qualified materials, it excels with recycled powders from HP and EOS for ultimate operational sustainability.

Lowest Total Cost of Ownership

With the lowest entry point 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 230 offers the lowest total cost of ownership for your industrial SLS 3D printing needs.

PepsiCo Logo

“Our QLS 230 SLS printers offer something others do not, the ability to use end-of-life powder from our EOS and HP MJF machines for high-quality SLS parts. On top of the operational sustainability, the smaller build volume of the QLS 230 allows for a 22 hour complete build cycle that only requires a 2 hour cooling cycle with zero negative effect on part accuracy or surface quality.

The adoption of the smaller platform for high daily throughput is a game changer. We have options for an expedited two business day turn-around in our 3D Printing Service.”
