Affordable, Fast, and Flexible Industrial SLS 3D Printing

Synergy Group 2024

Increase Daily Output with Faster Cycle Times

The QLS 230 delivers a complete print cycle in just 24 hours, with a cooling period of only 2 hours. This significantly reduces downtime compared to traditional SLS printers. Additionally, it utilises a single 30 Watt CO2 laser, eliminating the need for a large and energy-intensive laser system, further contributing to faster throughput.

Synergy Group 2024

Maximize Material Options and Sustainability

The QLS 230 is an open platform, offering compatibility with over 10 qualified nylon and metal fusion materials. This allows you to choose the material that best suits your specific application. Furthermore, the printer excels at working with recycled powders from HP and EOS, promoting operational sustainability.
