QLS 236

Fast Cycle SLS 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.

QLS 236 Fast Cycle SLS 3D Printer

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.
