3D printing continues to build up momentum with new innovation and new machines. Hunan Farsoon High-Technology Co., Ltd, China announced on May 14th the availability of Farsoon 402 selective laser sintering (SLS) 3D printer, successor model of the established and successful SLS system FARSOON 401. This compact system makes direct use of digital 3D model to produce plastic parts with high surface quality.

Founded in 2009 by Xu Xiao Shu who has more than 20 years of experience in additive manufacturing, Farsoon is now China's biggest and the world's third-largest manufacturer of selective laser sintering machines. The new Farsoon 402 is suitable for production of small series, or protypes / parts with complex geometry.

According to the company, FARSOON 402 has a highest scan speed among all the SLS 3D printers, which has reached to 12.7m/s. The building speed is up to 17mm/hour, more than 60% faster than FARSOON 401.


  • Effective building volume: 400mm x 400mm x 450mm
  • Building speed: 17mm/hour
  • Layer thickness: 0.08mm~0.15mm
  • Laser type: CO2, 100 W
  • Galvo scanning system: dynamic focusing high-accuracy Galvo scanning system (CSI)
  • Laser power control system: Digital signal (high precision and good anti-jamming)
  • Scan speed during building: 12.7m/s
  • Powder feeding mode: Two-way powder feed system with a single feed cartridge
  • Printer size: 2660 x 1600 x 2010 mm
  • Power Supply: 380VAC,50/60Hz,15KVA,3-phase
  • Software: Manual and automatic control mode; Online real-time build parameters modification; Three-dimensional Visualization; Diagnostic function.

Many technical innovations have been integrated in the FARSOON 402 to enhance its performance. The company has invented its own SLS Nylon powder, which has been exported to overseas markets including the US, Sweden and Italy since 2012.

Chinese companies are today no better or worst than western companies, when marketing departments elaborate their lies.

Chinese companies usually mock numbers to make them seem better than they are. I tried industrial machines from china and their results were far worst than they were claimed. So I take this news with a grain of salt.

Scan speed and building speed are linked. For 0.15mm layer height, it has to do 113 layers to build up a height of 17mm. So it did those 113 layers in an hour. That means about 30 seconds per layer. The faster the scan speed, the faster each layer can be put down.

I don't think having the fastest scan speed is going to win any prizes when you have a building speed that's 2.5 million times slower.
