We present you the Farsoon FS121M metal 3D printing system using selective laser fusion (SLM) technology from the global manufacturer Farsoon (China) with a working area of 120 x 120 x 100 mm.  

Farsoon Technologies is a manufacturer of integrated solutions for industrial additive manufacturing systems by laser sintering of polymer powders and laser fusion of metal powders, founded in 2009 by Dr. Xu Xiaoshu. With over 25 years of experience in the additive industry, Farsoon has built a world-class team of experts with expertise in all areas of electrical engineering, laser sintering, scanning and optical systems, thermal controls, materials development, and application development. .

Features of the FS121M system

The FS121M features a 200W Yb-fiber laser and a fully digital scanning system. These features along with a fine spot size allows for the creation of very detail and complex parts. Farsoon is dedicated to high quality utilizing premium parts for all key components and incorporates the latest safety systems with inert gas supply and over-sized protective filter systems all at a price that is accessible for any business.

Economy and safety

The FS121M is equipped with a brand new state of the art industrial powder handling and loading system. Powder transportation, storage, addition and screening are carried out in an inert atmosphere. The highly efficient inert media filtration system in the FS121M allows the safe use of reactive materials. The high performance of the filtration system and the possibility of automatic cleaning allow it to be used for a long time between filter replacement intervals.

System features

FS421M, like all Farsoon systems, provides users with advanced access to print settings and manage basic printer settings. The open metal 3D printing system provides ample opportunities for the introduction of new materials. In addition, Farsoon's own software has a user-friendly interface both when running on a standalone PC and when using the touch screen.

The software from the hardware manufacturer - a set of BuildStar and MakeStar® software solutions - meets all the requirements of modern software, with the maximum number of settings and functions, while remaining quite easy to use.

open platform

Farsoon is the only laser sintering system producer that allows for complete freedom of operation of its machines. This means that machine parameters and powder choice are unlocked for the user allowing for previously-impossible levels of freedom and flexibility when it comes to MLS production.

Open system settings allow you to adjust the following parameters:

  • Laser power (in the range from 0% to 100% of the rated power). You can set different values ​​for the bottom and top surfaces, as well as the inner padding;
  • The speed of scanning (the movement of the laser beam over the surface of the powder layer), or the transition between sections of the trajectory without fusion;
  • Distance between ray path vectors;
  • Strategy for constructing a trajectory (position and direction of the motion vectors of the laser beam). It is possible to set different strategies for each layer, as well as for different models located on the same platform, for different parts of the same model (contour and infill) and for supports. You can set an arbitrary form of internal filling of models;
  • Parameters for applying a layer of powder (layer thickness, speed of the recoater, movement of the build platform for applying the layer, operation of the powder dispenser mechanism);
  • Beam diameter compensation;
  • Changing the angle of the direction of the scan vectors of even and odd layers;
