About Farsoon

Farsoon Technologies is one of the largest manufacturers and suppliers of industrial selective laser sintering and metal melting systems, founded in 2009. The founder of the company, Dr. Xu Xiaoshu, has unique experience in the field. He was the CTO of DTM Corporation, now known as 3D Systems, one of the pioneers in the industrial 3D printing market.

Farsoon is constantly engaged in the development and improvement of equipment, with research projects engaging up to 40% of the staff. The company's team of experts specializing in the field of additive and related technologies, including the development of software and materials, allows Farsoon to maintain a leading position in the sector.

Today, the Chinese National Laboratory for Additive Manufacturing operates on the basis of Farsoon facilities, and the United States and European countries are among the main buyers of the company's equipment.


Farsoon metal 3D printing technology

Farsoon industrial metal 3D printers use selective laser fusion technology. The material (a fine dispersed spherical powder made of metal or alloy) is fed layer by layer into the print chamber and onto the base plate. The laser projects a pattern on each layer fusing powder particles together. This technology allows manufacturing parts that are not inferior to casted parts in terms of their mechanical properties. Such parts can also have much more complex shapes compared to casting or milling. As a rule, the printing process is carried out in an inert gas environment, which allows the use of highly reactive materials without oxidation and deterioration of properties.

About the Farsoon metal 3D printing lineup

The current Farsoon metal 3D printing lineup includes six industrial systems and their modifications. The models differ in print chamber size and features. 


Farsoon FS621M

Print chamber: 620 x 620 x 1100 mm

Lasers: 1000W fiber laser or 4 x 500W lasers

With a 620 × 620 mm print chamber base and over a meter in height, the FS621M is one of the largest metal 3D printers in the laser metal fusion equipment market.

Metal 3D printing of products of such scale opens up new opportunities for production. It is used in the aerospace sector, oil and gas and many other industries.

The FS621M comes with one 1000W laser or four 500W lasers for enhanced  productivity. It is an open platform that allows the user to customize print settings and use virtually any metal powder material available. It also has all the main advantages of previous models described below, such as a printed parts handling system, powder sifting module, and an efficient air filtration system.


Farsoon FS721M

Print chamber: 720 × 420 × 420 mm

Lasers: 2×500W or 4×500W

With a print area of ​​720 x 420 x 420 mm, combined with either two or four 500W lasers, the FS721M is able to significantly ramp up productivity in high-volume part production and large-scale 3D printing.

Advanced control software and the Farsoon Precision Scanning System ensure consistent performance across multiple laser overlap areas.

Continuous powder supply, optimized gas flow and a built-in filter module ensure metal powder melting uniformity.

Extended print process controls and real-time monitoring ensure efficiency and high-quality output.

The integrated conveyor system, cleaning station and advanced powder collection system of the FS721M ensure efficient and safe relocation of the collection cylinders (replaceable print chambers) and a completely sealed powder removal process.

Advanced calibration and electrical leveling simplify the workflow. The FS721M is an open platform offering the user the flexibility to customize print settings for industrial applications and cost-effective additive manufacturing.


Farsoon FS421M

Print chamber: 425 x 425 x 420 mm

Lasers: fiber lasers, 2×500W or 1×500W

With a 425 x 425 x 420 mm print chamber, the FS421M metal laser sintering system is capable of producing large metal parts from a wide range of powder materials, metals and alloys.

The large build chamber volume, combined with the multi-laser and all-digital optical system, ensures increased production speeds, while the internal rail system allows for quick swapping of interchangeable print chamber cylinders, allowing continuous production even during cleaning.

The FS421M is equipped with a new advanced industrial powder handling system. Powder feeding, 3D printing and screening are carried out in an inert atmosphere. The powerful and highly efficient air filtration system of the FS421M handles chemically active materials and employs replaceable filters.

Like all Farsoon systems, FS421M gives users complete freedom of action. This means that all the machine’s settings are unlocked for the user, and the system is compatible with third-party materials, not only the ones developed by Farsoon.

Farsoon's proprietary software is easy to use both through an advanced user interface and touch screen based production interface for everyday operation.


Farsoon FS301M

Print chamber: 305 × 305 × 400 mm

Lasers: fiber lasers, 2×500W or 1×500W

The FS301M was highly ranked by a customer from a US-based aircraft company:

“With surface roughnesses of less than 5 µm, exceeding the benchmarks for metal ductility and fatigue tests, the high productivity of the FS301 finally allows cost-effective metal 3D printing without sacrificing part quality.”

Dual laser projection and calibration algorithms increase assembly efficiency due to lasers’ precision control when printing one large part consisting of several small ones. Both lasers can cover the entire print area, and can be used one at a time or for selecting a dedicated laser for a particular object.

Industry-leading signal transition rates and high powder layering speeds ensure minimal delay between coats. The increased volume of the highly productive cylindrical print chamber is 305 x 305 x 400 mm.

With the built-in powder loading dock, the FS301M material feed can be carried out in an inert gas environment, which simplifies the workflow and addresses environmental concerns. A common material container is used during loading, unloading and sifting processes, which provides more convenient powder handling and relocation between stations.

Convenient features such as base plate preheating, electrical leveling and advanced vision systems ensure process stability and quality control.

The FS301M unit occupies an area of ​​only 3.64 square meters. The filtration system can operate for up to 1,500 hours without maintenance. The settings allow to create high-density layouts with minimal lateral spacing for maximum productivity.
