How much does the Farsoon FS1521M cost?

Price estimate

Uncertain

We do not have a price for the Farsoon FS1521M that we can stand behind, so we show no number. Configuration, options and installation move the final price a long way: a quote is the reliable figure.

Overview

The Farsoon FS1521M is a laser metal additive manufacturing system built around a build cylinder more than a metre and a half across: the effective build size is 1510×1510×1650 mm on the square cylinder, the machine weighs approx. 65000 KG, and it carries either 16 or 32 fiber lasers of 500W each.

Farsoon lists two configurations. The FS1521M-U-16 has 16×500W lasers and appears with a circular cylinder (Φ1530×1650mm, effective Φ1510×1650mm) or a square one (1530×1530×1650mm, effective 1510×1510×1650mm). The FS1521M-U-32 has 32×500W lasers and is listed with the square cylinder only. The shape matters for the kind of part. A circular cylinder suits rings, casings and other round sections and takes less material to fill, while the square cylinder gives the corners back for rectangular parts or nested batches.

Every other process figure is shared. Layer thickness is 0.02~0.1 mm, scanning speed is max. 10 m/s through F theta lenses, and the chamber runs under argon or nitrogen at 35 - 40 L / min. With 1650 mm of build height and layers no thicker than 0.1 mm, a full-height job is a very long build, which is why the laser count is the figure to study: going from 16 to 32 lasers puts twice as many beams on each layer.

Installation is a building project rather than a delivery. External dimensions are 13750×6530×6950mm, so the hall needs far more clear height than a normal machine shop bay, and the floor has to carry approx. 65000 KG before any material is loaded. Power for Europe and China is 400V±10%, 3~/N/PE, 50Hz at 125A/160A; the table does not say which current belongs to which laser count. For the US, a transformer is sold with the machine. The room has to be held at 22-28°C.

Listed materials are TA15, IN718, IN625, AlSi10Mg and 316L, with Ti6Al4V and GH4099 marked by an asterisk that the table does not explain. Software is BuildStar and MakeStar on 64 bit Windows 10.

Strengths & Limitations

Strengths

Effective build size of 1510×1510×1650 mm on the square cylinder, or Φ1510×1650mm on the circular cylinder of the FS1521M-U-16
Choice of 16×500W lasers (FS1521M-U-16) or 32×500W lasers (FS1521M-U-32) over the same build area
The FS1521M-U-16 is listed with both circular and square cylinders, so round parts need not be built in a square bed
Runs under argon or nitrogen, with TA15, IN718, IN625, AlSi10Mg and 316L on the material list
Layer thickness from 0.02 to 0.1 mm at a scanning speed of up to 10 m/s

Limitations

External dimensions of 13750×6530×6950mm and a weight of approx. 65000 KG call for a purpose-prepared hall and foundation
Inert gas consumption of 35 - 40 L / min has to be sustained for builds that can reach 1650 mm in height
The FS1521M-U-32 is listed with the square cylinder only; the circular cylinder appears only under the FS1521M-U-16
Ti6Al4V and GH4099 carry an asterisk in the material list, so their status should be confirmed before planning work in them
Supply is 400V three-phase at 125A/160A, and US sites depend on a transformer sold with the machine

Best For

One-piece metal parts up to 1510 mm across and 1650 mm tall Large rings and casings on the Φ1510×1650mm circular cylinder Large-section builds where 32×500W lasers share each layer Work in TA15, IN718, IN625, AlSi10Mg or 316L

Frequently Asked Questions

01 What is the build size of the Farsoon FS1521M?

The effective build size is 1510×1510×1650 mm on the square cylinder and Φ1510×1650mm on the circular cylinder. The cylinders themselves are listed as 1530×1530×1650mm and Φ1530×1650mm. The circular cylinder is listed for the FS1521M-U-16 only.

02 What is the difference between the FS1521M-U-16 and the FS1521M-U-32?

The laser count and the cylinder choice. The FS1521M-U-16 has 16×500W fiber lasers and is listed with a circular or a square build cylinder. The FS1521M-U-32 has 32×500W fiber lasers and is listed with the square cylinder. Layer thickness, scanning speed, gas and external dimensions are given as single figures for both.

03 How much space and floor capacity does the FS1521M need?

The external dimensions are 13750×6530×6950mm and the machine weight is approx. 65000 KG. For scale, the FS621M Pro is listed at approx. 13000 KG (28660.1 lb). Plan the hall height, the crane access and the foundation around those figures, and add the weight of the material in a full cylinder.

04 What power and gas supply does the FS1521M need?

For Europe and China the table gives 400V±10%, 3~/N/PE, 50Hz at 125A/160A, without saying which current applies to which laser count. For the US a transformer is sold with the machine. Inert gas is argon or nitrogen at 35 - 40 L / min, and the operating ambient temperature is 22-28°C.

05 Which materials are listed for the FS1521M?

TA15, IN718, IN625, AlSi10Mg and 316L are listed without qualification. Ti6Al4V and GH4099 are listed with an asterisk, and the table does not say what the asterisk means, so ask Farsoon about those two before committing to them. The list ends with a note that more materials are to come.
