How much does the Farsoon FS422M cost?

Price estimate

Uncertain

We do not have a price for the Farsoon FS422M 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 FS422M, listed by Farsoon as the FS422M-H-4, is a four-laser metal additive manufacturing machine with a square effective build size of 419mm×419mm×550mm (16.5×16.5×21.7 in). The build cylinder is 425mm×425mm×550mm (16.7×16.7×21.7 in), so the margin between cylinder wall and usable area is small and the square bed can be used almost edge to edge.

Build height is the reason to look at this model. At 550mm (21.7 in) the Z is taller than the bed is wide, which opens the machine to upright parts such as manifolds, housings and ducts that would otherwise have to be split or laid over at an angle. Tall builds are long builds, though: at the listed layer thickness of 0.02~0.1 mm (0.0008-0.0039 in), a part that uses the whole height runs to thousands of layers.

Three laser sets are listed, all with four beams. The fiber laser set is 4×500W or 4×1000W, and a separate 4×1000W set is labelled Beam Shaping. Scanning speed is max. 10 m/s (32.8 ft/s) through F theta lenses. Buyers should settle the laser set early, because the table gives one supply figure, 400V±10%, 3~/N/PE, 50Hz, 30A for Europe and China, and does not break it down by laser power. A transformer is sold with the machine for the US.

The footprint is long: 5000mm×2900mm×2700mm (196.9×114.2×106.3 in), for a listed weight of approx. 3700 KG (8157.1 lb). That weight is only a little above the approx. 3300kg (7275.3 lb) of the FS350M, so floor loading is unlikely to be the constraint; floor area is. Inert gas is argon or nitrogen at 3-5 L / min, and the room has to stay at 22-28°C (71.6-82.4℉).

Four materials are listed without an asterisk: 316L, AlSi10Mg, IN718 and Ti6Al4V. TA15, HX, HAYNES 230, IN625, AlMgSc, CuCrZr, CuSn10 and Pure Copper all carry one, with no key in the table.

Strengths & Limitations

Strengths

Effective build height of 550mm (21.7 in) over a 419mm×419mm (16.5×16.5 in) square bed
Four lasers in every listed set: 4×500W, 4×1000W, or 4×1000W with Beam Shaping
The 425mm cylinder is only slightly wider than the 419mm effective width, so little of the bed is lost at the edges
Listed weight of approx. 3700 KG (8157.1 lb), close to the approx. 3300kg (7275.3 lb) of the FS350M
316L, AlSi10Mg, IN718 and Ti6Al4V are listed without qualification

Limitations

The footprint is 5000mm×2900mm×2700mm (196.9×114.2×106.3 in), a long machine for its build size
Eight of the twelve listed materials, including TA15, IN625, CuCrZr and Pure Copper, carry an unexplained asterisk
The supply row gives 30A only and does not distinguish the 4×500W set from the 4×1000W sets
No six-laser version is listed in the table for this model

Best For

Upright parts that need up to 550mm (21.7 in) of build height Square plates of parts up to 419mm×419mm (16.5×16.5 in) Four-laser production in 316L, AlSi10Mg, IN718 or Ti6Al4V Sites with floor area for a 5000mm×2900mm machine

Frequently Asked Questions

01 What is the build volume of the Farsoon FS422M?

The effective build size of the FS422M-H-4 is 419mm×419mm×550mm (16.5×16.5×21.7 in). The build cylinder is listed as 425mm×425mm×550mm (16.7×16.7×21.7 in). Unlike some other Farsoon tables, this one carries no note that the height includes the build plate, so ask whether the 550mm is net part height.

02 Which laser options does the FS422M have?

All listed options use four lasers. The fiber laser row gives 4×500W or 4×1000W, and a second entry gives 4×1000W with Beam Shaping. The scanner uses F theta lenses and the scanning speed is max. 10 m/s (32.8 ft/s).

03 How much floor space does the FS422M take?

External dimensions are 5000mm×2900mm×2700mm (196.9×114.2×106.3 in) and the weight is approx. 3700 KG (8157.1 lb). Allow working room around that footprint for loading the cylinder and handling material, which the table does not quantify.

04 Can the FS422M print copper?

CuCrZr, CuSn10 and Pure Copper are all on the material list, but each has an asterisk and the table does not say what the asterisk means. The materials listed without one are 316L, AlSi10Mg, IN718 and Ti6Al4V. Confirm the status of the copper alloys with Farsoon, and ask which laser set they are run on.

05 What utilities does the FS422M require?

Electrical supply for Europe and China is 400V±10%, 3~/N/PE, 50Hz, 30A; for the US a transformer is sold with the machine. Argon or nitrogen is consumed at 3-5 L / min. The operating ambient temperature is 22-28°C (71.6-82.4℉). The control PC runs 64 bit Windows 10 with BuildStar and MakeStar software.
