How much does the Farsoon FS350M cost?

Price estimate

Uncertain

We do not have a price for the Farsoon FS350M 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

Four or six lasers over a 425×350×400 mm (16.7×13.8×15.7 in) effective build size define the Farsoon FS350M, a multi-laser metal additive manufacturing machine laid out to fill a rectangular plate quickly rather than to build tall.

The laser rows are split by version. The FS350M-4 is listed with 4×500W fiber lasers, or 4×1000W with Beam Shaping. The FS350M-6 is listed with 6×500W, or 6×1000W with Beam Shaping. That is four combinations on one frame, and the choice between them is a throughput decision: more beams working a layer at once shortens each layer on a full plate, while a build with a few small parts gains much less.

The build cylinder measures 433×358×400 mm (17.1×14.1×15.7 in). Farsoon notes that the height includes the build plate, so the tallest part is 400 mm less the plate thickness, a figure the table does not give. The bed is rectangular, 425 mm by 350 mm effective, which suits rows of parts or one long component laid along the 425 mm side.

For a machine with up to six lasers the listed weight is modest: approx. 3300kg (7275.3 lb), the same figure given for the single-laser FS273M at approx. 3300 kg (7275.3 lb). External dimensions are 3260×1850×2300 mm (128.3×72.8×90.6 in). The supply row for Europe and China reads 400V±10%, 3~/N/PE, 50Hz, 50A/60A/80A. Three currents are listed against four laser combinations and the table does not assign them, so get the figure for the chosen version in writing before the electrical work is planned. A transformer is sold with the machine for the US.

Materials listed outright are 316L, AlSi10Mg, Ti6Al4V, TA15 and AlMgSc. 17-4PH, ST1 and Maraging Steel Grade 300 are marked with an asterisk that is not explained. Gas is argon or nitrogen at 3-5 L / min, and the layer range is 0.02~0.1 mm (0.0008-0.0039 in).

Strengths & Limitations

Strengths

Listed with four lasers (FS350M-4) or six lasers (FS350M-6) on the same 425×350×400 mm (16.7×13.8×15.7 in) effective build size
Each version is offered at 500W per laser or at 1000W per laser with Beam Shaping
Rectangular bed, 425 mm by 350 mm effective, for rows of parts or one long component
Listed weight of approx. 3300kg (7275.3 lb) and external dimensions of 3260×1850×2300 mm (128.3×72.8×90.6 in)
AlMgSc is on the material list without an asterisk, next to 316L, AlSi10Mg, Ti6Al4V and TA15

Limitations

The 400 mm (15.7 in) build height includes the build plate, so usable part height is lower
The supply row lists 50A/60A/80A without saying which laser version each current belongs to
17-4PH, ST1 and Maraging Steel Grade 300 are listed with an unexplained asterisk
No nickel alloy appears in the material list for this model

Best For

Full plates of small and medium parts worked by 4 or 6 lasers at once Aluminium work in AlSi10Mg or AlMgSc Parts up to 425 mm long that stay under 400 mm including the build plate Series work in 316L, Ti6Al4V or TA15

Frequently Asked Questions

01 What is the difference between the FS350M-4 and the FS350M-6?

The number of lasers. The FS350M-4 has four fiber lasers, listed as 4×500W or as 4×1000W with Beam Shaping. The FS350M-6 has six, listed as 6×500W or as 6×1000W with Beam Shaping. Build size, layer thickness, scanning speed and external dimensions are given as single figures covering both.

02 How tall a part can the Farsoon FS350M build?

The effective build size is 425×350×400 mm (16.7×13.8×15.7 in), and the table states that the height includes the build plate. The real part height is therefore 400 mm minus the thickness of the plate in use. The plate thickness is not in the table.

03 What electrical supply does the FS350M need?

For Europe and China: 400V±10%, 3~/N/PE, 50Hz, with 50A/60A/80A listed. The table does not say which current goes with which laser configuration, so confirm it for the version being ordered. For the US, a transformer is sold with the machine.

04 Which materials are listed for the FS350M?

316L, AlSi10Mg, Ti6Al4V, TA15 and AlMgSc are listed without qualification. 17-4PH, ST1 and Maraging Steel Grade 300 have an asterisk, and the table gives no key for it. The inert gas is argon or nitrogen at 3-5 L / min.

05 How heavy is the FS350M and how much floor does it take?

Approx. 3300kg (7275.3 lb), within external dimensions of 3260×1850×2300 mm (128.3×72.8×90.6 in). The FS422M is listed at approx. 3700 KG (8157.1 lb). The room needs to hold 22-28°C (71.6-82.4℉).
