Farsoon FS1311M — Technical data

The FS1311M, also called FS1311M-U, is a large-format metal laser melting system that Farsoon introduced in spring 2026. Its build cylinder measures 1,340 × 1,340 × 1,650 mm, with 1,310 × 1,310 × 1,650 mm usable. Sixteen fibre lasers of 500 W or, with beam shaping, 1,000 W work in parallel; for Ti6Al4V Farsoon quotes up to 1,440 cm³/h at 150 µm layer thickness. The machine weighs around 52 t, the build level is raised and downstream processes are arranged below. A three-station layout, closed powder management and permanent filtration are meant to allow parallel operations. Target groups are aerospace, automotive and energy.

The FS1311M is unlikely to appear as a used machine in the near future. If one is offered, structural load, hall height of at least 6.5 m, crane capacity and an inert gas demand of 25–35 l/min are the first checkpoints. Technically, documentation of all 16 lasers including calibration, filter status and powder circuit count. Plan reassembly and acceptance only together with Farsoon Europe.

2 · Let us search

Nothing suitable? We will search for you – or get an e-mail as soon as a matching machine comes in.

3 · Have parts printed

Not worth your own machine? We produce your parts – request from the LayerByLayer 3D printing service.

Buy or have it printed? For small or changing quantities, having parts printed is often cheaper than your own machine. If you regularly fill many build jobs, your own machine pays off.
