FS271M

The FS271M is an SLM 3D printer from Farsoon Technologies with a 275 x 275 x 320 mm build volume.

Specifications

Farsoon FS271M: Technical Overview

Laser System

One or two Yb fiber lasers (~1070 nm) rated at 500 W each. Single-laser is standard; dual-laser configuration increases throughput without changing the open parameter access. Scan speed up to 10 m/s: competitive with leading Western systems in the class.

Platform and Build Volume

Build envelope 275 × 275 × 320 mm with a minimum layer thickness of 20 µm: among the finest available in metal LPBF, enabling exceptional detail resolution. Recoater blade is configurable as steel scraper or rubber blade.

Protective Atmosphere.

Calibration

Calibration Protocol: FS271M

Laser Power

Measure actual power at platform monthly with a power meter; acceptable deviation ±3% of set value. At > ±5%: laser service check required.

Scanner Calibration

XY calibration with BuildStar and standard plate before each new material campaign. Single-laser system: simpler calibration without overlap zones.

Parameter Window (DoE)

For new materials: systematic DoE with 10×10×10 mm cubes, varying P, v, h, t.

Common defects

Common Defects: FS271M

Porosity

Primary risk with the open system due to incorrectly defined user parameters. Solution: systematic VED DoE; powder drying; HIP for critical parts.

Distortion and Residual Stresses

Lack of built-in platform heating in base configuration increases thermal gradient. Solution: add platform heating (option); optimise support structures; island scan strategy.

Recoater Streaking

With single-laser configuration at high VED, spatter is more concentrated.

What it is used for

Use Cases: FS271M

R&D Laboratories
