Machine Comparison
EOS M 300-4 vs EOS M 400-4
EOS vs EOS · Metal Additive Manufacturing
Summary
The EOS M 300-4 and the EOS M 400-4 are both four-laser metal additive manufacturing systems with 4 x 400 W of Yb-fiber laser power. Laser count and power are shared, so the choice turns on the build volume and how the lasers cover it.
The EOS M 400-4 has the wider build area: 400 x 400 x 400 mm (15.7 x 15.7 x 15.7 in) against 300 x 300 x 435 mm (11.8 x 11.8 x 17.1 in). The EOS M 300-4 builds taller, to 435 mm (17.1 in), and its entry lists a full-overlap architecture for the four lasers. The machines are close in size: 5221 x 2680 x 2340 mm against 5140 x 2490 x 2625 mm, and approx. 5500 kg (12125 lbs) against approx. 4900 kg (10803 lbs).
Specifications Comparison
| Specification | EOS M 300-4 | EOS M 400-4 |
|---|---|---|
| Laser Source | Yb-fiber laser; 4 x 400 W | Yb-fiber laser; 4 x 400 W |
| Laser Power | 4 x 400 W | 4 x 400 W |
| Build Volume | 300 x 300 x 435* mm (11.8 x 11.8 x 17.1 in) | 400 x 400 x 400* mm (15.7 x 15.7 x 15.7 in) |
| Number of Lasers | 4 (full-overlap architecture) | 4 |
| Machine Weight | approx. 5500 kg (12125 lbs) | approx. 4900 kg (10803 lbs) |
| Floor Space | 5221 x 2680 x 2340 mm (205.6 x 105.5 x 92.1 in) | 5140 x 2490 x 2625 mm (202.4 x 98.0 x 103.3 in) |
Advantages
EOS M 300-4
- Taller build volume: 435 mm (17.1 in) of height against 400 mm (15.7 in)
- Full-overlap architecture listed for its four lasers, so all four can expose one large part
EOS M 400-4
- Wider build area: 400 x 400 mm (15.7 x 15.7 in) against 300 x 300 mm (11.8 x 11.8 in)
- Lighter at approx. 4900 kg (10803 lbs) against approx. 5500 kg (12125 lbs)
Verdict
With the same 4 x 400 W of laser power, pick by part shape. The EOS M 400-4 suits large single parts and plates of repeated parts that need its 400 x 400 mm area. The EOS M 300-4 suits tall parts up to 435 mm (17.1 in) and single large parts exposed by all four overlapping lasers. Floor space is nearly the same; the weight to plan for is approx. 5500 kg (12125 lbs) against approx. 4900 kg (10803 lbs).
