Machine Comparison
EOS M 290 vs EOS M 300-4
EOS vs EOS · Metal Additive Manufacturing
Summary
The EOS M 290 and the EOS M 300-4 are both metal additive manufacturing systems built around 400 W Yb-fiber lasers, but they serve different jobs. The EOS M 290 has one laser and a 250 x 250 x 325 mm (9.8 x 9.8 x 12.8 in) build volume. The EOS M 300-4 has four, 4 x 400 W in a full-overlap architecture, and a 300 x 300 x 435 mm (11.8 x 11.8 x 17.1 in) build volume.
The EOS M 300-4 is stronger on laser count and part size. The EOS M 290 asks less of the building: approx. 1350 kg (2976 lbs) against approx. 5500 kg (12125 lbs), and 2680 x 2120 x 2400 mm (105.5 x 83.5 x 94.5 in) against 5221 x 2680 x 2340 mm (205.6 x 105.5 x 92.1 in).
Specifications Comparison
| Specification | EOS M 290 | EOS M 300-4 |
|---|---|---|
| Laser Source | Yb-fiber laser; 1 x 400 W | Yb-fiber laser; 4 x 400 W |
| Laser Power | 400 W | 4 x 400 W ▲ |
| Build Volume | 250 x 250 x 325* mm (9.8 x 9.8 x 12.8 in) | 300 x 300 x 435* mm (11.8 x 11.8 x 17.1 in) |
| Number of Lasers | 1 | 4 (full-overlap architecture) ▲ |
| Machine Weight | approx. 1350 kg (2976 lbs) | approx. 5500 kg (12125 lbs) |
| Floor Space | 2680 x 2120 x 2400 mm (105.5 x 83.5 x 94.5 in) | 5221 x 2680 x 2340 mm (205.6 x 105.5 x 92.1 in) |
Advantages
EOS M 290
- Lighter machine: approx. 1350 kg (2976 lbs) against approx. 5500 kg (12125 lbs)
- Smaller floor space: 2680 x 2120 x 2400 mm against 5221 x 2680 x 2340 mm
- Suits builds where a single 400 W laser gives enough output
EOS M 300-4
- Four lasers, 4 x 400 W, against one 400 W laser
- Full-overlap architecture, so all four lasers can expose a single large part
- 300 x 300 x 435 mm (11.8 x 11.8 x 17.1 in) build volume against 250 x 250 x 325 mm
Verdict
Choose by throughput. The EOS M 290 fits workshops whose builds are served by a single 400 W laser and whose parts stay inside 250 x 250 x 325 mm; it is also the easier machine to site at approx. 1350 kg (2976 lbs). The EOS M 300-4 fits series production, with 4 x 400 W over a 300 x 300 x 435 mm build volume, provided the floor can carry approx. 5500 kg (12125 lbs).
