Machine Comparison
EOS M 100 vs EOS M 290
EOS vs EOS · Metal Additive Manufacturing
Summary
The EOS M 100 and the EOS M 290 are both single-laser metal additive manufacturing systems with a Yb-fiber laser, but they serve different jobs. The EOS M 100 is a small machine with a 200 W laser and a round Ø 100 x 95 mm (Ø 3.94 x 3.74 in) build volume. The EOS M 290 has a 400 W laser and a 250 x 250 x 325 mm (9.8 x 9.8 x 12.8 in) build volume.
The EOS M 290 is stronger on laser power, with twice the wattage, and on part size. The EOS M 100 is stronger on space: it measures 800 x 950 x 2,250 mm (31.5 x 37.4 x 88.6 in) against 2680 x 2120 x 2400 mm (105.5 x 83.5 x 94.5 in).
Specifications Comparison
| Specification | EOS M 100 | EOS M 290 |
|---|---|---|
| Laser Source | Yb-fiber laser | Yb-fiber laser; 1 x 400 W |
| Laser Power | 200 W | 400 W ▲ |
| Build Volume | Ø 100 x 95 mm (Ø 3.94 x 3.74 in) | 250 x 250 x 325* mm (9.8 x 9.8 x 12.8 in) |
| Number of Lasers | 1 | 1 |
| Floor Space | 800 x 950 x 2,250 mm (31.5 x 37.4 x 88.6 in) | 2680 x 2120 x 2400 mm (105.5 x 83.5 x 94.5 in) |
Advantages
EOS M 100
- Smaller machine: 800 x 950 x 2,250 mm (31.5 x 37.4 x 88.6 in) against 2680 x 2120 x 2400 mm
- Round Ø 100 x 95 mm build volume sized for small detailed parts
- Suits laboratories and small shops working in cobalt chrome and precious metals
EOS M 290
- 400 W laser against 200 W
- 250 x 250 x 325 mm (9.8 x 9.8 x 12.8 in) build volume against Ø 100 x 95 mm
Verdict
These machines do not compete for the same parts. The EOS M 100 fits laboratories and small shops making small detailed parts, such as cobalt chrome and precious-metal work, that sit inside Ø 100 x 95 mm and where a machine standing on 800 x 950 mm matters. The EOS M 290 fits workshops building larger parts up to 250 x 250 x 325 mm with a 400 W laser. Pick by the largest part you expect to build.
