Machine Comparison
EOS M 100 vs EOS M 400-4
EOS vs EOS · Metal Additive Manufacturing
Summary
The EOS M 100 and the EOS M 400-4 are both metal additive manufacturing systems with Yb-fiber lasers, but they are far apart in size and serve different jobs. The EOS M 100 has one 200 W laser and a round Ø 100 x 95 mm (Ø 3.94 x 3.74 in) build volume. The EOS M 400-4 has four lasers, 4 x 400 W, and a 400 x 400 x 400 mm (15.7 x 15.7 x 15.7 in) build volume.
The EOS M 400-4 is stronger on laser output and 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 5140 x 2490 x 2625 mm (202.4 x 98.0 x 103.3 in).
Specifications Comparison

|---|---|---|
| Laser Source | Yb-fiber laser | Yb-fiber laser; 4 x 400 W |
| Laser Power | 200 W | 4 x 400 W ▲ |
| Build Volume | Ø 100 x 95 mm (Ø 3.94 x 3.74 in) | 400 x 400 x 400* mm (15.7 x 15.7 x 15.7 in) |
| Number of Lasers | 1 | 4 ▲ |
| Floor Space | 800 x 950 x 2,250 mm (31.5 x 37.4 x 88.6 in) | 5140 x 2490 x 2625 mm (202.4 x 98.0 x 103.3 in) |
Advantages
EOS M 100
- Far smaller machine: 800 x 950 x 2,250 mm against 5140 x 2490 x 2625 mm
- Ø 100 x 95 mm build volume matched to small detailed parts
- Suits laboratories and small shops working in cobalt chrome and precious metals
EOS M 400-4
- Four lasers, 4 x 400 W, against one 200 W laser
- 400 x 400 x 400 mm (15.7 x 15.7 x 15.7 in) build volume against Ø 100 x 95 mm
- Suited to series production with its four lasers working in parallel
Verdict
Part size and volume make this choice. The EOS M 100 is for small detailed parts in a laboratory or small shop: one 200 W laser, a Ø 100 x 95 mm build volume and a machine that stands on 800 x 950 mm. The EOS M 400-4 is for series production and large single parts up to 400 x 400 x 400 mm, with 4 x 400 W of laser power and the floor space to match. Few buyers will weigh one against the other.
