How much does the EOS M 100 Compact Metal 3D Printer cost?
Estimated price range
Our best estimate for a metal additive manufacturing in this class — not a quote from EOS GmbH. Configuration moves it a long way.
Overview
The EOS M 100 Compact Metal 3D Printer is listed with a cylindrical build volume of Ø100 x 95 mm and a single 200W fiber laser. This model is not in EOS's current lineup as listed here, so the listed figures are unconfirmed.
A cylinder changes how parts are nested. Everything has to fit inside a 100 mm circle and under 95 mm of height, supports included, so the usual job is a plate of many small pieces and not one large one. The accuracy row fits that picture: ±0.05 mm for details under 30 mm, a tolerance stated only for small features. Larger dimensions on a part carry no listed tolerance.
Layer thickness runs from 20 to 80 µm and the build rate is up to 5 cm³/h, material-dependent. The materials row reads CoCr (dental/medical), Ti-6Al-4V ELI, gold alloys, silver alloys and stainless 316L, which places the machine in dental, medical and jewellery work. For anything bigger, the M 290 is listed with 250 x 250 x 325 mm (9.8 x 9.8 x 12.8 in) and a 400 W laser.

Strengths & Limitations
Strengths
- Listed accuracy of ±0.05 mm for details under 30 mm
- Layer thickness range of 20 – 80 µm on a single-laser machine
- Materials row covers CoCr (dental/medical), Ti-6Al-4V ELI, gold alloys, silver alloys and stainless 316L
Limitations
- Build volume is a cylinder of only Ø100 x 95 mm, against 250 x 250 x 325 mm on the M 290
- Build rate of up to 5 cm³/h, material-dependent, from a single 200W fiber laser
- No weight, dimensions, power supply or inert gas are listed for planning the installation

Frequently Asked Questions
01
The listed build volume is Ø100 x 95 mm, cylindrical. A part and its supports must fit within a circle of 100 mm diameter and a height of 95 mm. The M 290, by comparison, is listed with 250 x 250 x 325 mm (9.8 x 9.8 x 12.8 in).
02
The accuracy row gives ±0.05 mm for details under 30 mm. That is a figure for small features only; nothing is listed for longer dimensions, so tolerances across a full 100 mm diameter should be agreed from test parts and not read off this row.
03
The listed materials are CoCr (dental/medical), Ti-6Al-4V ELI, gold alloys, silver alloys and stainless 316L. Layers run from 20 to 80 µm and the build rate is up to 5 cm³/h depending on the material, so expect the rate to differ between alloys.
