Metal Materials for the EOS M 300-4

EOS materials are specially developed for DMLS and undergo strict quality assurance.

EOS NickelAlloy IN718

Parts show excellent tensile, fatigue, creep and rupture strength at temperatures up to 700°C, making it ideal for many high temperature applications.

EOS Maraging Steel MS1

Parts have excellent mechanical properties and are heat-treatable using a simple thermal age-hardening process to obtain superior hardness and strength.

EOS Titanium Ti64

Titanium’s material characteristics make it ideal for many high-performance applications in aerospace, automotive & medical.

EOS Aluminum AlSi10Mg

Parts printed using EOS Aluminum AlSi10Mg offer strength, hardness and dynamic properties as well as excellent thermal properties and low weight.

EOS StainlessSteel 316L

Parts show a high level of corrosion resistance, toughness and ductility as well as a high resistance to acids.

Material Management Metal Materials

The EOS powder handling portfolio offers a wide range of products for advancing and sieving metal powder. The products have different degrees of automation, are suited for small or large powder quantities and can be used flexibly and independently of the respective EOS metal system.

IPM M Powder Station L

The IPM M Powder Station L is the fully-automatic and intelligent material management solution that offers a closed powder cycle in a protective gas atmosphere in just one module.

IPCM-M pro

The IPCM-M pro is a semi-automatic solution that secures easy, fast and safe handling in a closed system. It reduces the steps in the powder handling workflow while keeping the flexibility to use it with multiple machines.

IPCM-M extra

The IPCM-M extra is the manual solution that is flexible in use with multiple machines, easy to scale-up with increasing demand and can be used with all EOS metal systems.


EOS offers tried-and-tested software solutions for all process steps in additive manufacturing – from the preparation of CAD design data and job preparation to quality control.


EOSCONNECT Core is the connectivity solution for monitoring production. EOS systems are IIoT-capable and can be integrated into existing IT infrastructures via EOSCONNECT Core. EOS offers an open interface for this.
