EOS has expanded its range of Premium and Core metal materials portfolio for additive manufacturing (AM). The company introduces one new Premium and seven new Core products for the EOS M 290, EOS M 300-4 and EOS M 400-4 systems. Core materials (TRL 3 and 5) were designed with a focus on early market access to new materials and Premium materials (TRL 7-9) were designed with a focus on repeatable part quality aiming towards serial production, the company says.

The Premium material EOS ToolSteel 1.2709 for EOS M 290 systems, is a TRL 7, ultra-high strength and hardness maraging steel for demanding molding applications. Properties are adjustable with different heat treatments after 3D printing. This material is validated for the EOS M 290 system.

The three Core products for AlSi10Mg, Ti64 Grade 5 and 23 with up to 50% faster build rates increase the productivity of the EOS M 290 considerably. With EOS NickelAlloy IN718 and EOS MaragingSteel MS1, two new Core materials are also now available for the EOS M 300-4. The materials portfolio of the EOS M 400-4 has also been extended to include two new and faster Core processes for EOS Titanium Ti64 Grade 5 and EOS Titanium Ti64 Grade 23.

Developed for the EOS M 290 system, the new 60 micron process is classified as Core material with TRL 3. The EOS Aluminum AlSi10Mg material offers high productivity, improved buildability and enables heat treatment to improve ductility.

The new 80 micron processes for both titanium alloys and for both the EOS M 290 and EOS M 400-4 systems enable higher build rates, resulting in lower cost-per-part. Both Ti6AI4V alloys, Grade 5 and Grade 23 offer low density with high strength and excellent corrosion resistance. The new 80 micron processes are optimized for faster production of parts with properties similar to wrought Ti64.

Developed for the EOS M 300-4 system, EOS NickelAlloy IN718 and EOS MaragingSteel MS1 materials come with a TRL 3 classification. EOS NickelAlloy IN718 is a precipitation-hardening nickel-chromium alloy which is characterized by having good tensile, fatigue, creep and rupture strength at temperatures up to 700 ºC (1,290 ºF).

The 50 µm process based on EOS MaragingSteel MS1 is also designed for use on the EOS M 300-4 system. The material also comes with a TRL 3 classification. Parts built with this material are characterized by having very good mechanical properties. The parts can be easily post-hardened to more than 50 HRC to obtain excellent hardness and strength. Typical applications range from injection molding tools and inserts to mechanical engineering parts.
