EOS Premium and Core metal materials portfolio expands

65 0

EOS has expanded its range of Premium and Core metal materials with one new Premium and 7 new Core products for its EOS M 290, EOS M 300-4 and EOS M 400-4 3D printers.

The new Core products alone are claimed to enable 50 percent faster build rates and increase the productivity of the EOS M 290 3D Printer considerably.

EOS introduced Technology Readiness Levels (TRLs) in 2019 for materials and processes to classify ‘technological maturity levels’ for easy user orientation, with Core materials fixed at TRL 3 and 5, and Premium at 7-9.

The Premium moniker attaches particular importance to repeatable part quality essential for serial production.

“With more companies crossing the border from prototyping to serial production based on AM, the demand for reliable data for materials and built parts is growing,” explained Hanna Pirkkalainen, product manager Metal Materials at EOS.


New EOS Premium Material


EOS ToolSteel 1.2709 (TRL 7)

EOS ToolSteel 1.2709 is an ultra-high strength and hardness maraging steel for demanding moulding applications.

This tool steel has an excellent fatigue strength and improved polishability, which with different post process heat treatments has further adjustable properties.

The new Premium material is validated for the EOS M 290 system and typical applications ranging from plastic injection moulding, to extrusion tools, hot pressing tools to die casting tools for aluminium and zinc alloys.


New EOS Core Materials

 

EOS Aluminum AlSi10Mg for EOS M 290 systems (TRL 3)

The new 60µm process developed for the EOS M 290 benefits from the new versatile and ‘cost effective’ AlSi10Mg material which offers high productivity, improved buildability and enables heat treatment to improve ductility.

EOS Titanium Ti64 Grade 5 and Grade 23 for EOS M 290 and EOS M 400-4 systems

The new 80µm processes for both titanium alloys on both systems should result in faster build rates and lower cost-per-part.

Both Ti6AI4V alloys offer excellent mechanical properties: high density with high strength and excellent corrosion resistance.

Typical applications range from aerospace and automotive components to other industrial applications where a combination of low weight with high strength is required.

EOS NickelAlloy IN718 and EOS MaragingSteel MS1 for EOS M 300-4 systems (TRL 3)

The 40 µm 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.

Typical applications range from gas turbine components to instrumentation, power industry and process industry parts.

50 µm EOS MaragingSteel MS1 can create parts with very good mechanical properties, able to be 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.
