EOS adds 8 new metallic powders and procedures to AM material portfolio


EOS, the world-wide leader in LB-PBF units, has expanded its giving of AM components with the launch of 8 new metallic powders and procedures for use with its M 290, M 300-4, and M 400-4 3D printing certification programs. The new content established consists of just one High quality and 7 Core items, characterized by their Technological innovation Readiness Stages (TRLs) – a substance and system technological maturity classification system launched by EOS in 2019. The aim of the TRL method is to aid with purchaser orientation, providing a standardized, information-backed metric for producers to securely cross the border to serial AM production.

Hanna Pirkkalainen, Products Supervisor of Metallic Elements at EOS, describes: “Depending on certain application prerequisites, customers can decide on amongst Main materials (TRL 3 and 5) with a important focus on early marketplace entry to new elements, and Quality components (TRL 7-9) which connect certain relevance to repeatable part good quality important in serial production.”

The High quality materials

The company’s new TRL 7 materials for the M 290 is ToolSteel 1.2709. It is described as an extremely-high strength maraging steel intended for significant-anxiety molding apps. The metal characteristics superb tiredness resistance and improved polishability, and its houses can be fantastic-tuned with warmth remedies soon after 3D printing certification. The advisable apps include things like plastic injection molding, extrusion resources, hot pressing tools, and die casting instruments.

The Core elements

The M 290 procedure has also acquired a few new Main merchandise – AlSi10Mg, Ti64 Quality 5, and Ti64 Quality 23. The new 60 micron method for AlSi10Mg is categorised as TRL 3, with the material offering speedier create prices, improved buildability, and new heat procedure abilities to improve ductility. The materials is suggested for apps wherever cost-performance is the vital requirement.

The two new 80 micron processes for the titanium alloys (which are also ideal for the M 400-4 method) are optimized for speedy manufacturing of areas with attributes akin to wrought Ti-64. Both of those alloys have reduced density, significant energy, and exceptional corrosion resistance, generating them ideal for aerospace and automotive parts.

Ultimately, the M 300-4 program has been given a 40 micron approach (TRL 3) for Nickel Alloy IN718 and a 50 micron approach (TRL 3) for Maraging Metal MS1. Inconel is a precipitation-hardening nickel chromium alloy with large tensile energy, and excellent exhaustion and creep resistance at temperatures up to 700°C. It is usually applied for significant-tension, substantial-temperature purposes this kind of as gas turbine engine components. The MS1 content is also characterised by its excellent mechanical qualities and can be write-up-hardened to extra than 50 HRC for purposes this sort of as injection molding equipment.

New powders are frequently becoming skilled for metallic AM, spawning a complete host of new apps for the engineering. Just very last week, metal AM professional Amaero introduced that its large-performance 3D printing certification aluminum alloy, Amaero Incredibly hot Al, had entered the national phase (fourth and remaining stage) of international patent approval. The content has superior scandium material and can be heat addressed and age hardened submit-printing. In other places, Protolabs introduced a new cobalt chrome superalloy for its metal laser sintering course of action. The digital prototyping corporation thinks the heat, put on, and corrosion resistant content will disrupt a selection of industries together with oil and fuel.

The nominations for the 2020 3D Printing certification Business Awards are now open up. Who do you think need to make the shortlists for this year’s clearly show? Have your say now.
