EOS marks another milestone in industrial 3D printing of metals and polymers with its EOS StainlessSteel 17-4PH IndustryLine.

The material is an iron-based metal alloy powder. Designed for the EOS M 290 metal system, it meets the requirements of serial production via additive manufacturing. Indeed, the product ensures reproducible part quality via its latest degree of data reliability for material properties of the end product.

Like other 3D printing technologies, it enables to save time and costs in downstream quality assurance and part qualification.

Notice is to be made that traditional methods required a limited statistical study to measure industrial 3D printing material properties. These properties include elongation at break, tensile strength, or hardness of a finished part.

Dr. Tobias Abeln, Chief Technical Officer (CTO) at EOS explains: “Planning security and reliability are top priorities for customers who are engaged in serial manufacturing. For its StainlessSteel 17-4PH IndustryLine, EOS provides reliable and statistically proven data for the most important material properties of finished parts.”

He continues: “This significantly raises quality standards in Additive Manufacturing. The customer can use the data 1:1 to qualify the technology for large-scale production and therefore minimize the time required as well as cut the cost of in-house material and process qualification.”

Industrial application areas for EOS StainlessSteel 17-4PH IndustryLine

EOS StainlessSteel 17-4PH IndustryLine is a high-strength, easily curable, highly corrosion- and acid-resistant material. That’s why it is recommended for manufacturing surgical and orthopedic instruments.

Furthermore, parts can be additionally processed, micro-blasted, and polished directly after the 3D printing  process or also after heat treatment.

The existing material data sheets and batch-specific material test certificates contain extensive information regarding the tests used as well as the material standards.
