Digital Steel Releases Two New Superalloys for Steel 3D Printing in Excessive Environments

Just a few years in the past, metallic powder producer the Höganäs Group acquired Digital Steel, a small Sweden-based firm with a proprietary binder jetting know-how of the identical identify that was developed in 2013. The corporate produced greater than 200,000 metallic components earlier than its DM P2500 metallic 3D printer was even made commercially obtainable two years in the past.

Together with its half manufacturing rely, Digital Steel has continued to develop, introducing a completely automated manufacturing idea final fall, and simply this week launched two new superalloy-grade supplies meant to be used in excessive purposes.

“We have now been receiving certified requests for these supplies from numerous giant firms. Many producers throughout the aerospace and automotive enterprise have lengthy been anticipating high-quality superalloys which are appropriate for 3D printing,” mentioned Ralf Carlström, the Common Supervisor at Digital Steel. “Now we will supply them the proper mixture – our distinctive binder jetting know-how and superalloys which are specifically developed for our printers.”

The corporate was the primary to commercialize high-precision 3D metallic printers for serial manufacturing of small, high-volume parts. Digital Steel’s excessive precision binder jetting know-how makes it attainable to 3D print advanced, detailed, top quality objects with a superior floor end.

The kinds of firms that require advanced components with glorious floor end are from the identical industries – aerospace, automotive,chemical, and industrial – which are seeing an growing demand for 3D printable superalloys. To satisfy this demand, Digital Steel has launched two of its personal superalloy grades that can be utilized in a lot of these excessive environments: DM 625 and DM 247.

Materials knowledge – Typical values

Superalloys are metallic supplies that, even when subjected to excessive temperatures and stress, nonetheless present glorious corrosion resistance and energy, which makes them well-suited for more difficult purposes. Sadly, utilizing non-weldable supplies, like MAR M247, in 3D printing just isn’t straightforward, because of inherent thermal gradients and excessive solidification charges.

However Digital Steel supplies are completely different. Its binder jetting know-how has some distinctive properties that make it attainable to 3D print superalloys – even grades that aren’t weldable – with close to full density. The tactic works by printing in an ambient temperature with out making use of warmth, and is then adopted with a sintering step. Densification happens with out melting in the course of the sintering course of, and through cooling it occurs with solely a minimal quantity of thermal gradients.

DM 247 is predicated on MAR M247, which is non-weldable and infrequently utilized in purposes that cope with elevated temperatures, comparable to materials for turbine blades. DM 625 is an Inconel 625-grade, which purposes from aerospace and chemical processing equpiment to the nuclear and seawater industries.

Digital Steel’s new DM 625 and the DM 247 superalloys now be part of the corporate’s present vary of supplies, which additionally consists of titanium Ti6Al4V and stainless-steel 17-4PH and 316L.
