Höganäs Digital Metal® System - Additive Manufacturing of Small Complex Metal Parts

Digital Metal® belongs to the Höganäs Group. Höganäs is a global specialist in metal powders and additive manufacturing.

digital metal technology

Höganäs' Digital Metal® system is based on precision ink-jet printing on a powder bed. Components are materialised in our 3D printer, which builds the object layer-by-layer, using metal powder and precision ink-jet. Once this process is complete, the object is sintered for strength. The result is a metal component or metal part, with high-resolution and tolerance.

What Digital Metal® technology can be used for

Höganäs Digital Metal® technology is most suitable for small components of complex shape for prototype or series production for various market segments, including non-critical components in the aerospace and medical sectors. Today, Digital Metal® predominantly manufactures parts or components in stainless steel. However, other materials such as titanium, silver and copper are close to commercialisation.

Advantages of 3D metal printing technology

  • 'Impossible' objects become possible. 3D metal printing allows the production of complex objects that would be costly or impossible to produce if traditional methods were employed. This is great news for industrial designers, who can utilise their full creativity and explore the new territory 3D metal printing opens up for them
  • Fast track production. In today's fast-paced, competitive environment, producers face shorter product lifecycles and greater product variety. New and quicker ways to produce and get your creations to market is crucial, and 3D printing is the way to achieve this goal. With Höganäs technology, Digital Metal® can take your product from concept to completion in less than two weeks
  • Cost-effective production. 3D metal printing offers a cost-effective way of producing complex metal parts and is the ideal solution for the manufacture of mass-customised components or flexible serial volumes. It also keeps waste down to an absolute minimum

Surface quality of metal components after sintering

micron tolerances digital metal

Surface roughness after sintering is typically Ra 6 but can be improved easily with traditional surface treatment processes to Ra 3 or better.

The benefit of Höganäs Digital Metal® printing technology is that printing can be conducted at room temperature, without any powder particles melting. The melting of particles tends to occur with competing laser or electron beam technology. Digital Metal® printing results in high tolerances, a high level of surface finish and high levels of detail.

Micron tolerances with Digital Metal® printing

Höganäs Digital Metal® technology allows tolerances of at least 100 microns, with holes and wall thicknesses down to 300 microns. Cleaning of printed components is permitted by the formation occurring at room temperature.

In addition to this, there is no need to build a support structure during printing because the components are supported by the powder bed in the build box. The whole volume of the build box can be maximised and the components can be packed tightly because no account of thermal conductivity needs to be taken. The process is flexible because forming and sintering can be completed in separate steps with different equipment. This means that the forming step can be fully maximised.
