The latest news about Digital Metal

Digital Metal extends the range of available material for its 3D printing technology. Ti6Al4V will be offered on top of already existing Stainless 316L and 17-4PH.
Ti6Al4V is widely known and used in the additive manufacturing industry. It combines high strength, hardness and ductility with high corrosion resistance. It also means a 45% weight reduction compared to conventional steel. The Digital Metal Ti6Al4V offer follows ISO 22068. Typical values can be seen in the table.

Material data – typical values
Ultimate tensile strength Yield strength (0,2%) Elongation Hardness
MPa MPa % HRB HRC
316L 520 180 50 55
17-4PH 900 730 6 25
Ti6AI4V 890 790 8 40

 

Digital Metal offers 3D printing of small metal components with a combination of high detail accuracy, high surface finish and tight tolerances.

A 3D printer developed by Digital Metal has successfully been installed at the French CETIM (Centre Technique des Industries Mécaniques/Technical Center for the Mechanical Industry), a non-profit establishment supporting French industry to adapt new technologies. The printer, A DM P2000, is part of a license agreement that was signed last year.
It is equipped with an upgraded build box, an upgraded ink supply system as well as an upgraded powder handling system.
– It is a covered printer, reducing the noise level dramatically, says Hans Kimblad, technical sales manager at Digital Metal. The required safety footprint is also smaller compared to the open printer concept.

Montford, a new Swiss watch maker, uses Digital Metal technology for 3D printing its dials.

At Digital Metal, we are convinced of the endless possibilities with metal powder technology. Our latest customer, Swiss watch maker Montfort, is proof of what can be done. Our 3D-printing technique allowed them the complete freedom of design they were looking for. The beautiful watches are inspired by the Swiss Alps, with dials produced by Digital Metal.

Höganäs extends its 3D printing capability by introducing high performance 17-4 PH stainless steel for Digital Metal printing technology.
17-4 PH enables production of components with high strength and hardness.
The material is a hardening grade exhibiting considerably higher strength compared to the more commonly used austenitic 316L.

It also provides improved corrosion resistance compared to 400 series ferritic stainless steels.
