3D Systems has added two new metal alloys to its material portfolio that are specifically designed to produce high-strength and corrosion-resistant parts. The first, “Certified Scalmalloy”, is a modified aluminum powder designed to bridge the gap between traditional metal alloys such as AlSi10Mg and Ti Gr23, with an excellent strength-to-weight ratio. The second material – “Certified M789”, is a metal alloy with a high level of hardness and a high degree of processing, but without cobalt in its composition.

The materials were developed together with APWORKS and BÖHLER Edelstahl, and certified especially for use with 3D Systems machines. The new powders will find applications in the automotive, aviation, injection molding and energy sectors.

Scalmalloy is dedicated to 3D printing of parts characterized by high weight and load capacity. Its tensile strength is 520 MPa and the yield point is 480 MPa. In internal testing, the material proved to be significantly stronger than AlSi10Mg, and also exceptionally capable of producing high-strength, corrosion-resistant parts.

Certified M789 – also known as BÖHLER M789 AMPO, is optimized for the creation of casting and injection molds and ultra high strength tooling. The metal is not only free from environmentally harmful cobalt, but can be additionally reinforced to achieve a Rockwell hardness of 52 HRC.

Due to these properties, the material can therefore be used to create mold inserts with conformal cooling, and its durability gives it potential use in drill bits and cutting tools in the energy sector. The Certified M789 is also dedicated to use in the automotive industry, particularly for 3D printing of tire molds and powertrain or axle parts.
