TRIMET Offers Alloy for 3D-Printing
TRIMET Aluminium SE/DE is introducing a new aluminium alloy for Additive Manufacturing (AM). The alloy trimal®-05AM is suitable for ultra-high-strength serial parts without subsequent heat treatment process steps. In cooperation with the Leibniz Institute for Material-Oriented Technologies, Bremen/DE, TRIMET conducted a research project to determine the suitability of the new alloy for the SLM process used in 3D-printing. The new material enables the expansion of AM, particularly in the transport sector with its high demand for aluminium materials.
Under the name trimal®-05AM, TRIMET now offers an aluminium alloy that the materials specialist has developed specially for the production of light metal parts in 3D-printing. The alloy, which is based on the material trimal®-05 developed by TRIMET, is suitable for AM processes that use Selective Laser Melting (SLM) for the production of ultra-high-strength serial parts without subsequent heat treatment.
“With the new alloy, we are expanding the application areas for aluminium. The transport sector alone increasingly relies on additive manufacturing, thereby raising the demand for materials that have been developed for this process,” said Thomas Reuther, member of the Executive Board of TRIMET Aluminium SE.
In 3D-printing, the alloy, cast as ingots, is atomized into powder. In the process, the material is liquefied and atomized under high pressure to form metal drops, which then solidify into spherical powder particles. Using SLM, the powder-based material is applied in layers to a base plate and completely remelted locally using laser radiation. After solidification, a solid material layer is brought about. This cycle is repeated until the component is produced completely.
