During the first decade of direct metal laser-sintering (DMLS), the metals employed were generally ones developed specifically for DMLS, rather than those used in traditional metalforming methods. But in recent years, the range of available powder metals and the production quality of DMLS parts have advanced considerably, driving new interest in rapid manufacturing. Greater acceptance of rapid manufacturing has, in turn, encouraged further development of metals for DMLS that are analogous to existing, conventional materials. For instance, titanium-based alloys are commonly used in applications with demanding requirements, but parts are typically expensive to manufacture conventionally, because titanium is generally difficult to cast and to machine. For this reason, titanium alloys for DMLS are well worth exploring. EOS Titanium Ti64 is a pre-alloyed Ti6AlV4 alloy, characterized by excellent mechanical properties and corrosion resistance combined with low specific weight and biocompatibility. Parts built from this alloy can be machined, spark-eroded, welded, micro-shot-peened, polished, and coated, if required. Typical uses include aerospace and medical applications.
