Lawrence Livermore National Laboratory announces new metal 3D printing method

US federal research facility, Lawrence Livermore National Laboratory (LLNL) has announced the results of an ongoing three-year research project into direct metal 3D printing. The technology, referred to as ‘Direct Metal Writing’ (DMW) adds to existing metal additive solutions such as selective laser melting (SLM). The technology was developed in collaboration with Worcester Polytechnic Institute, Massachusetts. Unlike SLM, the DMW method eliminates the need for high powered lasers to sinter metal and form 3D structures. The researchers believe their novel process has benefits over more conventional metal additive manufacturing techniques in terms of reliability of the parts produced. Lawrence […]
