Scientists have demonstrated a unique 3D printing technology that allows for extremely fast production of metal parts
Researchers at the Massachusetts Institute of Technology (MIT) have developed a new rapid 3D printing technology that uses liquid metal to produce large aluminum components extremely quickly.
This is stated on the Institute’s website.
This process is called LMP. It uses molten aluminum that is guided through a layer of tiny glass beads and quickly solidifies to form a 3D structure. The researchers claim that this new process is at least ten times faster than existing methods of manufacturing metal components.
However, although LMP is equipped with speed, it sacrifices resolution, which is why researchers use it to produce low-resolution objects such as furniture parts. Parts made with LMP remain strong and can withstand drilling and boring. In addition, LMP offers greater durability because the material is kept molten throughout the printing process, reducing the chance of cracking and warping.
Developers recommend combining LMP with other methods that require both speed and high resolution. LMP technology can be useful for creating large components that do not have complex geometry.
This printing method can be applied not only to aluminum but also to other metals. The developers chose aluminum because of its popularity and easy recyclability. They also plan to further develop the technology to improve heating uniformity, prevent sticking, and provide greater control over the molten metal.
