1 During 1918 there were many problems in the United States. 2  One of these major problems was the influenza. 3  Its symptoms were headaches, and queasy feelings in the stomach. 4  This disease had infected the people of Denver, and other cities across the nation.
Direct metal laser sintering (DMLS) is an additive manufacturing technique that uses a carbon dioxide laser fired into a magnesium substrate to sinter powdered material (typically metal), aiming the laser automatically at points in space defined by a 3D model, binding the material together to create a solid structure.
The types and properties of the printing ink dominate the fabrication process. In principle, any metal with a low melting point (or less than 300Â°C) can be selected as a printing ink on condition that an appropriate cooling liquid is available.ompared to conventional metal prototyping techniques, liquid phase 3D printing offers several distinct advantages: (1) At a relatively high speed of manufacturing, the process of printing metal objects in a liquid phase can be used to form three-dimensional structures.
