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.
Material handling options can allow the laser to run unattended. Significantly higher capital cost than plasma or waterjet. Cutting metals reflective to the laser beam (such as aluminum) can be hazardous to the focusing lens. Can cause micro fracturing on some materials, a detriment for some aerospace applications. Variations in material quality for carbon steel plate as well as surface rust can affect cut results. High cost for cutting assist gas, can be more than $15 per hour. Safety requirements to protect operator from laser beam.
