Capabilities of Laser Printers with Different Power

The paper provides data on the structures and specifications of laser printers for 3D metal printing. The printers were engineered in Research and Educational Center "Modern manufacturing technologies" in Tomsk Polytechnic University, Tomsk, Russia. The essential difference of the given printers is their laser power. The experimental research has shown that the setups with a more powerful laser (500W) enable synthesizing the objects of higher quality in a shorter period of time. The paper also presents data on forming samples structure with the use of 3D printing.
