3D printing, or additive manufacturing, is the construction of a three-dimensional object from a CAD model or a digital 3D model. [1] [2] [3] It can be done in a variety of processes in which material is deposited, joined or solidified under computer control, [4] with the material being added together (such as plastics, liquids or powder grains being fused), typically layer by layer.

In 2011, the tinkercad.com website was launched as a web-based 3D modeling tool for WebGL-enabled browsers, [4] and in 2012 the company moved its headquarters to San Francisco. [5] By 2012, over 100,000 3D designs had been published by users. [5] In May 2013, Autodesk announced at a Maker Faire that they would acquire Tinkercad. [6]
Research on the health and safety hazards of 3D printing is new and in development due to the recent proliferation of 3D printing devices. In 2017, the European Agency for Safety and Health at Work has published a discussion paper on the processes and materials involved in 3D printing, potential implications of this technology for occupational safety and health and avenues for controlling ...
In the airline industry an available seat mile is the fundamental unit of production for a passenger-carrying airline. [2] A unit in this case is one seat, available for sale, flown one mile. For example, an aircraft with 300 seats available for sale flying 1,000 statute miles would generate 300,000 ASMs for that particular flight. That the ...
