Transcript:

A new approach to making everything from jet engines to toys, called 3D printing, is creating a revolution in manufacturing — and a small company called Sigma Labs, Inc has an enabling technology that can make it happen. In traditional manufacturing, companies start with metal or other materials, then cut, shape or drill the material to get the finished products. In the late 1980s, however, researchers at MIT came up with a radical new idea. Instead of cutting material away, why not build things by adding layer after successive layer? The method they developed was similar to printing ink onto paper, only in three dimensions. 3D printing, also called additive manufacturing, is now becoming big business. GE Aviation uses it to build jet engine fuel nozzles, for instance, instead of welding together 20 small pieces. Technology Review recently named additive manufacturing one of its 10 "Breakthrough Technologies.

Option 4: "3D Printing or addictive manufacturing is creating a revolution in technology by Sigma Labs. The chronological timeline of how 3D Printing came into existence was discussed."

Explanation: This option is correct because the text outlines the historical development of 3D printing, starting from the late 1980s with MIT's research to its current applications in manufacturing. It captures the essence of the text's focus on the evolution of 3D printing technology.

Option 1: "3D Printing or addictive manufacturing is creating a revolution in technology by Sigma Labs. The differences between traditional printing & 3D printing was discussed."

Explanation: This option incorrectly states that the text discusses the differences between traditional printing and 3D printing. The text focuses on the revolutionary nature of 3D printing and its development, rather than comparing it to traditional printing methods.

Option 2: "3D Printing or addictive manufacturing is creating a revolution in technology by Sigma Labs. The process of preparing 3D prints was discussed."

Explanation: This option is incorrect because the text does not detail the process of preparing 3D prints. Instead, it emphasizes the revolutionary impact of 3D printing and its comparison to traditional manufacturing methods.

Option 3: "3D Printing or addictive manufacturing is creating a revolution in technology by Sigma Labs. The advantages of 3D printing was discussed."

Explanation: This option is incorrect as it suggests that the text discusses the advantages of 3D printing. While the text highlights the revolutionary aspect of 3D printing, it does not specifically enumerate its advantages.
