3D printing cannot utilize the benefit of mass production. Producing one item takes a lot of time and if more 3D printers are installed, the cost of purchase would diminish the benefit of bulk production. However, many consider 3D printers as the future of producing unique items. Which of the following most supports the claim that 3D printing would be successful in future for producing unique items?
Show answer & explanation
Correct answer: C
Explanation
The passage highlights that the main drawback of 3D printing is the high purchase cost of machines, which diminishes the economic viability of production.
• Option (C) directly addresses and resolves this major constraint by stating that 3D printing machines will become cheaper over the next five years, reducing production costs.
• Lower machine costs make it economically viable to produce unique items in the future, thus providing the strongest support to the claim.
Therefore, Option (C) is the correct choice.
