Question 4: 3D printing technology is utilized in the medical field for the creation of prosthetics.

A. Ano

B. Ne

Explanation: The study materials explicitly mention that 3D printing has use cases in medicine, specifically for prosthetics.

Question 5: Based on the provided study materials, which of the following statements about Prusa Research are true?

A. It was founded in 2012 by Josef Prusa.

B. It is the largest 3D printer manufacturer in the world.

C. It is recognized as an OpenSource company.

D. They shipped over 50,000 printers by 2018.
