A student researching 3D printing has taken the following notes:
• 3D printing creates objects by depositing material layer by layer • The technology was invented in the 1980s for industrial prototyping • Medical applications include custom prosthetics and organ scaffolds • Aerospace companies print lightweight parts for aircraft • Consumer 3D printers now cost under $200
The student wants to show how 3D printing has evolved from industrial to consumer use. Which choice most effectively uses relevant information from the notes?
3D printing creates objects by depositing material layer by layer.
Originally developed for industrial prototyping in the 1980s, 3D printing has become accessible to consumers with printers now costing under $200.
Medical applications of 3D printing include custom prosthetics and organ scaffolds.
Aerospace companies use 3D printing to manufacture lightweight parts for aircraft.
Correct Answer: B
Choice B. From 1980s industrial prototyping to $200 consumer printers shows evolution.
