Which statement is true about 3D printers according to the material?

• A. They can create physical three-dimensional objects from designs
• B. They always print on metal
• C. They cannot be used for prototypes
• D. They are designed only for education

Answer: (A)

3D printing works by turning a digital design into a physical object, building it layer by layer from materials such as plastics or resins, and sometimes metals. This ability to create tangible three-dimensional objects directly from a design is what the material describes, and it underpins essential uses like prototyping and rapid iteration. Printers are not limited to metal; plastics and resins are common, and they are used far beyond education, including in manufacturing, healthcare, and product development. The other statements misrepresent what 3D printers do, since they are not restricted to metal, are widely used to create prototypes, and serve many contexts beyond education.
