\3d printers eliminate the need to manufacture a block of metal before the tooling process even begins. instead, the raw materials for 3d printers are easy - to - produce pellets, powders, pastes, or liquids. the printers can use lasers, uv lights, and other setting tools to finalize each layer. 3d printing may allow for tiny support structures to be added throughout. this makes the part strong where it needs to be strong and less so where the forces wont be as great. the new design may look like an intricate skeleton - just as strong but much lighter and using less material.\ what can you infer from this paragraph about 3d printing? a) since 3d - printed items use less material, theyre weaker than items manufactured by other methods. b) workers must go through an extensive training process to correctly operate 3d printers. c) 3d printers have significant advantages over traditional manufacturing methods. d) 3d printing isnt a practical manufacturing method for modern needs.

Answer

Brief Explanations:

The paragraph mentions that 3D - printers eliminate the need for pre - manufacturing metal blocks, use easy - to - produce raw materials, can add support structures for strength optimization, and create lighter designs with less material. These are all advantages over traditional manufacturing methods. Option A is incorrect as the text says 3D - printed parts can be as strong. Option B has no mention of worker training in the text. Option D is contrary to what the text implies.

Answer:

C. 3D printers have significant advantages over traditional manufacturing methods.
