Explain the process of selective laser sintering (SLS) in additive manufacturing.

• SLS involves using a hammer to manually shape the material into the desired form.

• SLS uses a high-powered laser to fuse small particles of material into a 3-dimensional shape.

• SLS uses a low-powered laser to melt large chunks of material into a 2-dimensional shape.

• SLS relies on a chemical reaction to create the 3-dimensional shape.

How does additive manufacturing contribute to sustainability?

• It contributes to air and water pollution.

• It increases material waste and energy consumption.

• It has no impact on material waste and energy consumption.

• It reduces material waste and energy consumption.

Discuss the impact of additive manufacturing on traditional manufacturing processes.

• Additive manufacturing does not allow for complex designs

• Additive manufacturing is slower and less efficient than traditional manufacturing processes
