• Rapid prototyping
• computer-aided design
• 3D printing , CNC machining, or laser cutting.
• test
• Modelling
• cardboard, tape, foam core.
• finish

What are advantages of rapid prototyping in industry? Select all correct answers.

• Speed: Designs can be created and tested much faster than traditional methods.

• Cost-effective: Reduces costs by minimising waste and avoiding expensive tooling.

• Flexibility: Easy to modify and test different versions of a product.

• Improved accuracy: Produces high-detail models that can be tested before final production.

• Rapid prototyping guarantees that every design will work perfectly on the first try.

What are disadvantages of rapid prototyping in industry?

• Material limitations: Some rapid prototyping materials are not as strong or durable as final production materials.

• High initial costs: 3D printers and other rapid prototyping machines can be expensive.

• Environmental impact: Some materials used (e.g., plastic filaments) may not be biodegradable and can contribute to waste.

• Environmental impact: Making parts and changing them contributes to landfill.

• Every material can be used in rapid prototyping, including glass and fabric.

Answer explanation

3D componants may end up in landfill, but by testing a part and ensuring it will be successful before entering mass production, higher amounts of waste in the long term may be avoided.

How has rapid prototyping changed the way companies design?

• Reduce manufacturing costs

• Develop products faster

• Experiment with complex designs

• Reduces the time and cost associated with product development, as it allows for faster iteration and testing of designs

• Reduces material waste by building products layer by layer.

What effect does rapid prototyping have on the environment?

• Rapid prototyping has no impact on the environment.
• Rapid prototyping can have a positive effect on the environment by reducing material waste by identifying design flaws early.

• Rapid prototyping eliminates all material waste.
• Rapid prototyping only increases pollution without any benefits.

What effect does rapid prototyping have on the economy?

• Rapid prototyping leads to increased unemployment rates.
• Rapid prototyping has no impact on product quality.
• Rapid prototyping decreases the speed of market entry for new products.
• Rapid prototyping stimulates economic growth by improving speed in product development.

How could you use rapid prototyping principles to help you design your light?

• Create 3D models to test the size, shape, and functionality of the design.

• Experiment with different materials to see which works best for the light’s structure and aesthetics.

• Test different components such as shades, stands, and fittings before finalising the design.

• Refine usability to make sure the light is practical and easy to use.
