Pre-test Module 8

What is the main purpose of creating a prototype in the product development process?

• To test function functions and validate the design

• To reduce the number of products produced

• To prepare the final project report

• To increase production costs

• To replace the role of the design team

What is the main difference between a physical prototype and an analytical one?

• Physical is used for computer simulation, while analytical is used for material testing

• Physical cannot be tested, analytical can

• Physical is a tangible artifact, analytical is based on mathematical models

• Physical is cheaper than analytical

• Physical is always faster to make

Which of the following is a principle of prototyping?

• Physical prototypes are not needed in testing

• Prototypes are only made at the end of the project

• Prototypes may accelerate other development steps

• Prototypes must not affect task structure

• Prototypes do not reduce cost risk

What technology underlies the basics of rapid prototyping process?

• CNC and VR

• CAD and 3D Printing

• CAM and Wireframe

• CAM and 3D Printing

• Rendering and Animation

What is the main benefit of 3D printing in prototype making?

• Slower design iteration process

• Higher material costs

• Cannot use CAD files

• Fast and cost-effective physical model creation
