What is the main advantage of Rapid Prototyping (RP) in product development?

It allows for quick production of physical models from CAD data.

Fill in the blank: The initial version of a product from which other versions are developed is called a ______.

Prototype

True or False: Additive manufacturing processes only use solid materials as their base.

False. Additive manufacturing can use liquid, solid, and powder materials.

Riddle: I create parts layer by layer, using a laser or a nozzle to melt or extrude. What am I?

Additive Manufacturing

Which rapid prototyping system is known for using liquid materials to create solid parts?

Liquid-based RP Systems

Fill in the blank: In Electron Beam Machining (EBM), the electron beam is generated in a ______.

Vacuum chamber

True or False: Selective Laser Sintering (SLS) requires explicit support structures to build overhanging parts.

False. SLS does not require explicit support structures as the remaining powder acts as support.

What is the process called that involves selectively melting powdered materials to create 3D objects in additive manufacturing?

Selective Laser Melting (SLM)

Fill in the blank: The principle of ______ involves using a laser to scan and solidify a liquid photopolymer.

Photopolymerization

Which technique uses a high-energy electron beam to fuse metal powder particles in additive manufacturing?

Electron Beam Melting (EBM)
