Which of the following materials are used in additive manufacturing?

I. Metals

II. Ceramics

III. Polymers

• I only

• II only

• I and III only

• I, II, and III

True or false?

Composite materials are not suitable for 3D printing and only pure materials can be used.

• TRUE

• FALSE

Why are polymers a popular material for additive manufacturing?

• Because they are cheap, versatile, lightweight, and do not require extreme processing conditions

• Because they are heavy, which would make the resulting prints strong and durable

• Because they are expensive. Expensive things are always high-quality

• Polymers are not used in additive manufacturing - they are too weak

True or false?

Ceramics have excellent mechanical properties as well as good thermal and electric conductivity, making them suitable for the production of electronic components.

• TRUE

• FALSE

What is a significant advantage of using ceramics in additive manufacturing?

• They are lightweight and flexible

• They can withstand high temperatures and have low thermal conductivity

• They are inexpensive and easy to process

• They have high electrical conductivity

True or false?

Metals are the only materials that can be used in 3D printing processes.

• TRUE

• FALSE

Which of the following is NOT a useful property of metals in additive manufacturing?

• They can easily form wires and powders

• They have excellent thermal and electrical conductivities

• They can be processed under mild conditions

• The have excellent mechanical properties

Which of the following is a common application of polymers in additive manufacturing?

• Creating high-strength structural components

• Producing prototypes and models

• Manufacturing electronic circuits

• Developing high-temperature resistant parts

What would be the MAIN reason for developing your own ink?

• Conventional materials are expensive

• Conventional materials do not have the desired physicochemical properties

• Conventional materials are hard to obtain

• Conventional materials are just fine, we can always use them

Which of the following systems is most likely to be smart and/or functional?

• A polylactic acid and polyvinyl chloride blend

• A copper and tin alloy

• Graphene nanoparticles in a polylactic acid matrix

• Sodium chloride
