• III only

• I, II, and III

True or false?

The thicker the printed layer the closer to the final product the printed object is.

• TRUE

• FALSE

True or false?

Conventional manufacturing methods require careful and detailed analysis of object geometry while additive manufacturing does not.

• TRUE

• FALSE

True or false?

Most conventional manufacturing processes rely on pre-existing moulds and templates to obtain objects but some conventional manufacturing processes can create objects layer-by-layer by depositing materials.

• TRUE

• FALSE

Which of the following statements about the degrees of freedom afforded by additive manufacturing is true?

• Complete freedom along the x and y axes but not the z axis

• Complete freedom along the x, y, and z axes

• Complete freedom along the y and z axes but limited movement in the x direction

• Complete freedom only along the z axes as the printed object becomes taller and taller

What is the correct order of the additive manufacturing process chain?

• modelling, file conversion, printing, post-processing

• modelling, printing, file conversion, post-processing

• file conversion, printing, modelling, post-processing

• modelling, file conversion, post-processing, printing

True or false?

STL files can be directly printed.

• TRUE

• FALSE
