3D Printing Vocabulary Study Guide

What is 3D Printing / Additive Manufacturing?

• A process where objects are created by cutting material away from a solid block.

• A manufacturing process where three-dimensional objects are created by laying down successive layers of material from a digital design.

• A method of creating flat objects measured by length and width.

• A technique used to quickly fabricate a scale model using subtractive processes.

Which part of the 3D printer pushes out melted filament to build the object?

• Build Plate

• Filament Feeder

• Extruder

• Hotend

What is the function of the Stepper Motor in a 3D printer?

• It heats the filament to melt it.

• It controls precise movements of the printer’s parts.

• It feeds the filament through to the extruder.

• It holds the filament in a roll.

What does the term "Mass Customization" refer to in the context of 3D printing?

• The ability to create identical products in large quantities.

• A concept where 3D printing can revolutionize manufacturing by allowing for personalized products and a return to individual craftsmanship.

• A process of creating flat objects measured by length and width.

• A technique used to quickly fabricate a scale model using 3D computer-aided design.

What is the role of the Hotend in a 3D printer?

• It is the surface on which the 3D print is made.

• It is the heated part of the extruder that melts the filament.

• It is the component that feeds the filament through to the extruder.

• It is the roll that holds the filament.

What is the primary advantage of Fused Deposition Modeling (FDM) in 3D printing?

• High cost

• Ease of use and affordability
