Exam Study Guide - Second Semester

A process of making a three-dimensional object from a digital file by layering material until the object is created. What is this process called?

• 3D printing

• Injection molding

• CNC machining

• Casting

A type of support that holds up unsupported areas that would collapse during the printing process. These supports are easy to remove after the object is finished printing. What are these supports called?

• Breakaway Support

• Permanent Support

• Adhesive Support

• Integrated Support

Layers of 3D material that stretch between two points without any support from below. This usually requires breakaway supports. What is this process called?

• Bridging

• Warping

• Retraction

• Stringing

A horizontal plate where the first layer is attached in a 3D printer. What is this plate called?

• Build Plate

• Extruder

• Filament Spool

• Nozzle

Stands for 'computer aided design' which is computer software that is used in 2D and 3D design. What is the abbreviation for this?

• CAD

• CAM

• CAE

• CNC

The process of setting the location and dimension of parts and sensors so they are known and consistent. This is part of the printer setup process. What is this process called?

• Calibration

• Alignment

• Slicing

• Extrusion

The part of the 3D printer where the extruder (print head) sits and moves around, usually along the x and y axis. What is this part called?

• Carriage

• Nozzle

• Filament Spool

• Build Plate

The part of the 3D printer that is responsible for pushing the filament along, melting it, and placing it on the bed to build the model. What is this part called?

• Extruder

• Heated Bed

• Stepper Motor

• Control Board

Serves as the ink for a 3D printer. A continuous plastic material that feeds through the extruder and is melted and reformed into a 3D model. What is this material called?

• Filament

• Resin

• Powder

• Paper

3D printing language. A G-Code has instructions that tells the printer what to print, including locations, temperatures, etc. What is this code called?

• G-Code

• PostScript

• HTML

• Python
