3D Printing Quiz

What is 3D printing?

• The process of printing text on paper

• Creating a tangible 3D object from a digital file using a 3D printer

• A method of 2D digital printing

• Sculpting objects by hand from clay

Why is 3D printing also known as "additive sculpture"?

• Because it involves adding paint to sculptures

• Because it involves cutting and chiseling materials

• Because it prints in layers, adding material to create the object

• Because it uses a subtractive process to create objects

What is the first step in the 3D printing process according to the image?

• The 3D printer heats up to create a liquid material.

• A 3D digital file is created using a 3D modeling program.

• The file is sliced into hundreds or thousands of lines.

• The printer prints layer by layer until the file is finished.

How does the 3D printer create the final object?

• By slicing the digital file into lines.

• By creating a 3D digital file.

• By printing layer by layer until the file is finished.

• By using a 3D modeling program.

Which material does not emit toxic chemicals when melted, making it safe for classroom use?

• ABS

• PLA

• Both ABS and PLA

• Neither ABS nor PLA

What does CAD stand for?

• Computer Assisted Drawing

• Computer Aided Design

• Computerized Art Design

• Computer Assisted Development

Which program did we use for developing CAD designs to 3D print?

• Adobe Illustrator

• SketchUp

• AutoCAD

• Tinkercad

What is the name of the part of the 3D printer that melts the filament to create the print?

• Power Supply

• Controller LCD

• Nozzle/Extruder

• Bed Leveling Screws

What is filament in the context of 3D printing?

• A type of software used for designing 3D models

• Spools of plastic used for printing

• The surface on which 3D printing occurs

• A scaffolding for overhanging parts of a 3D print

Why is PLA used as a filament in 3D printing in our classroom?

• Because it produces toxic gases when melted

• Because it is the cheapest type of filament

• Because it does not produce toxic gases when melted

• Because it can be heated to very high temperatures
