Exploring 3D Printing and Pens

What is 3D printing?

• 3D printing is a way to produce sound waves digitally.

• 3D printing is a technique for creating flat images.

• 3D printing is a process of creating three-dimensional objects from digital files by adding material layer by layer.

• 3D printing is a method of painting on surfaces.

Name one common material used in 3D printing.

• ABS

• PETG

• PLA

• Nylon

What is a 3D pen used for?

• Writing with ink

• A 3D pen is used for creating three-dimensional objects.

• Creating 2D images

• Drawing on paper

List one advantage of using 3D printing.

• Limited design flexibility

• High material waste

• Slow production speed

• Rapid prototyping

What safety gear should you wear when using a 3D printer?

• Safety boots, earplugs, and a helmet.

• Safety goggles, gloves, and a mask.

• Sunscreen, flip-flops, and a baseball cap.

• Knee pads, reflective vest, and a hard hat.

What is PLA in the context of 3D printing materials?

• PLA refers to a printing technique called Layered Printing Architecture.

• PLA is a type of metal used in 3D printing.

• PLA stands for Polyethylene Terephthalate.

• PLA stands for Polylactic Acid.

Describe a basic technique for using a 3D pen.

• Fill the pen with water before use.

• Insert filament, heat the pen, and extrude while moving to create 3D designs.

• Use the pen like a regular marker without filament.

• Draw directly on paper without heating the pen.

Why is it important to keep the 3D printer clean?

• It is important to keep the 3D printer clean to ensure optimal performance and print quality.

• To make the printer look more aesthetically pleasing.

• To reduce the printer's energy consumption.

• To increase the printer's weight for stability.

What temperature does a typical 3D printer extruder reach?

• 180°C to 250°C

• 300°C to 350°C

• 400°C to 450°C

• 50°C to 100°C

How can you prevent burns when using a 3D pen?

• Leave the pen unattended while it heats up.

• Hold the pen by the handle and avoid touching the nozzle.

• Use the pen without a handle for better control.

• Touch the nozzle to check the temperature.
