How does a 3D pen work?

• By using laser technology to create 3D images

• By using ink to draw on paper

• By blowing air onto a special paper to create 3D effects

• By heating and melting plastic filament to create 3D objects

What is the main component of a 3D pen?

• Paper roll

• Ink cartridge

• Battery

• Extruder

Explain the process of using a 3D pen to create a 3D object.

• Dip the pen in water and draw the object in 3D

• Blow air into the pen to create the 3D object

• Use the pen to cut out the shape of the object from a 3D template

• Heat the plastic filament and extrude it through the nozzle to create layers and build up the 3D object.

What safety precautions should be taken when using a 3D pen?

• Using the pen near water

• Touching the hot nozzle with bare hands

• Wearing protective gloves, avoiding contact with the hot nozzle, and keeping the pen away from flammable materials

• Leaving the pen unattended while it's on

How does the speed setting on a 3D pen affect the drawing process?

• It affects the rate at which the filament is extruded

• It affects the temperature of the pen

• It changes the color of the filament

• It determines the size of the paper used
