A+ OBJECTIVE 3.7 HARDWARE – 3D PRINTERS

1 / 16

How are prototypes created rapidly using 3D printers?

By using traditional printing methods

By adding layers to create the prototype

By subtracting layers from the final product

By grinding down metal

2 / 16

What type of 3D printing is commonly known as Fused Deposition Modeling (FDM)?

Filament printing

Selective Laser Sintering (SLS)

Stereolithography (SLA)

Resin printing

3 / 16

What happens to any excess resin in resin printing?

It is hardened by ultraviolet light

It is disposed of easily

It is managed by the print head

It is removed before the next layer is printed

4 / 16

What is used to harden the resin in resin printing?

Ultraviolet light or laser

Liquid adhesive

Print head connection

Melting process

5 / 16

What is something that’s very easy to dispose of in filament printing?

The build platform

The excess resin

The long strands of filament

The liquid resin

6 / 16

Why is protective gear required in resin printing?

To create a larger print bed

To manage the filament

To dispose of the excess filament

To protect against injury from working with liquid resin

7 / 16

What is the term often used to describe the process of creating output with a 3D printer?

Traditional printing

Additive manufacturing

Layered manufacturing

Subtractive manufacturing

8 / 16

What is the purpose of the build platform in resin printing?

To apply ultraviolet light to harden the resin

To move down into the liquid resin

To create layers on the object

To manage the filament

9 / 16

What is the primary method used in filament printing to create a 3D object?

Applying ultraviolet light to harden the resin

Moving the build platform up and down

Melting the filament and placing it in layers

Using resin to create layers

10 / 16

What advantage does filament printing have over other types of 3D printing?

Requires the use of hazardous materials

Produces smoother and more detailed objects

Creates little mess and is easy to dispose of

Works with a liquid resin and a build platform

11 / 16

What is the purpose of a print bed in 3D printing?

To create layers on the object

To connect with the print head

To provide a flat and level surface for printing

To apply adhesive to the surface

12 / 16

What is the biggest challenge with resin printing?

Managing the liquid resin

Creating smooth and finely detailed objects

Finding a large print bed

Disposing of the filament

13 / 16

How does the build platform move in resin printing?

It melts the filament and places it in layers

It connects with the print head

It moves up and down into the liquid resin

It applies adhesive to the surface

14 / 16

What is the primary feature of a 3D printer?

It creates output by subtracting layers

It prints in two dimensions

It prints in three dimensions

It uses traditional printing methods

15 / 16

How does the print head create a 3D object in filament printing?

By moving up and down

By managing the filament

By melting the filament and placing it in layers

By applying ultraviolet light

16 / 16

What is a characteristic of the print bed in filament printing?

It needs to stay completely still during printing

It is small and compact

It is made from liquid resin

It requires protective gear to handle
