💡 Hint

Common Mistakes

Confusing FDM with resin-based printing which uses liquid resin.

Thinking metal powder is used in FDM, which is used in other 3D printing methods.

FDM printers work by melting and extruding thermoplastic filament to build objects layer by layer.

Complete the sentence to explain the basic working principle of FDM.

3D Printing

In FDM, the printer [1] the filament and deposits it layer by layer to form the object.

💡 Hint

Common Mistakes

Choosing 'cools' which is the opposite of what happens to the filament.

Confusing the process with cutting or painting.

The filament is heated until it melts, then extruded to build the object layer by layer.

3fill in blank

hard

Fix the error in the description of the FDM printing process.

3D Printing

The FDM printer uses a laser to [1] the filament and build the object.

💡 Hint

Common Mistakes

Thinking FDM uses lasers like some other 3D printing methods.

Confusing 'melt' with the action of the printer nozzle.

FDM printers extrude melted filament through a nozzle; they do not use lasers.

4fill in blank

hard

Fill both blanks to complete the dictionary comprehension describing FDM steps.

3D Printing

fdm_steps = {1: 'Load filament', 2: 'Heat nozzle', 3: [1], 4: [2]

Drag options to blanks, or click blank then click option'

A'Extrude melted filament'

B'Cool layers'

C'Cut filament'

D'Scan object'

Attempts:

3 left

💡 Hint

Common Mistakes

Choosing 'Cut filament' which is not part of FDM printing steps.

Confusing scanning with FDM process.

After heating the nozzle, the printer extrudes melted filament and then cools the layers to solidify the object.

5fill in blank

hard

Fill all three blanks to complete the dictionary comprehension describing FDM printer components.

3D Printing

fdm_components = {'extruder': [1], 'build_plate': [2], 'filament': [3]

Drag options to blanks, or click blank then click option'

A'nozzle that melts and deposits material'

B'flat surface where object is built'

C'thermoplastic thread used as material'

D'laser source'

Attempts:

3 left

💡 Hint

Common Mistakes

Selecting 'laser source' which is not part of FDM printers.

Mixing up filament with build plate.

The extruder includes the nozzle that melts filament, the build plate is the flat surface for printing, and filament is the thermoplastic thread used as material.
