Common Mistakes

Choosing ruler which is less precise for calibration.

Calipers are precise measuring tools used to check printed part dimensions during calibration.

Fix the error in the statement about bed leveling.

3D Printing

Bed leveling ensures the [1] is perfectly flat and at the correct distance from the nozzle.

💡 Hint

Common Mistakes

Confusing extruder or filament with the bed.

Bed leveling adjusts the print bed to be flat and properly distanced from the nozzle for good first layers.

Fill both blanks to describe a calibration step.

3D Printing

To calibrate extrusion, measure the filament length before and after extrusion and adjust the [1] setting if the length is [2] than expected.

💡 Hint

Common Mistakes

Mixing temperature with extrusion multiplier or confusing length direction.

If the filament extruded is shorter than expected, adjust the extrusion multiplier to correct the flow.

💡 Hint

Common Mistakes

Using wrong comparison operators or keys without transformation.

This comprehension creates a dictionary of tests where the value meets or exceeds the target, using the test name in uppercase as the key.

Practice

1. What is the main purpose of calibrating a 3D printer?

easy

A. To ensure prints are accurate and reliable

B. To change the printer's color settings

C. To increase the printer's speed only

D. To update the printer's software

Solution

1. Step 1: Understand calibration meaning

   Calibration adjusts printer settings to improve print quality and accuracy.

2. Step 2: Identify main goal of calibration

   The goal is to make prints accurate and reliable, not just speed or color.

3. Final Answer:

   To ensure prints are accurate and reliable -> Option A

4. Quick Check:

   Calibration = Accurate prints [OK]

Hint: Calibration means making prints accurate and reliable [OK]

Common Mistakes:

• Confusing calibration with software updates
• Thinking calibration only changes print speed
• Assuming calibration changes print colors

2. Which step is NOT part of basic 3D printer calibration?

easy

A. Bed leveling

B. Nozzle height setting

C. Extrusion tuning

D. Changing filament color

Solution

1. Step 1: List common calibration steps

   Bed leveling, nozzle height, and extrusion tuning are key calibration steps.

2. Step 2: Identify unrelated option

   Changing filament color is not a calibration step; it's a material choice.

3. Final Answer:

   Changing filament color -> Option D

4. Quick Check:

   Calibration ≠ Changing filament color [OK]

Hint: Calibration adjusts printer settings, not filament color [OK]

Common Mistakes:

• Mixing filament changes with calibration steps
• Thinking color affects calibration
• Ignoring extrusion tuning as calibration

3. If a 3D printer's nozzle is set too high above the bed during calibration, what is the likely print result?

medium

A. The print will be perfectly smooth

B. The printer will print faster

C. The first layer will not stick well to the bed

D. The filament will over-extrude

Solution

1. Step 1: Understand nozzle height effect

   Nozzle too high means filament can't properly stick to the bed.

2. Step 2: Predict print outcome

   First layer adhesion will be poor, causing print failures or warping.

3. Final Answer:

   The first layer will not stick well to the bed -> Option C

4. Quick Check:

   Nozzle too high = Poor bed adhesion [OK]

Hint: Nozzle too high means filament won't stick well [OK]

Common Mistakes:

• Assuming print speed changes with nozzle height
• Confusing extrusion amount with nozzle height
• Expecting perfect prints despite wrong nozzle height

4. A user notices their 3D prints are too thin and fragile. Which calibration step should they check and possibly adjust?

medium

A. Extrusion multiplier or flow rate

B. Bed leveling

C. Nozzle temperature

D. Print speed

Solution

1. Step 1: Identify cause of thin prints

   Thin, fragile prints often result from too little filament being extruded.

2. Step 2: Match cause to calibration step

   Extrusion multiplier or flow rate controls how much filament is pushed out.

3. Final Answer:

   Extrusion multiplier or flow rate -> Option A

4. Quick Check:

   Thin prints = Check extrusion flow [OK]

Hint: Thin prints? Adjust extrusion flow rate [OK]

Common Mistakes:

• Only adjusting bed leveling for print thickness
• Ignoring extrusion settings
• Changing temperature without checking extrusion

5. During calibration, a user wants to ensure the printer extrudes exactly 100 mm of filament when commanded. They measure 90 mm extruded. What adjustment should they make?

hard

A. Lower the bed temperature

B. Increase the extrusion multiplier to compensate

C. Raise the nozzle height

D. Decrease the print speed

Solution

1. Step 1: Understand extrusion measurement

   User commands 100 mm but only 90 mm extrudes, so extrusion is too low.

2. Step 2: Choose correct calibration fix

   Increasing extrusion multiplier tells printer to push more filament, fixing under-extrusion.

3. Final Answer:

   Increase the extrusion multiplier to compensate -> Option B

4. Quick Check:

   Less filament extruded? Increase extrusion multiplier [OK]

Hint: Extrude less than commanded? Raise extrusion multiplier [OK]

Common Mistakes:

• Changing bed or nozzle settings unrelated to extrusion length
• Reducing print speed instead of adjusting extrusion
• Ignoring extrusion calibration step
