Layer adhesion problems in 3D Printing - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to identify the main cause of poor layer adhesion in 3D printing.

3D Printing

The primary cause of poor layer adhesion is [1] temperature.

💡 Hint

Common Mistakes

Choosing 'high' temperature which usually improves adhesion.

Low printing temperature causes layers not to bond well, leading to poor adhesion.

Complete the code to fix layer adhesion by adjusting the {{BLANK_1}} speed.

3D Printing

Reducing the [1] speed can improve layer bonding.

💡 Hint

Common Mistakes

Choosing 'travel' speed which does not affect layer bonding directly.

Slowing down the print speed allows layers to bond better as the filament has more time to fuse.

Fix the error in the statement about cooling fans affecting layer adhesion: "Turning the fan {{BLANK_1}} can help improve adhesion."

3D Printing

Turning the fan [1] can help improve adhesion.

💡 Hint

Common Mistakes

Choosing 'on' which cools the filament too quickly and weakens adhesion.

Turning the cooling fan off or reducing its speed prevents rapid cooling, which helps layers bond better.

Fill both blanks to create a dictionary comprehension that maps filament types to their recommended {{BLANK_1}} and {{BLANK_2}} settings for better adhesion.

3D Printing

settings = {filament: {'temperature': temps[filament][1]2, 'speed': speeds[filament][2]2} for filament in ['PLA', 'ABS']}

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

💡 Hint

Common Mistakes

Using '*' or '//' which are not suitable for simple addition or subtraction.

The '+' operator concatenates strings or adds numbers, and '-' subtracts. Here, adding 2 to temps and subtracting 2 from speeds adjusts settings for adhesion.

5fill in blank

hard

Fill all three blanks to create a dictionary comprehension that filters filament types with adhesion issues where temperature is {{BLANK_1}} 200, speed is {{BLANK_2}} 50, and fan is {{BLANK_3}} False.

3D Printing

issues = {f: {'temp': t, 'speed': s, 'fan': f_on} for f, t, s, f_on in data if t [1] 200 and s [2] 50 and f_on [3] False}

💡 Hint

Common Mistakes

Mixing up comparison operators or using '!=' which would select the wrong data.

Filtering for temperature less than 200, speed greater than 50, and fan off (False) helps identify adhesion problems.
