💡 Hint

Common Mistakes

Choosing 'lower' because PLA is rigid.

Confusing flexibility with strength.

PETG is more flexible than PLA, making it less brittle and better for parts that need some bend.

2fill in blank

medium

Complete the sentence about PETG's temperature resistance.

3D Printing

PETG typically has a glass transition temperature around [1] °C.

💡 Hint

Common Mistakes

Choosing 60°C which is PLA's Tg.

Confusing melting point with glass transition temperature.

The glass transition temperature of PETG is about 80°C, meaning it softens around this temperature.

3fill in blank

hard

Fix the error in the statement about PETG's moisture absorption.

3D Printing

PETG absorbs moisture [1] than nylon, making it easier to print.

💡 Hint

Common Mistakes

Choosing 'more' because nylon is very hygroscopic.

Confusing moisture absorption with water resistance.

PETG absorbs less moisture than nylon, so it is less prone to printing problems caused by moisture.

4fill in blank

hard

Fill both blanks to describe PETG's strength and transparency.

3D Printing

PETG is [1] than ABS in impact strength and [2] naturally transparent.

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

Astronger

Bweaker

Cnot

Dis

Attempts:

💡 Hint

Common Mistakes

Choosing 'weaker' for strength.

Choosing 'not' for transparency.

PETG is stronger than ABS in impact resistance and is naturally transparent, unlike ABS which is opaque.

5fill in blank

hard

Fill all three blanks to complete the PETG printing temperature range and adhesion property.

3D Printing

Recommended printing temperature is [1] °C, bed temperature is [2] °C, and PETG [3] to most build surfaces well.

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

A230-250

B70-80

Csticks

Ddoes not stick

💡 Hint

Common Mistakes

Choosing too low or too high temperatures.

Saying PETG does not stick well, which is false.

PETG prints best between 230-250°C, with a heated bed around 70-80°C, and it sticks well to most build surfaces.
