Common Mistakes

Confusing ironing with coloring or hardening the surface.

Thinking ironing makes the surface rougher.

Ironing is a technique used to smooth the top surface of a 3D print by passing the nozzle over it to reduce visible lines and imperfections.

Complete the sentence to explain how ironing is performed.

3D Printing

During ironing, the printer nozzle moves [1] over the top layer to smooth it.

💡 Hint

Common Mistakes

Choosing 'quickly' which can cause uneven surfaces.

Selecting 'randomly' which does not describe controlled movement.

The nozzle moves slowly over the top layer during ironing to evenly smooth the surface without causing defects.

hard

Fix the error in the statement about ironing temperature.

3D Printing

The ironing temperature is usually set [1] the printing temperature to avoid melting the plastic too much.

💡 Hint

Common Mistakes

Choosing 'above' which can cause over-melting.

Selecting 'equal to' which may not be optimal for smoothing.

Ironing temperature is set below the printing temperature to gently smooth the surface without causing excess melting or deformation.

hard

Fill both blanks to describe the effect of ironing speed and flow rate.

3D Printing

Ironing works best when the speed is [1] and the flow rate is [2] to avoid gaps or blobs.

💡 Hint

Common Mistakes

Choosing 'fast' speed which reduces smoothing quality.

Selecting 'high' flow rate which causes blobs.

Slow speed allows careful smoothing, and low flow rate prevents excess plastic from creating blobs during ironing.

💡 Hint

Common Mistakes

Using uppercase keys which changes parameter names.

Using incorrect syntax for dictionary comprehension.

This comprehension creates a dictionary with keys as the parameter names and values as the parameter names themselves, useful for initializing settings.
