Learning Outcome: to know the use of various options in Cura Slicer

b) Arun is printing a mechanical part that needs to be strong and

durable using a slicing application. Explain how the following settings of Cura Slicer will affect the printed object's strength and time. (4) [U]

i. Infill density ii. Shell thickness

Ans. Infill density

● Higher density increases the strength and durability of the

object. It is suitable for mechanical parts but takes more

time and uses more filament.

● Lower density makes the object weaker but prints faster

with less material, suitable for decorative models.

Shells

● Thick shells improve the outer strength and surface quality

of the object, but increase print time.

● Thin shells reduce the print time but make the object more

fragile and likely to break.
