Print speed refers to...

the time it takes to print a single layer

the speed at which the feeder pushes filament through the nozzle

the speed at which the print head travels when printing

the speed at which the print head travels when not extruding

If you are experiencing underextrusion on the outer walls, one of the things you might try is...

reducing the print temperature

switching the printer on and off

calibrating the printer

lowering the print speed

Which of the following comments is NOT true?

the bottom layer should not be squashed onto the print bed

the bottom layer is the most important layer in a 3D print

a low print speed will help the bottom layer stick to the print bed

rafts and brims are bases that help with print bed adhesion

The main factor that affects the correct print temperature is:

the size of the model

the type of printer you are using

the material type

the amount of overhangs on the model

Printing with an excessively high temperature can cause...

underextrusion

unwanted oozing of the nozzle

cracks in the model

To achieve the optimal surface quality, print with the...

highest temperature possible that does not cause overextrusion

fastest print speed possible that does not cause underextrusion

lowest temperature possible that does not cause underextrusion

When printing a model with multiple bridges and no support material, you should consider...

using a higher layer height so the strands of filament bridging the gap will be stronger

using a lower layer height so the strands of filament bridging the gap are lighter

printing with a higher temperature to ensure enough filament comes out to bridge the gap

Which of the following statements is true?

a higher layer height will take longer to print than a lower layer height

a higher layer height generally gives a better surface finish than a lower layer height

a lower layer height generally gives a better surface finish than a higher layer height

When looking for a smooth surface quality, using a low layer height is especially important if...

the model is large

the model has many curves in both the horizontal and vertical axes

the model has several areas of bridging

A common tip is to orientate your model...

so that it is the tallest it can be

to minimise the amount of overhangs over 45 degrees

so that the largest surface area is touching the print bed no matter what

Increasing the shell thickness will...

reduce the print time

make the print stronger

ensure you can always print models hollow

To fix ‘pillowing’ you can...

increase the bottom/top thickness

decrease the bottom/top thickness

decrease the amount of infill
