3D Printing Quiz

An overhang is a part of a model that is:

• supported underneath

• partially or fully unsupported underneath

• vertical

• floating

Which of the following overhang angles, from the vertical axis, would generally be acceptable for most 3D printing without adding support materials?

• 50

• 55

• 30

• 80

Bridging refers to: Mark only one oval.

• a 45 degree overhang between 2 points

• a horizontal wall

• a horizontal overhang that will print across 2 points

• a 90 degree overhang supported on one side

When bridging large distances without support material, you will notice: Mark only one oval.

• drooping of the model

• underextrusion

• good surface quality

• material burning around the nozzle

When orienting models for 3D printing, you should: Mark only one oval.

• ensure the largest surface area is on the print bed, regardless of any other design consideration

• always enable support material

• try to minimize the amount of overhanging feature over 30 degrees

• try to minimize the amount of overhang features over 45 degrees

To ensure good bed adhesion, you should. Mark only one oval.

• design a model with no overhangs

• minimize the surface area touching the print bed

• design a model with no bridges

• ensure there is sufficient area touching the print bed

If your model has a very small surface area touching the print bed, the model may. Mark only one oval.

• topple over during printing

• cause the slicing software to not generate a path

• adhere too well to the print bed

• have poor surface quality

The main factor that determines the temperature at which a printer is set to operate is. Mark only one oval.

• The size of the model

• the amount of overhangs on the model

• The filament material type

• The type of printer you are using

Which layer height setting would lead to the smoothest print surface? Mark only one oval.

• 0.1 mm

• 0.15 mm

• 0.2 mm

• 0.25 mm

Which layer height setting would lead to the shortest print time? Mark only one oval.

• 0.1 mm

• 0.15 mm

• 0.2 mm

• 0.25 mm
