Question

fff: bridging
use the information below to answer the question.
in 3d fff design, a bridge is a design technique that helps minimize or reduce support
structure by spanning the space between two points. the distance may vary from one
manufacturer to another, but the general rule of thumb is 1cm. if the print doesnt
work the first time using the default settings, there are a few things to adjust in the
slicing software.
fan speed
the first thing to do is increase the fan speed. increasing the fan speed will solidify the
molten polymer more quickly, building the structure as it goes. this will increase the
possibility of the bridge working the first time.
temperature
to increase the viscosity of the molten polymer, reduce the temperature by about 15
degrees. this will make the polymer thicker.
print speed
a user can slow down the rate at which the print head is moving. a user can also slow
down the rate at which the filament is going into the nozzle. less material will get
pushed out, so it is less likely to harden before it gets to the other side.
a design technique that helps minimize or reduce support
structure by spanning the space between two spaces is
known as what?
a bridge
a platform
a connector
a strap

Explanation:

The text defines a bridge in 3D FFF design as a technique to minimize support structures by spanning space between two points, which matches the question's description.

Answer:

a bridge
