Question

multi jet fusion - hp
use the information below to answer the questions
multi jet fusion is similar to sls in that it uses powder and a heat source, but these components are used differently.
on the print bed, a fusion agent is laid down, which increases the heat source in that area. a detail agent is also applied, which helps define the edge, creating a sharper print. the heat source moves over the material, working one line at a time, similar to a scanner. this will create the first layer.
the re - coater arm will apply a fresh layer of powder across the surface after each layer. this is followed by the fusion agent, the detail agent, and the heat source.
advantages
this process is 25 - 30% quicker than sls. because of the fusion agent, there isn’t as much heat - up time and cool - down time, so time is saved in the print cycle. this process also allows users to print using more than one color. however, the range of colors is proprietary.
like sls, multi jet fusion does not need a support structure. there is also less waste with this powder because it is recyclable and can be reused in the next process unlike the sls process where it is hard to repurpose the powder once it has been sintered.
how does the heat source move over the material during multi jet fusion?
one line at a time
one half at a time
one print at a time
one angle at a time

Explanation:

From the text: "The heat source moves over the material, working one line at a time, similar to a scanner." So we find the option that matches this description.

Answer:

A. one line at a time
