Question

multi jet fusion - hp
use the information below to answer the question.
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 75 - 100% 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 support structures. there is also less waste with the powder: because it is recyclable and can be reused in the next process (unlike the fdm process, where once the powder has been sintered).
during multi jet fusion, what will the re - coater arm do after each layer of a print?
options (partially visible): regardless...the parameters of the printer’s software; remove any loose powder still remaining on the base; heat the detail agent to better define shapes and curves; apply a fresh layer of powder across the surface

Explanation:

To answer the question, we refer to the text: "The re - coater arm will apply a fresh layer of powder across the surface after each layer." We then match this description with the given options.

Answer:

apply a fresh layer of powder across the surface
