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 15% faster 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 the 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.
to increase the heat source for multi jet fusion, where is a fusion agent laid down?

• the support structure
• the print bed
• the materials
• the re - coater arm

Explanation:

To answer the question, we refer to the text: "On the print bed, a fusion agent is laid down, which increases the heat source in that area." This directly tells us where the fusion agent is laid down to increase the heat source for Multi Jet Fusion.

Answer:

B. the print bed
