Question

sls: printer characteristics
use the information below to answer the question.
layer adhesion
like most 3d printing technologies, sls will create each layer one at a time. in this
type of process, good layer adhesion is quite crucial. it is important to make sure the
powder is preheated and there is a good fusion between layers.
sls machine components
while there are many different components used in a sls system, there are three
major parts that operators should be aware of

• the laser scanner will sinter the printed form layer by layer.
• the re - coater will spread a layer of powder onto the build table after each scan

done by the laser

• the build plate will move down with the creation of each layer

what is the re - coater used for in the sls process?
to spread a layer of powder onto the build table
to move down with the creation of each layer
to offer a support structure to the form
to sinter the printed form layer by layer

Explanation:

From the "SLS Machine Components" section, it is stated that "The re - coater will spread a layer of powder onto the build table after each scan done by the laser". So we can find the function of the re - coater from this description.

Answer:

to spread a layer of powder onto the build table
