Question

binder jetting technologies (bj)
use the information below to answer the questions to the right.
binder jetting requires no polymers. you can use sand or metal as your building agent. it also requires no direct heat.
the process of binder jet printing includes distributing a fine layer of powder onto the print bed. as each layer is spread, the print bed will lower until the final layer is distributed.
a binding agent is a liquid that takes powder and glues it together to make it stick together, and that is how you get the first layer and so on.
the print heads know where the binding agent is to be applied.
the binding agent will need to cure and harden, there is no laser or heat included in this process.
by not using any heat, we are eliminating any opportunity for any internal stress in your print.
on a binder jet printer, what lowers with each layer applied?
the heat on the material
the print bed
the print heads

Explanation:

The text states that in Binder Jet printing, as each layer of powder is spread, the print bed lowers until the final layer is distributed.

Answer:

the print bed
